From Romans to Roses Some reflections during a walk round the city off the beaten track Gerald Bettridge

Lyon’s historic past dates back 2000 years. From the old theatres to the new Confluence district it is a surprising and fascinating city, but one has to take the time to search out its hidden charms. Gerald Bettridge, an Englishman who fell under its spell many years ago, will take you on a tour off the beaten track to seek out what constitutes the essence of this town. From the medieval Abbaye d’Ainay, hidden away between the two rivers the Rhône and Saône, you will cross the bridge to Lyon old town and its Renaissance district almost intact for centuries. In this part of the city, there are typical streets named traboules like passages that pass through buildings and link streets. Houses were built on four or five floors with interior courtyards and lovely staircases and galleries, many of which show the influence of the Italians who were such key trading partners at the time. Then he will take you up to Fourvière. At the top of this hill is where the Romans founded the city in the 1st century B.C as the capital of the Three Gauls. There you will discover some important remains such as old roman theatres, and the aqueduct not far from the site of the forum, today the location of the basilica of Notre Dame de Fourvière and the chapel dedicated to Thomas Becket. The walk will take you along the path of the funeral processions to the cemetery of Loyasse where the local notables are buried.

The region of Lyon was one of the main European centers for At the end of the 19th century Lyon was called the capital of roses. horticultural breeding during the 19th century, and at the beginning In 1845, Claude Ducher organized the first exhibition dedicated to roses in Lyon at Palais Saint Pierre. He went on to of the 20th. Thousands of flowers, fruits or vegetables varieties establish his permanent nursery in Lyon in this wonderful area which was the birth place of many great rosarians were created between 1830 and 1960, ranging from new potatoes creating some of the world’s most gorgeous and coveted roses. through to new orchids. This remarkable context, stemming from Claude Ducher’s artistry and craftsmanship remained very important in the world of hybridizing roses. His research geographical, historical and botanical local specificities, allowed and resulting creations brought significant progress in the evolution of roses. So many great varieties, such as ‘Rêve the development of outstanding characters, such as the Guillot and d’Or’, ‘Gloire de Ducher’, ‘Mlle Cécile Brunner’ and many others are still appreciated by worldwide collectors. Pernet- Ducher families, still considered as uncommon breeders. Within the field of roses, Lyon’s horticulture made a notable name Later on, his son in law, Joseph Pernet Ducher, added to his legacy in creating yellow, orange colored roses. for itself, since about 60% of the world varieties as of 1850 had been In the modern era, Etienne Bouret, famous photographer and rose expert and Fabien Ducher, rose breeder who is the created in this region. 6th generation of the Ducher Family, are going to introduce you this incredible story… This historical insight is based on the scientific work of Stéphane Crozat for the National Center For Research and Science (CNRS) from 2003 to 2008 and later, for the Centre de Ressources de Botanique Appliquée (CRBA), in Lyon. Based on historical documents from the 16th century to nowdays you will discover how Fabien Ducher and why the city of Lyon and the close suburbs held the leed for horticultural works.

Two centuries of roses: the Guillot creations Mallerin, the prince of color

Jean-Pierre Guillot Robert Laperrière

In the 19th century in Lyon, the Guillot family played Charles Mallerin (1878-1960) is a particularly important link in the unbroken succession of rose breeders of Lyon and its a huge part in the field of rose development and then surroundings, from the early years of the 19th century until today, who still enhance by their research the genus Rosa. in the fame of the city. Jean Baptiste Guillot Father Installed in Varces, near Grenoble, he was the breeder of many varieties, roses full of elegant flowers with delicate settled down in Lyon in 1829 and will be one of the or bright colors. His first creations appeared in 1925, he was then only a connoisseur who was engaged in creation. first along with Plantier to develop the culture f rose He quickly gave up his engineering profession and devoted himself to his passion. He was more an artist than a true in Lyon. professional, because all that mattered to him was the color and shape of flowers. His creations influenced many rose In 1849, the invention by Jean Baptiste Guillot Father growers and breeders who took more or less inspiration from his results. He was not offended, on the contrary he was of the technique of budding on wild roses will make happy to show his visitors his latest creations. We can say that Mallerin became a professor, his advice, his opinions the rose culture economically profitable and will were appreciated and often implemented. Indeed, from 1935 for more than 20 years many amateurs and professionals, enable its development. In 1842, Jean Baptiste Guillot both French and foreign, came to Varces. Charles Mallerin welcomed, among others, Meilland, Dorieux, Laperriere. Father created the rose called ‘Lamartine’. This was The descendants of these 3 families are still present and active among the 10 breeders in our area. the first of a wide range of creations such as the rose His influence is still present today, because among the current varieties, some are enhanced by a distant connection ‘La France’ created in 1867 which was the first hybrid with Mallerin’s roses. tea rose. In 1875 with seeds coming from Japan and after many tests of crossings, Jean Baptiste Guillot ‘La France’ - J.B. Guillot fils (1867) Son obtained the first Polyantha rose bush named Robert Laperrière ‘Paquerette’. The Guillot family took a unique place in the world of rose culture thanks to many creations realized until 2011, when Roseraie LAPERRIERE Jean-Pierre Guillot, who had no heirs, sold his company to a specialized society which exists today under the name Route Nationale 6 Roseraie Guillot. The resumption in 2011 of this illustrious mark imposed the implementation of an ambitious program 38070 Saint-Quentin-Fallavier so that the GUILLOT company can approach the 21st century on a renewed dynamics. Multiple investments were realized to redefine the orientations of the research, modernize the production tool and finally expend a marketing strategy fitted to the evolution of the market.

It is the youngest of the large rosaria in Germany. The rosarium itself is an integrative part of the Westfalenpark, and features more than 2,500 rose species and cultivars. The rose beds and thematic rose gardens are arranged along the so called “Walk of Roses”. The Rosarium Uetersen in the North of Germany covers 5.2 hectares and features about 30,000 rose bushes in 900 species and cultivars.

Rose genomics and perspectives Mechanisms of polyploidization

Mohammed Bendahmane Benjamin Govetto, Manuel Le Bris

Roses are of high symbolic value and great cultural importance in different societies worldwide. Roses are widely The genus Rosa, comprising around 200 species, has the particularity to show a high richness in polyploids (organisms used as garden ornamental plants, as cut flowers and for the production of essential oil for the perfume and cosmetic owning more than two sets of chromosomes) ranging from diploid up to decaploid species. industries. Breeding of roses involved crosses between different European, Asian and Middle-Eastern rose species. In spite of the wide diversity in Rosa, only a dozen of wild species would have contributed in modern roses, explaining Several characters of high economic values, involving mainly floral quality, plant architecture and disease resistance, their relatively limited genetic background. Interspecific hybridizations with new wild species, in the aim of were selected during rose domestication and subsequent improvements. introgressing new traits and broadening the modern rose genetic background, are actively sought by plant breeders. During the past decade the deciphering of the genome of many plant species have provided scientists with a framework However, the differences in ploidy level between wild species (mostly diploids) and cultivars (mostly tetraploids) often to understand how plants grow and interact with their environment. In the frame of an international scientific lead to a sterile offspring. A promising pathway to overcome this ploidy barrier is the fertilization of tetraploid cultivars consortium, we initiated the determination of the genome sequence of the rose. Such information is expected to with diplogametes (“unreduced” gametes with somatic chromosome number) induced in wild species. However, the facilitate and speed up scientific research to understand the molecular and genetic mechanisms underlying important knowledge of polyploidization mechanisms (e.g. the cytological events, the inductive environmental cues or the genetic traits in Rosa (flowers, plant architecture, disease resistance, etc.). Rose breeding is time consuming, especially for factors) is still limited in plants. Before being able to develop routine tools in rose breeding using diplogametes, more complex traits, and the outcomes are usually unpredictable. The gained knowledge will also help predicting plant data and information about their formation need to be collected. characters through DNA sampling and tests (DNA marker-assisted breeding) and therefore to substantially improve In this context, both environmental and developmental conditions able to reproducibly induce a high production of male breeding. Besides the economic importance, the gained knowledge is also of scientific interest. The rose is well suited diplogametes were recently identified in Rosa in our lab. A short exposure of high temperatures in early meiosis is to be a model organism for woody ornamental species. The importance of a rose genome sequence and its potential sufficient to trigger the formation of diplogametes. From this perfectly reproducible rose biological model, cytological uses for the rose and for other related species, will be discussed. changes leading to diplogametes were observed: mainly microtubule re-orientations in metaphase in meiosis II, a few cytomixis events and complete omissions of the second meiosis are not excluded. As some of these modifications phenocopy Arabidopsis mutants, orthologous genes are studied in Rosa. In addition, potential new pathways are also investigated by comparing the differentially expressed genes in Rosa. All these discoveries might allow to open up new opportunities in rose breeding: e.g. in breeding genotypes highly producing diplogametes, or in stimulating a high production of diplogametes by playing with both climatic conditions and developmental stages. By providing easy access to still unexploited wild resources, Modern rose might benefit from such new tools.

Annick Dubois Fabrice Foucher

Wild and cultivated roses harbor a huge diversity of flower morphologies, colors and scents, making them a particularly In rose, recurrent blooming has played an important role in the success of roses. Once flowering roses flower only in intriguing model for the study of natural and artificial evolution of floral traits. How are rose flowers forming? Behind spring, whereas recurrent roses have the ability to flower several times a year. Among recurrent roses, some roses this apparently trivial question lies particularly complex research, as we know very little yet about the biology of this (as modern roses or old Chinese variety as ‘Old Blush’) can flower continuously. We have demonstrated that the ornamental perennial. Wild rose’s floral diagrams harbor very high organ numbers, which allows for a variety of continuous-flowering phenotype is due to a genetic mutation in a gene encoded a floral repressor. In once-flowering morphology changes observable in our garden roses. How do we tackle this question at the basic research level? roses, the production of this floral repressor is seasonally regulated. The molecule is not produced in spring allowing How do we - geneticists and molecular biologists - revisit the rose floral diagram? Our group at ENS-Lyon focuses on blooming to take place. Then after the blooming period, all the new emerging shoots produce the repressor and are floral architecture, especially on the genetic control of petal size and petal number. While wild roses all have 5 petals, unable to flower again till the next spring. most cultivated roses have double flower ranging from 10 to as many as 200 petals. In continuous-flowering plants, the gene encoded the floral repressor is mutated by the insertion of a large DNA Using morphological analysis and microscopy we described the first stages of floral organogenesis in roses. Our element, called copia, in the gene sequence. Due to the insertion of this copia element, the roses could not anymore approach to study flower architecture was based on the existing background knowledge in model plants and on the accumulate the repressor, and consequently they flower continuously. Furthermore, we have demonstrated that this analysis of gene expression at the very first steps of floral development. We compared gene expression in simple vs. mutation is reversible. In the climbing mutants, as ‘Old Blush Climbling’, the copia element is replaced by a shorter double rose flowers, and we showed that differences in the regulation of the rose AGAMOUS gene could explain the element. The climbing rose mutant can then accumulate the repressor and cannot flower continuously. differences in phenotype. From these results, we drew a genetic model explaining the changes in double rose flower The continuous-flowering mutation was introduced in Europe from old cultivated Chinese roses and progressively architecture. By a combination of genetic, molecular and transcriptomic approaches we now seek possible causes selected during the 19th century, leading to the modern roses. We draw new hypothesis concerning the origin of explaining the AGAMOUS differential regulation in the double flowers. In the course of this study, we built a series of recurrent blooming in Rosa moschata and Rosa rugosa. Their ability to flower several times a year could be explained tools to study molecular biology and genomics which will be useful to study other traits in roses. by a different regulation of the gene encoded the floral repressor. The floral repressor is less accumulated than in once-flowering roses, and new blooming is possible in summer or in autumn. By studying this floral repressor, we bring new knowledge on the physiology of flowering in rose and the different environmental and endogenous factors that affects blooming.

But this particular situation may cause some technical problems: • To control plant shape by cultivation techniques such as water restriction in order to respond to consumers’ • Monoculture of the rose inexorably leads to tired soil preferences. • The density of plantation involves significant lopping and pruning • The lack of vigour of some of the very old varieties require great vigilance and regular multiplication programs • The “zero-phyto” politic is sometimes difficult to reach in relation to conservation missions objectives… When presenting the rose garden, the Val-de-Marne will discuss these problematics and will explain the means implemented for the conservation of this remarkable garden.

The Noisette rose project in France Fragance, from the scientific point of view

Bernard Mandô, Mathilde Liorzou Sylvie Baudino-Caissard

Created by Jules Gravereaux, the Roseraie du Val de Marne de l’Haÿ, located 10 km south of Paris, is the largest The rose is the queen of flowers and its fragrance has enchanted man since the Greek antiquity. Roses are widely used historic rose garden of France. Noisettes roses are of particular interest. They had a parallel American and French as garden plants and for the cut flower market. They are also used for the production of essential oil for the cosmetic early development and represented in the 1810-1830 an original new group of reblooming roses with climbing habits. and perfume industries. A lot of botanical roses are scented and use their perfume to attract pollinators. From our collection of 70 Noisettes, we established a core-collection for the conservation of the group. We brought It has been shown that odour emission follows a circadian rhythmicity, with a diurnal peak. This is because roses together many old documents and pictures, from books, magazines and catalogues, for comparisons. A huge number are pollinated by diurnal insects like bees.

In spite of numerous chemical studies of rose scent, the biosynthetic pathways of many compounds are unknown. In modern roses or Tea Hybrids, scent is mainly produced in petals, although stamens can also contribute to the emission. We showed that the scent compounds are concentrated in epidermis of the petals, probably in small lipid droplets. We are also studying several genes involved in the biosynthesis of scent in rose. For example, we recently characterized the enzymes responsible for the so-called “tea scent” emitted by Chinese roses. We are also interested Bernard Mandô in genes involved in the scent of terpenes, which are mostly responsible for the typical rose scent. Buy comparing their expressions in roses with striking differences in scent characteristics, we were able to isolate some genes highly President of the association Les amis de la Roseraie du Val de Marne expressed in fragrant cultivars. These genes may represent key factors of the scent production.

The magical world of rose fragrances How to create a (Rose) perfume

Jacques Mouchotte Martin Gras

Roses’ perfume diversity is as wide as roses’ colors or flower shape. The perfumer has about 6,000 raw materials at his disposal, “naturals” Single roses have fans and quartered roses even more. and “synthetics”. The “synthetics” can be produced by analysing and Rosa Damascena fragrance is universally recognized as rose synthesizing the “naturals”. fragrance. It is because of the strong influence of perfume industry The creation of perfumes can take place in different ways: where Rose has a rather narrow meaning. Two species only are leading 1. By imitation: the perfumer works on a perfume as close as possible the market: damascena and centifolia. Roses essential oil, concrete to the odor of a rose, and absolute manufacturing methods are well known. 2. By variation: the perfumer reveals and underlines the various Modern Roses, after many generations of crosses and after many facets of a rose such as the spicy, fruity, woody, aromatic or citrus breeders’ generations, have incredible fragrances. The relationship notes, with Grasse’s perfume companies allowed a better fragrances 3.

Is this rose fragranced? A simple question, the answer is more sophisticated. In which conditions is the fragrance better exhaled?
