Please send any nominations to me, in writing, with consent of nominee to serve if elected, by mid February. DAVID PEARMAN (Hon. Gen. Sec.) Algiers, Feock, Truro, Cornwall, TR3 6RA FROM THE PRESIDENT I hope you had a good Christmas, but the New Year is now upon us and, at last, after many months of negotiations with prospective funders, a BSBI Development Officer has been appointed. Dr. Gabriel Hemery will be taking up his post at the end of February with the task of enabling the Society to meet the changing and ever-increasing demands of the future. BSBI has relied in the past mainly upon the services of a few volunteer officers but in spite of their dedication and proven competence, in recent years has outgrown its capacity to develop in this ever more challenging environment. The Society is rather late in following in the footsteps of some other similar societies which, in taking this major step, have never looked back and I hope that the future of BSBI will now be assured by being able to keep abreast of the pace of change. BSBI in the plant world has often been likened to the British Trust for Ornithology as the corre­ sponding body in the bird world, in providing reliable and accurate data for many purposes, not least of which are inputs into wildlife legislation and Biodiversity Action Planning, as well as the distributional and phytogeographical infonnation for which it is more usually associated. Whereas BSBI has been largely self-funding or in receipt of limited grants only for specific projects, the BTO has been able to develop over the years by tapping into major funding sources. In the future I hope that the BSBI might also draw on these resources and the appointment of our first permanent staff member will rncilitate this ambition. Gabriel comes to us from the Northmoor Trust for Countryside Conservation having developed and managed their broad-leaved forestry research centre. He also has considerable experience in working collaboratively with partners, managing multi-disciplinary teams, strategic planning and developing business plans. Most of you will have your first chance of meeting Gabriel at the BSBI AGM at Ferryside, Car­ marthenshire, in May. I hope that he will be able outline how he intends to implement the BSBI's development priorities over the next year or two. I, and I am sure, you too, welcome him to his new post and will assist him in every way possible in shaping the Society's future and wish him success. Also at the AGM, Bob Ellis will be able to update us on progress with Local Change. I hope that, by now, all field records have been sent to him as I know that he intends to start data processing in earnest in January. Bob has been very encouraged by the very high proportion of data that has been sent electronically, a great step forward from the majority of records received for input during the New Atlas scheme. This will allow him welcome additional time for analysis of the data and the production of the final report. A booking form for the Ferryside AGM is included in this mailing, together with BSBI Year Book 2005 detailing the wide range of other BSBI meetings which should be attractive to all members as they cater for varying degrees of botanical expertise. I look forward to seeing you during the season.

It is IMPORTANT that all articles for publication in News be sent to Leander at his new address which can be found inside the front cover. During his move from Liverpool Museum to Manchester Museum most correspondence was forwarded to him but a glitch with emails resulted in some sent to him at Liverpool during the last 2 weeks of November and the first two weeks of December being lost rather than forwarded. If anyone sent an email during those dates and has not received a reply would they please accept his apologies and send the message again to: [email protected] Congratulations to Peter Benoit our vice-county recorder for Merioneth (v.c. 48) who has now been in post for 50 years, our longest serving vice-county recorder. Correction to BSBI News 97 Colour Plate 3 The photograph numbers 1-7 and captions illustrating the life history of Primula farinosa were unfortunately 'shuffled' by the General Editor and therefore present a somewhat garbled picture to the possible puzzlement of readers. The author David Hambler, to whom profuse apologies are due, has provided the following brief replacement captions, each incorporating a date: Plate 3 top row: (1) Dormant, 15 March. (2) Early vegetative, 9 May. (3) Late vegetative, 3 September. (4) Flowering, 5 June. Plate 3 bottom row: (5) Post flowering (Beginning of fruiting), 7 July. (6) Fruiting, 19 September.

  • The Evolution of Gene and Genome Duplication in Soybean
    THE EVOLUTION OF GENE AND GENOME DUPLICATION IN SOYBEAN by BRIAN D. NADON (Under the Direction of Scott A. Jackson) ABSTRACT Duplication of DNA is one of the prime drivers of diversification, speciation, and adaptation for life on earth. Plants are highly tolerant of polyploidy or whole-genome duplication (WGD) - indeed, all characterized plant genomes show traces of a history of polyploidy. Duplicated genes often diverge in their function post-duplication, and can assume subsets of their old functions, take on new functions, or be deleted altogether. Studying how these processes have affected crop plants can illuminate their evolution and show how they might be improved through breeding in the future. Legumes, and especially soybean (Glycine max L.), offer a valuable system to study this. For this work, first, the soybean genome was aligned to itself, which showed that gene pairs from the most recent duplication event in soybean have maintained similar expression profiles within tissues and have maintained their methylation status more consistently than older duplicate pairs. Next, an algorithm (TetrAssign) was developed to reconstruct and phase ancient soybean subgenomes post-WGD, and comparison of these reconstructions with maize showed that soybean’s ancient subgenome sets were less divergent in their gene deletion, expression, and methylation profiles than maize’s. Then, a set of gene families (orthogroups) for soybean and several other sequenced legume genomes was analyzed to reveal that rates of stochastic gene duplication were low, while gene deletion (death) rates were higher but variable among the legume branches, and furthermore found that the Glycine-specific duplication event had a much higher retention of gene duplicates post-WGD than the Faboideae duplication.

Vol. LX, 2016 Print ISSN 2285-5653, CD-ROM ISSN 2285-5661, Online ISSN 2286-1580, ISSN-L 2285-5653 OVERVİEW OF DAHLIA BREEDING Akife DALDA ŞEKERCİ1, Osman GÜLŞEN1 1 Erciyes University, Department of Horticulture, Kayseri, Turkey Corresponding author email: [email protected] Abstract Dahlias are popular ornamental plants cultivated in many countries. It is an important garden plant owing to its diversity in colours, size, shapes, forms and profusion of flowering. Dahlia,member of the Asteraceae family. This review describes and compares the conventional and molecular genetics methods being used for breeding. Dahlia is vegetatively propagated with tubers commonly. Breeding programmes have focussed on improving various characteristics to enhance ornamental values, including flower colour, size and form, and production quality. Although desirable traits have been introduced by classical breeding, there are limitations to this technique. Firstly, distant crosses may be limited by incompatibility or differences in ploidy level that is very common in dahlias. Secondly, characteristics such as uniform growth and synchronous flowering are polygenic. Thirdly, several viruses are known to infect dahlia. The dahlia breeding and its methods are described and discussed in this review. Alternative breeding methods will provide faster procedures. In the past, classical breeding approaches like introduction, hybridization, composite crossing, multiline, and backcross breeding were utilized for this purpose. However, each of these methods has advantages and disadvantages. Recent developments in plant biotechnology such as directed mutation, genomics and recombinant DNA technology were adapted by breeders to develop more improved cultivars of dahlias. Key words: Ornamental plant, landscape, Asteraceae, mutation breeding, hybridization.

The evolution of chromosome size, structure and shape, number, and the change in DNA composition suggest the high plasticity of nuclear genomes at the chromosomal level. Repetitive DNA sequences, which represent a conspicuous fraction of every eukaryotic genome, particularly in plants, are found to be tightly linked with plant chromosome evolution. Different classes of repetitive sequences have distinct distribution patterns on the chromosomes. Mounting evidence shows that repetitive sequences may play multiple generative roles in shaping the chromosome karyotypes in plants. Furthermore, recent development in our understanding of the repetitive sequences and plant chromosome evolution has elucidated the involvement of a spectrum of epigenetic modification. In this review, we focused on the recent evidence relating to the distribution pattern of repetitive sequences in plant chromosomes and highlighted their potential relevance to chromosome evolution in plants. We also discussed the possible connections between evolution and epigenetic alterations in chromosome structure and repatterning, such as heterochromatin formation, centromere function, and epigenetic-associated transposable element inactivation.
