Florian Wagner iv Abstract Plant systematics, the study of taxonomy, phylogeny and evolutionary processes in plants has undergone considerable progress in the last decades. The application of modern molecular approaches and DNA-sequencing techniques in the field has led to an improved inventory of biodiversity and a better understanding of evolutionary processes shaping the biological diversity on our planet. The increased availability of molecular and genomic data has particularly facilitated the investigation of shallowly diverged and taxonomically complex taxon-groups, which is challenging due to minor morphological differences, low genetic differentiation and/or hybridization among taxa. The present thesis investigates species delimitation, hybridization and polyploidization in the recently diverged genera Leucanthemum Mill. and Rhodanthemum B.H. Wilcox & al. of the subtribe Leucantheminae K.Bremer & Humphries (Compositae, Anthemideae) by applying Sanger-, 454-pyro-, and restriction site associated -

A Revision of Ornithoboea (Gesneriaceae)
Gardens’ Bulletin Singapore 66(1): 73–119. 2014 73 A revision of Ornithoboea (Gesneriaceae) S.M. Scott1 & D.J. Middleton2 1Royal Botanic Garden Edinburgh, 20A Inverleith Row, Edinburgh EH3 5LR, Scotland [email protected] 2Herbarium, Singapore Botanic Gardens, National Parks Board, 1 Cluny Road, Singapore 259569 [email protected] ABSTRACT. The genus Ornithoboea C.B.Clarke (Gesneriaceae) from limestone habitats in Peninsular Malaysia, Thailand, Myanmar (Burma), Laos, Vietnam and Southern China is revised. It has 16 species, three of which are newly described: Ornithoboea maxwellii S.M.Scott from Thailand, Ornithoboea puglisiae S.M.Scott from Thailand and Ornithoboea obovata S.M.Scott from Vietnam. The plants are characterised by small, bilabiate flowers with a distinctive palatal beard on the lower lobes and a circlet of hairs around the mouth of the corolla tube. A key is provided, all species are described, and distribution maps and IUCN conservation assessments are given for all species. Keywords. Karst limestone, Ornithoboea, taxonomic revision Introduction The genus Ornithoboea C.B.Clarke (Gesneriaceae) consists of a group of herbaceous plants on karst limestone from Peninsular Malaysia, Thailand, Myanmar (Burma), Laos, Vietnam and Southern China, its most northerly occurrence. No species have yet been recorded from Cambodia. Ornithoboea was first described by Clarke (1883) from a specimen sent to him by the Rev. C. Parish from his collections in Burma. The specimen was accompanied by a drawing and analysis by Parish who commented on its resemblance to Boea except for the corolla and broader submembranous capsule. Clarke (1883) also compared it to Boea but stated that the capsule valves are more twisted, a comment that was probably why three more Ornithoboea species published soon thereafter, all of Chinese origin, were included in Boea rather than Ornithoboea. -
Expression Shifts of Floral Symmetry Genes Correlate to Flower Actinomorphy in East Asia Endemic Conandron Ramondioides (Gesneri
Hsin and Wang Bot Stud (2018) 59:24 https://doi.org/10.1186/s40529-018-0242-x ORIGINAL ARTICLE Open Access Expression shifts of foral symmetry genes correlate to fower actinomorphy in East Asia endemic Conandron ramondioides (Gesneriaceae) Kuan‑Ting Hsin1 and Chun‑Neng Wang1,2* Abstract Background: Bilateral symmetry fower (zygomorphy) is the ancestral state for Gesneriaceae species. Yet independ‑ ent reversions to actinomorphy have been parallelly evolved in several lineages. Conandron ramondioides is a natural radially symmetrical species survived in dense shade mountainous habitats where specialist pollinators are scarce. Whether the mutations in foral symmetry genes such as CYC, RAD and DIV genes, or their expression pattern shifts contribute to the reversion to actinomorphy in C. ramondioides thus facilitating shifts to generalist pollinators remain to be investigated. To address this, we isolated putative orthologues of these genes and relate their expressions to developmental stages of fower actinomorphy. Results: Tissue specifc RT-PCR found no dorsal identity genes CrCYCs and CrRADs expression in petal and stamen whorls, while the ventral identity gene CrDIV was expressed in all petals. Thus, ventralized actinomorphy is evolved in C. ramondioides. However, CrCYCs still persists their expression in sepal whorl. This is congruent with previous fndings that CYC expression in sepals is an ancestral state common to both actinomorphic and zygomorphic core Eudicot species. Conclusions: The loss of dorsal identity genes CrCYCs and CrRADs expression in petal and stamen whorl without mutating these genes specifes that a novel regulation change, possibly on cis-elements of these genes, has evolved to switch zygomorphy to actinomorphy. -
Agrobacterium – Mediated Genetic Transformation of the Resurrection Plant Haberlea Rhodopensis Friv
10 Bulgarian Journal of Agricultural Science, 19 (2) 2013, 10–14 Agricultural Academy AGROBACTERIUM – MEDIATED GENETIC TRANSFORMATION OF THE RESURRECTION PLANT HABERLEA RHODOPENSIS FRIV. G. PETROVA* and D. DJILIANOV AgroBioInstitute, BG – 1164 Sofi a, Bulgaria Abstract PETROVA, G. and D. DJILIANOV, 2013. Agrobacterium – mediated genetic transformation of the resurrection plant Haber- lea rhodopensis Friv. Bulg. J. Agric. Sci., Supplement 2, 19: 10–14 Resurrection plants are widely used models for desiccation tolerance studies. Several genes have been successfully iso- lated from these species. In an attempt to study their role, these genes have been successfully transferred in other model plants. Since resurrection plants are as a rule, polyploids, they are pure targets for mutational studies. In this respect, the establish- ment of effi cient and repeatable transformation system will contribute signifi cantly for the elucidation of stress tolerance. In this study we describe for the fi rst time, a procedure for Agrobacterium tumefaciens – mediated genetic transformation of the resurrection plant Haberlea rhodopensis Friv. For in vitro regeneration of Haberlea, we used liquid WPM media. It enables us to achieve direct regeneration and transformation system, which is an alternative to the callus-based transformation, used in other resurrection plants. The A. tumefaciens strain LBA4404 harbouring the plasmid pCAMBIA 1305.1 which contains the gus gene as a reporter gene and hpt II gene as a selectable marker gene was used. The initial experiments were conducted in order to establish the suitable concentration of cefotaxime for the elimination of Agrobacterium from cultures, as well as the optimal concentration of hygromycin for the selection of transformed plants. -

The Evolution of Vegetative Desiccation Tolerance in Land Plants
Plant Ecology 151: 85–100, 2000. 85 © 2000 Kluwer Academic Publishers. Printed in the Netherlands. The evolution of vegetative desiccation tolerance in land plants Melvin J. Oliver1,Zoltan´ Tuba2 &BrentD.Mishler3 1Plant Stress and Water Conservation Laboratory, United States Department of Agriculture, Agricultural Research Service, Lubbock TX, USA (E-mail: [email protected]); 2Department of Botany and Plant Physiol- ogy, University of Agricultural Sciences, Gödöllõ, Hungary; 3University Herbarium, Jepson Herbarium, and Department of Integrative Biology, University of California, Berkeley, CA, USA Abstract Vegetative desiccation tolerance is a widespread but uncommon occurrence in the plant kingdom generally. The majority of vegetative desiccation-tolerant plants are found in the less complex clades that constitute the algae, lichens and bryophytes. However, within the larger and more complex groups of vascular land plants there are some 60 to 70 species of ferns and fern allies, and approximately 60 species of angiosperms that exhibit some degree of vegetative desiccation tolerance. In this report we analyze the evidence for the differing mechanisms of desiccation tolerance in different plants, including differences in cellular protection and cellular repair, and couple this evidence with a phylogenetic framework to generate a working hypothesis as to the evolution of desiccation tolerance in land plants. We hypothesize that the initial evolution of vegetative desiccation tolerance was a crucial step in the colonization of the land by primitive plants from an origin in fresh water. The primitive mechanism of tolerance probably involved constitutive cellular protection coupled with active cellular repair, similar to that described for modern-day desiccation-tolerant bryophytes. As plant species evolved, vegetative desiccation toler- ance was lost as increased growth rates, structural and morphological complexity, and mechanisms that conserve water within the plant and maintain efficient carbon fixation were selected for. -
