Generic and Subtribal Relationships in Neotropical Cymbidieae (Orchidaceae) Based on Matk/Ycf1 Plastid Data
LANKESTERIANA 13(3): 375—392. 2014. I N V I T E D P A P E R* GENERIC AND SUBTRIBAL RELATIONSHIPS IN NEOTROPICAL CYMBIDIEAE (ORCHIDACEAE) BASED ON MATK/YCF1 PLASTID DATA W. MARK WHITTEN1,2, KURT M. NEUBIG1 & N. H. WILLIAMS1 1Florida Museum of Natural History, University of Florida Gainesville, FL 32611-7800 USA 2Corresponding author: [email protected] ABSTRACT. Relationships among all subtribes of Neotropical Cymbidieae (Orchidaceae) were estimated using combined matK/ycf1 plastid sequence data for 289 taxa. The matrix was analyzed using RAxML. Bootstrap (BS) analyses yield 100% BS support for all subtribes except Stanhopeinae (87%). Generic relationships within subtribes are highly resolved and are generally congruent with those presented in previous studies and as summarized in Genera Orchidacearum. Relationships among subtribes are largely unresolved. The Szlachetko generic classification of Maxillariinae is not supported. A new combination is made for Maxillaria cacaoensis J.T.Atwood in Camaridium. KEY WORDS: Orchidaceae, Cymbidieae, Maxillariinae, matK, ycf1, phylogenetics, Camaridium, Maxillaria cacaoensis, Vargasiella Cymbidieae include many of the showiest align nrITS sequences across the entire tribe was Neotropical epiphytic orchids and an unparalleled unrealistic due to high levels of sequence divergence, diversity in floral rewards and pollination systems. and instead to concentrate our efforts on assembling Many researchers have posed questions such as a larger plastid data set based on two regions (matK “How many times and when has male euglossine and ycf1) that are among the most variable plastid bee pollination evolved?”(Ramírez et al. 2011), or exon regions and can be aligned with minimal “How many times have oil-reward flowers evolved?” ambiguity across broad taxonomic spans. -

Orchidaceae: Maxillariinae) Based on Combined Molecular Data Sets
LANKESTERIANA 13(1–2): 1—11. 2013 MOLECULAR PHYLOGENETICS OF MORMOLYCA (ORCHIDACEAE: MAXILLARIINAE) BASED ON COMBINED MOLECULAR DATA SETS RAFAEL ARÉVALO* & KENNETH M. CAMERON Department of Botany, University of Wisconsin-Madison, 430 Lincoln Drive, Madison, WI 53706-1381, U.S.A. *Author for correspondence: [email protected] ABSTRACT. The Neotropical orchid genus Mormolyca Fenzl, as currently circumscribed, encompasses a diverse group of ca. 27species. Many of these were included traditionally in Maxillaria sect. Rufescens, when similarity of floral morphology was considered foremost in their classification rather than the evolutionary history of the taxa. In order to begin revising species delimitation and clarifying the evolution and biology of the genus, we present a phylogenetic hypothesis using sequence data from five plastid loci (rpoC1, matK gene and flankingtrnK intron, atpB-rbcL intergenic spacer, and the 3’ portion of ycf1) and the nuclear ribosomal internal and external transcribed spacers (ITS, ETS). Resulting trees using both Bayesian and parsimony inference are congruent with each other, and generally well resolved. Based on current level of sampling across Maxillariinae, these molecular data support the monophyly of Mormolyca and shed light on the interspecific phylogenetic patterns within the genus. These include an early divergent paraphyletic grade of Mormolyca species successively sister to a clade with at least two definable subclades within. The latter are characterized by two different flower morphologies that are likely related to their pollination systems. Although not all relationships within the genus are fully resolved or supported, these results offer a first glimpse into the phylogeny of a small group of epiphytic orchids characterized by an unusually high level of variable vegetative characters, floral fragrance profiles, and pollination systems. -

Orchid Research Newsletter 75 (PDF)
Orchid Research Newsletter No. 75 January 2020 Editorial Orchids are perhaps not the first thing that comes to mind when we think about climate change. Record temperatures, catastrophic droughts, melting glaciers, out-of- control bush fires, burning rainforests and other calamities are of more immediate concern. But when we focus on orchid conservation, it is obvious that climate change looms large. It seems likely that orchids are more vulnerable to climate change than most other plant groups, for the following reasons: (1). Since about 70% of all orchids are epiphytes, they are probably more likely to be affected by drought. Even if mature plants would be able to survive unusually severe droughts, one can imagine that seedlings would be much more vulnerable. If such droughts become too frequent, seedling recruitment will be compromised, and the orchids will die out. (2). Since all orchids go through a mycoheterotrophic stage, at least as as seedlings, they depend on the presence of the right fungi for their long-term survival. It could be that climate change affects these fungi in such a way that they are no longer available to particular orchid species. These will then gradually disappear from their habitats. (3). Similarly, since many orchids depend on highly specific pollinators, the effect of climate change on the availability of these pollinators may be significant. A chain is only as strong as its weakest link, and we do not know if it is the orchid, the fungus or the pollinator that is the weakest link. (4). Orchids tend to occur in sparse, widely dispersed populations. -

MOLECULAR PHYLOGENETICS OF TRIBE EPIDENDREAE WITH EMPHASIS ON SUBTRIBE LAELIINAE (ORCHIDACEAE) A thesis submitted to the University of Reading for the degree of Doctor of Philosophy by Cássio van den Berg October 2000 Department of Botany, School of Plant Sciences, University of Reading and Jodrell Laboratory, Royal Botanic Gardens, Kew ABSTRACT In this project, the phylogenetic relationships of tribe Epidendreae, especially subtribe Laeliinae were assessed by using DNA sequence data. At the tribal level, I used data from three DNA regions, namely internal transcribed spacers of nuclear ribosomal DNA (ITS), and plastid matK (gene and spacers) and trnL-F (intron, exon and spacer). After individual and combined phylogenetic analysis using parsimony, it was possible to delimit Epidendreae as an exclusively Neotropical tribe (composed of subtribes Laeliinae, Pleurothallidinae, Ponerinae, Bletiinae and Chysinae). It is still unclear whether Coeliinae and Calypsoeae should be also included in Epidendreae. All Old World subtribes placed in Epidendreae in Dressler’s (1993) system belong to different tribes of subfamily Epidendroideae. The revised subtribe Bletiinae is composed only of Bletia, Hexalectris and Basiphyllaea. All Old World genera previously placed in Bletiinae belong also to Old World groups. Arpophyllum (previously Arpophyllinae) and Meiracyllium (previously Meiracyllinae) should be included in Laeliinae. Neocogniauxia and Dilomilis belong to a clade sister to Pleurothallidinae. Ponera, Isochilus and Helleriella (previously in the Scaphyglottis alliance within Laeliinae) belong to a recircumscribed version of Ponerinae, which is sister to Bletiinae. Two other datasets were collected to investigate in more detail phylogenetic relationships within Laeliinae. The first dataset used 295 ITS sequences to assess generic delimitation and species phylogenies. -

D.) Isolation and molecular characterization of 1-aminocyclopropane-1-carboxylate (ACC) oxidase gene in Cattleya spp. Miss Chanthra Timclub Abstract The plant hormone ethylene is known to stimulate a wide variety of plant response to flower senescence and fruit ripening. A gene in ethylene synthetic pathway, 1-aminocyclopropane-1-carboxylate (ACC) oxidase gene, was identified from flower of Cattleya spp. Lucky Strike variety. In this study, reverse transcription polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE) methods were used to amplify the ACC oxidase sequences. The cDNA of ACC oxidase (ACO) was cloned and characterized. The cDNA from Cattleya-ACOs, open reading frame (ORF) and 3’untranslated region (3’UTR), were 1,081 nucleotides in length. The sequence was further analysed by comparing with other ACC oxidase genes in GenBank Database. The results show that major difference between Cattleya spp. located at 3’UTR while the amino acid sequence alignment indicated high percent identity at 96.7%. In addition, the amino acid sequence of Cattleya-ACC oxidase was compared with 11 ACC oxidase genes of other plants from Genbank database. Ascorbate binding domains, ACC binding domain, ferrous ion binding domain, bicarbonate binding domain, leucine zipper and basic zipper domain were found in all ACOs. -
