Complete chloroplast genome of Oncidium Gower Ramsey and evaluation of molecular markers for identification and breeding in Oncidiinae [PDF]

open access: yesBMC Plant Biology, 2010
Background Oncidium spp. produce commercially important orchid cut flowers. However, they are amenable to intergeneric and inter-specific crossing making phylogenetic identification very difficult.

Phylogenetic endemism of the orchids of Megamexico reveals complementary areas for conservation [PDF]

open access: yesPlant Diversity, 2022
Orchid diversity provides a unique opportunity to further our understanding of biotic and abiotic factors linked to patterns of richness, endemism, and phylogenetic endemism in many regions. However, orchid diversity is consistently threatened by illegal

Convergent evolution of floral signals underlies the success of Neotropical orchids [PDF]

open access: yesProc Biol Sci, 2013
The great majority of plant species in the tropics require animals to achieve pollination, but the exact role of floral signals in attraction of animal pollinators is often debated.

From flower to fruit: The origin of the trilocular ovary and fruit development in Phragmipedium longifolium (Warsz. & Rchb.f.) Rolfe (Orchidaceae: Cypripedioideae). [PDF]

open access: yesPlant Biol (Stuttg)
Phragmipedium longifolium has a trilocular ovary with a post‐genital septum, and during fruit development, lignification plays a crucial role in facilitating dehiscence and seed dispersal. Abstract While carpels in Orchidaceae are predominantly unilocular, trilocular carpels can also occur, mainly in branches separated during the early diversification ...

Recent origin and rapid speciation of Neotropical orchids in the world's richest plant biodiversity hotspot. [PDF]

open access: yesNew Phytol, 2017
Summary The Andean mountains of South America are the most species‐rich biodiversity hotspot worldwide with c. 15% of the world's plant species, in only 1% of the world's land surface. Orchids are a key element of the Andean flora, and one of the most prominent components of the Neotropical epiphyte diversity, yet very little is known about their ...

Complete chloroplast genome sequence of an orchid model plant candidate: Erycina pusilla apply in tropical Oncidium breeding. [PDF]

open access: yesPLoS ONE, 2012
Oncidium is an important ornamental plant but the study of its functional genomics is difficult. Erycina pusilla is a fast-growing Oncidiinae species. Several characteristics including low chromosome number, small genome size, short growth period, and ...

Life History Evolution and Genome Size in Subtribe Oncidiinae (Orchidaceae) [PDF]

open access: yesAnnals of Botany, 2005
Within Oncidiinae, there are several groups of species that are effectively annuals, and we wished to see if these species had smaller genome sizes than average for the subtribe.Fifty-four genome size estimates (50 of which are new) for species in subtribe Oncidiinae (Orchidaceae) were examined for the first time in a phylogenetic context to evaluate ...
