The Complete Plastome Sequences of Four Orchid Species: Insights into the Evolution of the Orchidaceae and the Utility of Plastomic Mutational Hotspots

Frontiers in Plant Science, 2017
Orchidaceae (orchids) is the largest family in the monocots, including about 25,000 species in 880 genera and five subfamilies. Many orchids are highly valued for their beautiful and long-lasting flowers. However, the phylogenetic relationships among the

What are the consequences of water stress on the development of late postzygotic reproductive isolation in an orchid hybrid zone?

Plant Species Biology, EarlyView.
Hybrids vulnerable to drought may increase postzygotic isolation in hybrid zones. Drought experiments can reveal the influence of climate change on hybrid zones. Crassulacean acid metabolism in parental species and hybrids was negatively affected by drought.

Phylotranscriptomic analysis and genome evolution of the Cypripedioideae (Orchidaceae).

American-Eurasian journal of botany, 2018
PREMISE OF THE STUDY The slipper orchids (Cypripedioideae) are a morphologically distinct subfamily of Orchidaceae. They also have some of the largest genomes in the orchids, which may be due to polyploidy or some other mechanism of genome evolution.

Next-generation sequencing yields the complete chloroplast genome of Pleione chunii, a vulnerable orchid in China

Mitochondrial DNA. Part B. Resources, 2019
Pleione chunii is a vulnerable epiphytic orchid with significant ornamental value. Here, we report the first complete chloroplast genome of P. chunii. The circular genome was 158,880 bp in length and consisted of a pair of inverted repeats (IR 26,465 bp),

The stepwise rise of angiosperm‐dominated terrestrial ecosystems

Biological Reviews, EarlyView.
ABSTRACT Angiosperms are the most diverse and abundant plant taxon today and dominate the majority of Earth's terrestrial ecosystems. They underwent rapid divergence and biogeographic expansion from the early to the middle Cretaceous. Yet, transformative ecosystem change brought about by the increased ecological dominance of angiosperms unfolded ...

Phylogenetics of subtribe Orchidinae s.l. (Orchidaceae; Orchidoideae) based on seven markers (plastid matK, psaB, rbcL, trnL-F, trnH-psba, and nuclear nrITS, Xdh): implications for generic delimitation

BMC Plant Biology, 2017
Subtribe Orchidinae (Orchidaceae, Orchidoideae) are a nearly cosmopolitan taxon of terrestrial orchids, comprising about 1800 species in 47 to 60 genera.

Endocarpic trichomes in Vandeae (Orchidaceae)

Flora, 2021
Endocarpic trichomes have been analyzed in fruits of 267 species from 80 genera of the orchid tribe Vandeae, using light and scanning electron microscopy. They have been observed for the first time in 56 genera and confirmed in the rest. The present study describes their microstructure in Vandeae and suggests a standardization for its terminology ...
