The evolution of sexual signaling is linked to odorant receptor tuning in perfume-collecting orchid bees

open access: yesNature Communications, 2020
Sexual signaling is an important reproductive barrier known to evolve early during the formation of new species, but the genetic mechanisms that facilitate the divergence of sexual signals remain elusive.

The complete chloroplast genome of an endangered species Cymbidium mastersii (Orchidaceae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
Cymbidium mastersii Griff. & Lindl. is an endangered orchid. In this study, we report the complete chloroplast (cp) genome sequence and the cp genome features of C. mastersii. The cp genome sequence of C. mastersii was 155,362 bp in length.

Lack of S-RNase-Based Gametophytic Self-Incompatibility in Orchids Suggests That This System Evolved after the Monocot-Eudicot Split

open access: yesFrontiers in Plant Science, 2017
Self-incompatibility (SI) is found in approximately 40% of flowering plant species and at least 100 families. Although orchids belong to the largest angiosperm family, only 10% of orchid species present SI and have gametophytic SI (GSI).

Molecular Evolution of Chloroplast Genomes of Orchid Species: Insights into Phylogenetic Relationship and Adaptive Evolution

open access: yesInternational Journal of Molecular Sciences, 2018
Orchidaceae is the 3rd largest family of angiosperms, an evolved young branch of monocotyledons. This family contains a number of economically-important horticulture and flowering plants.

Modelling sexually deceptive orchid species distributions under future climates: the importance of plant–pollinator interactions

open access: yesScientific Reports, 2020
Biotic interactions play an important role in species distribution models, whose ignorance may cause an overestimation of species' potential distributions.

Pollination Mechanisms are Driving Orchid Distribution in Space

open access: yesScientific Reports, 2020
Understanding the abundance and distribution patterns of species at large spatial scales is one of the goals of biogeography and macroecology, as it helps researchers and authorities in designing conservation measures for endangered species. Orchids, one

Orchid conservation: how can we meet the challenges in the twenty-first century?

open access: yesBotanical Studies, 2018
With c. 28,000 species, orchids are one of the largest families of flowering plants, and they are also one of the most threatened, in part due to their complex life history strategies.
