Rapid evolution of chemosensory receptor genes in a pair of sibling species of orchid bees (Apidae: Euglossini). [PDF]

open access: yes, 2015
BackgroundInsects rely more on chemical signals (semiochemicals) than on any other sensory modality to find, identify, and choose mates. In most insects, pheromone production is typically regulated through biosynthetic pathways, whereas pheromone sensory

Nectar and oleiferous trichomes as floral attractants in Bulbophyllum saltatorium Lindl. (Orchidaceae) [PDF]

open access: yes, 2017
Although many Orchidaceae have deceit flowers that produce no reward, the most common reward, when present, is nectar. Bulbophyllum, however, is unusual in that the labellar secretions of most species investigated to date lack sugars, and, therefore ...

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).

Expanding the horizons of embryo screening: performance and case studies of preimplantation genetic testing via whole genome sequencing

open access: yesAcademia Molecular Biology and Genomics
Conventional preimplantation genetic testing for aneuploidy (PGT-A) and for monogenic disorders (PGT-M) is very limited in scope. These methods typically assess chromosomal ploidy or target only one or two specific variants carried by the ...
