DOI: 10.1002/ajb2.16084
Abstract: PREMISE Pogoniopsis likely represents an independent photosynthesis loss in orchids. We use phylogenomic data to better identify the phylogenetic placement of this fully mycoheterotrophic taxon, and investigate its molecular evolution. METHODS We performed likelihood analysis… read more here.

DOI: 10.1007/s10265-020-01205-z
Abstract: The very high floral diversity of Orchidaceae has often been attributed to the intricate relationships between orchids and their pollinators. In particular, the interaction between long-spurred orchids and hawkmoths has been well-studied. However, several recent… read more here.

DOI: 10.1093/aob/mcaa132
Abstract: BACKGROUND AND AIMS The temporal dimensions of floral adaptation to pollinators are not yet well understood, partly because we lack accurate information on the diel rhythms of flower visitation for many pollinators. We investigated whether… read more here.

DOI: 10.1093/aob/mcac140
Abstract: BACKGROUND AND AIMS Trap flowers are fascinating cases of adaptation, often linked to oviposition site mimicry systems. Some trap flowers do not imprison pollinators for a pre-determined period, but rather force them to move through… read more here.

Partial mycoheterotrophy in Apostasia wallichii, an early‐diverging Asian tropical orchid
Sign Up to like & getrecommendations! Published in 2025 at "Plant Biology"
DOI: 10.1111/plb.70004
Abstract: All orchids exhibit mycoheterotrophy during their early development stages, which predisposes certain species to retain this nutritional mode into adulthood. Consequently, many orchids adopt partial mycoheterotrophy, a mixotrophic strategy combining carbon acquisition through both autotrophy… read more here.
