Mycorrhizal communities of Vanilla planifolia in an introduction area (La Réunion) under varying cultivation practices

open access: yesPLANTS, PEOPLE, PLANET, Volume 6, Issue 3, Page 683-696, May 2024.
Vanilla is one of the most valuable spices in the world. In Madagascar and La Réunion, the world's leading producers, vanilla is of great economic and cultural importance. Like all orchids, vanilla plants associate with mycorrhizal fungi in their roots forming mutualistic associations that allow them to grow and thrive.

Turnover importance: Operationalizing beta diversity to quantify the generalism continuum

open access: yesMethods in Ecology and Evolution, Volume 15, Issue 5, Page 951-964, May 2024.
Abstract Generalization is difficult to quantify, and many classifications exist. A beta diversity framework can be used to establish a numeric measure of generalist tendencies that jointly describes many important features of species interactions, namely spatiotemporal heterogeneity.

Comparative anatomy of elaiophores and oil secretion in the genus Gomesa (Orchidaceae) [PDF]

open access: yes, 2013
Oils are atypical floral rewards in Orchidaceae, and are produced by epidermal glands called elaiophores. Flowers of many members of the sub-tribe Oncidiinae either produce oil or mimic oil-producing flowers of Malpighiaceae.

The origin and speciation of orchids

open access: yesNew Phytologist, Volume 242, Issue 2, Page 700-716, April 2024.
Summary Orchids constitute one of the most spectacular radiations of flowering plants. However, their origin, spread across the globe, and hotspots of speciation remain uncertain due to the lack of an up‐to‐date phylogeographic analysis. We present a new Orchidaceae phylogeny based on combined high‐throughput and Sanger sequencing data, covering all ...
