Abstract Background: Orchids constitute one of the most diverse group of plants, they provide a large number of benefits to human society. Questions: What are the ecosystem services provided by orchids? Data description: We performed a systematic review based on 413 articles, of which 224 provide relevant information, focusing on publications by ec...
Cette présentation offre une exploration des différents aspects botaniques de la vanille. En plus d'aborder la taxonomie, la structure de la plante et les techniques de reproduction, nous examinerons également la répartition géographique de la vanille, mettant en lumière les variations régionales et leur influence sur sa culture. La présentation in...

The Orchidaceae is a mega-diverse plant family with ca. 29,000 species with a large variety of life forms that can colonize transitory habitats. Despite this diversity, little is known about their flowering integrators in response to specific environmental factors. During the reproductive transition in flowering plants a vegetative apical meristem ...

The hyperdiverse orchid genus Bulbophyllum is the second largest genus of flowering plants and exhibits a pantropical distribution with a center of diversity in tropical Asia. The only Bulbophyllum section with a center of diversity in Australasia is sect. Adelopetalum. However, the phylogenetic placement, interspecific relationships, and spatio-te...

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 five s...
The world-renowned pollination system of the long-spurred orchid Angraecum sesquipedale Thouars and the long-tongued hawkmoth Xanthopan praedicta (Rothschild & Jordan, 1903), from Madagascar, is the best-known example of the predictive power of evolutionary ecology1,2, yet its actual degree of specialisation remains poorly described due to the inco...

Black rot is a common disease of Gastrodia elata, causing serious threats to G. elata production. In this study, a total of 17 Cylindrocarpon-like strains were isolated from G. elata black rot tissues. Multilocus sequence analyses based on ITS, HIS, TEF, and TUB combined with morphological characterizations were performed to identify six Ilyonectri...

Gastrodia elata Blume, a fully mycoheterotrophic perennial plant of the family Orchidaceae, is a traditional Chinese herb with medicinal and edible value. Interestingly, G. elata requires symbiotic relationships with Mycena and Armillaria strains for seed germination and plant growth, respectively. However, there is no comprehensive summary of the ...

Aim: Species with disjunct geographic distributions provide natural opportunities to investigate incipient or recent allopatric divergence. The combination of both genetic and ecological data may be fruitful to decipher the causes of such pattern: i) actual vicariance, ii) successful colonization from one source range to a new range (dispersal, bio...
