The Orchidaceae family comprises a highly diverse group of flowering plants. The genus Cattleya is restricted to the Neotropics, with approximately 80 % of the species present in Brazil occurring in epiphytic, rupicolous, and terrestrial habitats. During surveys that aimed to investigate root fungal endophytes of two native orchids, C. locatellii a...
Anoectochilus brevilabris and similar species have been much confused. Three former synonyms, A. griffithii, A. tridentatus and A. chapaensis, are here reinstated. Anoectochilus dulongensis and A. annamensis are treated as new synonyms of A. brevilabris and A. baotingensis respectively. The duplicate of the lectotypes of A. chapaensis belongs to A....

Understanding plant reproductive strategies is vital for conserving endangered species. This study reveals a novel self‐pollination mechanism in the diminutive orchid Stigmatodactylus sikokianus, facilitated by the movement of a finger‐like appendage beneath the stigma. While this less‐than‐1‐mm‐long structure inspired the...
This study aimed to determine the dynamics of dormancy using triphenyl tetrazolium chloride (TTC) and asymbiotic germination in Laelia speciosa (Kunth) Schltr. seeds stored for three years and one year at different temperatures. This is the first report of a circannual rhythm in L. speciosa seeds under controlled storage conditions. Two experiments...
Detailed knowledge of reproductive traits and success is essential for the effective conservation of rare and endangered species. It has been reported that Cephalanthera longifolia and C. rubra (Orchidaceae) were abundantly fruiting in some regions several decades ago, but recent studies have shown a low natural fruit set rate for both species. The...

Seed morphometric analysis of Orchidaceae is carried out from the past years in world. As seed diversity in Orchidaceae is very minute with many ornamentations variation. Present work discuses about 106 SEM photographs of diversified orchids in North Karnataka with its parameters.
Plant regulators are studied because they can alter commercially significant aspects of plant growth. Gibberellic acid (GA3) exemplifies this, as it plays a crucial role in the growth and flowering processes of various vegetables. Thus, the present study sought to verify the effects caused by the exogenous application of different doses of the plan...

β-glucosidases (BGLUs) are abundant enzymes in plants that play pivotal roles in cell wall modification, hormone signal transduction, secondary metabolism, defense against herbivores, and volatile compound release. Bletilla striata, a perennial herb revered for its therapeutic properties, lacks a comprehensive analysis of its BGLU gene family despi...
Orchid mycorrhizal fungi (OMF) associations in the Orchidaceae are thought to have been a major driver of diversification in the family. In the terrestrial orchid tribe Diurideae, it has long been hypothesised that OMF symbiont associations may reflect evolutionary relationships among orchid hosts. Given that recent phylogenomic efforts have been u...
Introduction
Gastrodiae Rhizoma (referred to Tianma in Chinese), the dried tuber of Gastrodia elata Bl. (Orchidaceae), is utilized as a medicine-food homology product. Sulfur fumigation is commonly employed in the processing of Gastrodiae Rhizoma (GR). Polysaccharides are a crucial active substance produced in GR, yet the impacts of sulfur fumigati...
