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.

The ultrastructure of proplastids in the leaves of five species of orchids was investigated: Paphiopedilum, Stanhopea, Cymbidium, Coelogyne and Orchis. The proplastids of the different species differ in the density of their stroma.

Evolutionary association of stomatal traits with leaf vein density in Paphiopedilum, Orchidaceae. [PDF]
Both leaf attributes and stomatal traits are linked to water economy in land plants. However, it is unclear whether these two components are associated evolutionarily.In characterizing the possible effect of phylogeny on leaf attributes and stomatal ...

In vitropropagation ofPaphiopedilumorchids
Paphiopedilum is one of the most popular and rare orchid genera. Members of the genus are sold and exhibited as pot plants and cut flowers. Wild populations of Paphiopedilum are under the threat of extinction due to over-collection and loss of suitable habitats. A reduction in their commercial value through large-scale propagation in vitro is an option

Plant genetic transformation: achievements, current status and future prospects
Summary Regeneration represents a fundamental biological process wherein an organism's tissues or organs repair and replace themselves following damage or environmental stress. In plant systems, injured tree branches can regenerate adventitious buds and develop new crowns through propagation techniques like cuttings and canopy pruning, while transgenic

ABSTRACT Corybas carsei is one of New Zealand's most endangered orchids, with a single remaining population in the Whangamarino Wetland (North Island). Although orchid mycorrhizae have proved a critical aspect of orchid conservation globally, until now mycorrhizal fungi of C. carsei have not been identified or utilised for conservation.

Knowledge gaps and opportunities for conservation with orchid collectors in Vietnam
Unsustainable harvesting of orchid species is a critical, global threat to orchid diversity and abundance, fueled by domestic and global demand. We found that knowledge about domestic and international regulations was low, and that orchid collectors were likely to believe that Vietnam has plenty of orchids left in the wild. Consequently, we suggest the

Abstract Due diligence is a fundamental component of ensuring a sustainable and legal wildlife trade that is also supportive of the livelihoods and businesses that depend on the trade. This is particularly true with species listed on the Convention on International Trade in Endangered Species (CITES) that are considered threatened or may become ...

Diverse geotropic responses in the orchid family
Abstract In epiphytes, aerial roots are important to combat water‐deficient, nutrient‐poor, and high‐irradiance microhabitats. However, whether aerial roots can respond to gravity and whether auxin plays a role in regulating aerial root development remain open‐ended questions.
