<strong>Abstract</strong><strong>—</strong> Orchids (Orchidaceae) are a diverse plant family known for their unique nutritional adaptations, allowing them to thrive in a variety of ecosystems. This five-year study explores the intricate nutrient acquisition strategies of orchids in the Western Ghats, particularly in the Wayanad region, a biodiversity hotspot with a rich diversity of epiphytic and terrestrial orchid species. The research investigates five primary nutritional pathways: mycorrhizal symbiosis, atmospheric nutrient absorption, rainwater uptake, organic matter decomposition, a

Abstract:

Worldwide scientific publications on the remarkably diverse Orchidaceae family are comprehensive, but Africa's craze for the taxon was only felt a few decades ago. This largest and threatened family of flowering plants is widely distributed in tropical areas and recognized by several authors for its environmental, ornamental, and medicinal importance. This review aims to identify research patterns on African orchids using co-citation analysis and bibliometric information visualization. 386 publications concerning African orchids listed in the Scopus database from 1968 to May 2020 were recorded

Fungal symbionts involved in mycorrhizal associations are known to vary considerably in both specificity and the level of benefits conferred on their plant hosts.

Neotropical orchids are vulnerable to extinction due to overharvesting, habitat destruction and climate change. However, a basic understanding of orchid seed biology to support conservation efforts is still lacking for most species. Seed morphology is linked to plant adaptation and evolution, influencing seed dispersal, dormancy, longevity, and germination, which are valuable traits for conservation. In this study, we characterized and compared the morphological traits of seed capsules (size, shape, and colour) and seeds (seed and embryo shape and size and internal airspace volume) for three e

This is the reason for its use in developing many crops of economic interest, as is the case of orchids in the flower market. Polyploidy in ornamental plants is mainly associated wi

Adaptations are specialized mechanisms that permit a plant or animal to live in a particular area or habitat. Adaptational mechanisms in plant morphology are essential for the transition to an epiphytic canopy habitat. Orchids have specific adaptational mechanisms in the roots, stems, leaves, flowers, seed and other physiological processes.

Danxiaorchis yangii is a fully mycoheterotrophic orchid that lacks both leaves and roots, belonging to the genus Danxiaorchis in the subtribe Calypsoinae. In this study, we assembled and annotated its mitochondrial genome (397,867 bp, GC content: 42.70%), identifying 55 genes, including 37 protein-coding genes (PCGs), 16 tRNAs, and 2 rRNAs, and conducted analyses of relative synonymous codon usage (RSCU), repeat sequences, horizontal gene transfers (HGTs), and gene selective pressure (dN/dS). Additionally, we sequenced and assembled its plastome, which has a reduced size of 110,364 bp (GC cont

Spatial management consists of land property and land use management, both on land and in the ocean. From the perspective of ‘social-ecological systems’, local spatial management represented the resilience of adaptation that indigenous knowledge and environment change were interrelated. This study aims to extract critical components that contribute to the dynamic maintenance of the stability and sustainability of local spatial management. The indigenous knowledge of Yami people on Orchid Island was investigated as a case study to highlight how indigenous institutions functioned in a more suita

Abstract:

Epiphytes are a characteristic component of tropical rainforests. Out of the 25 000 orchid species currently known to science, more than 70% live in tree canopies. Understanding when and how these orchids diversified is vital to understanding the history of epiphytic biomes. We investigated whether orchids managed to radiate so explosively owing to their predominantly epiphytic habit and/or their specialized pollinator systems by testing these hypotheses from a statistical and phylogenetic standpoint. For the first approach, species numbers of 100 randomly chosen epiphytic and terrestrial gene

Abstract:

Abstract Crassulacean acid metabolism (CAM) is a major adaptation of photosynthesis that involves temporally separated phases of CO2 fixation and accumulation of organic acids at night, followed by decarboxylation and refixation of CO2 by the classical C3 pathway during the day. Transitory reserves such as soluble sugars or starch are degraded at night to provide the phosphoenolpyruvate (PEP) and energy needed for initial carboxylation by PEP carboxylase. The primary photosynthetic pathways in CAM species are well known, but their integration with other pathways of central C metabolism during

Abstract:

Abstract Background and Aims The geographical distribution of plant species is linked fundamentally not only to environmental variables, but also to key traits that affect the dispersal, establishment and evolutionary potential of a species. One of the key plant traits that can be expected to affect standing genetic variation, speed of adaptation and the capacity to colonize and establish in new habitats, and therefore niche breadth and range size, is the plant mating system. However, the precise role of the mating system in shaping range size and niche breadth of plant species remains unclear

Abstract:

The pantropical genus Vanilla is a member of the Orchidaceae family, one of the largest and most diverse families of angiosperms in the world. It originated in America and differentiated in America, Africa, and Asia. About 132 species of Vanilla have now been accepted since the discovery of the genus. Within the Vanilla genus, leaflessness has appeared at least three independent times, in Africa, Asia, and America as an adaptation to drought conditions. The South-West Indian Ocean (SWIO) region, a biodiversity hotspot for orchids, is home to seven leafless species. Chloroplast markers failed t

Abstract:

The leaf surface micromorphology of Cattleya gaskelliana juvenile plants, propagated in vitrofrom seeds, as well as of adult plants, cultivated in glasshouse, was analyzed by scanning electron microscopy (SEM). The leaves of both juvenile and adult plants are hypostomatic, their stomata are of tetracytic type. It was found that development of single stomata on the adaxial leaf surface of juvenile plants was induced by in vitro conditions. During the acclimation of in vitro propagated plants to glasshouse conditions the following changes of leaf surface micromorphology have been observed: 1) co
