The species of this family are facing tremendous pressure due to habitat degradation, overexploitation and changing environmental conditions. Therefore, while exploring the floristic diversity of NUPA, attempts were made to explore the orchid diversity, distribution patterns, nativity, endemism, threat categories, and local uses.

Quang Truc forest (QTF) is a remote area in the South-West of Dak Nong province, Vietnam, which is well known for valuable timber species representative for central highland of Vietnam with different globally and nationally threatened species. However, the general understanding of plant diversity of QTF has been still poorly known. The objectives of this paper are to figure out the plant diversity of QTF and compare that with other protected forest areas in Dak Nong province, in order to provide scientific evidences for conservation and sustainable development.

Transposable elements (TEs) are fragments of DNA that can insert into new chromosomal locations. They represent a great proportion of eukaryotic genomes. The identification and characterization of TEs facilitates understanding the transpositional activity of TEs with their effects on the orchid genome structure.

Closely related hybridizing species are ideal systems for identifying genomic regions underlying adaptive divergence. Although gene expression plays a central role in determining ecologically-based phenotypic differences, few studies have inferred the role of gene expression for adaptive divergence in Neotropical systems.

Result of study on the diversity of orchids in Southern East Viet Nam at 6 study sites from July 2019 to October 2020 have identified 173 orchids species belong to 50 diffrent genus, accounting for 14.41% of the total number of orchid species available in Viet Nam (1.200 species). Among them, all species were used as ornamental plants; 13 species were used for medicinal herbs; and 6 species were listed for conservation in Vietnam Red Data Book, (2019).

Orchids are the most fascinatingly beautiful flowers and unique group of plants of nature. With their exotic shapes, hues and the added advantage of longevity, these flowers of rare beauty have become increasingly popular in the 21st century. They belong to the Orchidaceae family and consisting 600-800 genera and 25,000-35,000 species.

The import of orchid cut flowers has increased from 299.09 in 2008-09 to 3405.36 lakhs in 2015-16 (Anon., 2016).Orchids being tropical flower have a longer shelf life, as a result, they are marketed globally as cut flowers used for different purposes like flower arrangement, bouquets, corsages, stage decoration, floral jewellery, potted plant and as bedding ground orchids. Cymbidiums are leading cut flowers among orchids while Phaelanopsis are extensively used as pot plants and Dendrobiums are popular in tropical countries.

Phaius tankervilliae (L’Her.) Blume is one of the most attractive and horticulturally valuable ground orchids of the world. Due to illegal collection for trade and consumption and loss of habitat, the population of this species has decreased rapidly at an alarming rate in natural habitats. In vitro seed germination and seedling development of Phaius tankervilliae technique was successfully established...

Orchids are the most beautiful flowering, highly evolved ornamental plants and also have medicinal importance. In the present study, genetic diversity among six Dendrobium species was analysed using morphological characters and molecular markers including RAPD and SSR markers. Morphological characters analysed were leaf shoot and flower characters of six Dendrobium species. The variability in morphology was found among the species. Further, the genetic diversity among the species was determined by using RAPD and SSR markers.

India is recognized as a significant producer of orchids in the world. Nearly 1300 species of orchids are found in India which constitutes almost 10 percent of the world orchid flora with Himalayas as their main home (Medhi and Chakrabati, 2009). Orchids are amongst the most advanced flowering plants, highly specialized in many ways. They are distributed all over the world except the Antarctica (Ali and Mir, 2013).
