“…The extensive research investigations on orchids have de ned success stories in orchid conservation, together with the cultivation of rare and novel varieties for global trade. Among the signi cant contributions, the contributions of ICAR-NRC, Sikkim, India is much appreciated; with major focus/contributions in the collection of orchid varieties, conservation and genetic resources utilization, and development of the National repository of orchids (Pamarthi et al, 2019).…”

Orchids constitute the largest and most diverse group of flowering plants and are classified in Orchidaceae. Exhibiting significance as the most exotic and ubiquitous flowering plants, the cultivation of orchids on a commercial level, is gaining momentum worldwide. In addition to its ornamental and aesthetic value, the orchid industry has been successful in generating employment for people in developing countries. Recent advances in biotechnological interventions in orchids have substantially contributed to the development of exotic varieties with novel traits, not to forget the inputs of traditional plant breeding methods and tissue culture approaches. In addition, the scientific developments in orchid biology have remarkably improved the knowledge in areas of orchid biology, classification, phytochemistry, and cultivation strategies, among other areas. This has facilitated the commercialization of novel varieties, opening new avenues in the orchid industry, witnessed as cultivation of different varieties and globally marketed as a cut flower and artificially propagated plants. The orchids constitute the first floriculture crops, which revolutionized the orchid industry, however, it also withholds several challenges in natural propagation, several species facing extinction. International organizations like CITES have come forward to address challenges associated with illegal global trade and indiscriminate use of orchid varieties, aiming towards conservation and legal commercial goals. This thematic review is one of a kind in providing comprehensive insights on the emerging momentum of orchid biology and how its globalization projects to considerably impact the orchid industry in the coming time. Together with traditional breeding approaches and plant tissue culture, advances in biotechnological interventions continues to make substantial progress in the development of exotic varieties, with multi-faceted attributes. However, it is imperative to understand the challenges in the cultivation and conservation of orchid varieties and ensure legislative guidelines both on domestic and global levels to ensure a multipronged approach for the conservation and commercialization of orchids.

“…Humans use orchids as cut flowers, bouquet, loose flowers, dried flowers, single flower mounts and pot plant displays. Their by‐products are used in making of handicrafts, traditional health care and in the perfumery industry (Meitei et al 2019, Pamarthi et al 2019, Singh et al 2019b).…”

Cymbidium whiteae King & Pantl is an endemic and endangered orchid species found in Sikkim, India. We evaluated the current population distribution and conservation needs of this species during 2017–2019 in North Sikkim, Sikkim, India. The distribution of the species ranged from 1020 to 1479 m a.s.l. but was confined to a small restricted area of the lower Dzongu region of North Sikkim district. The numbers of clumps at survey sites varied from 2 to 5 with a total population of 43 clumps at 17 sites. The flower number and capsules per clump varied from 4 to 12 and 3 to 12, respectively. Some flowering‐sized individuals neither flowered nor set any seed pods. Preliminary studies on asymbiotic seed germination indicated that seeds germinate on MS media supplemented with 0.2 mg BAP and develop into plantlets on the same media. We analysed the distribution pattern, prepared a distribution map, assessed the conservation status based on the IUCN criteria, and suggest suitable in situ and ex situ conservation measures and sustainable utilization. Based on the IUCN criteria, Cymbidium whiteae was assessed as critically endangered (CR).

Phalaenopsis amabilis (L.) Blume orchid is an Indonesian national flower. The number of these orchids in their natural habitat is very limited, therefore plant propagation efforts are needed. One of the promising methods is plant propagation by inserting embryo gene AtRKD4 from a model plant Arabidopsis thaliana into the orchid genome to produce many somatic embryos. From previous research, we have obtained 28 plant P. amabilis transformants carrying the AtRKD4 gene, however, it was unknown whether these plants have normal phenotypes and growth similar to their parents. Therefore, descriptions on growth and morphology are needed. This research aimed to evaluate the phenotype of P. amabilis carrying 35S::AtRKD4 the transformants grown in greenhouse. To achieve it, AtRKD4 gene integration stability on transformants genome was analyzed. Morphology and cross-section anatomy structure on transformant and non-transformant plantswere described. The stability of AtRKD4 gene integration in the plant genome was confirmed by amplification of the AtRKD4 gene from genomic DNA with Polymerase Chain Reaction (PCR) using a specific primer for AtRKD4 and ACTIN genes as the internal control. The quantitative data from morphology and anatomy measurements were analyzed statistically using ANOVA. The results showed that AtRKD4 was stably integrated into the genome of P. amabilis transformants and all transformant plants showed similar morphology and anatomy characteristics as non-transformant plants. The AtRKD4 embryo gene was stably integrated into the orchid genome and the transformant plants grow normally without significant changes in phenotype.
