Background Cymbidium ensifolium L. is known for its ornamental value and is frequently used in cosmetics. Information about the salt stress response of C. ensifolium is scarce. In this study, we reported the physiological and transcriptomic responses of C. ensifolium leaves under the influence of 100 mM NaCl stress for 48 (T48) and 96 (T96) hours. Results Leaf Na+ content, activities of the antioxidant enzymes i.e., superoxide dismutase, glutathione S-transferase, and ascorbate peroxidase, and malondialdehyde content were increased in salt-stressed leaves of C. ensifolium. Transcriptome analysis revealed that a relatively high number of genes were differentially expressed in CKvsT48 (17,249) compared to CKvsT96 (5,376). Several genes related to salt stress sensing (calcium signaling, stomata closure, cell-wall remodeling, and ROS scavenging), ion balance (Na+ and H+), ion homeostasis (Na+/K+ ratios), and phytohormone signaling (abscisic acid and brassinosteroid) were differentially expressed in CKvsT48, CKvsT96, and T48vsT96. In general, the expression of genes enriched in these pathways was increased in T48 compared to CK while reduced in T96 compared to T48. Transcription factors (TFs) belonging to more than 70 families were differentially expressed; the major families of differentially expressed TFs included bHLH, NAC, MYB, WRKY, MYB-related, and C3H. A Myb-like gene (CenREV3) was further characterized by overexpressing it in Arabidopsis thaliana. CenREV3’s expression was decreased with the prolongation of salt stress. As a result, the CenREV3-overexpression lines showed reduced root length, germination %, and survival % suggesting that this TF is a negative regulator of salt stress tolerance. Conclusion These results provide the basis for future studies to explore the salt stress response-related pathways in C. ensifolium.

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).

“…In Australia, C. madidam and C. canaliculatum were used by Aborigines and early settlers as food and traditional medicine. Their pseudobulbs were chewed as a cure for dysentery, and seeds of C. madidam were used as oral contraceptive (8,29). Moreover, Cymbidium flowers are also used as an ingredient in perfume, skin cream and antiaging cosmetics (29).…”

Chemical investigation of two orchids native to Thailand led to the isolation of eighteen compounds. From the whole plants of Cymbidium finlaysonianum Wall. ex Lindl, a new dihydrophenanthrene, 1-(4-hydroxybenzyl)-2,7-dihydroxy-4,6-dimethoxy-9,10-dihydrophenan-threne, and nine known stilbenoids, including a phenanthrenequinone, cymbinodin-A, a dihydrophenanthrenequinone, ephemeranthoquinone B,� a bibenzyl, batatasin III, two phenanthrenes, 2,4-dimethoxy-3,7-dihydroxyphenanthrene and 3,7-dihydroxy-2,4,6-trimethoxyphenanthrene, and four dihydrophenanthrenes i.e. coelonin, 6-methoxycoelonin, flavanthridin and lusianthridin, were obtained. From the roots and leaves of Paphiopedilum dianthum Tang & Wang, two new stilbene dimers, paphiodianthins A and B, were isolated along with three known stilbenes i.e. pinosylvin monomethyl ether, 2,3'-dihydroxy-5'-methoxystilbene and (E)-2,5'-dihydroxy-2'-(4-hydroxybenzyl)-3'-methoxystilbene, and three known flavonoids i.e. isalpinin, pinocembrin and galangin. The chemical structures of these compounds were determined by spectroscopic techniques including UV, IR, MS and NMR, as well as comparison with previously reported data. These isolated compounds were assayed for their cytotoxicity against colon (Caco-2), breast (MCF-7) and lung (NCI-H187) cancer cell lines, as well as two resistant sublines of MCF-7 cells (MCF-7/DOX and MCF-7/MX), by MTT and resazurin microplate assays. Among compounds isolated from C. finlaysonianum, cymbinodin-A displayed the strongest cytotoxicity against almost all cancer cell lines tested (Caco-2, NCI-H187, MCF-7/DOX and MCF-7/MX), whereas coelonin was the most cytotoxic constituent against MCF-7 cell line. Other compounds from this orchid were moderately cytotoxic. From P. dianthum, (E)-2,5'-dihydroxy-2'-(4-hydroxybenzyl)-3'-methoxystilbene and paphiodianthin A exhibited the strongest cytotoxic effect against all cell lines tested, while pinosylvin monomethyl ether and paphiodianthin B were strongly cytotoxic to MCF-7 cells, but were moderately toxic or non-toxic to normal cells (NIH/3T3). Moreover, isalpinin was more cytotoxic to MCF-7/DOX subline than to MCF-7 cell line and was non-toxic to normal cell line.
