“…Research Laboratory (RRL) Jammu (added later) under the G-15 GEBMAP program with Department of Biotechnology (DBT), Ministry of Science and Technology, GoI, as nodal agency. This has not only given better focus and thrust especially on collection and conservation of medicinally important threatened species but also helped in consolidating the ongoing efforts in the country (Sharma and Pandey 2013;Sharma et al 2019Sharma et al , 2020. JNTBGRI herbal garden has a collection of 1,200 taxa herbals in an area of 10 acres (KSCSTE-JNTBGRI 2019).…”

A wide array of medicinal plants in India, primarily used by locals for health care, have found wide acceptance and adoption globally (either directly or processed) due to distinct advantages of good results, low or no side-effects and ease of access to general public. Indigenous and traditional systems of medicine in practice since historical times have shown potential (direct or indirect as immune-boosters) against many dreaded ailments including the recent global pandemic of COVID-19. With prediction of sixth mass extinction, there is worldwide concern as majority of these plants, collected from natural stands, are also facing threat of extinction. Since 1990s concerted efforts have been directed towards assessment of threat status, the basic requirement for prioritizing conservation activity to various species of plants and animals. In literature there is staggered information regarding list of threatened plants, including medicinal plants of India, compiled at either state level or national or international level. Analysis of these publications led to collation of a consolidated list of 84 species and the same is presented here. A brief account of conservation efforts in India at national level and supportive policy framework is also included. This compilation is aimed to serve as a comprehensive reference especially for beginners, researchers, conservationists, foresters, pharmaceutical professionals as well as policy makers.

“…Synthetic seeds have been used as a highly efficient vegetative method to propagate and distribute plant germplasm (Gantait et al 2015;Rihan et al 2017;Kulus 2019;Sharma et al 2019). Synthetic seeds are artificially encapsulated miniature cuttings that provide the functions of a natural seed but, like cuttings, remain true-to-type to their donor plant (Cheruvathur et al 2013;Gantait and Mitra 2019).…”

Synthetic seed propagation of the therapeutic-honey plants

Context Increasing demand for therapeutic honey has driven establishment of Leptospermum nectar plantations. Methods for propagation involving synthetic seeds (artificially encapsulated miniature cuttings) may speed production of Leptospermum polygalifolium Salisb. and L. scoparium J.R.Forst. & G.Forst. Aims The study aimed to determine how nutrient strength of the encapsulation solution and the presence of benzyladenine (BA) in the emergence medium affect shoot and root emergence from synthetic seeds of L. polygalifolium and L. scoparium. Methods Nodes from in vitro shoots of three L. polygalifolium clones (P1, P6, P11) and two L. scoparium clones (S6, S12) were encapsulated in 3% sodium alginate with half- or full-strength Murashige and Skoog (MS) medium, and the synthetic seeds were placed on full-strength MS emergence medium containing 0 or 2.2 μM BA. Key results Full-strength MS in the encapsulation solution was effective for shoot emergence of both species. BA increased the percentage of synthetic seeds with shoot emergence in clone P6 but decreased the percentage in clone S12. BA stimulated shoot emergence through callus in clones P1, P6, S6 and S12, and increased the number of shoots per emergent synthetic seed in clones S6 and S12. Surprisingly, the simple use of full-strength MS medium without hormones was highly effective for adventitious rooting, stimulating root emergence and plantlet formation in 26–57% of L. polygalifolium and 100% of L. scoparium synthetic seeds. Conclusions These two Leptospermum species are highly amenable to propagation via synthetic seeds. A simple formulation of hormone-free, full-strength MS medium in the encapsulation solution and emergence medium provides high frequencies of plantlet conversion. Implications Synthetic seeds have potential to assist in mass production of Leptospermum plants for nectar plantations to meet demand for therapeutic honey.
