Recent Development in Micropropagation Techniques for Rare Plant Species

Abstract

The current investigation aimed to present an overview of the conservation of biological diversity of rare and endangered plant species. Methods of biodiversity conservation as well as several overview recommendations for the preservation of various rare species have been considered. An overview of the taxa included in the red book has been presented on the example of the Russian Federation. Global and local codes and classifiers of plant rarity were also presented. Future prospects for the conservation of biological diversity and the creation and development of bioresource collections have been considered.

High Frequency Direct Organogenesis, Genetic Homogeneity, Chemical Characterization and Leaf Ultra-Structural Study of Regenerants in Diplocyclos palmatus (L.) C. Jeffrey

“…The conventional way of propagating D. palmatus through seeds is ineffective due to its low viability and germination rate [28]. Advanced in vitro techniques in biotechnology have enabled us to multiply, preserve and propagate several rare/endangered plant species of medicinal value [29]. The micropropagation of medicinal plants through in vitro techniques has a tremendous potential for producing superior quality planting materials, isolating useful variants in well-adapted high yielding genotypes with enhanced secondary metabolites of therapeutic potential, and has a number of advantages over traditional methods of propagation such as seed, cutting, grafting, and air-layering, etc.…”

Molecular Determinants of in vitro Plant Regeneration: Prospects for Enhanced Manipulation of Lettuce (Lactuca sativa L.)

“…Plant tissue culture to achieve in vitro regeneration was originally used to answer fundamental questions in plant biology but has since evolved to be foundational for genetic improvement, micropropagation, genetic engineering, and biotechnology ( Michelmore et al, 1987 ; Zhang et al, 2006 ; Loberant and Altman, 2010 ; Xu and Huang, 2014 ; Chokheli et al, 2020 ). However, in vitro regeneration is not possible for all plant species and regeneration is very genotype dependent.…”

Micropropagation and Cryopreservation of Yukon Draba (Draba yukonensis), a Special Concern Plant Species Endemic to Yukon Territory, Canada

“…Micropropagation is a useful technique for the conservation of endangered plants through mass propagation [3][4][5][6][7][8]. The application of micropropagation with conservation priority has saved several economically important plant species from extinction.…”

“…For example, Himalayan Chickpea (Cicer microphyllum), an endemic wild relative of chickpea (Cicer arietinum), has been successfully micropropagated and used in conservation and breeding programs [12]. Thus, micropropagation techniques offer significant help in the revival of endangered plant species and as such, the technique may also be applied to plants of commercial importance [5,13].…”
