Effect of Explant Type in Development of in vitro Micropropagation Protocol of an Endangered Medicinal Plant: Curcuma caesia Roxb.
Occasionally when a plant species is difficult to propagate with traditional methods or in danger of extinction, and in many cases very often both, we must place our faith in science and the lab-coated coves initiated in such sorcery! Micropropagation is the growing of plants from seed or tiny pieces of plant tissue in sterile, laboratory conditions, and is utilised to cultivate those dreadful nuisances that are indifferent to a tray of John Innes and a bit of bottom heat. Kew’s Micropropagation Unit was set up in 1974 and produces thousands of plants each year to repopulate endangered species in a series of labs dedicated to this cultivation. Orchids are one of the success stories at Kew, with this plant family in particular need of specialist techniques. Although they often produce thousands of seeds orchids rely upon fungi in the soil for germination, as theses dust-like seeds lack an endosperm, the part of a seed where a small food store powers the initial stages of germination, before the first leaves are unfurled and photosynthesis becomes the main engine for plant growth. The soil fungi form a symbiotic relationship with the tiny seed, laying on the food that enables germination! This happy matrimony is undoubtedly heart-warming, but from a propagation perspective is insanely difficult to recreate in the potting shed, needing the usual temperature and moisture requirements plus that blasted fungi. As usual science holds the key with micropropagation enabling germination without fungus, in a process called asymbiotic germination that provides all of the nutrients that the fungus would normally supply. This propagation usually does not involve soil, but instead various cocktails of sugars, minerals and vitamins solidified in agar jelly, which holds the concoction together and gives the plants something to root into. The development and success of these techniques has resulted in the saving of species such as the beautiful Lady’s Slipper Orchid, Cypripedium calceolus, which had been reduced to one single specimen left in the wild but was repopulated and reintroduced in a collaboration between Kew and English Nature! Cryopreservation is used to store plant tissue and seeds, freezing material at -196°C (-320°F) in these sealed tanks with liquid nitrogen! Tiny orchid seed is smeared on to the agar jelly mixture Sincere apologies for the quality of this image, but looking down the lens of a microscope we can see thin grains of orchid seed and the round, swelling seed that has already began to germinate Eventually roots and shoots develop from the germinated seed Seedlings are ‘potted on’ to glass jars, where they continue to develop before eventually being finally transferred to traditional soil potting mixtures and then reintroduced to the wild! Micropropagation does not just involve seeds; here new shoots are developing on a miniature cutting Some species are not terribly fond on the agar jelly cocktails, so a rough plug mixture is used instead Even succulents can be raised with this method! Carnivorous plants, Dionaea muscipula, can be seen here. As the nutrients in the agar mixture are used up, yellowing leaves on the plants indicate the time to pot on to a soil based medium It’s propagation, but not as we know it! A little off the beaten track, but I hope this offers an insight into some of the madness going on here at Kew!

The aim of this protocol was to develop an alternative in vitro propagation system for Cannabis sativa L. by mimicking nursery-based vegetative propagation. Photoautotrophic micropropagation (PAM) was achieved on rockwool blocks as substrate combined with commercially available fertilizer suitable for cannabis cultivation. Stock plants were initiated after sterilisation in forced-ventilated glass jars which then provided a continuous supply of shoot tip and nodal cuttings. A 97.5% rooting rate of in vitro shoot tip cuttings and successful acclimatisation were achieved within 3 weeks in glass vessels with passive ventilation.

Abstract In this investigation MS media supplemented with different concentrations of GA3 viz. 0.00, 0.12, 0.25, 0.50, 0.75mg/L were used for in vitro micro propagation of potato varieties Cardinal and Desiree. The parameters included were percent sprout, plantlet height, number of nodes per plantlet, number of days to root initiation, and number of days to transferable height of the plantlets. Statistical analysis showed that the varieties, GA3 concentration and varieties vs GA3 concentration were highly significant for plant height, number of nodes per plantlet and number of days to transferable height of the plantlets. Plantlets developed in M.S media supplemented with 0.25 mg/L of GA3 for Desiree and 0.12mg/L of GA3 for Cardinal produce maximum plant height, more number of nodes, reduced no. of days to root initiation and took less number of days to transferable height of the plant. Plantlets developed in these treatments were healthy and vigorous than the plantlets developed in o
The white dead nettle (Lamium album L.) is a herb that was successfully subjected to in vitro micropropagation followed by ex vitro adaptation back to the natural habitat. The L. album micropropagation system offers a combination of factors (light intensity, temperature, carbon dioxide level, humidity) that are limiting for plant growth and bioactive capacity. Here, we performed comparative investigation on the primary and secondary metabolism in fully expanded L. album leaves during the consecutive growth in in vivo, in vitro, and ex vitro conditions. The micropropagation did not affect the general leaf anatomy but it caused permanent decrease in the number of palisade mesophyll layers and the hydrocarbon content in the essential oils. During the in vitro conditions, the thylakoid membrane structure was altered, the photosynthetic performance was reduced, and the content of primary and secondary metabolites declined. The plant transfer back to the field led to resumption of both normal growth and general bioactive capacity. The present work broadens the understanding about the nature of plant responses towards environmental conditions.

Micropropagation has become a reliable and routine approach for large-scale rapid plant multiplication, which is based on plant cell, tissue and organ culture on well defined tissue culture media under aseptic conditions. A lot of research efforts are being made to develop and refine micropropagation methods and culture media for large-scale plant multiplication of several number of plant species. However, many forest and fruit tree species still remain recalcitrant to in vitro culture and require highly specific culture conditions for plant growth and development. The recent challenges on plant cell cycle regulation and the presented potential molecular mechanisms of recalcitrance are providing excellent background for understanding on totipotency and what is more development of micropropagation protocols. For large-scale in vitro plant production the important attributes are the quality, cost effectiveness, maintenance of genetic fidelity, and long-term storage. The need for appropriate in vitro plant regeneration methods for woody plants, including both forest and fruit trees, is still overwhelming in order to overcome problems facing micropropagation such as somaclonal variation, recalcitrant rooting, hyperhydricity, polyphenols, loss of material during hardening and quality of plant material. Moreover, micropropagation may be utilized, in basic research, in production of virus-free planting material, cryopreservation of endangered and elite woody species, applications in tree breeding and reforestation.
