In this study, the activities of antioxidant enzymes, photosynthetic pigments, proline and carbohydrate contents in Pitcairnia encholirioides under ex vitro conditions of water deficit were evaluated. Results show that plants under progressive water stress, previously in vitro cultured in media supplemented with 30 g L-1 sucrose and GA3, accumulated more proline and increased peroxidase (POD) activity and the contents of photosynthetic pigments and carbohydrates. For plants previously in vitro cultured with 15 g L-1 sucrose and NAA, no differences were found for proline content and there were reductions in activities of peroxidase (POD), catalase (CAT) and poliphenoloxidase (PPO), and in contents of carbohydrates, with progress of ex vitro water deficit...

Anoectochilus roxburghii is a traditional Chinese medicine and natural health products. In the modern cultivation system, A. roxburghii is micropropagated in tissue culture, and the plants are transferred to soil cultivation for months. However, it remains unclear about the necessity of soil cultivation for the accumulation of health beneficial compounds. In this paper, we performed nontargeted metabolomic analysis using GC-TOF-MS and UPLC-Q-TOF-MS, on A. roxburghii plants at tissue culture stage or after 3 months of soil cultivation...

Cannabis ( Cannabis sativa L.) is an annual herbaceous plant that belongs to the family Cannabaceae. Trans -Δ9 -tetrahydrocannabinol (Δ9 -THC) and cannabidiol (CBD) are the two major phytocannabinoids accounting for over 40% of the cannabis plant extracts, depending on the variety. At the University of Mississippi, different strains of C. sativa, with different concentration ratios of CBD and Δ9 -THC, have been tissue cultured via micropropagation and cultivated. A GC-FID method has been developed and validated for the qualitative and quantitative analysis of acid and neutral cannabinoids in C...

"Masked mycotoxins" senso strictu are conjugates of mycotoxins resulting from metabolic pathways activated by the interplay between pathogenic fungi and infected plants. Zearalenone, an estrogenic mycotoxin produced by Fusarium spp, was the first masked mycotoxin ever described in the literature, but its biotransformation has been studied to a lesser extent if compared to other compounds such as deoxynivalenol. We presented herein the first application of organ and tissue culture techniques to study the metabolic fate of zearalenone in durum wheat, using an untargeted HR-LCMS approach...

It is of interest to apply plant tissue culture to generate plants resistant to toxic effects of cadmium (Cd) on plant growth. Callus cultures were initiated from leaf explants of micropropagated potato plantlets (Solanum tuberosum L., cv. Iwa) for in vitro selection comprising 18 different Cd treatments varying in Cd exposure timing and duration. Plantlets regenerated from two different lines of Cd-selected calli, L9 and L11, were found to exhibit enhanced resistance to 218 μM Cd compared to control (source plantlets for leaf explants used to initiate callus cultures for Cd resistance)...

Due to the limitations associated with shoot tip explants in the micropropagation of date palm, inflorescence explants are an ideal alternative. This chapter focuses on the protocol for the induction of callus from inflorescence tissue, establishment for proliferation of somatic embryos, germination, elongation, rooting, and acclimatization. Female inflorescences, 30-40 cm in length, cv. Shaishee, were used for culture initiation. After disinfection, the outer inflorescence cover (spathe) is cut open, and the spikelet explants, 1 cm long, are cultured on modified Murashige and Skoog (MS) medium containing 100 mg/L 2,4-D, 3 mg/L kinetin, and 3 mg/L 2ip and incubated at 25 ± 2 °C in the dark...

Date palm tolerates salinity, drought, and high temperatures. Arid and semiarid zones, especially the Middle East region, need a huge number of date palms for cultivation. To meet this demand, tissue culture techniques have great potential for mass production of plantlets, especially using the indirect embryogenesis technique; any improvement of these techniques is a worthy objective. Low levels of salinity can enhance growth and development of tolerant plants. A low level of seawater, a natural source of salinity, reduces the time required for micropropagation processes of date palm cv...

Date palm is a fruit-bearing tree commonly found in arid and semiarid regions. It is a dioecious plant, producing fruit on female plants and a limited number of basal offshoots for propagation. To produce large numbers of uniform plantlets, tissue culture techniques are required. It is highly advisable to detect genetic variation that may occur through micropropagation techniques as it may lead to phenotypic alterations. Random amplified polymorphic DNA (RAPD) is a simple and PCR-based molecular marker technique which can be employed to check the somaclonal variation...

Cryopreservation is the technology of choice not only for plant genetic resource preservation but also for virus eradication and for the efficient management of large-scale micropropagation. In this chapter, we describe three cryopreservation protocols (standard vitrification, droplet vitrification, and encapsulation vitrification) for date palm highly proliferating meristems that are initiated from vitro-cultures using plant growth regulator-free MS medium. The positive impact of sucrose preculture and cold hardening treatments on survival rates is significant...

Micropropagated plants experience significant stress from rapid water loss when they are transferred from an in vitro culture to either greenhouse or field conditions. This is caused both by inefficient stomatal control of transpiration and the change to a higher light intensity and lower humidity. Understanding the physiological, vascular and biomechanical processes that allow micropropagated plants to modify their phenotype in response to environmental conditions can help to improve both field performance and plant survival...

Saikat Gantait, Suprabuddha Kundu
Tylophora indica (Burm. f.) Merrill, an ethno-pharmacologically important perennial climber of Asclepiadaceae, is commonly known as Antamul or Indian ipecac. It is essentially accredited for its medicinal properties owing to its wide range of alkaloids in the form of bioactive secondary metabolites, such as tylophorine, tylophorinine, and tylophorinidine. Accelerated mass propagation of Tylophora is challenging because of its reduced seed germination frequency that consequently headed the pursuit for efficient protocols on in vitro propagation for the large-scale regeneration, conservation as well as sustainable supply of quality propagules...

Hyperhydricity occurs frequently in plant tissue culture and can severely affect commercial micropropagation and genetic improvement of the cultured plantlets. Hyperhydric shoots are charaterzized by high water content, but how this occurs is still a subject of investigation. Silver ion (Ag(+)) can reduce the extent of hyperhydricity in plants, but its effect on the reversion of hyperhydric plantlets and the underlying mechanism of reversion has not been clarified. In this study, about 67% of the hyperhydric Dianthus chinensis L...
