S R Saranya Krishnan, E A Siril
Somatic embryos were induced from internodal segment derived callus of Oldenlandia umbellata L., in MS medium supplemented with different concentrations of 2,4-Dichlorophenoxy acetic acid (2,4-D). Initially calli were developed from internodes of microshoots inoculated in 2.5 µM NAA supplemented medium. Then calli were transferred to 2,4-D added medium for somatic embryogenesis. Nutritional stress coupled with higher concentration of 2,4-D triggered somatic embryogenesis. Nutritional stress was induced by culturing callus in a fixed amount of medium for a period up to 20 weeks without any external supply of nutrients...

Agricultural productivity is severely hampered by drought in many parts of the globe. It is well-known that wild plant species can tolerate drought better when compared with their closely related cultivated plant species. Better drought adaptation of wild species over cultivated ones is accounted for their ability to differentially regulate gene expression. miRNAs, known to regulate gene expression at the post-transcriptional level, are admitted to play an important role in plant adaptation to stresses. This study aims at evaluating miRNA dynamics in a drought-tolerant wild Ipomoea campanulata L...

Glutathione (GSH; γ-glutamyl-cysteinyl-glycine) is a small intracellular thiol molecule which is considered as a strong non-enzymatic antioxidant. Glutathione regulates multiple metabolic functions; for example, it protects membranes by maintaining the reduced state of both α-tocopherol and zeaxanthin, it prevents the oxidative denaturation of proteins under stress conditions by protecting their thiol groups, and it serves as a substrate for both glutathione peroxidase and glutathione S-transferase. By acting as a precursor of phytochelatins, GSH helps in the chelating of toxic metals/metalloids which are then transported and sequestered in the vacuole...
