Leaf senescence induced by 2,4-dichlorophenoxyacetic acid (2,4-D) and senescence inhibition caused by supplementation with silver (Ag(+)) ions in the form of silver nitrate (AgNO(3)) or silver nanoparticles (AgNPs) were investigated in 8-day-old mung bean (Vigna radiata L. Wilczek) seedlings. Inhibition of root and shoot elongation were observed in mung… (More)
A protocol for high frequency production of somatic embryos was worked out in pigeonpea, Cajanus cajan (L.) Millsp. The protocol involved sequential employment of embryogenic callus cultures, low density cell suspension cultures and a novel microdroplet cell culture system. The microdroplet cell cultures involved culture of a single cell in 10 μI of… (More)
The influence of exogenous estrogen on the action of 7,12-dimethylbenz[alpha]anthracene (DMBA) on ovaries of Swiss albino mouse has been studied. DMBA elicits the depletion of oocytes; but concomitant administration of estrogen with DMBA reduces this loss of oocytic population significantly.
Liposomes entrapping fluorescein diacetate were fused with protoplasts of Datura innoxia Mill by employing polyethylene glycol (PEG) as the fusogen. Factors that influence liposome-protoplast fusion were optimized as a function of PEG-concentration and incubation duration, liposome composition and surface charge and liposome:protoplast ratio.… (More)
Phosphatidylinositol (PtdIns) is a major phospholipid in eukaryotic cells. Many studies have revealed that the phosphoinositide (PI) signaling pathway plays an important role in plant growth and development. Phospholipase C (PLC) is reported to have a crucial role in the PI pathway. This work focuses on the isolation and investigation of PLC in response to… (More)
