We present here the comparative protective potentiality of exogenously applied polyamines (PAs), namely spermidine (Spd) and spermine (Spm), in mitigating NaCl toxicity and inducing short-term salinity tolerance in three indica rice varieties, namely M-1-48 (salt-sensitive), Nonabokra (salt-tolerant) and Gobindobhog (highly sensitive). The retardation in(More)
Salinity, drought and low temperature are the common forms of abiotic stress encountered by land plants. To cope with these adverse environmental factors, plants execute several physiological and metabolic responses. Both osmotic stress (elicited by water deficit or high salt) and cold stress increase the endogenous level of the phytohormone abscisic acid(More)
The present study investigated the linkages between drought stress, oxidative damages and variations in antioxidants in the three rice varieties IR-29 (salt-sensitive), Pokkali (salt-tolerant) and aromatic Pusa Basmati (PB), to elucidate the antioxidative protective mechanism governing differential drought tolerance. Water deficit, induced by 20% (w/v)(More)
In an attempt to understand the molecular basis of salt-stress response in the aromatic rice Gobindobhog, a comprehensive analysis encompassing physiological or biochemical assays and gene expression studies under high salt (200 mM NaCl) supply regimes were initiated and compared with a salt-sensitive (M-1-48) and salt-tolerant (Nonabokra) rice. The(More)
We present here a comprehensive study depicting the differences in biochemical responses to increasing CdCl2 concentrations (0.1, 0.25, 0.5 and 1.5 mM) in the two indica rice varieties, IR-29 (salt-sensitive) and Nonabokra (salt-tolerant), in order to contribute to our understanding of genotypic variation of cadmium tolerance. The oxidative damages in both(More)
In this communication, various in silico based prediction tools were employed to localize various stress-inducible genes [dehydrin (viz., RAB16A), polyamine-biosynthesis enzyme (viz., SAMDC), transcription factors (OSBZ8, NAC1, DREBP2, CRT/DRE-BP, WRKY24/51/71), ion channels and membrane transporters (HKT1, NHX1, SOS3) and protein kinases (SAPK5/7)] on rice(More)
The poor productivity and local confinement of indigenous aromatic rice varieties are mostly due to their susceptibility to salinity/drought/abscisic acid (ABA)-mediated abiotic stresses. It is thus essential to study the effects of several stress factors on their physiological parameters so as to improve their tolerance mechanism and enhance their global(More)
The efficiencies of different transformation methods of E. coli DH5Qalpha train, induced by several cations like Mg2+, Mn2+ Rb+ and especially Ca2+, with or without polyethylene glycol (PEG) and dimethyl sulfoxide (DMSO) were compared using the two commonly used plasmid vectors pCAMBIA1201 and pBI121. The widely used calcium chloride (CaCl2) method appeared(More)
The present study considered transcriptional profiles and protein expression analyses from shoot and/or root tissues under three abiotic stress conditions, namely, salinity, dehydration, and cold, as well as following exogenous abscisic acid treatment, at different time points of stress exposure in three indica rice varieties, IR-29 (salt sensitive),(More)
Extensive investigation into plant response and adaptation to diverse osmotic stresses like high salt/dehydration/low temperature, involving a broad spectrum of cellular physiological and biochemical changes, is essential to unravel intrinsic mechanism to mitigate against such stresses. In our previous communications, we conducted biochemical analyses of(More)
