    A new insight into the phylogeny of vascular cryptogams with special reference to Selaginella and Isoetes inferred from nuclear ITS/5.8S rDNA sequences

    In order to provide a better understanding of the evolutionary history of vascular cryptogams, phylogenetic framework was developed based on ITS1, ITS2 and 5.8S rDNA sequences of 102 extant taxa of vascular crypt...

    Plant polyamines in abiotic stress responses

    Significance of naturally occurring intracellular polyamines (PAs), such as spermine, spermidine, and putrescine, in relation to the mechanism and adaptation to combat abiotic stress has been well established ...

    Spermidine-mediated in vitro phosphorylation of transcriptional regulator OSBZ8 by SNF1-type serine/threonine protein kinase SAPK4 homolog in indica rice

    Plants respond to abiotic stresses such as salinity, extreme temperature and drought by the activation of complex intracellular signaling cascades that regulate acclimatory biochemical and physiological change...

    Spermidine and abscisic acid-mediated phosphorylation of a cytoplasmic protein from rice root in response to salinity stress

    Importance of higher polyamines, spermidine, and spermine, in relation to the mechanism and adaptation to combat abiotic stress has been well established in cereals. Owing to their polycationic nature at physi...

    Trans-acting factor designated OSBZ8 interacts with both typical abscisic acid responsive elements as well as abscisic acid responsive element-like sequences in the vegetative tissues of indica rice cultivars

    Specific cis-acting elements, identified in the stress-regulated promoters, can respond to the changes in the levels of abscisic acid. Most of our previous works were done with ACGT-containing typical abscisic ac...
