We investigated the effect of wheat germ agglutinin (WGA) on plant resistance to salinity. We showed that treatment of wheat seedlings with exogenous WGA resulted in an increase in cell division and elongation. Incubation of 4-d-old seedlings in 2% NaCl solution for 24 h resulted in appreciable decrease in mitotic activity of meristem cells in roots and growth of whole seedlings. At the same ti...

Although allelic diversity of genes has been shown to contribute to many phenotypic variations associated with different physiological processes in plants, information on allelic diversity of abiotic stress-responsive genes is limited. Here it is shown that the alleles OsWRKY45-1 and OsWRKY45-2 play different roles in abscisic acid (ABA) signalling and salt stress adaptation in rice. The two al...

Saline to freshwater invasions have become increasingly common in recent years. A key hypothesis is that rates of freshwater invasions have been amplified in recent years by increased food concentration, yet this hypothesis has remained unexplored. We examined whether elevated food concentration could enhance freshwater tolerance, and whether this effect evolves following saline to freshwater i...

Context Soil salinity is a serious environmental issue that drastically reducing crop productivity via limiting the uptake of important micronutrients including iron (Fe) and zinc (Zn). Aims To identify wheat genotypes with better Fe Zn potential under saline conditions. Methods The seedlings eight (SARC-1, SARC-2, SARC-3, SARC-4, SARC-5, SARC-6, SARC-7 SARC-8) were exposed to (100 mM NaCl), de...

Genome duplication (or polyploidization) has occurred throughout plant evolutionary history and is thought to have driven the adaptive radiation of plants. We found that the cytotype of the root, and not the genotype, determined the majority of heritable natural variation in leaf potassium (K) concentration in Arabidopsis thaliana. Autopolyploidy also provided resistance to salinity and may rep...

Soil salinity problems are widespread around the globe with increased risk of spreading over the years. The fungus Piriformospora indica, identified in Indian Thar desert, colonizes the roots of monocotyledon plants and provides resistance towards biotic as well as abiotic stress conditions. We have identified a cyclophilin A-like protein from P. indica (PiCypA), which shows higher expression l...
