General Information

General Information Comment Organism
physiological function T-DNA insertion in a gene encoding a putative inositol 1,3,4-trisphosphate 5/6-kinase, i.e. ITPK2, dsm3, leads to a drought- and salt-hypersensitive mutant. Under drought stress conditions, the mutant has significantly less accumulation of osmolytes such as proline and soluble sugar and shows significantly reduced root volume, spikelet fertility, biomass, and grain yield with concomittant increase in malondialdehyde level Overexpression of DSM3 in rice results in drought- and salt-hypersensitive phenotypes and physiological changes similar to those in the mutant. Inositol trisphosphate level is decreased in the overexpressors under normal condition and drought stress Oryza sativa
