Rice as a staple food for billions has shaped the cultures,diets and economies. Rice production is supposed to increase 0.6-0.9% annually till 2050 to meet the demand arising from increase in population. However biotic and abiotic stresses pose major threat to rice production. Among the multiple abiotic stresses, drought is considered as the most critical threat to rice production and hence food security. Salinity is the second bigger abiotic challenge stress after drought.

        In rice, owing to the availability of high quality genomic sequence information, genome-wide expression microarray is a popular and widely used tool to assay and understand the mechanism of salinity and drought stress responsive genes. Many such expression profiles are available in rice across genotypes, tissues and growth stages. This database is a compilation of salt and drought responsive genes identified across different microarray experiments done in rice for which the raw data is available in NCBI GEO datasets. For the benefit of the breeders working on abiotic stress in rice, the microsatellites markers in the salt and drought responsive genes are also provided in this database which may help to assay gene-based polymorphisms.
