Rice (Oryza sativa L.; Family: Poaceae)) is an important food crop for the humankind. Drought incidences have become frequent in the past few decades due to increasing aberration in rainfall patterns. Drought stress at plant establishment and reproductive stage limits crop production and is becoming a more severe problem in many regions of the globe. Response of plant to various biotic and abiotic stress is quite complex and is in turn a function of multitude of intrinsic and extrinsic factors. A systematic study into the genes governing the drought stress response has been explored by many researchers. However, a comprehensive study on the secondary regulation or response to drought stress in rice still lacking.

MicroRNAs (miRNAs) are endogenous single-stranded non-coding RNA molecule of approximately 22 nucleotides that bind to partially complementary sequence from their target genes. miRNAs function like a tiny super soldier which regulate the expression various genes and play importance role in various physiological, developmental and morphological processes. This database is designed with the aim of identifying the drought responsive known and novel miRNAs from the publically available small RNA-seq data under drought stress from different genotypes at vegetative and reproductive stage.
