Tropospheric ozone is major abiotic stress which severely affects the growth and development of plants being phytotoxic in nature. In order to cope up with ozone stress, plants exhibit a plethora of morphological, physiological and molecular changes. Molecular studies have played a role to decipher the mechanism underlying the phytotoxic impact of ozone stress. Various studies have been performed and a variety of genes exhibiting expression in response to ozone stress have been identified. Since it is very important to understand the molecular regulation of gene expression for ozone stress response to develop the ozone resistant crop varieties, OSRGD ver.1.1 provides a user friendly interface that integrates the ozone stress-specific microarray and transcriptome dataset of different plant species. This comprehensive bio-curation will offer researchers a better biological insight into plant response to ozone stress. To get started click on the plant species below.
