Asr genes belong to a gene family comprising at least three closely linked loci on chromosome 4 in tomato

Asr1, Asr2 and Asr3 are three homologous clones isolated from tomato whose expression is believed to be regulated by abscisic acid (ABA); the corresponding genes thus participate in physiological and developmental processes such as responses of leaf and root to water stress, and fruit ripening. In t...
