| Abstract: | We mapped 25 Arabidopsis thaliana drought-inducible genes. Responsive to Dehydration (RD) and Early Responsive to Dehydration (ERD), to the Arabidopsis genome and compared map positions with those of mutants that show environmental stress response. We hybridized CIC yeast artificial chromosome (YAC) library filters with the cDNAs and determined the map positions of 18 corresponding genes. We screened the P1 library with 7 other clones and analyzed segregation of their restriction fragment length polymorphisms (RFLP) in recombinant inbred (RI) lines. One cDNA could be mapped because it had been sequenced by the Arabidopsis genome sequencing program. |
