Nucleotide polymorphism in the drought responsive gene Asr2 in wild populations of tomato
The Asr gene family (named after abscicic acid [ABA], stress, ripening), exclusively present in plant genomes, is involved in transcriptional regulation. Its members are up-regulated in roots and leaves of water- or salt-stressed plants. In previous work, evidence of adaptive evolution (as inferred...
