Nucleotide Polymorphisms at the Drought Candidate Gene Loci of Arabidopsis Thaliana and Their Association Study with Drought Index and Functional Study of ATHK1
The levels of drought tolerance and nucleotide polymorphism at transcription factor CBF4, ATHK1 and key enzyme regulating abscisic acid (ABA) synthesis NCED3 locus in a worldwide sample of 32 core accessions of Arabidopsis thaliana were examined. The results showed that different accessions had quite difference in adaptation to drought stress. Thirty-two core accessions of Arabidopsis thaliana were classified in four clusters by synthetical analysis of drought tolerance.
The frequency of nucleotide...
