Correlation between drought tolerance and ABA sensitivity in synthetic wheats and parental accessions.
(A) Scatter plot of drought tolerance and ABA sensitivity in the parental Ae. tauschii accessions. (B) Scatter plot of drought tolerance and ABA sensitivity in the synthetic lines. (C) Comparison of ABA sensitivity for three groups of Ae. tauschii accessions with distinct levels of drought tolerance. A, drought-sensitive accessions; B, accessions with moderate drought tolerance; C, highly drought-tolerant group. (D) Comparison of ABA sensitivity for three groups of synthetic wheats with distinct levels of drought tolerance. Student’s t-test was used to test for statistical significance (*P < 0.05) compared with the >45% survival group with low drought tolerance.
