Pan-genome Identification of CsYABBYs and Validation of Drought Stress Responses in Tea Plants
results showed that four near-core genes, CsYABBY7, CsYABBY9, CsYABBY10, and CsYABBY11, were relatively conserved and under purifying selection during tea domestication. In addition, expression patterns showed their differential responses to drought stress. Functional experiments further confirmed that overexpression of CsYABBY7/10/11 could reduce the accumulation of reactive oxygen species and increase the activities of osmoregulatory substances and antioxidant enzymes, thereby enhancing drought resistance. Inhibition of these genes has the opposite effect. CsYABBY9 exhibits dosage-sensitive regulation, in which both overexpression and knockdown compromise drought tolerance.
