Abstract: • A LEA family gene (PtrLEA7) was cloned from Poncirus trifoliata. • PtrLEA7 was strongly induced by stresses and ABA. • PtrLEA7 played a positive role in modulation of drought tolerance. • Overexpression of PtrLEA7 elevated antioxidant capacity.

Background Drought stress markedly constrains plant growth and diminishes crop productivity. Strigolactones (SLs) exert a beneficial influence on plant resilience to drought conditions. Nevertheless, the specific function of SLs in modulating cotton’s response to drought stress remains to be elucidated. Results In this study, we assess the impact of exogenous SL ( rac -GR24) administration at various concentrations (0, 1, 5, 10, 20 µM) on cotton growth during drought stress. The findings reveal that cotton seedlings treated with 5 µM exogenous SL exhibit optimal mitigation of growth suppression induced by drought stress. Treatment with 5 µM exogenous SL under drought stress conditions enhances drought tolerance in cotton seedlings by augmenting photosynthetic efficiency, facilitating stomatal closure, diminishing reactive oxygen species (ROS) generation, alleviating membrane lipid peroxidation, enhancing the activity of antioxidant enzymes, elevating the levels of osmoregulatory compounds, and upregulating the expression of drought-responsive genes. The suppression of cotton SL biosynthesis genes, MORE AXILLARY GROWTH 3 ( GhMAX3 ) and GhMAX4b , impairs the drought tolerance of cotton. Conversely, overexpression of GhMAX3 and GhMAX4b in respective Arabidopsis mutants ameliorates the drought-sensitive phenotype in these mutants. Conclusion These observations underscore that SLs significantly bolster cotton’s resistance to drought stress.
