Expression pattern of GmLAX genes under different stresses in soybean drought sensitive cultivar and tolerant cultivar
Auxin has been reported to regulate plant growth and development, as well as to mediate plant adaption to abiotic stresses, including drought. AUX/LAX family displays auxin uptake functions and comprises four highly conserved genes AUX1 and LIKE AUX1 (LAX1, LAX2, and LAX3) in Arabidopsis. There are...
