Fig. 5From: Genome-wide identification and characterization of ABA receptor PYL/RCAR gene family reveals evolution and roles in drought stress in Nicotiana tabacumAlignment of the conserved CL2 regions in ABA receptors (PYLs) in Arabidopsis, soybean, and cultivated tobacco. Multiple amino acid sequence alignment of the full-length PYLs from Arabidopsis, soybean, and cultivated tobacco was carried out by ClustalW algorithm. Black line indicates the conserved CL2 loop/region in ABA receptor PYLs; asterisk indicates the position of the two key amino acidsBack to article page
