Fig. 4From: Genome-wide identification and characterization of ABA receptor PYL/RCAR gene family reveals evolution and roles in drought stress in Nicotiana tabacumAlignment and conserved motifs of NtPYLs. Amino acid sequence alignment of the 29 NtPYLs and AtPYL2 was performance by ClustalW. a Secondary structural elements are indicated above the primary sequence. Helices and sheets/strands are shown as black helices and arrows, respectively. The four conserved ABA receptor region CL1-CL4 are indicated with red lines. The conserved motifs analysis of the NtPYLs based on their phylogenetic relationship were identified using MEME software. b In left panel, the members of each subfamily are indicated with the same color and different NtPYL subfamilies are represented by the Roman numeral I-III in the phylogenetic tree. In right panel, grey lines represent non-conserved sequences, and colored boxes numbered at the bottom indicate different motifs. The length of motifs in each NtPYL protein is shown proportionallyBack to article page
