Identification and structure of LEC2 from castor bean (RcLEC2). (A) Phylogenic analysis of deduced amino acids of three Arabidopsis TFs that each contain a B3 domain (LEC2, FUS3, and ABI3) and their most homologous three genes from castor bean, 30190.m010868, 30132.m006860, and 30204.m001803, respectively. Amino acid sequences were aligned using the ClustalW method, and the tree was constructed using the program DNASTAR MegAlign (Ver. 7.2.1). (B) Amino acid alignment of LEC2 proteins from castor bean (RcLEC2) and Arabidopsis (AtLEC2). (C) Structures of cDNAs that encode LEC2 from castor bean and Arabidopsis. Hypothetical protein, XP_002509459, which is encoded by an mRNA transcribed from 30190.m010868 genomic DNA in castor bean. The hypothetical protein XP_002509459 contains a 19-aa sequence (LCTHSTEETGEVFPHARRQ, between aa residues 267 and 284) that this not found in RcLEC2.
