Exon/intron structures of PLCPs from soybean, L. japonicus, M. trunctula and A. thaliana. 181 PLCPs were classified into nine groups, namely Group A to Group I (according to the classification in Fig. 2). The pale green box represents exons, the plum red represents UTR, the black line refers introns, slashes represent over-longed introns, and the scales at the top are used to estimate the sizes of exons and introns
