Comparison and evolution analysis of two rice subspecies LATERAL ORGAN BOUNDARIES domain gene family and their evolutionary characterization from Arabidopsis
چکیده انگلیسی

The plant specific LATERAL ORGAN BOUNDARIES (LOB) domain (LBD) gene family has a potential role in lateral organ development. Thirty-five LBD genes in a japonica rice (Nipponbare) (designated OsJLBD) and in an indica rice (9311) (designated OsILBD) were identified based on the current databases of the two rice subspecies. A new rice LBD gene with two LOB domains and two predicted coiled coil structures in both subspecies was found, which is not found in other plant species based on the current NCBI Genbank database. OsJLBD and OsILBD genes have similar chromosomal distribution pattern. Both OsJLBD and OsILBD genes can be divided into 7 subclasses (classes Ia–e, II and III (see Table 1)) and no subclass-specific expression pattern was observed. No introns have been predicted in all class Ie genes in both OsJLBD and OsILBD subfamilies. The genome and tandem duplication has contributed to the neofunctionalization and formation of new rice subclasses, but the mechanism of diploidization and limited tandem duplication have contributed to fewer LBD genes in rice than in Arabidopsis. Functional studies of genes in subclasses may help to determine whether special sequence structure (intron–exon, spacing characters of motifs) has caused special expression pattern of subclasses.
