Abstract:
LOG genes encode riboside 5′-monophosphate enzymes,which could directly transform cytokinin precursors into cytokinins with physiological activities,thus acting essential roles in the biosynthetic pathways of cytokinins.To further research the LOG gene family functions of Chinese cabbage,bioinformatics tools were conducted to identify the LOG gene family members in the Chinese cabbage genome,and genome annotation,physiological and biochemical characteristics of proteins,gene structures,conserved domains and phylogenetic trees were also analyzed.The results showed that 17 LOG genes were identified in the whole genome level,which could be clustered into 7 clades,A-G；LOG genes were unevenly distributed in the 10 chromosomes,among which chromosome 2 and chromosome 4 contained relatively more LOG genes.Multiple alignment of LOG protein sequences were conducted and results indicated the consensus sequences of MHxRKAxMx（5)FxALPGGYGTxxEE,which was specific to LDC motif in LOG proteins.Besides,8 conserved motifs were predicted among LOG proteins by MEME analysis.These results established certain foundation for LOG gene functions study in Chinese cabbage.
