Abstract
With the accumulating genome sequences and their positional information, comparative genomics has become feasible in Lotus japonicus. As a first trial, synteny analysis of L. japonicus was carried out against Arabidopsis thaliana and Medicago truncatula.
Synteny analysis between L. japonicus and A. thaliana was performed on the basis of gene-by-gene comparison. Currently, syntenic relations consisting of 3 or more genes were found in 65% of annotated L. japonicus clones. On the other hand, when the assigned syntenic regions were plotted on each chromosomal position, no clear macrosyntenic relationship was observed.
Regarding to the synteny between L. japonicus and M. truncatula, syntenic relations was found in 45% of annotated L. japonicus clones. Significant level of macrosyntenic relation was found when these syntenic relations were plotted on the linkage map.
The latest status of the synteny analyses of L. japonicus will be presented.
