Abstract:
Introgression of Japanese bunching onion (Allium fistulosum, FF) into the genome of onion (A. cepa, AA) has been attempted before. However, we are still unable to introduce it directly multiple times. One of several reasons is that the progeny of interspecific hybrids between shallot and Japanese bunching onion is sterile. There is a difference in the mode of chiasma formation between shallot (AA) and Japanese bunching onion (FF) as one of the cause of sterility. Allium cepa forms randomized chiasmata (ring-shaped), A. fistulosum forms localized chiasmata (cross-shaped). We tried to reveal the expression mechanism of this phenotype by conducting cytogenetic observation, differential expression analysis of chromosome pairing-associated transcriptomes in alien monosomic addition lines (AMALs) and phylogenetic analysis. In cytogenetic analysis using eight kinds of AMALs (FF+1A-FF+8A; 2n=2x+1=17), it suggested that the control factor of chiasma formation is located on FF+2A. In differential expression analysis, it suggested that MSH2 gene is the candidate gene responsible for controlling chiasma formation. In phylogenetic analysis, the function and genetic relationship between MSH gene of Japanese bunching onion and bulb onion, and other plants were revealed.
