Research on cytoplasmic genome characterization of chrysanthemum, Pyrus, Allium, and their relatives.

In MAS, some crops have more valuable information from cytoplasmic genomes than nuclear genome. Cytoplasmic genomes and chromosomes of 48 horticultural crops and their wild relatives including Denranthema spp. (=Chrysanthemum), Allium spp. and Pyrus spp. have been characterized as a research project supported by National Agricultural Genome Center. So far, more than 20 chloroplast genomes were completely sequenced and characterized. Chloroplast genomes of Dendranthema spp. were 151,017~151,175-bp in size; LSC 82,821~82,886, IR 24,954~24971, and SSC 18,282~18,347. Chloroplast genomes of chrysanthemum cultivars (Chrysanthemum grandiflorum ) were similar to that of Denranthema boreale, than that of other 4 Denranthema spp. Chloroplast genomes of Pyrus spp. were 159,884~159,992-bp in size; LSC 87,862~87,892, IR 26,392, and SSC 19,237~19,238. Pyrus cp genomes are 2~4kb bigger than other known Rosaceae. Chloroplast genome of Chinese pear, P. bretschneideri CV Yali, was similar to that of Pyrus pylifoia CV Hosui, by having same gene sequence and genome structure, except for variation in IGS regions and introns. Chloroplast genomes of Allium spp. were 153,216~151,586-bp in size; LSC 82,395~82,699, IR 26,466~26,478, and SSC 17,825~17,931. Among the 4 MS lines of A. cepa showed variation in genes, introns, and IGS. These include SNPs in genes, monomeric and large repeats in introns, and SNPs, large INDELs, inversions in IGS. For Allium, detailed investigation in mitochondrial genomes is planned. This research incorporated with cytological and nuclear genome researches will give us useful information in MAS and better understanding in crop evolution.
