Angiosperm mitochondrial genomes are more complex than those of other organisms. Analyses of the mitochondrial genome sequences of at least 11 angiosperm species have showed several common properties; these cannot easily explain, however, how the diverse mitotypes evolved within each genus or species. We analyzed the evolutionary relationships of Brassica(More)
Androgenesis is an efficient method of producing doubled haploids (DHs) in plant breeding programs. DH plants derived from the F1 (broccoli × white-headed cabbage) are valuable for accelerating the transfer of excellent genes and increasing biodiversity of species via isolated microspore culture (IMC). Therefore, this study investigated the developmental(More)
