6. Analysis of the sequence showed that this fragment had no homology with all of the male sterility genes which had been reported, and part of this fragment was highly homologous with part of BAC clone KBrB042N05 and KBrB041L12 sequences in Brassica rapa. This suggested that the newly detected fragment related to cytoplasmic male sterility and properly came from nuclear DNA.
