title: [Isolation and sequence analysis of a mitochondrial DNA fragment associated with CMS in Hong Lian type rice].
abstract: A CMS line specific mtDNA band TA1 was isolated by comparing the mtDNAs of CMS line and maintainer line using AFLP technique. The Northern blot analysis of the TA1 mtDNA fragment show that it transcripts only one RNA molecular each in CMS line, maintain line and the first filial generation, but the RNA moleculars are different among each other. By sequencing, the fragment is found to be 202 base pairs in length. It contains code ATG, ATT, AGA and AGG, two small repeated sequences 5'TGTAC3' and 5'ATTATTTT3' and one small inverted-repeated sequence 5'GGGAAACA3'. The results imply that the mtDNA fragment may be a coding region and may be relative to CMS of Hong Lian type rice.
