Comparative and phylogenetic study on the chloroplast genomes of CMS with the cytoplasm of Aegilops ovata and its maintainer line in wheat.

ABSTRACT: BACKGROUND : Aegilops ovata a wild relative of wheat. As a valuable genetic source, it can be used for wheat breeding and improvement. However, the interspecific variation, evolutionary mechanism and phylogenetic relationship of the chloroplast genome from the nucleoplasmic hybrid between Ae. ovata and wheat are still unclear. RESULTS: In this study, the CMS line (Ae.ovata)-Xinong1376 and its maintainer line Xinong1376 were used as the materials. We compared their phenotypes. The anthers of (Ae.ovata)-Xinong1376 were indehiscent and lighter in color at the late stage of microspore development, and the male gametophytes lacked starch. The abortion appeared at binucleate stage. Subsequently, we assembled and compared the chloroplast genomes of the CMS line (Ae. ovata)-Xinong1376 and its main
