Main conclusion Fine mapping of wheat powdery mildew-resistance genePm4eto a 0.19cM interval with sequence-based markers provides the foundation for map-based cloning and marker-assisted selection with breeder-friendly markers.Powdery mildew caused by Blumeria graminis f. sp. tritici is a wheat foliar disease that poses a serious threat to global wheat production. Pm4 is a resistance gene locus that...
Main conclusion Four typical ALTERNATIVE OXIDASE genes have been identified in tea plants, and their sequence features and gene expression profiles have provided useful information for further studies on function and regulation. Abstract Alternative oxidase (AOX) is a terminal oxidase located in the respiratory electron transport chain. AOX catalyzes the oxidation of quinol and the reduction of...
Main conclusion Transformation from q to Q during wheat domestication functioned outside the boundary of threshability to increase yield, grains m−2, grain weight and roundness, but to reduce grains per spike/spikelet.Mutation of the Q gene, well-known affecting wheat spike structure, represents a key domestication step in the formation of today’s free-threshing, economically important wheats. In...
Main conclusionIn this study, we reported that a F-box protein, OsADF,as one of the direct targets ofTDR, plays a critical role in rice tapetum cell development and pollen formation. Abstract The tapetum, the innermost sporophytic tissue of anther, plays an important supportive role in male reproduction in flowering plants. After meiosis, tapetal cells undergo programmed cell death...
