Overcoming inter-subspecific hybrid sterility in rice by developing indica-compatible japonica lines
Rice (Oryza sativa L.) is an important staple crop. The exploitation of the great heterosis that exists in the inter-subspecific crosses between the indica and japonica rice has long been considered as a promising way to increase the yield potential. However, the male and female sterility frequently occurred in the inter-subspecific hybrids hampered the utilization of the heterosis. Here we rep...
متن کاملGenetic complexity underlying hybrid male sterility in Drosophila.
Recent genetic analyses of closely related species of Drosophila have indicated that hybrid male sterility is the consequence of highly complex synergistic effects among multiple genes, both conspecific and heterospecific. On the contrary, much evidence suggests the presence of major genes causing hybrid female sterility and inviability in the less-related species, D. melanogaster and D. simula...
متن کاملGenetic interactions underlying hybrid male sterility in the Drosophila bipectinata species complex.
Understanding genetic mechanisms underlying hybrid male sterility is one of the most challenging problems in evolutionary biology especially speciation. By using the interspecific hybridization method roles of Y chromosome, Major Hybrid Sterility (MHS) genes and cytoplasm in sterility of hybrid males have been investigated in a promising group, the Drosophila bipectinata species complex that co...

the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
15 صفحه اولTransfer of Cytoplasmic Male Sterility into Rice
Transfer of Cytoplasmic Male Sterility into Rice Diversifying the existing cytoplasmic male sterility (CMS) sources of rice is indispensable for a sustainable production system of hybrid seed. Ahmadikhah et al. report that maintainer line Yosen B was converted to a CMS line (Yosen A) in three generations by markerassisted backcrossing. The recurrent parent genome content of the final CMS line w...
