Suppressed expression of Retrograde-Regulated Male Sterility restores pollen fertility in cytoplasmic male sterile rice plants.
Conflict/reconciliation between mitochondria and nuclei in plants is manifested by the fate of pollen (viable or nonviable) in the cytoplasmic male sterility (CMS)/fertility restoration (Rf) system. Through positional cloning, we identified a nuclear candidate gene, RETROGRADE-REGULATED MALE STERILITY (RMS) for Rf17, a fertility restorer gene for Chinese wild rice (CW)-type CMS in rice (Oryza s...
متن کاملA pentatricopeptide repeat-containing gene restores fertility to cytoplasmic male-sterile plants.
Known in over 150 species, cytoplasmic male sterility is encoded by aberrant mitochondrial genes that prevent pollen development. The RNA- or protein-level expression of most of the mitochondrial genes encoding cytoplasmic male sterility is altered in the presence of one or more nuclear genes called restorers of fertility that suppress the male-sterile phenotype. Cytoplasmic male sterility/rest...
متن کاملRestorer-of-Fertility Mutations Recovered in Transposon-Active Lines of S Male-Sterile Maize
Mitochondria execute key pathways of central metabolism and serve as cellular sensing and signaling entities, functions that depend upon interactions between mitochondrial and nuclear genetic systems. This is exemplified in cytoplasmic male sterility type S (CMS-S) of Zea mays, where novel mitochondrial open reading frames are associated with a pollen collapse phenotype, but nuclear restorer-of...
متن کاملFertility alteration behaviour of Thermosensitive Genic Male Sterile lines in Rice Oryza sativa L
The utilization of thermosensitive genic male sterility system (TGMS) has great potential for revolutionizing hybrid rice production in tropical countries through simple, less expensive and efficient seed production technology without any limitation in fertility restoration which have been the hindrance for commercial exploitation of heterosis in rice using cytoplasmic genic male sterility syst...
متن کاملFertility restoration in cytoplasmic-nuclear male-sterile lines derived from 3 wild relatives of pigeonpea.
Three cytoplasmic-nuclear male-sterile (CMS) lines, one each derived from Cajanus sericeus (A(1) cytoplasm), Cajanus scarabaeoides (A(2) cytoplasm), and Cajanus cajanifolius (A(4) cytoplasm), were crossed to 7 pigeonpea (Cajanus cajan (L.) Millsp.) cultivars in a line x tester mating scheme to study the fertility restoration of the CMS lines. Twenty-one F(1) hybrid combinations were planted in ...
