Cytoplasmic male sterility is a maternally inherited trait in higher plants that prevents the production of functional pollen. Ogura cytoplasmic male sterility in radish (Raphanus sativus) is regulated by the orf138 mitochondrial locus. Male fertility can be restored when orf138 accumulation is suppressed by the nuclear Rfo locus, which consists of three genes putatively encoding highly similar...
BACKGROUND The use of cytoplasmic male sterility (CMS) in F1 hybrid seed production of chili pepper is increasingly popular. However, the molecular mechanisms of cytoplasmic male sterility and fertility restoration remain poorly understood due to limited transcriptomic and genomic data. Therefore, we analyzed the difference between a CMS line 121A and its near-isogenic restorer line 121C in tra...
Cytoplasmic male sterility has been found independently in soybean three times since 1995, but no microscopic investigation has been published. The purpose of this microscopic study was to establish the developmental sequence leading to sterility in a cytoplasmic male-sterile soybean line that has been found to be stable under all environmental conditions tested and to demarcate the temporal an...
To produce a good F1 hybrid variety wheat crop, it is necessary to explore novel cytoplasmic male sterility (CMS) lines and their maintainer line. This study aimed to identify cytoplasmic variation in three isonuclear-alloplasmic male sterile lines Aegilops kotschyi (Ae.kots) -90-110, Aegilops ventricosa (Ae.ven) -90-110, and Triticum spelta (T.spelta) -90-110 and their maintainer line, A-90-11...
The practice of hybridization has greatly contributed to the increase in crop productivity. A major component that exploits heterosis in crops is the cytoplasmic male sterility (CMS)/nucleus-controlled fertility restoration (Rf) system. Through positional cloning, it is shown that heterozygous alleles (RsRf3-1/RsRf3-2) encoding pentatricopeptide repeat (PPR) proteins are responsible for restori...
