Cytoplasmic male sterility (CMS), widely used in the production of hybrid seeds, is a maternally inherited trait resulting in a failure to produce functional pollen. In order to identify some specific proteins associated with CMS in pepper, two-dimensional gel electrophoresis (2-DE) was applied to proteomic analysis of anthers/buds between a CMS line (designated NA3) and its maintainer (designa...

Apart from their agronomic importance in hybrid seed production, mutations that encode cytoplasmic male sterility (CMS) provide a means to probe the role of the mitochondrion in reproductive development. Fertility restorers are examples of nuclear genes that affect cytoplasmic gene expression, and their identification can illuminate the interactions between the two genomes. In this review, we c...

Plant male sterility has often been associated with mitochondrial dysfunction; however, the mechanism in wheat (Triticum aestivum L.) has not been elucidated. This study set out to probe the mechanism of physiological male sterility (PHYMS) induced by the chemical hybridizing agent (CHA)-SQ-1, and cytoplasmic male sterility (CMS) of wheat at the proteomic level. A total of 71 differentially exp...

The development of F1 hybrid varieties of wheat is reviewed under four main headings: male sterility, hybrid seed production, the performance of hybrids and commercial aspects. The three systems for male sterility used in wheat (cytoplasmic male sterility, nuciear male sterility and chemical hybridizing agents) are described and it is noted that no system is without problems or has a clear adva...

the cytoplasmic male sterile (cms) lines that are used in production of hybrid seeds in three-line system often get contaminated with their maintainer lines. using such impure cms lines in rice hybrid seed production lead to un-uniformity and yield loss in hybrid rice. laborious and time consuming phenotypic evaluations are used for elimination of off-type plants in cms multiplication farms. th...

The recessive genetic male sterility (RGMS) system plays a key role in the production of hybrid varieties in self-pollinating B. napus plants, and prevents negative cytoplasmic effects. However, the complete molecular mechanism of the male sterility during male-gametogenesis in RGMS remains to be determined. To identify transcriptomic changes that occur during the transition to male sterility i...
