Genetic Engineering of Male Sterility for Hybrid Seed Production
In order to prevent self-pollination in some plants like corn, tomato and cabbage, emasculation of the female line by hand is required, raising costs and labor expenses of seed production. The utilization of naturally occurring cytoplasmatic male-sterility (cms) is a more efficient approach. Mostly correlated with changes in the mitochodrial or chloroplast DNA, in some lines of distinct species...
متن کاملMitochondrial complementation and cytoplasmic male sterility in wheat.
RTIFICIAL mixtures of mitochondria from various unrelated inbred lines A of maize exhibit oxidative and phosphorylative activities which correspond to the activities of mitochondria of hybrids of these lines ( SARKISSIAN and SRI~ASTAVA 1967; MCDANIEL and SARKISSIAN 1968). This phenomenon has been called mitochondrial complementation (MCDANIEL and SARKISSIAN 1966). Complementation reflects dissi...
متن کاملA long noncoding RNA regulates photoperiod-sensitive male sterility, an essential component of hybrid rice.
Hybrid rice has greatly contributed to the global increase of rice productivity. A major component that facilitated the development of hybrids was a mutant showing photoperiod-sensitive male sterility (PSMS) with its fertility regulated by day length. Transcriptome studies have shown that large portions of the eukaryotic genomic sequences are transcribed to long noncoding RNAs (lncRNAs). Howeve...
متن کاملA further evaluation of hybrid wheat
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...
متن کاملSelective response to H-Y antigen by F1 female mice sensitized to F1 male cells
T-cell mediated cytotoxic responses to H-Y antigen require co-recognition of H-Y and H-2 gene products. F1 mael stimulating cells and target cells express H-Y antigen in association with both parental H-2 haplotypes. However, F1 females primed in vivo and challenged in vitro with F1 male cells lyse male target cells of F1 and only one parental H-2 haplotype. Thus, (CBA X B10)F1 females sensitiz...
