A novel herbicide-inducible male sterility system.
BACKGROUND Heterosis is a phenomenon that first-generation offspring perform better than their parents. Conventional breeding methods have their shortcomings. It would be optimal to construct inducible male sterile plants. RESULTS We developed a novel system for creating male sterile transgenic plants by downregulating the specific expression of the glyphosate tolerance CP4 EPSPS gene in male...
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 کاملFertility compensation of cornerstone male sterility of wheat by rye.
The genome of rye is known to compensate for the lost male-fertility gene(s) of wheat chromosome arm 4Aalpha in the Cornerstone male-sterility mutant. A search for the rye chromosome(s) involved in this compensation showed that chromosomes 2R and 4R are responsible. Only the short arms of these two chromosomes are the operative ones. Chromosome arm 4RS compensates in an erratic way, whereas 2RS...
متن کاملSterility in Wheat Hybrids. I. Sterility Relationships and Endosperm Development.
Partial or complete sterility is of frequent occurrence in species crosses. Within the same genus certain species are sterile when crossed while ather combinations are completely fertile. Partial sterility may cause the elimination of certain classes of gametes and prevent desired recombinations of characters in the second generation. Sterility may also cause an abnormal vegetative development....
متن کاملA TRIM insertion in the promoter of Ms2 causes male sterility in wheat
The male-sterile ms2 mutant has been known for 40 years and has become extremely important in the commercial production of wheat. However, the gene responsible for this phenotype has remained unknown. Here we report the map-based cloning of the Ms2 gene. The Ms2 locus is remarkable in several ways that have implications in basic biology. Beyond having no functional annotation, barely detectable...
