Gene, protein, and network of male sterility in rice
Rice is one of the most important model crop plants whose heterosis has been well-exploited in commercial hybrid seed production via a variety of types of male-sterile lines. Hybrid rice cultivation area is steadily expanding around the world, especially in Southern Asia. Characterization of genes and proteins related to male sterility aims to understand how and why the male sterility occurs, a...
متن کاملA Dominant Gene for Male Sterility in Salvia miltiorrhiza Bunge
A natural male sterile mutant of Salvia miltiorrhiza (Labiatae, Sh-B) was found during field survey in 2002. Our objective was to analyze its genetic mechanism for producing F1 hybrid seeds and to develop a molecular marker linked to male sterile gene for selection of a hybrid parent line. The segregation ratios of male sterile plants to fertile plants in the progenies of both testcross and bac...
متن کاملFine mapping and candidate gene identification of a recessive genic male sterility gene (Bnms3) in rapeseed
On the basis of the previous mapping study for male sterility gene Bnms3, we further narrowed it from a genomic region of 470kb to 93.7kb, using a large population consisting of 1339 fertile and 1151 sterile plants, and locus specific markers derived from Brassica rapa of A10. Seventeen open reading frames (ORFs) were predicated in the target region. Of them, two most likely candidate genes wer...
متن کاملpH-dependent modulation of voltage gating in connexin45 homotypic and connexin45/connexin43 heterotypic gap junctions.
Intracellular pH (pH(i)) can change during physiological and pathological conditions causing significant changes of electrical and metabolic cell-cell communication through gap junction (GJ) channels. In HeLa cells expressing wild-type connexin45 (Cx45) as well as Cx45 and Cx43 tagged with EGFP, we examined how pH(i) affects junctional conductance (g(j)) and g(j) dependence on transjunctional v...
متن کاملThe Possible Role of Atp6 Gene in Cytoplasmic Male Sterility in WA (Wild Abortive) Type of Rice (Oryza sativa L.)
The possibility of occurrence of some rearrangements inside and or around coxII and atp6 genes and their relationship with male sterility in rice lines having wild abortive (WA) cytoplasm was studied. Two sterile (IR58025A and IR62829A) and two maintainer lines (IR58025B and IR62829B) were used. Radioactive Southern blotting was employed to carry out the experiments. The hybridization of coxII...
