complete sequence of heterogenous-composition mitochondrial genome (brassica napus) and its exogenous source. | unlike maternal inheritance of mitochondria in sexual reproduction, somatic hybrids follow no obvious pattern. the introgressed segment orf138 from the mitochondrial genome of radish (raphanus sativus) to its counterpart in rapeseed (brassica napus) demonstrates that this inheritance mode derives from the cytoplasm of both parents. sequencing of the complete mitochondrial genome of five species from brassica family allowed the prediction of other extraneous sources of the cybrids from the radish ... | 2012 | 23190559 |
origin of the cms gene locus in rapeseed cybrid mitochondria: active and inactive recombination produces the complex cms gene region in the mitochondrial genomes of brassicaceae. | cms (cytoplasmic male sterile) rapeseed is produced by asymmetrical somatic cell fusion between the brassica napus cv. westar and the raphanus sativus kosena cms line (kosena radish). the cms rapeseed contains a cms gene, orf125, which is derived from kosena radish. our sequence analyses revealed that the orf125 region in cms rapeseed originated from recombination between the orf125/orfb region and the nad1c/ccmfn1 region by way of a 63 bp repeat. a precise sequence comparison among the related ... | 2010 | 21317543 |
physical localization and genetic mapping of the fertility restoration gene rfo in canola (brassica napus l.). | the ogu cytoplasm for male sterility and its fertility restorer gene rfo in canola (brassica napus l.) were originally introgressed from radish (raphanus sativus l.) and have been widely used for canola hybrid production and breeding. the objective of this study was to determine the physical location of the rfo locus in the canola genome using fluorescence in situ hybridization and genetic mapping. for physical localization of the rfo gene, two bacterial artificial chromosome (bac) clones, g62 a ... | 2009 | 19370095 |
characterization of raphanus sativus pentatricopeptide repeat proteins encoded by the fertility restorer locus for ogura cytoplasmic male sterility. | 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 pentatricopeptide repeat proteins (ppr-a, -b, and -c). we produced transgenic rapeseed (brassica napus ... | 2008 | 19098270 |
