Instability of s male-sterile cytoplasm in maize.
A number of S male-sterile plants from several shrunken-2 inbred lines were crossed initially with an R138-TR inbred line pollinator carrying the nonrestoring genotype for S sterile cytoplasm. One such cross, involving a male-sterile female parent from inbred line M825, produced, unexpectedly, a number of male-fertile F(1) progeny, along with the expected male-sterile off-spring. Pollen records...
متن کاملProteolytic activity in anther extracts of fertile and cytoplasmic male sterile petunia.
Proteolytic activity is compared in anther extracts from Petunia parodii fertile and cytoplasmic male sterile lines. It is characterized relative to developmental stage of the anthers, effect of variable incubation times, pH of isolation buffers, and degradation of marker proteins. In fertile anthers, proteolytic activity increases at the end of microsporogenesis and peaks early in microgametog...
متن کاملFertility Restoration of the Sorghum A3 Male- Sterile Cytoplasm through a Sporophytic Mechanism Derived from Sudangrass
Fertility restoration of sorghum [Sorghum bicolor (L.) Moench] lines carrying the IS1112C (A3 group) male-sterile cytoplasm has been documented as a two-gene gametophytic mechanism involving complementary action of restoring alleles designated Rf3 and Rf4, as derived from IS1112C. Fertility restoration capability has also been reported from sudangrass (S. bicolor subsp. drummondii) populations....
متن کاملMitochondrial DNA rearrangements and transcriptional alterations in the male-sterile cytoplasm of Ogura radish.
Maternally inherited mutations, such as cytoplasmic male sterility, provide useful systems in which to study the function of plant mitochondrial genomes and also their interaction with nuclear genes. We have studied the organization and expression of the organelle genomes of the male-sterile cytoplasm of Ogura radish and compared them with those of normal radish to identify alterations that mig...
متن کاملThe male sterile G cytoplasm of wild beet displays modified mitochondrial respiratory complexes.
Cytoplasmic male sterility (CMS) in higher plants has been mainly studied in cultivated species. In most cases, pollen abortion is linked to the presence of an additional mitochondrial polypeptide leading to organelle dysfunction in reproductive tissues. In wild beet, both CMS and hermaphrodite plants coexist in natural populations. The G cytoplasm is widely distributed along the Western Europe...
