Self-incompatibility genes of Brassica oleracea: Expression, isolation, and structure.
We demonstrate by in situ hybridization the cell-type-specific expression of transcripts encoded by the self-incompatibility (S) locus of Brassica oleracea. These transcripts are not detected early in stigma development, their expression is switched on in the papillar cells of the stigma surface, and their levels increase in these cells in correlation with the acquisition by the stigma of the s...
متن کاملExpression of a self-incompatibility gene in a self-compatible line of Brassica oleracea.
In cruciferous plants, self-pollination is prevented by the action of genes situated at the self-incompatibility locus or S-locus. The self-incompatibility reaction is associated with expression of stigma glycoproteins encoded by the S-locus glycoprotein (SLG) gene. Only a few cases of self-compatible plants derived from self-incompatible lines in the crucifer Brassica have been reported. In th...
متن کاملAntigenotoxic Effects of Brassica oleracea L
The herbicide cilluron containing cyhalofop-butyl (10%) is an active ingredient. Cyhalofop-butyl has low oral, dermal and inhalation toxicity. In the present study the antigenotoxic effects of Brassica oleracea L. var. italica was evaluated using Allium cepa root chromosomal aberration assay against ciluron. Three types of treatments were given to roots in pre-treatment roots were first treated...
متن کامل[Molecular mechanism of self-incompatibility in Brassica].
In Brassica species, self-incompatibility has been mapped genetically to a single chromosomal location. In this region several closely linked genes have been identified. One of them, S-locus receptor kinase (SRK), determines S haplotype specificity of the stigma and it's the key protein for SI reaction. The role of the S locus glycoprotein (SLG) gene remains unclear. In the last decade approxim...
متن کاملChromosome Doubling of Microspore-Derived Plants from Cabbage (Brassica oleracea var. capitata L.) and Broccoli (Brassica oleracea var. italica L.)
Chromosome doubling of microspore-derived plants is an important factor in the practical application of microspore culture technology because breeding programs require a large number of genetically stable, homozygous doubled haploid plants with a high level of fertility. In the present paper, 29 populations of microspore-derived plantlets from cabbage (Brassica oleracea var. capitata) and brocc...
