Stylar Transmitting Tissue of Transgenic Tobacco
Tobacco was transformed with a gene coding for an S-locus-specific glycoprotein of Brassica oleracea. The resulting transgenic plants showed tissue-specific and developmentally regulated expression of the introduced gene. lmmunolocaliration experiments showed that the Brassica gene was expressed in the stylar transmitting tissue of the transgenic plants. The pattern of expression of the introdu...
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 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...

تمایل به ارزیابی جایگزین و تعویض آن با آزمون سنتی مداد و کاغذ در سالهای اخیر افزایش یافته است. اکثر زبان آموزان در کلاس های زبان از نمره نهایی که استاد تعیین میکند ناراضی اند. این تحقیق جهت بررسی ارزیابی در کلاس های زبان انگلیسی به هدف رضایتمندی زبان آموزان از نمره هایشان انجام گرفته است که در آن نمرات ارائه شده توسط سه گروه ارزیاب (ارزیابی خود دانشجو، همسالان واستاد) در مهارت های تولید (تکل...
15 صفحه اولThe S15 self-incompatibility haplotype in Brassica oleracea includes three S gene family members expressed in stigmas.
Self-incompatibility in Brassica is controlled by a single, highly polymorphic locus that extends over several hundred kilobases and includes several expressed genes. Two stigma proteins, the S locus receptor kinase (SRK) and the S locus glycoprotein (SLG), are encoded by genes located at the S locus and are thought to be involved in the recognition of self-pollen by the stigma. We report here ...
