Abstract

Expression of an S receptor kinase (SRK910) transgene in self-compatible Brassica napus cr. Westar conferred on the transgenic pistil the ability to reject pollen from the self-incompatible Brassica napus W1 line, which carries the S-910 allele. In one of the SRK transgenic lines, 1C, virtually no seeds were produced when the transgenic pistils were pollinated with W1 pollen (Mean number of seeds per pod = 1.22). This response was specific to the W1 pollen since pollen from a different self-incompatible Brassica napus line (T2) and self-pollinations were fully compatible. Westar plants expressing an S locus glycoprotein transgene (SLG(910)) did not show any self-incompatibility response towards W1 pollen. Transgenic Westar plants resultingfrom crosses between the 1C SRK transgenic line and three SLG(910) transgenic lines were also tested for rejection of W1 pollen. The additional expression of the SLG(910) transgene in the SRK910 transgenic plants did not cause any significant further reduction in seed production (Mean seeds/pod = 1.04) or have any detectable effects the number of pollen grains that adhered to the pistil. Thus, while the allele-specific SLG gene was previously reported to have an enhancing effect on the self-incompatibility response, noevidence for such a role was found in this study.
