Genetic Control of Self-Incompatibility in Centromadia (Hemizonia) Pungens Subsp. Laevis (Madiinae, Asteraceae)

The presence of se lf-incompatibility was tested in Centroma dia pun gens subsp. laevis and (he gene tic basis of the se lf-incompatib ility respon se was ex plored using crossing stud ies. We performed full d iallel c ross ing experiments amo ng 10 ind ividuals from one natural population and four F, families . We observed a strong se lfinco mpaubility resp onse in a ll indi viduals tested . w...

Genetic control of quantitative variation in self-incompatibility proteins detected by immunodiffusion.

Single radial immunodiffusion was used to study the self-incompatibility (S) proteins present in stigmas of two inbred lines of Brassica oleracea: a self-incompatible line and a self-compatible mutant derived from it. The genetic basis of observed quantitative differences in S proteins between the two inbreds was shown to be determined by a single gene with dosage effects. Self-pollination of i...

Genetic evidence that two independent S-loci control RNase-based self-incompatibility in diploid strawberry

The self-incompatibility mechanism that reduces inbreeding in many plants of the Rosaceae is attributed to a multi-allelic S locus which, in the Prunoideae and Maloideae subfamilies, comprises two complementary genes, a stylar-expressed S-RNase and a pollen-expressed SFB. To elucidate incompatibility in the subfamily Rosoideae, stylar-specific RNases and self-(in)compatibility status were analy...

Self-incompatibility in Papaver

Self-fertilization, which results in reduced fitness of offspring, is a common problem in hermaphrodite angiosperms. To prevent this, many plants utilize self-incompatibility (SI), which is determined by the multi-allelic S locus, that allows discrimination between self (incompatible) and non-self (compatible) pollen by the pistil. In poppy (Papaver rhoeas), the pistil S-determinant (PrsS) is a...
