Inositide signalling Pollen Self-incompatibility Introduction Self-incompatibility (SI) is a mechanism used by many flowering plants to prevent self-pollination. In Papaver rhoeas L., var. Shirley, SI is controlled by a single, multi-allelic, gametophytically controlled S gene (Lawrence et al. ). Several alleles of the stigmatic S.

Self-incompatibility (SI) is a general name for several genetic mechanisms in angiosperms, which prevent self-fertilization and thus encourage outcross and should not be confused with genetically controlled physical or temporal mechanisms that prevent self-pollination, such as heterostyly and sequential hermaphroditism (dichogamy).

A region of the Papaver rhoeas genome encompassing part of the self-incompatibility S(1) locus has been cloned and sequenced.
The clone contains the gene encoding the stigmatic component of the response, but does not contain a putative pollen by: Abstract. The self‐incompatibility (SI) response in Papaver rhoeas depends upon the cognate interaction between a pollen‐expressed receptor and a stigmatically expressed ligand.
The genes encoding these components are situated within the S‐ order for SI to be maintained, the genes encoded by the S‐locus must be co‐inherited with no recombination Cited by: Lawrence MJ, O'Donnell S () The population genetics of the self-incompatibility polymorphism inPapaver rhoeas III.

Self‐incompatibility (SI) in Papaver rhoeas involves an allele‐specific recognition between stigmatic S‐proteins and pollen, resulting in inhibition of incompatible pollen. A picture of some of the signalling events and mechanisms involved in this specific inhibition of pollen tube growth is beginning to be built by: Identification of the pollen self-incompatibility determinant in Papaver rhoeas Article (PDF Available) in Nature () July with Reads How we measure 'reads'.

Gametophytic self- incompatibility (GSI) occurs when pollen is rejected in the style or on the stigma if it possesses a matching allele with either of the ovule parent's S-alleles. This mechanism typically involves a single genetic locus that is highly Author: Timothy Paape.

In the self-incompatible species Papaver rhoeas L., rejection of incompatible pollen is achieved through interaction of the female and male S-determinants, PrsS and PrpS, respectively. These S RNases have been demonstrated to confer self-incompatibility through transformation experiments (Lee et al., ; Murfett et al., ).
In Papaver, the stigmatic S gene encodes a small protein (Foote et al., ) that triggers a Ca 2+ -based signal transduction cascade resulting in the S -specific inhibition of incompatible pollen.
