A transgenic self-incompatible Arabidopsis thaliana model for evolutionary and mechanistic studies of crucifer self-incompatibility.
Molecular genetic studies of self-incompatibility (SI) can be difficult to perform in non-model self-incompatible species. Recently, an Arabidopsis thaliana transgenic model was developed for analysis of the SI system that operates in the Brassicaceae by inter-species transfer of genes encoding the S-locus receptor kinase (SRK) and its ligand, the S-locus cysteine-rich (SCR) protein, which are ...
متن کاملA Cryptic Modifier Causing Transient Self-Incompatibility in Arabidopsis thaliana
Breakdown of the pollination barrier of self-incompatibility (SI) in older flowers, a phenomenon known as pseudo-self-compatibility or transient SI, has been described as an advantageous reproductive assurance strategy that allows selfing after opportunities for out-crossing have been exhausted [1-9]. Pseudo-self-compatibility is quite prevalent as a mixed mating strategy in nature, but the und...
متن کاملExpression of distinct self-incompatibility specificities in Arabidopsis thaliana.
The interplay of balancing selection within a species and rapid gene evolution between species can confound our ability to determine the functional equivalence of interspecific and intergeneric pairs of alleles underlying reproduction. In crucifer plants, mating specificity in the barrier to self-fertilization called self-incompatibility (SI) is controlled by allele-specific interactions betwee...
متن کاملFunctional test of Brassica self-incompatibility modifiers in Arabidopsis thaliana.
The self-incompatibility (SI) system of the Brassicaceae is based on allele-specific interactions among haplotypes of the S locus. In all tested self-incompatible Brassicaceae, the S haplotype encompasses two linked genes, one encoding the S-locus receptor kinase (SRK), a transmembrane kinase displayed at the surface of stigma epidermal cells, and the other encoding its ligand, the S-locus cyst...
متن کاملSelf-incompatibility: How to Stay Incompatible
Plant self-incompatibility is controlled by different genes for the recognition reactions of pollen and stigmas, yet correct association of the two genes have been maintained in two Brassica species.
