Molecular Biology Of S-Rnase-Based Self-Incompatibility

2008
Many Flowering Plants Have Developed Self-Incompatibility (Si) Systems To Avoid Inbreeding And To Promote Out-Crossing. Among The Various Si Systems, Gametophytic Si (Gsi) In The Solanaceae, Plantaginaceae And Rosaceae Is Believed To Be The Most Common Type, In Which The Specificity Of Si Response Is Controlled By A Single Polymorphic Locus, Termed The

Cloning and characterization of cDNAs encoding S-RNases from almond (Prunus dulcis): primary structural features and sequence diversity of the S-RNases in Rosaceae

Molecular and General Genetics MGG, 1998
cDNAs encoding three S-RNases of almond (Prunus dulcis), which belongs to the family Rosaceae, were cloned and sequenced. The comparison of amino acid sequences between the S-RNases of almond and those of other rosaceous species showed that the amino acid sequences of the rosaceous S-RNases are highly divergent, and intra-subfamilial similarities are ...

Identification of the pollen determinant of S-RNase-mediated self-incompatibility

Nature, 2004
Many flowering plants have adopted self-incompatibility mechanisms to prevent inbreeding and promote out-crosses. In the Solanaceae, Rosaceae and Scrophulariaceae, two separate genes at the highly polymorphic S-locus control self-incompatibility interactions: the S-RNase gene encodes the pistil determinant and the previously unidentified S-gene encodes

S-RNase uptake by compatible pollen tubes in gametophytic self-incompatibility

Nature, 2000
Many flowering plants avoid inbreeding through a genetic mechanism termed self-incompatibility. An extremely polymorphic S-locus controls the gametophytic self-incompatibility system that causes pollen rejection (that is, active arrest of pollen tube growth inside the style) when an S-allele carried by haploid pollen matches one of the S-alleles ...

Comparing Models For S-Rnase-Based Self-Incompatibility

2008
S-Rnase-Based Self-Incompatibility (Si) Is Known To Occur In Three Families Of Flowering Plants: Solanaceae, Rosaceae And Plantaginaceae. It Is The Most Widely Distributed Si System Described So Far. It Is A Single-Locus Gametophytic System. Gene Pairs At The S-Locus Determine S-Specificity On The Pistil And The Pollen Sides Of Si.
