Transcriptome analysis reveals the same 17 S-locus F-box genes in two haplotypes of the self-incompatibility locus of Petunia inflata.
Petunia possesses self-incompatibility, by which pistils reject self-pollen but accept non-self-pollen for fertilization. Self-/non-self-recognition between pollen and pistil is regulated by the pistil-specific S-RNase gene and by multiple pollen-specific S-locus F-box (SLF) genes. To date, 10 SLF genes have been identified by various methods, and seven have been shown to be involved in pollen ...
متن کاملInsight into S-RNase-based self-incompatibility in Petunia: recent findings and future directions
S-RNase-based self-incompatibility in Petunia is a self/non-self recognition system that allows the pistil to reject self-pollen to prevent inbreeding and to accept non-self pollen for outcrossing. Cloning of S-RNase in 1986 marked the beginning of nearly three decades of intensive research into the mechanism of this complex system. S-RNase was shown to be the sole female determinant in 1994, a...
متن کاملSelf-incompatibility in Petunia inflata: the relationship between a self-incompatibility locus F-box protein and its non-self S-RNases.
The highly polymorphic S (for self-incompatibility) locus regulates self-incompatibility in Petunia inflata; the S-RNase regulates pistil specificity, and multiple S-locus F-box (SLF) genes regulate pollen specificity. The collaborative non-self recognition model predicts that, for any S-haplotype, an unknown number of SLFs collectively recognize all non-self S-RNases to mediate their ubiquitin...
متن کاملFour previously identified Petunia inflata S-locus F-box genes are involved in pollen specificity in self-incompatibility.
Dear Editor, Petunia possesses self-incompatibility (SI), by which pistils reject self-pollen but accept non-self pollen for fertilization (de Nettancourt, 2001; Iwano and Takayama, 2012). Genes that regulate self/non-self recognition between pollen and pistil are located at the highly polymorphic S-locus. An S-haplotype contains the pistil-specific S-RNase gene that regulates pistil specificit...
متن کاملIdentification of a Skp1-Like Protein Interacting with SFB, the Pollen S Determinant of the Gametophytic Self-Incompatibility in Prunus1[W]
Many species in Rosaceae, Solanaceae, and Plantaginaceae exhibit S-RNase-based self-incompatibility (SI). In this system, the pistil and pollen specificities are determined by S-RNase and the S locus F-box protein, respectively. The pollen S determinant F-box protein in Prunus (Rosaceae) is referred to by two different terms, SFB (for S-haplotype-specific F-box protein) and SLF (for S locus F b...
