Class III pistil-specific extensin-like proteins from tobacco have characteristics of arabinogalactan proteins.
Class III pistil-specific extensin-like proteins (PELPIII) are specifically localized in the intercellular matrix of tobacco (Nicotiana tabacum) styles. After pollination the majority of PELPIII are translocated into the callosic layer and the callose plugs of the pollen tubes, which could suggest a function of PELPIII in pollen tube growth. PELPIII may represent one of the chemical and/or phys...
متن کاملRestoring pistil-side self-incompatibility factors recapitulates an interspecific reproductive barrier between tomato species.
Interspecific reproductive barriers are poorly understood, but are central to the biological species concept. The pre-zygotic barriers between red- and green-fruited species in the tomato clade of the genus Solanum provide a model to better understand these barriers in plants. Compatibility usually follows the SI x SC rule: pollen from self-compatible (SC) red-fruited species is rejected on pis...
متن کاملSelf-incompatibility and other pollen-pistil interactions.
Self-incompatibility allows plants to recognize and reject pollen from the same plant, thereby reducing inbreeding. Although in most cases self-incompatibility is controlled by a single genetic locus, recent results show that surprisingly complex signal transduction pathways and many players are involved in pollen recognition and rejection.
متن کاملSelf-incompatibility in Brassicaceae crops: lessons for interspecific incompatibility
Most wild plants and some crops of the Brassicaceae express self-incompatibility, which is a mechanism that allows stigmas to recognize and discriminate against "self" pollen, thus preventing self-fertilization and inbreeding. Self-incompatibility in this family is controlled by a single S locus containing two multiallelic genes that encode the stigma-expressed S-locus receptor kinase and its p...
