Arabinogalactan proteins as molecular markers in Arabidopsis thaliana sexual reproduction.
Some of the most important changes that occur in plants during sexual reproduction involve the transition from a sporophytic to a gametophytic type of development. In this paper, these changes were evaluated for Arabidopsis thaliana. The results obtained clearly show differences in the pattern of distribution of specific arabinogalactan protein (AGP) sugar epitopes, during anther and ovule deve...
متن کاملCharacterization of a pollen-specific agp1-like protein in Arabidopsis thaliana
Article history: Received on: 16/05/2016 Revised on: 10/06/2016 Accepted on: 20/06/2016 Available online: 05/11/2016 In plants, pollen tube germination occurs widely in flowering plants. In Arabidopsis thaliana, it has been reported ARABINOGALACTAN PROTEIN 1 (AGP1) plays an important role in pollen tube germination. The expression of arabinogalactan protein in Arabidopsis pollen tubes has been ...
متن کاملKNS4/UPEX1: A Type II Arabinogalactan β-(1,3)-Galactosyltransferase Required for Pollen Exine Development.
Pollen exine is essential for protection from the environment of the male gametes of seed-producing plants, but its assembly and composition remain poorly understood. We previously characterized Arabidopsis (Arabidopsis thaliana) mutants with abnormal pollen exine structure and morphology that we named kaonashi (kns). Here we describe the identification of the causal gene of kns4 that was found...
متن کاملRole of Glycosyltransferases in Pollen Wall Primexine Formation and Exine Patterning1[OPEN]
The pollen cell wall is important for protection of male sperm from physical stresses and consists of an inner gametophytederived intine layer and a sporophyte-derived exine layer. The polymeric constituents of the robust exine are termed sporopollenin. The mechanisms by which sporopollenin is anchored onto microspores and polymerized in specific patterns are unknown, but the primexine, a trans...
