The adhesion of pollen grains to the stigma is the first step of pollination in flowering plants. During this step, stigmas discriminate between pollen grains that can and cannot be permitted to effect fertilization. This selection is operated by various constituents of the cell walls of both partners. Several genes structurally related to the(More)
The Arabidopsis genome contains many sequences annotated as encoding H(+)-coupled cotransporters. Among those are the members of the cation:proton antiporter-2 (CPA2) family (or CHX family), predicted to encode Na(+),K(+)/H(+) antiporters. AtCHX17, a member of the CPA2 family, was selected for expression studies, and phenotypic analysis of knockout mutants(More)
The enzymatically synthesized thiol peptide phytochelatin (PC) plays a central role in heavy metal tolerance and detoxification in plants. In response to heavy metal exposure, the constitutively expressed phytochelatin synthase enzyme (PCS) is activated leading to synthesis of PCs in the cytosol. Recent attempts to increase plant metal accumulation and(More)
Expression of a mycorrhizal fungal-specific phosphate (P) transporter gene (HcPT1) was studied in mycelium of the ectomycorrhizal fungus Hebeloma cylindrosporum, by in situ reverse transcriptase polymerase chain reaction using amplification of complementary DNA sequences. The expression of HcPT1 was visualised under two different P treatments. Mycelium was(More)
Aquaporins are channel proteins present in the plasma membrane and most of intracellular compartments of plant cells. This review focuses on recent insights into the cellular function of plant aquaporins, with an emphasis on the subfamily of Plasma membrane Intrinsic Proteins (PIPs). Whereas PIPs mostly serve as water channels, novel functions associated(More)
Rice production faces the challenge to be enhanced by 50% by year 2030 to meet the growth of the population in rice-eating countries. Whereas yield of cereal crops tend to reach plateaus and a yield is likely to be deeply affected by climate instability and resource scarcity in the coming decades, building rice cultivars harboring root systems that can(More)
