physiological function | pollen from mutants lacking expression of the peroxisomal-encoding AtPAO3 gene, is unable to induce the opening of the Ca2+-permeable channels in the presence of spermidine, resulting in reduced pollen tube growth and seed number. A high spermidine concentration triggers a Ca2+ influx beyond the optimal, which has adeleterious effect | Arabidopsis thaliana |
