Aquaporins in Arabidopsis thaliana are involved in water movement within the plant, facilitating its transport across cell membranes, which is essential for multiple biological processes. In this context, aquaporins participate in the regulation of pollen grain turgor, a key aspect for its germination and the growth of the pollen tube. Alterations in these proteins can lead to changes in pollen development, potentially affecting plant fertility. It has also been suggested that aquaporins may be involved in guiding the pollen tube toward the ovule, responding to humidity gradients. Therefore, aquaporins are vital for pollen development and, ultimately, for the successful reproduction of the plant. Throughout my professional career at the Institute of Agrobiotechnology Research (CIALE) in Salamanca, Spain, I had the opportunity to participate in projects aimed at studying the role of aquaporins in the development of pollen grains and the pollen tube in Arabidopsis thaliana. During this project, we studied how aquaporins facilitate water passage across cell membranes, a crucial process for regulating turgor and pollen viability. By studying various mutations, we observed that changes in these proteins significantly affect plant fertility. Staining methods, such as DAPI and aniline, were used to measure pollen progression and fertilization, revealing differences among the analyzed genotypes. The results obtained in this study highlight the importance of aquaporins, particularly certain isoforms, in the proper development of pollen and the pollen tube, providing new opportunities to explore their role in plant biology.
