Evolution of the thermostability of actin-depolymerizing factors enhances pollen germination at high temperature
In angiosperms, pollen germination leads to a period of extensive polarized growth of the pollen tube, which carries the sperm nuclei to the ovule. Studies of tip growth in both pollen tubes and root hairs have contributed to a descriptive model that involves polarized vesicle movement along the cytoskeleton to release materials needed for growth, […]
