DOI: 10.1007/s00709-017-1158-0
Abstract: Ethylene and cGMP are key regulators of plant developmental processes. In this study, we demonstrate that ethylene or cGMP promote pollen tube growth in a dose-dependent manner. The etr1–1 mutant was found to be insensitive… read more here.

DOI: 10.1016/j.molp.2018.07.004
Abstract: Double fertilization in angiosperms requires the targeted delivery of immotile sperm to the eggs through pollen tubes. The polarity of tip-growing pollen tubes is maintained through dynamic association of active Rho GTPases of plants (ROP-GTP)… read more here.

DOI: 10.1016/j.scienta.2018.06.081
Abstract: Abstract 5-Aminolevunic acid, a natural plant growth regulator, can thin pear fruits by inhibiting pollen tube growth through Ca2+-ATPase-mediated Ca2+ efflux. Here, using a non-invasive micromeasurement technology, we detected the occurrence of an ALA-induced Ca2+… read more here.

DOI: 10.1093/plphys/kiad208
Abstract: S-RNase-mediated self-incompatibility (SI) prevents self-fertilization and promotes outbreeding to ensure genetic diversity in many flowering plants, including pear (Pyrus sp.). Brassinosteroids (BRs) have well-documented functions in cell elongation, but their molecular mechanisms in pollen tube… read more here.

DOI: 10.1104/pp.17.01722
Abstract: The dynamic organization of vacuoles and the association of tonoplast cargo protein PAT10 are impaired and lead to reduced pollen tube growth in adaptor protein-3 mutants. Pollen tube growth is an essential step for successful… read more here.
