Functional Characterization of <i>PeVLN4</i> Involved in Regulating Pollen Tube Growth from Passion Fruit.

ABSTRACT: Passion fruit (Passiflora edulis), mainly distributed in tropical and subtropical regions, is popular for its unique flavor and health benefits. The actin cytoskeleton plays a crucial role in plant growth and development, and villin is a key regulator of actin dynamics. However, the mechanism underlying the actin filament regulation of reproductive development in passion fruit remains poorly understood. Here, we characterized a villin isovariant in passion fruit, Passiflora edulis VLN4 (PeVLN4), highly and preferentially expressed in pollen. Subcellular localization analysis showed that PeVLN4 decorated distinct filamentous structures in pollen tubes. We next introduced PeVLN4 into Arabidopsis villin mutants to explore its functions on the growing pollen
