PRK3 — Cicer arietinum
Summary
CaPRK3 (LOC101493888) on chickpea chromosome 1 encodes a protein with a kinase domain and belongs to the PRK1-6/SRF4-like family. It is associated with pollen tube guidance, pollen germination and maturation, megasporogenesis, microsporogenesis, and anther wall tapetum development. The gene product localises to the pollen tube tip, apical plasma membrane, endosome, and plasmodesma. CaPRK3 is linked to traits including days to maturity, harvest index, seed weight, chlorophyll content, and cell membrane stability. It is associated with defence responses to fungi, upregulation of innate immune response, detection of brassinosteroid stimulus, hormone-mediated signalling, and skotomorphogenesis. Related genes in other species are linked to pollen tube growth and species-preferential micropylar pollen tube guidance.
