KOM — Asparagus officinalis

Summary

A4U43_C04F30970 (KOM) on asparagus chromosome 4 encodes a rhomboid-family serine-type endopeptidase (EC 3.4.21.105). The gene is associated with pollen wall assembly, proteolysis, and localisation to the endomembrane system, endoplasmic reticulum, Golgi complex, plasmodesmata, membrane, mitochondria, cytoplasm, and nucleus. It is linked to pollen wall development, callose accumulation, pollen-stigma adhesion, and hypoxia tolerance. Related genes in other species link the rhomboid family to proteolytic activity and altered pollen exine wall morphology, while broader sequence similarity connects the family to flower morphology, root architecture, fertility, and seed dormancy.
