Function
MLO7 Antibody is potentially involved in the modulation of pathogen defense and leaf cell death. Its activity appears to be regulated by Ca(2+)-dependent calmodulin binding and may not require heterotrimeric G proteins. This antibody plays a crucial role in controlling pollen tube reception in the female gametophyte synergids.
Gene References Into Functions
- MLO7 plays a critical role in pollen tube reception, dependent on its localization within synergids into a Golgi-associated compartment before pollen tube arrival. This indicates that pollen tube-triggered regulation of the synergid secretory system is crucial for synergid function during pollination. PMID: 28724621
- Research suggests that pollen tube (PT) reception and powdery mildew (PM) infection share molecular components. NTA, discovered in the context of PM resistance, and FERONIA control PT reception. Notably, fer mutants also exhibit PM resistance, revealing a new function for FER. PMID: 21071669
Protein Families
MLO family
Subcellular Location
Cell membrane; Multi-pass membrane protein. Endomembrane system. Note=In synergids of unfertilized mature female gametophytes, present in a punctate pattern of endomembranes throughout the cytoplasm. Become polarly localized to the basal half of the synergids, to the filiform apparatus, upon pollen tube arrival at the micropyle. This relocalization upon fertilization requires FER.
Tissue Specificity
Restricted to pollen, synergids, pistils and immature anthers. Also detected in seedlings, leaves, stems and inflorescens.
