MLO — Capsicum annuum

Summary

T459_05104, the pepper (Capsicum annuum) MLO gene on chromosome 2, encodes a calmodulin-binding membrane protein with predicted localisation at the plasmalemma, plasmodesmata, Golgi complex, mitochondria and extracellular space. The gene is associated with defence responses to fungi and bacteria, cell death, downregulation of defence response, virus-induced post-transcriptional gene silencing, and regeneration. It has been connected to Botrytis cinerea resistance, leaf senescence, callose deposition, systemic acquired resistance and callus induction. Studies of related MLO family members in other species link the family to powdery mildew resistance and susceptibility, bacterial wilt susceptibility, heat tolerance, ozone tolerance, oomycete resistance, non-host resistance to Magnaporthe oryzae, and traits including water use efficiency, seed maturation, seed dormancy, leaf senescence, stomatal resistance, root morphology and high temperature stress response.
