PEUP2 — Brassica oleracea var. botrytis

Summary

BoPEUP2 (PEUP2, also known as BoATG18A) on cauliflower chromosome 8 encodes a PROPPIN family protein containing WD40 repeats. The gene product localises to the cytosol and nucleus and is associated with protein binding. BoPEUP2 has been linked to the regulation and positive regulation of autophagy, leaf senescence, nuclear export, and responses to starvation, oxidative stress, osmotic and salinity stress, thirst, and defence against fungi. Phenotype associations include autophagy, cell death, protein degradation, peroxisome degradation, powdery mildew resistance, resistance to necrotrophic fungal pathogens such as Botrytis cinerea, and restored IBA responsiveness. Related genes in other species are associated with nutrient starvation tolerance, salt tolerance, oxidative stress tolerance, fungal pathogen resistance, pexophagy, hydrotropic response, and senescence.
