AOS — Solanum lycopersicum

Summary

SOLYC04G079730.1, the tomato AOS gene on chromosome 4, encodes allene oxide synthase, a cytochrome P450 enzyme with allene oxide synthase, colneleate synthase, allene-oxide cyclase and hydro-lyase activities. The protein localises to the chloroplast membrane, thylakoid and envelope. In tomato, AOS2 is associated with cold tolerance. The gene is linked to oxylipin and jasmonate biosynthesis, and to the lipoxygenase and epoxygenase P450 pathways. Associations include fruit size, grain size, relative yield, carotenoid content, chlorophyll content, photosynthetic rate, stomatal resistance and opening, leaf curling, root length, shoot fresh weight, and responses to abiotic stress, oxidative stress, low temperature, salt, boron and sorbitol. It is also connected to fungal resistance, virus resistance, defense against herbivory and necrotrophic fungi, male sterility, anther dehiscence, nectar production, sepal senescence and cell death.
