EXO70A1 — Brassica oleracea

Summary

BoEXO70A1 (BOLC102_C09P076550.1) on cabbage chromosome 9 encodes a member of the Exo70 protein family, containing Exo70_C and cullin-repeat-like domains, and is annotated with acetylase activity, including H3 histone acetylase activity, as well as DNA and protein binding and phosphatidylinositol-4,5-bisphosphate binding. The gene is associated with exocyst and exosome localization, pollen tube tip and cell plate targeting, and is linked to processes including pollen acceptance, tube development, protoxylem and xylem vessel differentiation, seed coat development, mucilage anabolism, lateral root morphogenesis, and regulation of secondary cell wall biogenesis. It is associated with traits such as self-incompatibility, leaf trichome density, flowering time, lateral root number and length, anthocyanin content, and responses to biotic stress, light intensity, and plant nutrients. Studies of related genes in other species connect the family to polarized exocytosis, pollen-pistil compatibility, polar auxin transport, and root epidermal patterning.
