APK1 — Brassica oleracea

Summary

BoAPK1 (BOLC102_C05P005710.1) on cabbage chromosome 5 encodes a plant serine/threonine protein kinase with ATP-binding and protein homodimerization activities. This gene is associated with diverse biological processes including tropism, glutathione and glucosinolate anabolism, regeneration, sepal giant cell differentiation, flower morphogenesis, regulation of asymmetric cell division, and plant organ development. It is linked to innate immune response signaling, detection and response to fungal molecules, hypersensitive response-programmed cell death, and upregulation of reactive oxygen species anabolism. Localization evidence links the product to the plasma membrane, mitochondrial membrane, and multivesicular body membrane. The gene is also associated with root branching traits. Related genes in other species link the broader APK1/PBL9 kinase family to photochemical quenching and root morphology traits.
