BAK1 — Solanum tuberosum

Summary

PGSC0003DMG400028112, the potato BAK1 gene on chromosome 10, encodes a leucine-rich repeat (LRR) protein with transmembrane receptor serine/threonine kinase activity and coreceptor activity. It is associated with immune complex formation, innate immunity, detection of symbiotic fungi, regulation of defence response to fungi, upregulation of the innate immune response, positive regulation of the hypersensitive response, and the MAPK cascade. The gene is also linked to tissue morphogenesis, somatic embryogenesis, cell differentiation, cell death, hormone anabolism, metabolic burst, and virus-induced post-transcriptional gene silencing. Its product localizes to the plasma membrane, early and late endosome membranes, cytoplasm, mitochondria, and extracellular space. Studies of related genes in other species connect the BAK1 family to leaf necrosis, bacterial disease response, plant height, stem elongation, and chlorophyll content.
