CEVI57 — Solanum tuberosum

Summary

PGSC0003DMG400004548 (symbol CEVI57) on potato chromosome 3 encodes a proteinase inhibitor type-2 CEVI57, a member of the protease inhibitor I20 family, with serine-type endopeptidase inhibitor activity. The gene is associated with downregulation of photosynthesis, phytoalexin biosynthesis, induced systemic resistance, auxin transport, cytokinin signaling, and phloem transport. It is also linked to hormone and sterol anabolism, the MVA pathway, starch metabolism, protein stabilization, and post-translational modification. The encoded product localizes to the extracellular space. CEVI57 is associated with potassium concentration, seed weight, germination rate, and plant height. Related genes in other species connect the family to salt tolerance.
