HSP70 — Solanum tuberosum

Summary

PGSC0003DMG400027793, designated StHSP70 on potato chromosome 11, encodes a protein belonging to the UPF0220 family. The gene is associated with diverse biological processes including endosome-to-vacuole transport via the MVB sorting pathway, chlorophyll breakdown, proline metabolism, sterol and fatty acid anabolism, sucrose metabolism, detoxification, immune response, jasmonic acid signaling, virus-induced PTGS, nitric oxide storage, cell division, nucleosome assembly, and response to heat. It is linked to membrane localisation and to traits such as plant height, fresh and dry root weight, plant fresh weight, net photosynthetic rate, hydrogen peroxide content, and proline content. Studies of related genes in other species connect the family to drought tolerance, chlorophyll content, seed weight and size, fruit size, germination rate, leaf shape, and stomatal resistance.
