SUC1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0419590 (HvSUC1) on barley chromosome 5H encodes a protein with sucrose:proton symporter activity and belongs to the sucrose symporter family and the major facilitator superfamily. The gene is associated with phloem sucrose loading, glucoside and maltose transport, and carbohydrate membrane transport. It has been linked to grain yield, grain filling, grain size, seed dormancy, sucrose content, photosynthetic rate, and abiotic stress responses. Additional associations include plant growth and development, root morphology, cell cycle traits, and auxin sensitivity. Studies of related genes in other species link the family to phloem loading, carbon partitioning, plant growth, grain-filling, and grain number.
