TT1 — Oryza sativa Indica Group

Summary

BGIOSGA026895 (TT1, also known as PAB1) on chromosome 8 of Indica rice encodes a protein with proteasome alpha-type domains and N-terminal nucleophile hydrolase features, annotated with catalytic activity on nucleic acids, ATP hydrolase activity, protein binding, and as a structural constituent of the ribosome. The gene is associated with the proteasome core complex, cytosol, mitochondria, and plasmalemma. It is linked to stress, zinc sensitivity, heat tolerance, herbicide sensitivity, disease tolerance, and traits including spikelet fertility, root length, leaf composition, inflorescence morphology, and meristem development. Biological process associations encompass meristem growth, root morphogenesis, phyllome and inflorescence development, male and female gamete generation, innate immunity, ubiquitin-dependent proteolysis, and response to misfolded proteins. Studies of related genes in other species link the family to zinc deficiency tolerance.
