BTS — Sorghum bicolor
Summary
SORBI_3008G117200 (SbBTS) encodes a RING-type zinc finger protein with Znf_CTCHY, Znf_CHY and Znf_RING domains, and exhibits ubiquitin ligase activity, DNA-binding transcription factor activity, and iron binding. This sorghum gene on chromosome 8 is associated with cellular and multicellular iron homeostasis, iron import, response to iron starvation, regulation of iron transport, and proteasomal ubiquitin-dependent protein catabolism. It is linked to glucose-mediated signaling, regulation of stomatal opening, and inhibition of defense response to bacteria. Associations with grain yield, chlorophyll content, leaf necrosis, root branching, auxin sensitivity, and disease tolerance have been noted. The gene product localizes to both the cytoplasm and nucleus. Studies of related genes in other species connect the family to iron and zinc homeostasis, stress tolerance, and grain nutrient content.
