Abstract excerpt
The Arabidopsis gene BIG (formerly DOC1/TIR3/UMB1/ASA1) is known to encode a huge calossin-like protein that is required for polar auxin transport (PAT). Mutations at this locus, in addition to reducing PAT, can alter the sensitivity of plants to several hormones and light. The tir3-1 allele of BIG reduces the response of plants to application of the gibberellin (GA) precursors ent-kaurenoic acid and GA12 and its...
