ETT — Arabidopsis thaliana

Summary

AT2G33860 (ETT, also known as ARF3 or ETTIN) encodes a protein with an ARF domain, a B3 DNA-binding domain, and a DNA-binding pseudobarrel superfamily domain, and is associated with chromatin DNA binding, transcription cis-regulatory region binding, DNA binding transcription factor activity, and small molecule binding. This gene is linked to auxin signalling, lateral root emergence and development, and the regulation of seed size and seed development. In Arabidopsis, ETT has been observed to influence male and female gametophyte development, and is associated with style and stigma development, carpel identity specification, stamen formation, and floral organ number and identity. It is also connected to leaf formation, abaxial cell fate specification, phyllotaxy, and organ patterning. The gene has been linked to seed coat pattern and colour, pollen fertility, and auxin sensitivity. Studies of related genes in other species connect the family to traits such as drought tolerance, water use efficiency, plant height, root length, and chlorophyll content.
