The Arabidopsis EDT1/HDG11,encoding a homeodomain-START transcription factor,was previously demonstrated to confer improved drought resistance and increased biomass when overexpressed in the Arabidopsis and transgenic tobacco(Yu et al.,2008).We also showed that overexpression of the dicot AtHDG11 in either monocot rice or woody plants cotton and poplar also confers similar phenotypes to those observed in edt1 and transgenic tobacco,which include enhanced drought resistance,improved root system,reduced stomatal density,increased photosynthesis,water use efficiency,and yield(Yu et al.,2013; Yu et al.,2015).Here we report the mechanisms by which EDT1 improves root system architecture in edt1.
