The underground life of homeodomain-leucine zipper transcription factors

Abstract Roots are the anchorage organs of plants, responsible for water and nutrient uptake, exhibiting high plasticity. Root architecture is driven by interactions biomolecules, including transcription factors hormones that crucial players regulating root Multiple factor families involved in development; some, such as ARFs LBDs, have been well characterized, whereas others remain less investigated. In this review, we synthesize current knowledge about involvement large family homeodomain-leucine zipper (HD-Zip) development. This divided into four subfamilies (I–IV), mainly according to structural features, additional motifs aside from HD-Zip, their size, gene structure, expression patterns. We explored analyzed public databases scientific literature regarding HD-Zip Arabidopsis other species. Most members expressed specific cell types several individuals each group assigned functions Notably, a proportion studied proteins part intricate regulation pathways primary lateral growth
