TaARF4 genes are linked to root growth and plant height in wheat

Background and Aims Auxin response factors (ARFs) as transcription activators or repressors have important roles in plant growth and development, but knowledge about the functions of wheat ARF members is limited. A novel ARF member in wheat (Triticum aestivum), TaARF4, was identified, and its protein function, haplotype geographic distribution and allelic frequencies were investigated. Methods Tissue expression of TaARF4 was analysed by...
