Could the transcription factor HHO5 hold the key to breaking fertilizer dependency?
Plant Science Research WeeklyEfficient nitrogen uptake is essential for plant growth. Hinckley et al. have characterized HRS1 HOMOLOG 5 (HHO5), a transcription factor in Arabidopsis that had been previously overlooked compared to the NIGT1 family. Through a single T-DNA insertion mutation, the authors show HHO5 acts as a non-redundant…
