Journal Article
Orosa Puente, B., Leftley, N., Von Wangenheim, D., Banda, J., Anjil, S., Hill, K., …Bennett, M. (2018). Roots branch towards water by post-translational modification of transcription factor ARF7. 00 Journal not listed, 362(6421), 1407-1410. doi:10.1126/science.aau3956

Plants adapt to heterogeneous soil conditions by altering their root architecture. For example, roots branch when in contact with water using the hydropatterning response. We report that hydropatterning is dependent on auxin response factor ARF7. Thi... Read More
