Roots branch towards water by post-translational modification of transcription factor ARF7 (2018)
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

A mechanistic framework for auxin dependent Arabidopsis root hair elongation to low external phosphate (2018)
Journal Article
Bhosale, R., Giri, J., Pandey, B. K., Giehl, R. F., Hartmann, A., Traini, R., …Swarup, R. (in press). A mechanistic framework for auxin dependent Arabidopsis root hair elongation to low external phosphate. Nature Communications, 9(1), doi:10.1038/s41467-018-03851-3. ISSN 2041-1723

Phosphate (P) is an essential macronutrient for plant growth. Roots employ adaptive mechanisms to forage for P in soil. Root hair elongation is particularly important since P is immobile. Here we report that auxin plays a critical role promoting root... Read More

Rice auxin influx carrier OsAUX1 facilitates root hair elongation in response to low external phosphate (2018)
Journal Article
Giri, J., Bhosale, R., Huang, G., Pandey, B. K., Parker, H., Zappala, S., …Bennett, M. J. (in press). Rice auxin influx carrier OsAUX1 facilitates root hair elongation in response to low external phosphate. Nature Communications, 9(1), doi:10.1038/s41467-018-03850-4

Root traits such as root angle and hair length influence resource acquisition particularly for immobile nutrients like phosphorus (P). Here, we attempted to modify root angle in rice by disrupting the OsAUX1 auxin influx transporter gene in an effort... Read More

Root hydrotropism is controlled via a cortex-specific growth mechanism (2017)
Journal Article
Dietrich, D., Pang, L., Kobayashi, A., Fozard, J. A., Boudolf, V., Bhosale, R., …Bennett, M. J. (in press). Root hydrotropism is controlled via a cortex-specific growth mechanism. Nature Plants, 3, doi:10.1038/nplants.2017.57. ISSN 2055-026X

Plants can acclimate by using tropisms to link the direction of growth to environmental conditions. Hydrotropism allows roots to forage for water, a process known to depend on abscisic acid (ABA) but whose molecular and cellular basis remains unclear... Read More

Dioxygenase-encoding AtDAO1 gene controls IAA oxidation and homeostasis in Arabidopsis (2016)
Journal Article
Porco, S., Pěnčík, A., Rashed, A., Voss, U., Casanova-Sáez, R., Bishopp, A., …Ljung, K. (2016). Dioxygenase-encoding AtDAO1 gene controls IAA oxidation and homeostasis in Arabidopsis. Proceedings of the National Academy of Sciences, 113(39), doi:10.1073/pnas.1604375113. ISSN 1091-6490

Auxin represents a key signal in plants, regulating almost every aspect of their growth and development. Major breakthroughs have been made dissecting the molecular basis of auxin transport, perception, and response. In contrast, how plants control t... Read More
