Mobile PEAR transcription factors integrate positional cues to prime cambial growth (2019)
Journal Article
Miyashima, S., Roszak, P., Sevilem, I., Toyokura, K., Blob, B., Heo, J., …Helariutta, Y. (2019). Mobile PEAR transcription factors integrate positional cues to prime cambial growth. Nature, doi:10.1038/s41586-018-0839-y

Apical growth in plants initiates upon seed germination, whereas radial growth is primed only during early ontogenesis in procambium cells and activated later by the vascular cambium1. Although it is not known how radial growth is organized and regul... Read More

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

Cellular patterning of Arabidopsis roots under low phosphate conditions (2018)
Journal Article
Janes, G., von Wangenheim, D., Cowling, S., Kerr, I. D., Band, L. R., French, A. P., & Bishopp, A. (2018). Cellular patterning of Arabidopsis roots under low phosphate conditions. Frontiers in Plant Science, doi:10.3389/fpls.2018.00735. ISSN 1664-462X

Phosphorus is a crucial macronutrient for plants playing a critical role in many cellular signaling and energy cycling processes. In light of this, phosphorus acquisition efficiency is an important target trait for crop improvement, but it also provi... 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

Theoretical approaches to understanding root vascular patterning: a consensus between recent models (2016)
Journal Article
Mellor, N., Adibi, M., El-Showk, S., De Rybel, B., King, J., Mähönen, A. P., …Bishopp, A. (in press). Theoretical approaches to understanding root vascular patterning: a consensus between recent models. Journal of Experimental Botany, doi:10.1093/jxb/erw410. ISSN 0022-0957

The root vascular tissues provide an excellent system for studying organ patterning, as the specification of these tissues signals a transition from radial symmetry to bisymmetric patterns. The patterning process is controlled by the combined action... Read More

Lateral root emergence in Arabidopsisis dependent on transcription factor LBD29 regulation of auxin influx carrier LAX3 (2016)
Journal Article
Porco, S., Larrieu, A., Du, Y., Gaudinier, A., Goh, T., Swarup, K., …Bennett, M. J. (2016). Lateral root emergence in Arabidopsisis dependent on transcription factor LBD29 regulation of auxin influx carrier LAX3. Development, 143(18), doi:10.1242/dev.136283. ISSN 0950-1991

Lateral root primordia (LRP) originate from pericycle stem cells located deep within parental root tissues. LRP emerge through overlying root tissues by inducing auxin-dependent cell separation and hydraulic changes in adjacent cells. The auxin-induc... Read More
