PYL8 mediates ABA perception in the root through non-cell-autonomous and ligand-stabilization–based mechanisms (2018)
Journal Article
Belda-Palazon, B., Gonzalez-Garcia, M., Lozano-Juste, J., Coego, A., Antoni, R., Julian, J., …Rodriguez, P. L. (2018). PYL8 mediates ABA perception in the root through non-cell-autonomous and ligand-stabilization–based mechanisms.

The phytohormone abscisic acid (ABA) plays a key role regulating root growth, root system architecture, and root adaptive responses, such as hydrotropism. The molecular and cellular mechanism...

Hydrotropism: how roots search for water (2018)
Journal Article
Dietrich, D. (2018). Hydrotropism: how roots search for water. Journal of Experimental Botany, 69(11), 2759-2771. https://doi.org/10.1093/jxb/ery034

Fresh water is an increasingly scarce resource for agriculture. Plant roots mediate water uptake from the soil and have developed a number of adaptive traits such as hydrotropism to aid water foraging. Hydrotropism modifies root growth to respond to...

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. (2017). Root hydrotropism is controlled via a cortex-specific growth mechanism. Nature Plants, 3(6), Article 17057. https://doi.org/10.1038/nplants.2017.57

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...

Plant biology: building barriers... in roots (2017)
Journal Article
van Wangenheim, D., Goh, T., Dietrich, D., & Bennett, M. J. (2017). Plant biology: building barriers... in roots. Current Biology, 27(5), R172-R174. https://doi.org/10.1016/j.cub.2017.01.060

The Casparian strip is an important barrier regulating water and nutrient uptake into root tissues. New research reveals two peptide signals and their co-receptors play critical roles patterning and maintaining barrier integrity.

Hydrotropism: analysis of the root response to a moisture gradient (2016)
Journal Article
Antoni, R., Dietrich, D., Bennett, M. J., & Rodriguez, P. L. (2016). Hydrotropism: analysis of the root response to a moisture gradient. Methods in Molecular Biology, 1398, 3-9. https://doi.org/10.1007/978-1-4939-3356-3_1

Hydrotropism is a genuine response of roots to a moisture gradient to avoid drought. An experimental system for the induction of hydrotropic root response in petri dishes was designed by pioneering groups in the field. This system uses split agar pla...
