Coordinated plasticity maintains hydraulic safety in sunflower leaves

Cardoso AA, Brodribb TJ, Lucani CJ, DaMatta FM, McAdam SAM. Coordinated plasticity maintains hydraulic safety in sunflower leaves. Plant Cell Environ. 2018. https://doi.org/10.1111/pce.13335

The air‐seeding threshold water potential establishes a hydraulic limit on the ability of woody species to survive in water‐limiting environments, but herbs may be more plastic in terms of their ability to adapt to drying conditions. Here we…

Does ozone increase ABA levels by non‐enzymatic synthesis causing stomata to close?

McAdam EL, Brodribb TJ, McAdam SAM (2017)Does ozone increase ABA levels by non‐enzymatic synthesis causing stomata to close? Plant, Cell and Environment 40: 741-747

Reactive oxygen species (ROS) are widely recognized as important regulators of stomatal aperture and plant gas exchange. The pathways through which stomata perceive ROS share many commonlinkages with the well characterized signalling pathway for the hormone abscisic acid…

Xylem and Stomata, Coordinated Through Time and Space

Land plants exhibit a degree of homeostasis in leaf water content to protect against damage to photosynthetic and xylem tissues, and to maintain an efficient allocation of resources. This is achieved by a strong coordination between the systems…

Shoot-derived abscisic acid promotes root growth

McAdam, S. A. M., Brodribb, T. J., and Ross, J. J. (2016) Shoot-derived abscisic acid promotes root growth. Plant, Cell and Environment, 39: 652–659. doi: 10.1111/pce.12669.

The phytohormone abscisic acid (ABA) plays a major role in regulating root growth. Most work to date has investigated the influence of root-sourced ABA on root growth during wa- ter stress. Here, we tested whether foliage-derived ABA could…

Hormonal dynamics contributes to divergence in seasonal stomatal behaviour in a monsoonal plant community

MCADAM, S. A.M. and BRODRIBB, T. J. (2015), Hormonal dynamics contributes to divergence in seasonal stomatal behaviour in a monsoonal plant community. Plant Cell Environ, 38: 423–432. doi:10.1111/pce.12398

The plant hormone abscisic acid (ABA) is a primary regulator of plant transpiration, but its influence in determining seasonal stomatal behaviour in natural plant communities is poorly understood. We examined distantly related vascular plants growing together in a…

Are needles of Pinus pinaster more vulnerable to xylem embolism than branches? New insights from X‐ray computed tomography

Bouche, P. S., Delzon, S., Choat, B., Badel, E., Brodribb, T. J., Burlett, R., Cochard, H., Charra-Vaskou, K., Lavigne, B., Li, S., Mayr, S., Morris, H., Torres-Ruiz, J. M., Zufferey, V., and Jansen, S. (2016) Are needles of Pinus pinaster more vulnerable to xylem embolism than branches? New insights from X-ray computed tomography. Plant, Cell & Environment, doi: 10.1111/pce.12680.

Plants can be highly segmented organisms with an independently redundant design of organs. In the context of plant hydraulics, leaves may be less embolism resistant than stems, allowing hydraulic failure to be restricted to distal organs that can…

Acclimation to humidity modifies the link between leaf size and the density of veins and stomata

Murphy, MRC., Jordan, GJ, Brodribb, TJ, 2014. Acclimation to humidity modifies the link between leaf size and the density of veins and stomata. Plant Cell and Environment 37, 124-131

The coordination of veins and stomata during leaf acclimation to sun and shade can be facilitated by differential epidermal cell expansion so large leaves with low vein and stomatal densities grow in shade, effectively balancing liquid- and vapour-phase…

Leaf hydraulics and drought stress: response, recovery and survivorship in four woody temperate plant speciespce_2023

Blackman CJ, Brodribb TJ, Jordan GJ, (2009) 'Leaf hydraulics and drought stress: response, recovery and survivorship in four woody temperate plant species', Plant, Cell and Environment, vol.32, pp 1584-1595

Efficient conduction of water inside leaves is essential for leaf function, yet the hydraulic-mediated impact of drought on gas exchange remains poorly understood. Here we examine the decline and subsequent recovery of leaf water potential (Yleaf), leaf hydraulic…

Minimum hydraulic safety leads to maximum water-use efficiency in a forage grass

Holloway-Phillips MM, Brodribb TJ. 2011. Minimum hydraulic safety leads to maximum water-use efficiency in a forage grass. Plant Cell and Environment 34: 302-313.

Understanding how water-use regulation relates to biomass accumulation is imperative for improving crop production in water-limited environments. Here, we examine how the vulnerability of xylem to water stress-induced cavitation and the coordination between water transport capacity and assimilation…
