Amphistomatic leaf surfaces independently regulate gas exchange in response to variations in evaporative demand

Freya Richardson, Timothy J. Brodribb, Gregory J. Jordan; Amphistomatic leaf surfaces independently regulate gas exchange in response to variations in evaporative demand, Tree Physiology, Volume 37, Issue 7, 1 July 2017, Pages 869–878, https://doi.org/10.1093/treephys/tpx073

The occurrence of amphistomatic leaves (stomata on both surfaces) versus hypostomatic leaves (stomata limited to the lower or abaxial surface) has strong associations with environment. Amphistomy provides the advantage of higher conductance of CO2 for photosynthesis, however, unless…

Significant contribution from foliage-derived ABA in regulating gas exchange in Pinus radiata

The complex regulatory system controlling stomata involves physical and chemical signals that affect guard cell turgor to bring about changes in stomatal conductance (gs). Abscisic acid (ABA) closes stomata, yet the mechanisms controlling foliar ABA status in tree…

Drought avoidance and vulnerability in the Australian Araucariaceae

Zimmer HC, Brodribb TJ, Delzon S, Baker PJ. Drought avoidance and vulnerability in the Australian Araucariaceae. Tree Physiol. 2016 Feb;36(2):218-28. doi: 10.1093/treephys/tpv111.

The Araucariaceae is an iconic tree family. Once globally important, the Araucariaceae declined dramatically over the Cenozoic period. Increasing aridity is thought to be responsible for extinction and range contraction of Araucariaceae in Australia, yet little is known…

Responses to mild water deficit and rewatering differ among secondary metabolites but are similar among provenances within Eucalyptus species

Adam B. McKiernan, Brad M. Potts, Timothy J. Brodribb, Mark J. Hovenden, Noel W. Davies, Scott A.M. McAdam, John J. Ross, Thomas Rodemann, and Julianne M. O'Reilly-Wapstra Responses to mild water deficit and rewatering differ among secondary metabolites but are similar among provenances within Eucalyptus species Tree Physiol first published online October 23, 2015 doi:10.1093/treephys/tpv106

Water deficit associated with drought can severely affect plants and influence ecological interactions involving plant secondary metabolites. We tested the effect of mild water deficit and rewatering on physiological, morphological and chemical traits of juvenile Eucalyptus globulus Labill. and Eucalyptus viminalis Labill….

Evolution in the smallest valves (stomata) guides even the biggest trees

McAdam SAM, Brodribb TJ. Evolution in the Smallest Valves (Stomata) guides even the biggest trees. Tree Physiology 35: 451-452

The regal stature of the redwood sister-giants, Sequoia and Sequoiadendron, makes them internationally renowned icons of size and longevity. Yet an examination of the evolutionary history of the sequoiid clade (which includes the dawn redwood— Metasequoia) quickly dispels…

Stomatal (mis)behaviour

Brodribb TJ, McAdam SAM. 2011. Stomatal (mis)behaviour. Tree Physiology 31(10): 1039-1040.

When stomata first evolved they initiated the greening of terrestrial earth, and now more than 400 million years later these simple bi-cellular valves in the leaf surface regulate global fluxes of water and carbon. Despite their importance and…
