grapevine species from varied native habitats exhibit differences in embolism formation repair associated with leaf gas exchange and root pressure
Plant Cell and Environment, 2015Co-Authors: Thorsten Knipfer, Ashley Eustis, Craig R Brodersen, Andrew Michael Walker, Andrew J McelroneAbstract:Drought induces xylem embolism formation, but grapevines can refill non-functional vessels to restore transport capacity. It is unknown whether vulnerability to embolism formation and ability to repair differ among grapevine species. We analysed in vivo embolism formation and repair using x-ray computed microtomography in three wild grapevine species from varied native habitats (Vitis Riparia, V. arizonica, V. champinii) and related responses to measurements of leaf gas exchange and root pressure. Vulnerability to embolism formation was greatest in V. Riparia, intermediate in V. arizonica and lowest in V. champinii. After re-watering, embolism repair was rapid and pronounced in V. Riparia and V. arizonica, but limited or negligible in V. champinii even after numerous days. Similarly, root pressure measured after re-watering was positively correlated with drought stress severity for V. Riparia and V. arizonica (species exhibiting embolism repair) but not for V. champinii. Drought-induced reductions in transpiration were greatest for V. Riparia and least in V. champinii. Recovery of transpiration after re-watering was delayed for all species, but was greatest for V. champinii and most rapid in V. arizonica. These species exhibit varied responses to drought stress that involve maintenance/recovery of xylem transport capacity coordinated with root pressure and gas exchange responses.

smilax Riparia reduces hyperuricemia in mice as a potential treatment of gout
The American Journal of Chinese Medicine, 2014Co-Authors: Chunfeng Zhang, Samantha Anderson, Yanwen ZhangAbstract:The roots and rhizomes of Smilax Riparia, called "Niu-Wei-Cai" in traditional Chinese medicine (TCM), are believed to be effective in treating gout symptoms. However, it is not clear if the uricosuric mechanisms of S. Riparia support its therapeutic activities. In this study, we examined the efficacy of S. Riparia in reducing serum uric acid levels in a potassium oxonate-induced hyperuricemia mouse model. We observed that the total saponins of S. Riparia could down-regulate renal mURAT1, resulting in the enhancement of urate excretion in the kidney of hyperuricemic mice. These results suggest that S. Riparia could be an active anti-gout herbal medicine, which would contribute to the enhancement of uric acid excretion in the kidney.

Drowned, buried and carried away: effects of plant traits on the distribution of native and alien species in Riparian ecosystems
The New phytologist, 2014Co-Authors: Jane A. Catford, Roland JanssonAbstract:Riparian vegetation is exposed to stress from inundation and hydraulic disturbance, and is often rich in native and alien plant species. We describe 35 traits that enable plants to cope with ripari ...
