Osakabe, Y., et al. “ABA control of plant macro element membrane transport systems in response to water deficit and high salinity”. in (2013). New Phytologist (2014). 202: 35-39.
This article is a review on the signaling cascade induced by ABA in times of osmotic stress. It reviews the role of ABA in water deficit or high salinity in plants in relation to a plant’s ability to adapt to adverse conditions resulting from climate change (elevated temperatures and increased drought). Environmental stimuli activate ABA to initiate a complex signal transduction pathway. The pathway results in a stomatal response, a shift in metabolism, and the expression of many stress-response genes. ABA is an adaptation that controls the internal water status of plants during conditions that cause osmotic stress. Increased levels of ABA causes the stomata to close, thereby reducing the gas exchange rate and reduced photosynthetic activity. The review also goes into detail on which transporters and channels are involved in the signaling transduction pathway of ABA that helps modify the plants’ tolerance.
