Subcellular Localizations and Temperature Stress Responses of Auxin Transporters in Outer Root Tissues of A. thaliana

To secure food production in the increasingly extreme temperatures of present day, the development of heat- and cold-resistant crops is of absolute necessity. An integral step in this process is charting the molecular mechanisms underlying the innate temperature stress responses of plants, a task commonly approached using Arabidopsis thaliana. Many temperature stress responses depend on the precise distribution of auxin and the network of transporters responsible for the establishment and maintenance of this distribution, and in this review, the subcellular localizations and temperature stress responses of the outer root tissue-portion of these transporters have been charted. Given the fragmented nature of our current knowledge in this domain, this review seeks to provide a comprehensive overview of existing findings while also identifying both broad and targeted areas for future research.
