Sensors for quantification, localization and analysis of dynamics of plant hormones.

Plant hormones play important roles in plant growth and development, physiology and in acclimation to environmental changes. The hormone signaling networks are highly complex and interconnected. It is thus important to not only know where the hormones are produced, how they are transported and how and where they are perceived, but also to quantitatively monitor their distribution quantitatively, ideally in a non-invasive manner. Here we summarize the diverse set of tools available for quantifying and visualizing hormone distribution and dynamics. We provide an overview over the tools that are currently available - including transcriptional reporters, and degradation sensors, luciferase and fluorescent sensors - and compare the tools and their suitability for different purposes.
