Calcium Imaging Perspectives in Plants

The calcium ion (Ca(2+)) is a versatile intracellular messenger. It provides dynamic regulation of a vast array of gene transcriptions, protein kinases, transcription factors and other complex downstream signaling cascades. For the past six decades, intracellular Ca(2+) concentration has been significantly studied and still many studies are under way. Our understanding of Ca(2+) signaling and the corresponding physiological phenomenon is growing exponentially. Here we focus on the improvements made in the development of probes used for Ca(2+) imaging and expanding the application of Ca(2+) imaging in plant science research.
