Final Report Abstract

Plants are of essential importance for all life on earth as they convert sunlight, water, and carbon dioxide into chemical energy. Due to their sessile lifestyle plants exhibit a remarkable ability to appropriately sense and signal changes in environmental parameters in order to efficiently mount a suit of coordinated adaptive responses to these. Second messengers – and among these especially the simple ion calcium (Ca2+) – are central to the underlying signaling processes and for the coordination of downstream responses. The major aims of this research group were: (i) To advance and apply high-resolution biosensorics for monitoring the occurrence and dynamics of Ca2+ signals in plant model systems and model cell types. (ii) To identify and characterize the mechanisms and components that bring about the formation of Ca2+ signals. (iii) To investigate the function and regulation of Ca2+-dependent kinases that translate Ca2+ signals into phosphorylation-regulation of target proteins, with a focus on CDPKs and CBL-CIPKs. (iv) To identify and characterize the targets of these kinases and principles of their regulation. (v) To elucidate the interplay of Ca2+ signaling and hormonal regulation with a focus on ABA signaling as model case, and (vi) to enable modeling approaches building on quantitative datasets that reflect these signaling processes and allow further hypotheses generation. In our research, we used Arabidopsis thaliana as model organism and focused on roots as model organ as well as on guard cells, root hairs, and pollen tubes as model cell types for Ca2+ signaling processes. On the molecular scale, the regulation of various ion channels, NADPH oxidases, and transcription factors served as model cases for our studies. The accomplished scientific progress and the conceptual advances for the field of Ca2+ signaling, that were achieved through the implementation of FOR964, were summarized in a joint review publication of all PIs involved in this FOR (Kudla et al., 2018).
