Extract
Plants perceive ever-changing environmental conditions and adjust their growth and development accordingly. Unlike animals, however, plants lack an equivalent system to the centralized nervous system for integrative processing of received external information. Instead, they rely on inter-organ communication via vascular tissues to acclimate to their environments through use of a variety of signal molecules (Notaguchi and Okamoto 2015, Tsutsui and Notaguchi 2017). This type of communication between organs is referred as to ‘systemic signaling’. Our knowledge on systemic signaling is mostly from studies in the model plant Arabidopsis thaliana but now has been expanded to other species including crops. In recent years, this field has been gained attention and many remarkable studies have been published on this topic, including several notable publications in Plant & Cell Physiology (PCP). Here, I aim to briefly summarize some of these key findings to help consolidate current knowledge on systemic signaling in plants.
