| Research Abstract |
Fluorescent probes that track and monitor dynamic status of biopolymers, such as cellulose microfibrils, in living plant cells are essential for next-generation dynamic studies of plant cell wall. In this study, we fused in tandem a signal peptide from cell wall protein (expansin), a crystal cellulose-binding module from cellulose degrading enzyme (cellobiohydrolase from Trichoderma reesei), a membrane-spanning domain of plasma membrane receptor (BRI1), and green fluorescent protein (GFP), and transiently expressed this fusion protein in onion epidermal cells. GFP fluorescence was detected in cortical regions as dotts but not in linear filaments. Detailed observation using transgenic plants is necessary.
