Abstract excerpt

Cell-to-cell transport in plants occurs through cytoplasmic channels called "plasmodesmata" and is regulated by developmental and environmental factors. Callose deposition modulates plasmodesmal transport in vivo, but little is known about the mechanisms that regulate this process. Here we report a genetic approach to identify mutants affecting plasmodesmal transport. We isolated 5 mutants, named gfp arrested...
