Grafting reveals organ-autonomous and feedback roles of root phloem development in source-sink dynamics.

Abstract excerpt

Carbon fixed in source leaves is partitioned between local use and long-distance transport through the phloem to heterotrophic sinks such as roots. Here, we investigated how mild defects in sink phloem differentiation influence whole-plant growth using two Arabidopsis mutants: ops, which exhibits short roots with protophloem differentiation defects, and ops opl2, which displays even shorter roots with combined...
