Duplication of KCBP, which encodes a plant-specific microtubule-based kinesin motor, occurs solely in legumes of the clade that form symbiosomes. The nodule-enriched KCBP (nKCBP) is co-opted by rhizobia to control central vacuole morphogenesis in symbiotic cells, thus achieving symbiosome development and nitrogen fixation.
