Analyses of mutants shows that the same VPYgene is also required for rhizobial colonization and nodulation. Plants mutated in this gene have abnormal rhizobial infection threads and fewer nodules, and in the case of interactions with AM fungi, epidermal penetration defects and aborted arbuscule formation. traits: - entity_name: root nodule number entity: TO:0000900 - entity_name: root system entity: PO:0025025 - entity_name: root nodule entity: PO:0003023 references: - citation: Pumplin, Mondo et al., 2009 doi: 10.1111/j.1365-313x.2009.04072.x pmid: 19912567 - citation: Oellrich, Walls et al., 2015 doi: 10.1186/s13007-015-0053-y pmid: 25774204
