The growth and vigor of aerial parts of the plant was impaired; the nodules were still able to fix atmospheric Nitrogen but the aboveground tissues could not benefit for whatever reason. Nodules on repressed plants appeared later than in control plants and were smaller in size. traits: - entity_name: vascular bundle development trait entity: TO:0020109 - entity_name: plant organ growth and development trait entity: TO:0000927 - entity_name: shoot system entity: PO:0009006 - entity_name: vascular bundle entity: PO:0005020 - entity_name: root nodule entity: PO:0003023 references: - citation: Godiard, Lepage et al., 2011 doi: 10.1111/j.1469-8137.2011.03718.x pmid: 21679315 - citation: Oellrich, Walls et al., 2015 doi: 10.1186/s13007-015-0053-y pmid: 25774204
