Other claims from this paper (8)
- Observation Root hair invasion and early cortical infection resembled herbaceous legume nodules, with fewer cells infected.
- Observation Infection threads remained active behind the nodule meristem throughout growth and spread infection to new cells.
- Observation Leghemoglobin distribution in mature nodules matched active bacteroidal tissue in apical zones.
- Mechanism Endodermal thickening and suberization apparently restricted diffusion and aeration.
- Mechanism Cell-wall thickening delayed or prevented necrosis in proximal nodule areas.
- Mechanism A protective periderm replacing outer cortex enhanced nodule longevity.
- Observation Nodule rootlets were observed on six- to eight-month-old nodules.
- Observation Nodule rootlets developed from lateral vascular strand branches and terminal extensions of apical vascular bundle tips.
