Other claims from this paper (7)

Other claims from this paper (6)

Intervention effect Kayanne pea maintained its yield after a 2-week water deficit.
Intervention effect In Puget pea, initiation of new nodules after water deficit was delayed relative to control plants.
Intervention effect In Puget pea, additional nodules developed after water deficit compared with control plants.
Intervention effect In Kayanne pea, nodule formation was rapidly and strictly re-adjusted to plant growth needs, allowing a full recovery after water deficit.
Association Plant growth recovery in pea was tightly linked to N nutrition.
Mechanism Rapid re-launch of N acquisition with fine-tuned nodule formation after water deficit is suggested to be essential for drought resilience in pea.
