Non-specific Phospholipase C4 Improves Phosphorus Remobilization From Old to Young Leaves in Camelina.

Camelina sativa is regarded as a low-input oilseed crop for versatile food, biofuels and industrial applications with potential production on marginal lands, whereas phosphate (P) deficiency greatly reduces camelina seed production. To improve camelina resilience to low P conditions, here we overexpressed the P deficiency-induced non-specific phospholipase C4 (NPC4) to test its effect on camelina seed production under different levels of P availability. NPC4-overexpressing (OE) plants displayed increased seed yield and oil production, with a greater magnitude of increases under P-deficient than P-sufficient conditions.
