A role for redox factors in shaping root architecture under Phosphorus deficiency

Jarosław Tyburski; Kamila Dunajska; Andrzej Tretyn Plant Signaling & Behavior 2010. doi:10.4161/psb.5.1.10199

Other claims from this paper (5)

Association The disappearance of ROS from the elongation zone coincides with arrest of root elongation under low P.
Intervention effect P-starvation decreased the ascorbic acid level in roots.
Intervention effect Feeding P-deficient plants with ascorbic acid stimulated mitotic activity in the primary root meristem.
Intervention effect Feeding P-deficient plants with ascorbic acid partly reversed the inhibition of root growth imposed by low P.
Observation Rapidly growing roots on P-sufficient medium synthesize ROS in the elongation zone and quiescent centre.
