additional information	-	PEPC activity and malate-inhibition ratio are less affected in wheat and rice under P-deficiency	Triticum aestivum
additional information	-	PEPC activity and malate-inhibition ratio are less affected in wheat and rice under P-deficiency	Oryza sativa
additional information	-	PEPC activity of the Brachiaria hybrid (C4 plant) leaves is 51- to 129fold higher than that estimated for wheat and rice (both C3 plants). PEPC activity in leaves and roots of the Brachiaria hybrid increases up to two-and three-fold, respectively, and decreases the malate-inhibition ratio in leaves in response to P-deficiency	Brachiaria hybrid cultivar
