Fig. 2From: Identification of differentially expressed genes in sunflower (Helianthus annuus) leaves and roots under drought stress by RNA sequencingVolcano plot of significantly differently expressed genes in leaves and roots under drought stress. Red and green dot represent the up-regulated and down-regulated genes, respectively. a Differential expressed genes in the leaves under PEG treatment (PEG _L) and control group (CK_L). b Differential expressed genes in the roots under PEG treatment (PEG _R) and control group (CK_R)Back to article page
