Fig. 7From: Genome-wide identification, characterisation and functional evaluation of WRKY genes in the sweet potato wild ancestor Ipomoea trifida (H.B.K.) G. Don. under abiotic stressesResponses of ItfWRKYs to adverse environmental stresses. Expression profiles under four abiotic stresses (cold, heat, drought and salt) were analysed. The coloured scale varies from green to red, which indicates the low or high expression of each geneBack to article page
