Fig. 5From: 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 stressesRelative expression levels of ItfWRKYs across various tissues. A heat map with clustering is created based on the FPKM value of ItfWRKYs. The coloured scale varies from green to red, indicating relatively low or high expressionBack to article page
