Fig. 4From: Genome-wide identification and characterization of superoxide dismutases in four oyster species reveals functional differentiation in response to biotic and abiotic stressStatistics of the TF families of Crassostrea gigas SODs. The x-axis showed the SODs of Crassostrea gigas, the y-axis showed the number of transcription factor families. The SODs were marked into six colors from clade “I” to “VI”Back to article page
