Fig. 9From: Identification and characterization of the glucose dual-affinity transport system in Neurospora crassa: pleiotropic roles in nutrient transport, signaling, and carbon catabolite repressionIntracellular cAMP is significantly increased in Δ2hgt under cellulosic conditions compared with the WT. Samples of the WT and the Δ2hgt mutant cultured for 16, 24, 40, 54, and 98 h were harvested and assayed for cAMP levels. Values represent the means of two independent biological replicates within each of three technical replicates; error bars show standard deviations. Statistical significance was assessed using a two-tailed Student t test. *P < 0.05, **P < 0.01Back to article page
