A-C Wild‐type, atg2Δ, pho8Δ, and rny1Δ cells were grown in SD to mid‐log phase and transferred to SD(‐N) at time 0. At the indicated time points, 5′‐NMPs (B) were analyzed by LC/MS as described in . The results are presented as normalized intensities on the basis of the peak height of each metabolite in wild‐type cells. Note that 3′‐NMPs in pho8Δ are presented in a different scale. All data are means of triplicates. The error bars represent the standard deviation.
