B-D Time‐dependent changes in nucleoside contents under nitrogen starvation (B), rapamycin treatment (C), and carbon starvation (D) conditions. Wild‐type and atg2Δ cells were grown in SD and transferred to SD(‐N), SD medium with 0.2 μM rapamycin, or SD(‐C) at time 0. At the indicated time points, nucleosides were analyzed by LC/MS as described in . Results are presented as normalized intensities on the basis of peak height of each metabolite in wild‐type cells. All data are means of triplicate samples. The error bars represent the standard deviation.
