Essential amino acids promote chronological longevity. The CLS of yeast competent (WT, atg11Δ) or deficient (atg1Δ, atg7Δ) in autophagy was measured in synthetic dextrose minimal medium containing histidine, lysine, leucine, and uracil supplements added to standard (SD) or three-fold elevated (3X HKLu) final concentrations as described in Table 2. Viability is expressed in terms of colony forming units (CFU) per ml of culture and is plotted as the log of the percent of viability on day 1.
