Growth Curve
In a BY4735 background, knocking out YLR426W seems to have a substantial effect on the strain's growth in complete media. In this assay, the BY4735 strain's doubling time was 162 minutes, while the YLR426W knock-out strain's doubling time was 660 minutes. (These doubling times are the means of three experiments.)
Hydroxychloroquine
HCQ refers to hydroxychloroquine
Under normal conditions, the BY4753 doubling time is 144 minutes, while that of YLR426W is 139 minutes. This proves that both of these strains grow at a similar rate. When grown in an environment with hydroxychloroquine, YLR426W doubled in 505 minutes, while BY4753 doubled in 276 minutes. Both strains are inhibited by hydroxychloroquine, but YLR426W growth is staggered much more. This is a possible indicator that the knocked-out gene was involved in cellular protection from hydroxychloroquine. (These doubling times and curves are the means of three experiments.)
Salt Concentration (NaCl)
0mM NaCl conc. BY4735 strain's doubling time: 169 minutes
0mM NaCl conc. YLR426W strain's doubling time: 481 minutes
750mM NaCl conc. BY4735 strain's doubling time: 294 minutes
750mM NaCl conc. YLR426W strain's doubling time: 909 minutes
The graph above shows the growth rate for the previously listed strains and the relative level of NaCl concentration. Knocking out the gene negatively and severely impacted the growth rate. Comparing the YLR426W doubling times between 0mM and 750mM NaCl, there is a tremendous effect on the growth rate. This effect negatively influences the knockout strain's (YLR426W) growth rate.
