Description of YMR090W: Putative protein of unknown function with similarity to DTDP-glucose 4,6-dehydratases; GFP-fusion protein localizes to the cytoplasm; up-regulated in response to the fungicide mancozeb; not essential for viability[1][2][3]

UW-Stout/Sensitivity To Nitrogen Starvation

Growth of YMRO90W on synthetic defined media (SDC).
Growth of YMRO90W on omission media that lacks nitrogen.

Knocking out the YMRO90W seems to have no effect on growth after incubating for 5 days on the Nitrogen omitted media.

Ultraviolet Sensitivity

YPL068C is more sensitive than YMR090W given that there is less colonizes present when under the same stress.

DNA and RNA Details

Other DNA and RNA Details

Other Topic: expression

Specifically higher expression in nitrogen limited chemostat cultures versus nitrogen excess. [4] [5]

This gene is part of the UW-Stout Orphan Gene Project. Learn more here.

Growth Curve

ymr090w growth.png

In a BY4735 background, knocking out YMR090W seems to have a moderate effect on growth rate in log-phase. In this assay, the BY4735 strain's doubling time was 124 minutes, while the YMR090W knock-out strain's doubling time was 208 minutes.

G-418 Stress


In the BY4735 background, knocking out YMR090W seems to have a little effect on the growth rate. In the knock-out experiment, the BY4735 strain's doubling time was 149 minutes, whereas the YMR090W knock-out strain's doubling time was 242 minutes. The calibration experiment, the BY4735 strain's doubling time was 64 minutes, whereas the YMR090W knock-out strain's doubling time was 95 minutes.

Methanol Sensitivity

The wild type had a doubling time of 170 min, the YMR090w had a doubling time of 225 min. The doubling time increased for both after we added the methanol which means that this strain is sensitive.

Stressing with Hydroxyurea

Hydroxyurea Protocol -The wild type strain had only a small difference in doubling time when stressed with Hydroxyurea;YMR090W showed about a 30 minute difference in doubling time compared to the wild type strain, indicating that this gene most likely plays a role in DNA replication.

Fermentation protocol link [2] - There appears to be no major difference in fermentation rate. The lower final ethanol percentage could be a result of evaporation. If this experiment were to be carried out again then it should be done in an air tight container.
