WebNov 1, 2024 · However, if only sectoring colonies were counted 3.4% of the UV-irradiated cells (73/2118, N = 3) exhibited sectoring while 2.2% (23/1050, N = 3) of the non-irradiated cells exhibited sectoring. We suggest that the increase in GFP cells after UV exposure occurred after the third division in the clonal growth of the colony. 4.

Web‘‘survive’’ and reach the edge of the mature colony. From the view point of population genetics, the significance of this coars-ening process is that it leads to a gradual decrease in the genetic diversity at the wave front (9, 13) and generates a characteristic sectoring pattern in the neutral genetic makeup of a population. WebApr 7, 2024 · We performed a mutagenic screen to identify alleles that are lethal in 4Δ+ENTH cells using a colony‐sectoring reporter assay. After isolating candidate synthetic lethal genes by complementation, we confirmed that mutations in VPS4 led to inviability of a 4Δ+ENTH strain. Vps4 mediates the final step of endosomal sorting complex required for ...
WebMultiple features of a GFP sector, such as its size and position within the colony, as well as the overall pattern of colony sectoring, inform our understanding of heterochromatin dynamics. To quantitatively analyze these features, we developed an algorithm that detects the sectoring pattern (Fig. 1C).
