A single person could conduct such a screen in a period of months, making it a much less daunting project than the execution of an EMS or P element screen.
In the present study, we used a genome-wide P-SUP transposable element screen for hypoxia tolerance during all developmental stages in flies, starting from embryos at 5% O2.
In this way we assessed candidate genes from the GS element screen, i.e. the heavy and light chains of Drosophila ferritin (Fer1HC and Fer2LC) and carbonyl reductase by over-expression of the Drosophila enzyme Sniffer (SNI).

A third component of the planar cell polarity pathway, grainy head (grh), was identified from the P-element screen.
From the P-element screen we obtained 33 modifiers of the Dys phenotypes (Table 1), 25 of which also showed interaction with Dg (Figure 4).
The modifier screens using EMS produced similar phenotypes to those observed in the P-element screen (Figure 4) and additionally produced a "posterior crossveinless" class (14/27 modifiers; Figure S2).
A list of all the genes included in our P-element screen is attached as supporting information, Table S2.
In summary, the P-element screen is a distinct method for identifying genes that lead to hypoxia tolerance in Drosophila.
Using Notch signaling inhibition and a P-element screen, we have experimentally validated that the up-regulation of Notch signaling is critical to the survival of hypoxia tolerant Drosophila strains [ 23, 26].

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
