I am happy to share our latest paper on human PIF1, a wonderful collaboration with Raphael Guerois, Ralf Seidel and Ulrich Rass and their teams. Human PIF1 is quite different from its yeast counterpart. Congratulations to Akshay Jayachandran, the first author.

Beautiful paper by Akshay Jayachandran @cejkalab.bsky.social and co-workers delineating the functional divergence of yeast and human PIF1. It was a pleasure making a small contribution to the study @gdsc-sussex.bsky.social @sussex.ac.uk! www.genesdev.org/cgi/doi/10.1....
Schematic showing that human PIF1 clears secondary DNA structures by coupled DNA unwinding and rewinding activities while not driving D-loop progression like yeast Pif1.

🌱 RESEARCH 🌱

HFR1 regulates chlorophyll biosynthesis and protochlorophyllide accumulation partly through PIFs during the de-etiolation process, thereby influencing singlet oxygen production and resultant photo-oxidative bleaching - Chaturvedi et al.

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪
Fig. 1.HFR1 suppresses greening in etiolated seedlings. (A) Col-0 (WT), hfr1-5, HFR1(ΔN)-OE, pif1-1, hfr1pif1, and pifq were germinated on half-strength MS medium at 22 °C in the dark for 4 d and further exposed to 2 d continuous light at 100 μmol m−2 s−1. Top row: cotyledons of representative seedling. Bottom row: cluster of seedlings, showing the degree of greening of etiolated seedlings after light exposure. Scale bar=1 mm. (B) Greening percentage and (C) total chlorophyll content of light-exposed seedlings in (A). (D) Relative fluorescence emission of etiolated seedlings in (A). Peak height at 636 nm indicates the amount of Pchlide. One-way ANOVA, followed by Dunnett's post hoc test was used to determine statistically significant differences. *P-value < 0.05. n = 3.

Check out a novel method for studying Phase 2 meiotic recombination in #buddingyeast that uncovers interactions between RAD54, TID1, and PIF1.

Read more in #GENETICS about how this assay can be applied to other recombination genes to understand double-stranded break repair.

Started Pokemon: Infinite Fusion Hoenn and my god it’s so good to be back. They have added so many more sprites since PIF1 and even though the game is in beta and you can only do up to the third gym, there’s so many possibilities already. This is my team so far!
Breloom/machoke fusion named Shroomfry, which i always name my Breloom because it's my favourite pokemon ever. The fusion sprite is a Humanoid muscular Breloom with a lanturn staff conjuring a mushroom circle. Sprite by .nottomention A Umbreon/Gardevoir fusion named Recluse, after the Nightreign character. The fusion sprite is a crescent moon black mage gardevoir with umbreon colours. Sprite by Sprite by monoski1 & mamobot Delphox/Golisopod fusion named Master Sura, after the chaos mage from Wizard of Legend. The Sprite is a wise-looking fisherman catching a flaming koi fish. Sprite by .nottomention A mightyena/manetric fusion named Black Doom, after the antagonist from Shadow the Hedgehog. Looks like Mega manetric except the body is more mightyena and the lightning bolt on it's back is red thunder instead of part of the body. Sprite by rdelpreti
