Our latest paper is out in The Plant Cell! 🚀 @theplantcell.bsky.social
We identified BGH2, a suppressor of GLK transcription factors, as a key regulator of plastid homeostasis and light adaptation.
Huge thanks to everyone who supported and contributed to this work!

CRISPR targeting of H3K4me3 activates gene expression and unlocks centromere-proximal crossover recombination in Arabidopsis
Nature Communications - Binenbaum et al. demonstrate that precise CRISPR-based targeting of a key chromatin mark (H3K4me3) can switch on genes, boost disease resistance, and unlock meiotic...
