Our new work uncovering how WIND1 promotes somatic embryogenesis as a bifunctional chromatin regulator!!! We knew WIND1 promotes new fate acquisition and now we show WIND1 also helps repressing existing identity!
WIND1 controls cell fate transition through histone acetylation and deacetylation during somatic embryogenesis https://t.co/2K8lcfrBBG

Few things in science are as heart-warming as seeing one of your PhD or postdoc buddies start their own lab and begin absolutely KILLING IT with amazing discoveries!
I am excited to share the latest paper from my lab where we leverage the selection bias of condensate-promoting oncofusions to uncover molecular rules governing condensate specificity and function. https://t.co/AQlErs3lni.

Delighted to share this. A novel H4 variant that modulates chromatin to mediate salt stress response. This mammoth work was driven to perfection by @VivekHariSunda1, a wonderful PhD student who also taught me. We report its CryoEM structure & unusual chemistry @NCBS_Bangalore 1/3
New Article: "An Oryza-specific histone H4 variant predisposes H4 lysine 5 acetylation to modulate salt stress responses" https://t.co/e4usthp5xG An Oryza-specific histone H4 variant (H4.V) forms condensed, less stable nucleosomes, regulating the salt stress transcriptome.

> bacteria were engineered to make molecules that absorb light in unique ways. > the microbes were buried in soil. > using a drone with a hyperspectral camera, one can "see" where the microbes are buried from ~300 feet away. one of the most sci-fi papers I've seen in awhile.

Extremely clever new NGS tech from Roche 𧬠If it's hard to discriminate between nucleic acids accurately with a nanopore, why not synthesize a new polymer off a DNA template that is easier to sequence? It's an intuitively simple idea, but took *a ton* of creative nucleic acid

Transcription factors instruct DNA methylation patterns in plant reproductive tissues https://t.co/02iI5jAeEx

DNA methylation is maintained by forming self-reinforcing connections with other repressive chromatin modifications, resulting in stably silenced genes and transposons. However, these mechanisms fail...

Excited to share work from Zhongshou Wu in our lab showing that GDE1 and REM transcription factors help shape DNA methylation patterning. Together with work from Julie Lawβs lab also just out, this shows an important way that genetics directs epigenetics.

DNA methylation plays crucial roles in gene regulation and transposon silencing. In plants, the maintenance of DNA methylation is controlled by several self-reinforcing loops involving histone...

Here is something to distract you from the gloom: What can metagenomics tell us about the taxonomic composition of lichen symbioses? A peer-reviewed version of our analysis of >400 lichen metagenomes from around the world is now out in @PLOSBiology. 1/12 https://t.co/MMGDSEwm8H

We are grateful for the positive reception this has received :) Also realized we should fully credit a paper that inspired us & identified the TCX5/6 repressors. Our breakthrough wouldn't have been possible without this important work (Xin-Jian He's lab) https://t.co/dqpdvwCjGt
