Why Thrips Might Be the Unknown Heroes of Pollination

Thrips, tiny insects often seen as pests, play a key role in pollinating many plants, according to research in @annbot.bsky.social

Studies on the Japanese soil-borne wheat mosaic virus movement protein highlight its ability to bind plant RNA - Virology Journal

Background Plant viral movement protein (MP) function is decisive for virus cell-to-cell movement. Often, MPs also induce membrane alterations, which are believed to play a role for the establishment ...

If you would like to understand how difficult it is to annotate mobile mRNAs using SNPS read this.

Consider important suggestions/controls: homografts & heterografts, use barcoded reads, minimise RT-PCRs, have a reliable annotated/high quality genome sequence .. etc

Re-analysis of mobile mRNA datasets raises questions about the extent of long-distance mRNA communication - Nature Plants

This study reveals that a substantial number of transcripts that are currently annotated as graft-mobile lack statistical support from available RNA-seq data.

That is a huuuge deal! That might change the view on what a mobile RNA is. Congrats to the authors!

I completely abandoned IPTG. We use lactose in autoinduction medium. Much higher yield and more soluble protein as well.

Protein codes promote selective subcellular compartmentalization

Cells have evolved mechanisms to distribute ~10 billion protein molecules to subcellular compartments where diverse proteins involved in shared functions must assemble. Here, we demonstrate that prote...

Just out! Happy to share this awesome collaboration with the Pines and Kehr labs. As seen on BioRxiv, we developed a 15-minute protocol for on-site detection of crop RNA viruses using Cas13.
