INCREASED LEVEL OF POLYPLOIDY1, a Conserved Repressor of CYCLINA2 Transcription, Controls Endoreduplication in Arabidopsis Abstract. Endoreduplication is a type of cell cycle in which DNA replication continues without cell division. We have isolated several dominant mutants fro

ILP1 T-DNA mutants have a slight reduction in endoreduplication: academic.oup.com/plcell/artic...

E.coli mutants deficient in ribose phosphate isomerase can only grow on glycerol when they express a functional rubisco. This provides a tool for screening Rubisco sequence variants. Doing so reveals rare mutations that improve CO2 affinity. There is still room for Rubisco engineering! #PlantScience

Scientists have developed PlantRNA-FM, an AI model that deciphers the genetic "language" of #plants, analyzing RNA sequences & structures.

Trained with 1,124 species, predicts RNA functions & structural patterns, aids understanding of RNA's role in #nature.

Emergent patterns of reef fish diversity correlate with coral assemblage shifts along the Great Barrier Reef - Nature Communications Coral reefs have been severely affected by anthropogenic stress. Using long term data from the Great Barrier Reef, this study found temporal changes in the latitudinal diversity gradient, and stronger...

Great Barrier Reef fish reveal that large-scale macroecological patterns have changed significantly 🐟🐠

We found that changes in latitudinal diversity gradient & rising species turnover were strongly correlated with shifts in coral composition

Wow! Where is this?

So cool !

Here is our latest preprint. Fusions of Cas9 to specific viral 5' exonucleases increase homology directed repair 30-fold in transient and 10-fold in stable transformations. Making non-selectable knock-ins and gene replacements possible. Congrats to the whole team! www.biorxiv.org/content/10.1...

C4 photosynthesis is beautifully intricate/complex but has evolved repeatedly. How did evolution change gene expression to enable this? Basically, C4 genes acquire elements in cis that plug them to existing cell identity networks.

Italy tests first gene-edited vines for winemaking - Nature Biotechnology Europe’s first field trial of gene-edited vines began in northern Italy on 30 September 2024. Developed by EdiVite, a spinoff from the University of Verona, these Chardonnay vines have undergone gene ...

Europe’s first field trial of gene-edited grape vines have begun in northern Italy. Developed by EdiVite, Chardonnay vines have undergone gene inactivation to enable them to better defend themselves against downy mildew, a major fungal disease

Here we show by single-nucleus RNA sequencing of Moricandia arvensis reveals bundle sheath cell-specific expression of photorespiration genes and associated pathways beyond glycine decarboxylase, including ammonium
assimilation and redox regulation.
