In our new study led by @molivarina we found an unanticipated layer of cell identity in the plant root. A subset of cells in every cell type shares a common environment-responsive state, and their frequency shifts with conditions such as water availability nature.com/articles/s41586-0…

An environmentally regulated dichotomy in cell lineages of the root

Nature - An environment-regulated state is identified across multiple cell types at the root tip, revealing a shared dichotomy between cells with and without this state.

Are plant roots really made up of concentric layers of homogeneous, differentiating cell types? In our new study, out now in @Nature, we show a more complex picture: two distinct cell states within root lineages, shaped in part by the environment. 🧵👇 nature.com/articles/s41586-0…

When a #plant flowers, it doesn’t just make flowers - it changes the way it builds itself. New growth axes emerge and #branching patterns change! How is this transformation coordinated? Excited to share our new @PNASNews paper with @Zohar__Meir doi.org/10.1073/pnas.2605727…

In today’s seminar, Idan Efroni @efronilab presented his algorithm for uncovering conserved non-coding sequences that have quietly shaped plant gene expression over evolutionary time. These elements reveal the regulatory grammar we can reuse when designing promoters.🌱🍅🌻

300 Million year old plant DNA blueprint decoded🌿🧬 An international team led by Hebrew U's Prof. @efronilab in collaboration with researchers from @CSHL, @Cambridge_Uni and @UMass, identified 2.3M conserved sequences that still govern plant growth today. This discovery via the "Conservatory" tool opens new paths for more resilient crops. Read here: bioengineer.org/300-million-…

Hiding in plain sight! 2.3M conserved non-coding sequences traced back 300M years across 284 plant species Ground-breaking study in First Release @ScienceMagazine from labs of Madelaine Bartlett, Idane Efroni & Zach Lippman ▶️ doi.org/10.1126/science.adt8… ▶️ slcu.cam.ac.uk/news/hiding-p…
Phylogeny of the 284 species of plants included in Conservatory data set. Conservatory uncovered ~2.3 million conserved non-coding DNA sequences across 284 plant species from 72 families including eudicots, monocots, gymnosperms, and algae. Illustrations by Professor Madelaine Bartlett.

Wound repair demands extra energy and building blocks. In our manuscript, we show that wounding activates local sugar transport to funnel carbohydrates to the regeneration site. We also introduce a new glucose sensor in plants. Is this how plants coordinate repair and growth?

Wounding-Induced Redirection of Sugar Transport Fuels Tissue Repair

Wounding triggers growth programs to restore damaged tissues, creating a local surge in metabolic demand. How resource recruitment is modified to meet this demand is unclear. Here, we show that...

We found that cytokinin-induced LBDs drive radial growth in Arabidopsis root by reshaping primary cell wall pectin, in part through four pectate-lyase-like genes. Huge congrats to the fantastic postdocs who led this work: Lingling Ye and Xin Wang nature.com/articles/s41477-0…

Cambium LBDs promote radial growth by regulating PLL-mediated pectin metabolism

Nature Plants - This study reveals that LBD transcription factors in the cambium drive radial plant growth by regulating PECTATE LYASE-LIKE (PLL) enzymes that remodel cell wall pectin, promoting...

It was a busy summer at the Alonso-Stepanova Lab with four manuscripts now published. Pathy, Mario, and Anna's EBSn ethylene reporter paper is now available in the Plant Biotechnology Journal. onlinelibrary.wiley.com/doi/…

EBSn, a Robust Synthetic Reporter for Monitoring Ethylene Responses in Plants

Ethylene is a gaseous plant hormone that controls a wide array of physiologically relevant processes, including plant responses to biotic and abiotic stress, and induces ripening in climacteric...

Plant developmental genes share functions & expression, but align orthologs' promoters and often… no conservation. Or is there? In our new preprint, we show that conservation exists and is ancient, but was just obscured by genome complexity. biorxiv.org/content/10.1101/…

A deep-time landscape of plant cis-regulatory sequence evolution

Developmental gene function is conserved over deep time, but cis -regulatory sequence conservation is rarely found. Rapid sequence turnover, paleopolyploidy, structural variation, and limited...

New regulatory sequences? come from duplications. Regulatory sequences diverge asymmetrically amongst paralogs. One tends to keep the old sequence, while the other diverges, before being fixed. Not all lineages are the same. Some (Poaceae!) underwent massive divergence early on.

You can explore the dataset for 283 plant species at conservatorycns.com. We welcome questions and suggestions! Finally, none would have been possible without Kirk Amundson, Anat Hendelman, and the collaboration we maintained through very dark and difficult times.
