🌱🌿New Preprint!🪴🥬 Have you ever wondered how plants coordinate the supply of DNA precursors to organelles during germination? We show that VENOSA4 (VEN4) supports organellar genome replication by linking dNTP dephosphorylation with nucleotide salvage. doi.org/10.64898/202...

Excited to share our latest publication on genetic transformation in Nannochloropsis and Microchloropsis!🦠 We demonstrate a robust sulfadiazine-based selection system enabling efficient transformation with minimal background growth in these important algal model species. shorturl.at/BGdov

Sulfadiazine selection enables high‐efficiency transformation in <fi>Nannochloropsis</fi> and <fi>Microchloropsis</fi>

Genetic engineering in the marine eustigmatophytes Nannochloropsis and Microchloropsis is constrained by intrinsic antibiotic resistance and reduced marker efficacy at high salinity. We show that mit....

Excited to share our latest preprint on #PhycologyFriday. We map out the carbon fixation pathway for the first time in a multicellular alga, the green seaweed Ulva, and reveal a unique Rubisco-Linker interaction in the pyrenoid, a chloroplast condensate. Below I summarize some key points. #seaweeds

How microalgae use phytochrome to sense the ocean’s light #TansleyInsight by Duchêne et al. @afalciat.bsky.social nph.onlinelibrary.wiley.com/doi/10.1111/... #plantscience

Power of combining phytochromes action spectra with environmental light fields to discover new biological functions, as exemplified by the diatom phytochrome.

We genetically disconnected starch from the matrix in the algal pyrenoid! A saga1;saga2 double mutant lacks a starch sheath! Our model: SAGA1 & SAGA2 locally initiate starch on the pyrenoid surface by enriching starch precursors. 🌞🦠🔬🔌👀 www.biorxiv.org/content/10.6...

Marine #phytoplankton need move up/down in the #ocean to access light & nutrients. Study of the effects of nutrient availability in 9 species reveals that phytoplankton have evolved multiple mechanisms that impact gravitational sinking in response to starvation @plosbiology.org 🧪 plos.io/4iaJFoV

Gravitational sinking velocities are indicated in color-coded background. Top right: A transmission electron microscopy image of Tetraselmis sp., a green alga, reveals the internal organization and composition of the cell, as seen under high-growth conditions. Bottom right: A scanning electron microscopy image of Tetraselmis sp., portraying the sinking of the cell following starvation. Image credits: Teemu P. Miettinen, Margaret Bisher, Abigail K. R.
