How does molecular valency shape condensate assembly and function? We used the CO2-fixing organelle in algae—the pyrenoid—to find out… 🧵

It is an illustration of some of our plant transgenic lines imaged during the optimization of our protocol.

Optimizing our plant imaging protocol and having fun along the way 😜

We have done our first @protocolsio.bsky.social. Are you interested about #genome_annotation quality evaluation? We have developed a tool called #GAQET2 (github.com/victorgcb198...) which runs several tools like #AGAT, #BUSCO, and many other tools. You can find it at www.protocols.io/view/structu...

Bethel at the 2025 colloquium of the Association Femmes et Sciences

Bethel Dereje attended with curiosity the 2025 colloquium of the Association Femmes et sciences. This organization that advocates for gender equality in science from preschool all the way to higher education. What an inspiring picture of a talented young scientist full of enthusiasm 🥰

Fluorophore-based Genetically Encoded Biosensors for Ratiometric Fluorescence Imaging in Microbes Investigating small-molecule dynamics within microbes is essential for comprehensive studies of microbial function. Both intra-organism and inter-organism small molecule dynamics play critical roles in microbial physiology, symbiosis, and disease. However, monitoring these dynamics remains highly challenging using most existing techniques. Fluorophore-based genetically encoded biosensors are powerful tools for tracking small-molecule dynamics in vivo and hold high potential for driving new discoveries. These biosensors are most commonly used in fluorescence imaging, often in combination with perfusion devices that allow precise control over environmental conditions. When integrated with advanced imaging techniques, this approach provides high-resolution, spatially and temporally resolved data, enabling insights into single-cell microbial responses. Despite their promise, implementing such biosensors remains technically challenging. Understanding the key steps is crucial for broader adoption. Here, we present a protocol designed to support the effective deployment of newly engineered biosensors into microbes for quantitative ratiometric fluorescence imaging under controlled conditions.

Our new protocol paper is out in JoVE.
