A confocal microscopy image shows root-colonizing bacteria clustering around an emerging lateral root, where localized glutamine leakage induces spatially confined reporter activity.

Using precise spatial and temporal analysis, researchers in Science provide insight into how bacteria around the root interact both with the plant and with each other.

@shanice-webster.bsky.social looks at iron status in plant-microbiome interactions. Proteobacteria and firmicutes are typically balanced in the microbiota, but iron starvation can really mess with that, going to dysbiosis. Used “mfec” Arabidopsis quadruple mutant.

Excited to share that the Zhu Lab will officially open at Texas A&M University on August 1st, 2025!

We’re a multidisciplinary group, exploring how plant roots adapt their growth to environmental stresses across scales. Actively recruiting!

Infrared imaging shows heat levels in sun-exposed leaves of Alstonia scholaris from the Australian Wet Tropics.

As the world warms, plants in natural ecosystems and agricultural settings find ways to respond to the heat.

In a new special issue of Science, researchers examine how heat affects plants at multiple scales, from the molecular level to the biosphere. (THREAD 🧵) scim.ag/44cSw3Z

Thanks George!

My former PhD student, a current postdoc at Duke, was one of the speakers at the MIT Catalyst Symposium yesterday. I heard it was a great talk!

Plant health is essential to food security, yet pathogens continue to threaten crops worldwide. To better understand how disease takes hold—& how to stop them—HHMI Hanna Gray Fellow @shanice-webster.bsky.social is exploring the dynamic relationships among plants, microbes, & disease-causing agents.

#CIDDSeminar This Thursday, April 24, 2025, Shanice Webster, Postdoctoral Associate and Hanna Gray Fellow at Duke University will present on metabolites and nutrients as key modulators of microbiota selection and plant health.

ExPOSE: a comprehensive toolkit to perform expansion microscopy in plant protoplast systems This method provides a robust approach for performing expansion microscopy in plant protoplasts for imaging single-cell and subcellular compartments at greatly enhanced resolution.

Some of my postdoc work has been "exposed" today in @theplantjournal.bsky.social! 😁🎉🔬 We developed ExPOSE - a method to perform expansion microscopy in plant protoplast systems. Here's a quick🧵of the details: @meter76.bsky.social @lily-oconnor.bsky.social
