Duckweeds are an important plant research model but have been challenging to modify genetically. A study published in @newphyt.bsky.social by the Marí-Ordóñez group at the GMI, presents a new and highly reproducible method for genetic transformation in the duckweed species Spirodela polyrhiza.

How tree rings help scientists understand disruptive extreme solar storms A study published this week shows that how trees store and use radiocarbon left over from ancient solar storms can tell scientists a lot about these ancient storms and help them refine estimates of…

Scientists have long relied on tree rings to learn about solar storms.

A Tansley review published this week shows that trees don’t all record this carbon in the same way. Understanding those differences is key to interpreting Earth’s history of space weather.

New paper alert🔔My last PhD chapter is published📣
Our new study explains how the ratio of sapwood to leaf area🌿varies with hydraulic traits and climate on a global scale. Our theoretical model can capture almost 60% of trait variation.
Stay tuned! Blog is on the way

(🧵 6/6) Together, the team conducted extensive fieldwork across East and Southeast Asia to understand how pollinator shifts shaped the origin and range dynamics of plant species.

(🧵 5/6) This study emerged from a collaborative effort with Yao-Wu Xing (Xishuangbanna Tropical Botanical Garden, China) and Hong Truong Luu (Institute of Advanced Technology, Vietnam), integrating field pollinator observations with phylogeography and comparative morphology.

(🧵 4/6) Working with his advisor, Richard Ree at the Field Museum, USA, he investigates how pollinators have shaped plant evolution in the Asian bird-pollinated genus Aeschynanthus.
