The 3D genome of Gigaspora margarita unveils stable chromatin and nucleolar organization and symbiont‐dependent genome dynamics

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2799-2817, September 2026.
Summary Arbuscular mycorrhizal fungi (AMF) are widespread plant symbionts that enhance nutrient acquisition and influence ecosystem productivity. Previous chromosome‐level assemblies of the model species Rhizophagus irregularis revealed a two‐compartment genome architecture (active A and repressed B chromatin compartments), yet its conservation across ...

Changes in photosynthesis and grazing facilitate growth of a mixotrophic protist under ocean acidification and warming

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2574-2587, September 2026.
Grazing rates of Ochromonas CCMP2951 expressed as carbon obtained per mean cell volume (a) and Caut/het‐photosynthetically fixed carbon divided by carbon obtained through grazing (b) in the four experimental treatments. Summary Mixotrophic protists capable of both photosynthesis and phagotrophy are key members of marine plankton communities.
