How arbuscular mycorrhizal fungi maintain plant nitrogen acquisition under drought While arbuscular mycorrhizal fungi (AMF) influence plant nitrogen (N) acquisition and drought tolerance, the complex interactions governing N uptake under varying water deficits remain unclear. To addressing this, well-characterized mycorrhizal tomato type (MYC) and its mycorrhiza-defective mutant (referred to as rmc) were labeled with 15NH4Cl under normal and drought conditions in a greenhouse. We quantified 15N allocation in plant biomass and rhizosphere soil, while assessing shifts in activities of β-N-acetylglucosaminidase and leucine aminopeptidase. MYC increased tomato total biomass relative to rmc under both water regimes, with the most pronounced root biomass enhancement observed under drought (64–74%). Similarly, MYC increased tomato 15N uptake compared to rmc, with a greater increase under drought (80–104%) versus normal (55–94%) conditions. This phenomenon can be ascribed to elevated 15N enrichment in microbial biomass and increased activities of β-N-acetylglucosaminidase and leucine aminopeptidase. This was further supported by the positive correlations between tomato 15N acquisition and 15N incorporation into microbial biomass as well as activities of β-N-acetylglucosaminidase and leucine aminopeptidase. Collectively, AMF alleviated drought stress and improved plant productivity through enhanced root N-acquisition capacity, increased microbial biomass and enzyme secretion, and optimized soil N mineralization processes.

Climate niche models correctly predicted the direction of some empirically documented range shifts for bird species in the genus Tyrannus. CREDIT: Jeewantha Bandara.

Climate niche models underestimate the speed with which species move in response to climate change, according to comparisons between the models and observed shifts for more than 3,500 species. Median rates were four times faster than predicted. In PNAS: https://ow.ly/Mokn50YCqty

I am so proud of this paper ⬇️ recently published in PNAS 🤩 Four years in the making and countless computing hours to get bioclimatic velocities from species distribution models #SDMs that were tailored to each species and study from which we extracted empirical estimates of species range shift rates

Beautiful!

Working on our metatranscriptomics paper on montane soil fungal communities of NW Yunnan comes with an unexpected benefit: an excuse to browse photographs of oak and fir forests, Rhododendron woodlands, and alpine meadows that most mycologists will never visit in the field.

On the flank of a dead beech, the lumpy bracket has surrendered its corrugated surface to microscopic algae — a blazing chartreuse mantle in the March light. Two kingdoms in accidental alliance: death in the forest is never anything other than another way of proliferating.

Sur le flanc du fayard mort, la tramète bossue (Trametes gibbosa) s'est laissé coloniser par des algues microscopiques — un manteau de chartreuse vif qui flamboie. Deux royaumes en alliance de circonstance : la mort en forêt n'est jamais qu'une autre façon de proliférer.

We sequenced the genome of 'desert ginseng' (Cistanche deserticola) - a leafless parasitic plant that gave up photosynthesis - and found it lost huge chunks of its own genome…but started stealing genes from its host!

Transposable elements hitchhike on Starships across fungal genomes - Nature Communications Large mobile genetic elements known as Starships act as vehicles for transferring transposable elements (TEs) between fungi. Here, Griem-Krey et al. show that these ‘hitchhiking’ TEs can drive rapid e...

Now out!
We show that TEs can be horizontally transferred between fungal species via Starships. Once transferred, these TEs can become active, changing the genome organization and affecting the lifestyle of the recipient fungus.
