Polygamy in trees? New paper shows that dual associations with ecto- and arbuscular mycorrhizal fungi improve the host range and environmental niche of trees. Ecology Letters: Rog et al.: dx.doi.org/10.1111/ele.70… When trees and soil fungi form close associations with each other, both partners benefit. Many tree species have further enhanced this cooperation by forming a concurrent symbiosis with two different groups of mycorrhizal fungi. Those trees cope better with water and nutrient scarcity, which is an important trait for forestry in the face of climate warming. Despite having enormous root systems, trees often are unable to take up enough water and nutrients from soil to grow in a healthy manner. That’s why most terrestrial plants have formed symbiotic associations with fungi over the course of evolution. These mycorrhizal fungi, which either wrap themselves around roots or penetrate the cells of root systems, receive part of the sugar produced by plant photosynthesis from trees as a source of energy. In exchange, trees receive nutrients like phosphate and nitrate as well as water from the fungi in an unromantic marriage of convenience of sorts. Using more than 400 different tree species spread around the world as a basis, researchers at the University of Zurich (UZH) and Agroscope have shown that many of them have further improved this cooperation system. Although most tree species form an association only with certain single members of different groups of mycorrhizal fungi, “some woody plants form an alliance with two fungus varieties simultaneously,” says Ido Rog from the Department of Plant and Microbial Biology at UZH. The researchers now show that “bigamy” of this kind improves tree fitness, making trees less sensitive to drought and rendering them better able to cope with nutrient scarcity. “They thus are able to colonize a much larger territory than tree species that form a symbiosis with only one fungus type can,” lead author Rog says. The broader geographical range and the expanded environmental niche space occupied by those trees are independent of their phylogenetic architecture and evolutionary history. In forestry, this knowledge could be helpful in the future for selecting tree species specialized in dual fungal associations because they are likely to be better at coping with ongoing global warming and could be used to colonize dry climate zones,” UZH professor Marcel van der Heijden explains.

Microbial inoculation works best in fields with poor soil health and low productivity. In our new paper led by Ido Rog, with Stefanie Lutz, Franz Bender, Raphaël Boussageon, Antonin Lambach, Klaus Schlaeppi & Natacha Bodenhausen we show that mycorrhizal fungal inoculation success depends on soil health and crop productivity. It is based on our analysis of field inoculation trials of 54 fields. Further studies and models need to confirm our observations. It nicely summarizes what has been indicated or observed by others.

@LukeLikesDirt @ido_rog @vandeHeijdenLab @ICOM_12 finally an excellent global biogeographic and phylogenetic study of dual mycorrhiza, a clear gap that we definitely needed to cover!!

Research by @ido_rog ⁦@vandeHeijdenLab⁩ shows that dual mycorrhizal trees are more ecologically flexible in climate space at the global scale. Looking forward to seeing this work in print! #ICOM12 @ICOM_12

Exciting Next Generation Scientist meeting! Thank you, @NewPhyt #npnextgen #roots #mycorrhiza

EIC + 5 future EICs of @NewPhyt #npnextgen

@karst_justine @PesWeizmann @abcdefs2s @LivneStav @YaaraoOppenhei2 @fox_hagar These are interesting questions! Happy to discuss it further at @ICOM_12

@ido_rog @PesWeizmann @abcdefs2s @LivneStav @YaaraoOppenhei2 @fox_hagar 2. Can't fungi produce amino acids? How do you know the amino acids were synthesized in the plant tissue? The C came from the tree but this doesn't mean amino acids did. I'm not clear why transfer from tree roots is necessary to explain these results. What am I missing?

Which carbon compounds are transferred from trees to ectomycorrhizal sporocarps? A new exciting publication from the @TheWeizmannTreeLab @PesWeizmann @abcdefs2s @LivneStav @YaaraoOppenhei2 @fox_hagar

@pamoehl @GlobalChangeBio Thanks!!!

@ido_rog @GlobalChangeBio congrats Ido!

@Daphnauni @Wkolby Congrats! Good luck!

Happy to share that I started my Postdoc at the University of Arizona a few weeks ago. Joining Earth Dynamic Observatory Lab led by @Wkolby. Super excited to be here, to combine tree ecophysiology with remote sensing tools in Arid ecosystems! A new chapter in our family journey

Thank you @Picarro for selecting me! @vandeHeijdenLab @TamirKleinLab

Successful microbiome engineering in agricultural fields. Our new paper in @NatureMicrobiol demonstrates that large-scale inoculation with arbuscular mycorrhizal fungi works and can promote crop yield up to 40%. nature.com/articles/s4156… @SteffiLutz; @NBodenhausen; @KSchlaeppi

@KatieField4 @SFranzBender1 @mrillig @SteffiLutz @fl_walder

Highlights for me included @SFranzBender1’s use of underpants to find out & teach people about soil health, hanging out & chatting all things soil ecology & global change with @mrillig, @SteffiLutz, @fl_walder, @ido_rog & Emily Durant’s presentation of her first data from PhD 🤩

Home after a super couple of days in Muttenz for the 1st European #HealthySoils2023 meeting - a really exciting and motivating conference, loved every minute - esp grateful for the chance to meet up with friends & collaborators, old & new! Thanks for inviting me ❤️🍄🌱
