Extroardinary work on this Tansley review about mycelial dynamics in AM fungi, by @vkokkoris.bsky.social in @newphyt.bsky.social's latest.

#Arbuscular #mycorrhizal #fungi #symbiosis

I had such fun thinking, reading and writing this Tansley Review on #arbuscular #mycorrhizal #fungal mycelia. We need a more fungal-centric view to better understand not only the AM fungi, but also their many ecological roles.

Yet another example of the importance of natural history collections. Here, helping to address two questions:

• Responses to climate change (here, temperature and precipitation mattered in different ways)

• What sets range limits

(🧵 3/6) This review looks at how plant traits like leaf width, photosynthesis, and stomatal function affect water use efficiency, and how breeding and technology can improve crop resilience and yield.

(🧵 2/6) C₄ plants use water efficiently, helping them grow well in hot, dry climates. But climate change, including rising CO₂, heat, and drought still threatens their productivity.
