Getting to the Bottom of Fungal Functions Across Earth’s Forests

April 23, 2024

Researchers have pioneered new understanding of which fungi take on certain functions at the forest floor. For the first time, they compared three different fungal guilds in a range of different locations. They sampled soils in four forest ecosystems, extracted RNA to understand gene expression, and developed new tools to map that soil RNA to fungal genomes.

It’s a tough job, but someone’s got to do it. In this case, the “job” is the breakdown of lignin, the structural molecule that gives plants strength and rigidity. One of the most abundant terrestrial polymers (large molecules made of repeating subunits called monomers) on Earth, lignin surrounds valuable plant fibers and other molecules that could be converted into biofuels and other commodity chemicals – if we could only get past that rigid plant cell wall.

JGI Researchers Trace the Evolution of Shiitake Mushrooms

February 28, 2023

These fungi are part of the genus Lentinula, which have evolved to decompose hardwoods on every continent besides Europe and Antarctica. Lentinula mushrooms are white rot fungi, belonging to an elite group of decomposers that can break down all of wood’s components — cellulose, hemicellulose, and the toughest molecule, lignin. Understanding Lentinula genomes and their evolution could provide strategies for converting plant waste into sugars for biofuel production.
