Hidden inside every growing hypha lies a microscopic powerhouse — the #Spitzenkörper.
It’s not just a blob at the fungal tip — it’s the traffic controller, architect, and GPS of fungal growth. 🍄
This video will uncover how this mysterious vesicle cluster orchestrates the very architecture of life beneath our feet.

Researchers discover #evolutionary 'tipping point' in #fungi.
Scientists have found a "tipping point" in the evolution of fungi that throttles their growth and sculpts their shapes. The findings, published in the journal Cell Reports, demonstrate how small changes in environmental factors can lead to huge changes in evolutionary outcomes.

A fitness landscape instability governs the morphological diversity of tip-growing cells https://www.sciencedirect.com/science/article/pii/S2211124724002894
"they found that the fitness landscape for hyphae contained an overhanging cliff and that this acts as a barrier to #evolution, strongly limiting the shapes... #hyphae with shapes near the brink of the tipping point would be particularly vulnerable to small environmental, chemical, genetic changes"

Lactophenol cotton blue stained #Mucor sp. There are blue stained #hyphae without clear septa poking out from a tangled core. The core is full of mature and immature #sporangia looking like smooth round structures and collections of small spores respectively. The tangle has a little more purple to it. One prominent hypha ends in a smooth immature sporangia.

Transcription activator-like effector protects bacterial #endosymbionts from entrapment within fungal hyphae: Ingrid Richter et al. https://www.cell.com/current-biology/fulltext/S0960-9822(23)00623-1
"the #bacterial species #Mycetohabitans rhizoxinica lives happily in the #hyphae of the #fungus #Rhizopus microsporus only when the #bacteria produce a certain protein."
A new study on the coexistence of bacteria and fungi shows that a mutually beneficial, functioning symbiosis can be very fragile. Researchers at the Leibniz Institute for Natural Product Research and Infection Biology (Leibniz-HKI) in Jena found out that the bacterial species Mycetohabitans rhizoxinica lives happily in the hyphae of the fungus Rhizopus microsporus only when the bacteria produce a certain protein. The research is published in the journal Current Biology.
The Toxin That Helps Oyster #Mushrooms Devour Worms https://www.nytimes.com/2023/01/18/science/oyster-mushrooms-carnivorous-toxins.html
Carnivorous #mushroom paralyzes, kills #nematodes via a volatile ketone https://www.science.org/doi/10.1126/sciadv.ade4809
It’s not just the #OysterMushroom. Some #fungi craft sticky nets laced with tempting scents to snare their prey. Others create collars that constrict as the worm struggles, immobilizing it as the fungus’s #hyphae penetrate its body. Some release sickle-shape spores that, when swallowed by a nematode, wreak havoc from within.
