Symbiotic yeast helps longicorn beetles to digest wood
Researchers have isolated a symbiotic yeast from adults, larvae, and eggs of the Japanese longicorn beetle and identified specialized organs that store the yeast, allowing the beetles to break down the unpalatable components of wood.

‘Friend or foe’ bacteria kill algal hosts when coexisting no longer works out
A study sheds new light on chemical processes that cause marine bacteria to switch from coexistence with an algae host to killer mode.

Corals may punish cheating symbiont algae by cutting off their food supply
Corals may ‘punish’ the algae that live inside them by cutting off their food supply if such algae become selfish and renege on their part of the resource-sharing deal with the coral as part of their symbiosis.

Two fungi join forces to rampage through fig trees
Researchers have identified a fungus, Fusarium kuroshium, which is harmless by itself, but ravages fig trees when found together with Ceratocystis ficicola, which is transmitted by an ambrosia beetle, Euwallacea interjectus.

Genome studies uncover common ancestor for 600 scattered fungal species
About 600 seemingly disparate fungi that never found a good fit along the fungal family tree have been shown to have a common ancestor, according to a University of Alberta-led research team that used genome sequencing to give these peculiar lifeforms their own taxonomical grouping.
