Among the large cast of microbiome players, bacteria have long been hogging the spotlight. But the single-celled organisms known as protists are finally getting the starring role they deserve.
A group of scientists who study the interactions between plants and microbes have released a new study detailing the dynamic relationships between soil-dwelling protists and developing plants, demonstrating that soil protists respond to plant signals much like bacteria do.
An enormous variety and diversity of microbes live in soil, and studying how these organisms interact with each other and with plant roots is a hot topic in biology, as it has applications for agriculture, land stewardship, and climate change resilience technologies.

Imagine there are arrows that are lethal when fired on your enemies yet harmless if they fall on your friends. It s easy to see how these would be an amazing advantage in warfare, if they were real. However, something just like these arrows does indeed exist, and they are used in warfare . just on a different scale.
These weapons are called tailocins, and the reality is almost stranger than fiction. Tailocins are extremely strong protein nanomachines made by bacteria, explained Vivek Mutalik, a research scientist at Lawrence Berkeley National Laboratory (Berkeley Lab) who studies tailocins and phages, the bacteria-infecting viruses that tailocins appear to be remnants of. They look like phages but they don t have the capsid, which is the head of the phage that contains the viral DNA and replication machinery. So, they re like a sprin
