Scientists Found a Surprising Way to Make Fungus Happy - The New York Times - 0 views

around Day 3 of the experiment, the fungi treated with sound went into overdrive. T. harzianum spores became bright green in color, and the white noise dishes were soon a mossy viridian. By Day 5, the researchers were able to calculate that exposing the fungi to sound had made them grow seven times as fast and produce more than four times as many spores.

It’s not clear why the sound had these effects. Dr. Robinson speculates that the sound waves may be striking receptors in the fungal cells that are sensitive to pressure. These receptors could then lead to a cascade of signals that switch on growth genes. The researchers plan to look closer at what genes are switched on and off in the presence of sound to help understand the effects.

Why would microbes evolve to grow better in the presence of sound? Perhaps silence indicates a hostile environment, one where no other organism has been able to grow. It might also be that certain kinds of sound fend some microbes off but give off a come-hither vibe to others. The researchers will be experimenting with other sounds and with communities of several microorganisms in future work, so they can better understand the connection between sounds and microbes’ response.
