Abstract

Metarhiziun acridum is an entomopathogen currently used against acridids. We have previously reported that exposing mycelium to visible light increases M. acridum tolerance to ultraviolet-B (UV-B) radiation. Here we evaluated if light could also increase tolerance to ultraviolet-C (UV-C) radiation. We observed that, as opposed to UV-B radiation, light did not increase tolerance to UV-C radiation under dark repair conditions. However, light did increase tolerance to UV-C radiation if photoreactivating light was present after UV-C exposure. Quantitative PCR experiments revealed that light up-regulates a photolyase gene. This is the first report showing that light regulates photoreactivating ability in M. acridum. (AU)
