Mould fungus, SEM
Mould fungus (Penicillium expansum), coloured scanning electron micrograph (SEM). This fungus, also called blue mould, is a pathogen of plant material, producing the characteristic post-harvest decay of apples and similar fruit. The fruit turn soft and brown, and spores (seen here) are formed that are initially white, and then turn blue. This fungus can have significant effects on fruit production, leading to the use of fungicides to try and control it. Magnification: x1690 when printed at 10 centimetres across

EDITORS COMMENTS
This print showcases the intricate world of mould fungus, specifically Penicillium expansum. Coloured scanning electron micrograph (SEM) technology brings to life the fascinating details of this pathogenic organism that is commonly known as blue mould. As a notorious plant material pathogen, it plays a significant role in post-harvest decay of apples and similar fruits. The image captures the transformative process that occurs when this fungus infects fruit. Initially, the affected areas turn soft and brown, while spores begin to form. In this SEM image, we can observe these spores in their early stages - white in color before gradually turning blue. The impact of Penicillium expansum on fruit production cannot be underestimated. Its ability to cause decay has led farmers and growers to resort to fungicides as a means of control. This microscopic view at x1690 magnification provides valuable insights into its biology and structure. By highlighting the beauty within decay, this photograph reminds us of nature's complex interplay between organisms and their environment. It serves as a reminder that even seemingly insignificant microorganisms can have profound effects on larger ecosystems. Science Photo Library presents this piece not only for its scientific value but also for its aesthetic appeal. It invites viewers to appreciate the intricacies present within our natural world while acknowledging the ongoing efforts made by scientists in understanding and combating crop pathogens like Penicillium expansum.
