Image Number D1592-1

Close-up view through a fluorescence microscope of a thin cross-section of a barley seed infected with Fusarium graminearum. The seed’s epicarp tissue layer is infected with the Fusarium (seen as fluorescent green). The fungus stops at the testa layer (yellow-orange). It can take 2 weeks or longer before the fungus penetrates into the underlying starchy endosperm of the seed (stained blue). Finding out how to make the epicarp resistant to Fusarium could be the key to making barley resistant.
