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. ****  Photo by Ron Skadsen.  640 pixels wide: (d1592-1.jpg)   Please visit our Image Gallery
