Photomicrograph of wheat rust (Puccinia graminis) urediniospores on a wheat leaf, mag. 70x (at 24 x 36 mm). P. graminis is heteroecious, spending part of its life cycle on wheat and part on barberry. A uredinium (center) on the wheat leaf contains unicellular, dikaryotic urediniospores produced throughout the summer that reinfect the wheat. (c) Herve Conge
