Infection assays with flowering wheat heads and corn silks.

Abstract

<p><b>A.</b> Flowering wheat heads were drop-inoculated with conidia from the wild-type (PH-1), Δ<i>amt1</i> mutant (M2), and Δ<i>amt1/AMT1</i> (C2) strains. Black dots mark the inoculated spikeletes. Photographs were taken 14 days post-inoculation (dpi). <b>B.</b> Corn silks were inoculated with blocks of cultures of PH-1, Δ<i>amt1</i> mutant M2, and Δ<i>amt1/AMT1</i> transformant C2. Photographs were taken 6 dpi.</p
