Loss of SrgA impairs conidiation.

<p>A: All three Δ<i>srgA</i> isolates have attenuated conidophores and dysmorphic phialides (normal phialides are shown by the arrow in wt). B: All three Δ<i>srgA</i> isolates release conidia that are heterogeneous in both size and shape. Some of the elongated conidia may be abnormal phialides that are released along with the conidia (arrow) (Scale bar = 20 µm).
