Phenotype of Δ<i>crn-1</i> mutant.

<p><b>Colony morphology of (A–B) Δ</b><b><i>crn-1</i></b><b> mutant and (C–D) WT strain after 24 and 48 h of incubation on VMM at 28°C.</b> Low magnification images of the colony edge of (E) Δ<i>crn-1</i> mutant and (F) WT strain. Phase contrast images of hypha of (G) Δ<i>crn-1</i> mutant and (H) WT strain. SEM images of (I) the meandering phenotype of Δ<i>crn-1</i> mutant hyphae and (J) the straight WT hyphae. TEM images of the subapical region of 6 h-old germlings of (K) Δ<i>crn-1</i> mutant and (l) WT strain. A comparison of the uneven thickness of the cell wall and the ruffled plasma membrane of the mutant (arrow) with the uniform envelope of the WT (arrowhead). Scale bars = (A–D) 2.5 cm, (E–F) 100 µm, (G–J) 10 µm, (K–L) 1.0 µm.
