FKBP12-4 is required for complete hyphal growth.

<p><b>(A)</b> Growth of <i>A</i>. <i>fumigatus</i> (10⁴ conidia) on GMM at 37°C for 5 days, with colony diameter measured every 24 hours, revealed no statistically significant difference in growth among Δ<i>fkbp12-1</i>, Δ<i>fkbp12-2</i>, Δ<i>fkbp12-1</i>Δ<i>fkbp12-2</i>, Δ<i>fkbp12-3</i> and wild-type strains. Δ<i>fkbp12-4</i> demonstrated reduced growth rate across all 5 days (p = 0.0161). <b>(B)</b> After the 5 day growth period, Δ<i>fkbp12-4</i> demonstrated reduced growth compared to wild-type strain but no other obvious phenotypic abnormalities were noted.
