<italic>digitatum</italic>
is the most destructive postharvest pathogen of citrus fruits, causing fruit decay and economic loss. Additionally, control of the disease is further complicated by the emergence of drug-resistant strains due to the extensive use of triazole antifungal drugs. In this work, an orthologus gene encoding a putative sterol regulatory element-binding protein (SREBP) was identified in the genome of <italic>P</italic>
. <italic>digitatum</italic>
and named <italic>sreA</italic>
. The putative SreA protein contains a conserved domain of unknown function (DUF2014) at its carboxyl terminus and a helix-loop-helix (HLH) leucine zipper DNA binding domain at its amino terminus, domains that are functionally associated with SREBP transcription factors. The deletion of <italic>sreA</italic>
(ΔsreA) in a prochloraz-resistant strain (PdHS-F6) by <italic>Agrobacterium</italic>
<italic>tumefaciens</italic>
-mediated transformation led to increased susceptibility to prochloraz and a significantly lower EC<sub>50</sub>
value compared with the HS-F6 wild-type or complementation strain (CO<italic>sreA</italic>
). A virulence assay showed that the Δ<italic>sreA</italic>
strain was defective in virulence towards citrus fruits, while the complementation of <italic>sreA</italic>
could restore the virulence to a large extent. Further analysis by quantitative real-time PCR demonstrated that prochloraz-induced expression of <italic>cyp51A</italic>
and <italic>cyp51B</italic>
in PdHS-F6 was completely abolished in the Δ<italic>sreA</italic>
strain. These results demonstrate that <italic>sreA</italic>
is a critical transcription factor gene required for prochloraz resistance and full virulence in <italic>P</italic>
. <italic>digitatum</italic>
and is involved in the regulation of <italic>cyp51</italic>
expression.</p>

<abstract><p><italic>Penicillium</italic>
<italic>digitatum</italic>
is the most destructive postharvest pathogen of citrus fruits, causing fruit decay and economic loss. Additionally, control of the disease is further complicated by the emergence of drug-resistant strains due to the extensive use of triazole antifungal drugs. In this work, an orthologus gene encoding a putative sterol regulatory element-binding protein (SREBP) was identified in the genome of <italic>P</italic>
. <italic>digitatum</italic>
and named <italic>sreA</italic>
. The putative SreA protein contains a conserved domain of unknown function (DUF2014) at its carboxyl terminus and a helix-loop-helix (HLH) leucine zipper DNA binding domain at its amino terminus, domains that are functionally associated with SREBP transcription factors. The deletion of <italic>sreA</italic>
(ΔsreA) in a prochloraz-resistant strain (PdHS-F6) by <italic>Agrobacterium</italic>
<italic>tumefaciens</italic>
-mediated transformation led to increased susceptibility to prochloraz and a significantly lower EC<sub>50</sub>
value compared with the HS-F6 wild-type or complementation strain (CO<italic>sreA</italic>
). A virulence assay showed that the Δ<italic>sreA</italic>
strain was defective in virulence towards citrus fruits, while the complementation of <italic>sreA</italic>
could restore the virulence to a large extent. Further analysis by quantitative real-time PCR demonstrated that prochloraz-induced expression of <italic>cyp51A</italic>
and <italic>cyp51B</italic>
in PdHS-F6 was completely abolished in the Δ<italic>sreA</italic>
strain. These results demonstrate that <italic>sreA</italic>
is a critical transcription factor gene required for prochloraz resistance and full virulence in <italic>P</italic>
. <italic>digitatum</italic>
and is involved in the regulation of <italic>cyp51</italic>
expression.</p>
