Coccidioidomycosis is endemic to the western part of the United States of America, including the central valley of California, Arizona, New Mexico, and parts of western Texas.

The incidence of reported cases of coccidioidomycosis has notably increased since it became reportable in 1995. Clinically, the infection ranges from asymptomatic to fatal disease due to pneumonia or disseminated states. The recognition of coccidioidomycosis can be challenging, as it frequently mimics bacterial community-acquired pneumonia. The diagnosis of coccidioidomycosis is frequently dependent on serologic testing, the results of which can take several days or longer to obtain.

Therefore, this study focused on the <i>mok I</i> gene of <i>Monascus pilosus</i> to construct overexpression strains of the <i>mok I</i> gene, resulting in high-yield MK production.

The UPR helps cells to maintain endoplasmic reticulum (ER) protein homeostasis, which is critical for growth, development, and virulence. The <i>Aspergillus flavus hacA</i> gene encodes a domain rich in basic and acidic amino acids (Bsc) and a basic leucine zipper (bZip) domain, and features a non-conventional intron (Nt20). In this study, CRISPR/Cas9 was utilized to dissect the Bsc-coding, bZip-coding, and Nt20 sequences to elucidate the relationship between genotype and phenotype. In the Bsc and bZip experimental sets, all observed mutations in both coding sequences were in frame, suggesting that out-of-frame mutations are lethal. The survival rate of transformants in the Nt20 experiment set was low, at approximately 7%. Mutations in the intron primarily consisted of out-of-frame insertions and deletions. In addition to the wild-type-like conidial morphology, the mutants exhibited varied colony morphologies, including sclerotial, mixed (conidial and sclerotial), and mycelial morphologies. An ER stress test using dithiothreitol revealed that the sclerotial and mycelial mutants were much more sensitive than the conidial mutants. Additionally, the mycelial mutants were unable to produce aflatoxin but still produced aspergillic acid and kojic acid. RNAi experiments targeting the region encompassing Bsc and bZip indicated that transformant survival rates generally decreased, with a small number of transformants displaying phenotypic changes. Defects in the <i>hacA</i> gene at the DNA and transcript levels affected the survival, growth, and development of <i>A. flavus</i>.
