Abstract
Fusarium oxysporum f. sp. cucumerinum (Foc) is a prominent pathogen that adversely affects cucumber (Cucumis sativus) production. In the pathogen's parasitic lifestyle, the pathogenesis and virulence evolution may be regulated by lysine acetylation, as demonstrated in many living organisms. However, its specific function in Foc remains poorly understood. In this study, the acetylome profiles of a mild virulence strain (foc-3b) and its derived virulence-enhanced strain (Ra-4) were analyzed before and post-inoculation on cucumber plants. In total, 10,664 acetylation sites were identified corresponding to 3874 proteins, and 45 conserved acetylation motifs were detected. Through comparison of the acetylomes, numerous differentially lysine-acetylated proteins were enriched in energy metabolism and protein processing processes, indicating the critical role of lysine acetylation during the transition from the saprotrophic lifestyle to the parasitic lifestyle. Comparative acetylome analyses on the two virulence-differentiated strains revealed that several differentially lysine-acetylated proteins were involved in pathways of defense response and energy metabolism. Ra-4 showed enhanced energy metabolism compared to foc-3b. This indicates that robust metabolic activity is required to achieve high virulence and facilitating adaptive evolution. Additionally, faster host responses are supported by an ample energy supply enhancing virulence. Thus, lysine acetylation plays a crucial role in the pathogenesis and virulence evolution of Foc.

Abstract
Lysine acetylation (Kac) is an important post-translational modification (PTM) of proteins in all organisms, but its functions have not been extensively explored in filamentous fungi. In this study, a Tandem Mass Tag (TMT) labelling lysine acetylome was constructed, and differentially modified Kac proteins were quantified during mycoparasitism and vegetative growth in the biocontrol fungus Clonostachys chloroleuca 67–1, using liquid chromatography-tandem mass spectrometry (LC–MS/MS). A total of 1448 Kac sites were detected on 740 Kac proteins, among which 126 sites on 103 proteins were differentially regulated. Systematic bioinformatics analyses indicate that the modified Kac proteins were from multiple subcellular localizations and involved in diverse functions including chromatin assembly, glycometabolism and redox activities. All Kac sites were characterized by 10 motifs, including the novel CxxKac motif. The results suggest that Kac proteins may have effects of broadly regulating protein interaction networks during C. chloroleuca parasitism to Sclerotinia sclerotiorum sclerotia. This is the first report of a correlation between Kac events and the biocontrol activity of C. chloroleuca. Our findings provide insight into the molecular mechanisms underlying C. chloroleuca control of plant fungal pathogens regulated by Kac proteins.

Abstract
In recent years, the intensification of the use of immunosuppressive therapies has increased the incidence of invasive infections caused by opportunistic fungi. Considering that, the spread of azole resistance and amphotericin B (AmB) inefficiency against some clinical and environmental isolates has been described. Thus, to avoid a global problem when controlling fungal infections and critical failures in medicine, and food security, new approaches for drug target identification and for the development of new treatments that are more effective against pathogenic fungi are desired. Recent studies indicate that protein acetylation is present in hundreds of proteins of different cellular compartments and is involved in several biological processes, i.e., metabolism, translation, gene expression regulation, and oxidative stress response, from prokaryotes and eukaryotes, including fungi, demonstrating that lysine acetylation plays an important role in essential mechanisms. Lysine acetyltransferases (KATs) and lysine deacetylases (KDACs), the two enzyme families responsible for regulating protein acetylation levels, have been explored as drug targets for the treatment of several human diseases and infections. Aspergilli have on average 8 KAT genes and 11 KDAC genes in their genomes. This review aims to summarize the available knowledge about Aspergillus spp. azole resistance mechanisms and the role of lysine acetylation in the control of biological processes in fungi. We also want to discuss the lysine acetylation as a potential target for fungal infection treatment and drug target discovery.

Abstract
Ubi4 is a polyubiquitin precursor well characterized in yeasts but unexplored in insect mycopathogens. Here, we report that orthologous Ubi4 plays a core role in ubiquitin- and asexual lifestyle-required cellular events in Beauveria bassiana. Deletion of ubi4 led to abolished ubiquitin accumulation, blocked autophagic process, severe defects in conidiation and conidial quality, reduced cell tolerance to oxidative, osmotic, cell wall perturbing and heat-shock stresses, decreased transcript levels of development-activating and antioxidant genes, but light effect on radial growth under normal conditions. The deletion mutant lost insect pathogenicity via normal cuticle infection and was severely compromised in virulence via cuticle-bypassing infection due to a block of dimorphic transition critical for acceleration of host mummification. Proteomic and ubiquitylomic analyses revealed 1081 proteins differentially expressed and 639 lysine residues significantly hyper- or hypo-ubiquitylated in the deletion mutant, including dozens of ubiquitin-activating, conjugating and ligating enzymes, core histones, and many more involved in proteasomes, autophagy-lysosome process and protein degradation. Singular deletions of seven ubiquitin-conjugating enzyme genes exerted differential Ubi4-like effects on conidiation level and conidial traits. These findings uncover an essential role of Ubi4 in ubiquitin transfer cascade and its pleiotropic effects on the in vitro and in vivo asexual cycle of B. bassiana.

Abstract
Lysine (K)-specific demethylase 2B (KDM2B) has been testified to be an oncogene in diverse cancers, which joins in mediating the carcinogenesis of cancers. Nonetheless, the function of KDM2B in colon cancer remains unexplored. The study attempted to disclose the influences of KDM2B acetylation in the progression of colon cancer. SW48 and SUN-C1 cells were transfected with Flag-KDM2B and administrated by trichostatin A and nicotinamide for 24 hr. Immunoprecipitation with a Flag antibody followed by western blot with acetyl-lysine-specific antibody was executed to detect KDM2B acetylation. The correlation between CREB binding protein (CBP) and KDM2B was then investigated. The K-R and K-Q mutants were constructed and the impacts of KDM2B on demethylation of nucleosomal substrates, p21, and puma transcription and the carcinogenesis of colon cancer were probed. CBP immediately evoked KDM2B acetylation at lysine residue 765 in colon cancer cells. Acetylation of KDM2B obviously destroyed the relevance with nucleosomes, demethylation of nucleosomal substrates, and repressed p21 and puma transcription. More important, KDM2B acetylation restrained SUN-C1 cells proliferation and colony formation, meanwhile, hindered cell migration and invasion. Beyond that, the tumor formation was repressed by KDM2B acetylation. The observations testified that CBP-triggered KDM2B acetylation accelerated the carcinogenesis of colon cancer.

Abstract
Rpd3 is a class I histone deacetylase that reverses lysine acetylation thus influencing cellular processes and functions. However, its role in fungal insect pathogens has not been explored yet. Here we show that Rpd3-dependent lysine modification and gene expression orchestrate growth, conidiation and virulence in Beauveria bassiana. Deletion of Rpd3 resulted in severe growth defects on various carbon/nitrogen sources, 97% reduction in conidiation capacity and drastic attenuation in virulence. These phenotypes concurred with differential expression of 1479 proteins and hyperacetylation or hypoacetylation of 2227 lysine residues on 1134 proteins. Many of these proteins fell into carbon/nitrogen metabolism and cell rescue/defence/virulence, indicating vital roles of Rpd3-dependent protein expression and lysine modification in the fungal growth and virulence. Intriguingly, lysine residues of four core histones (H2A, H2B, H3 and H4) and many histone acetyltransferases were also hyper- or hypoacetylated in Δrpd3, suggesting direct and indirect roles for Rpd3 in genome-wide lysine modification. However, crucial development activators were transcriptionally repressed and not found in either proteome or acetylome. Single/double-site-directed H3K9/K14 mutations for hyper/hypoacetylation exerted significant impacts on conidiation and dimorphic transition crucial for fungal virulence. Altogether, Rpd3 mediates growth, asexual development and virulence through transcriptional/translational regulation and posttranslational lysine modification in B. bassiana.

Abstract
Lysine acetylation is a dynamic and highly conserved post-translational modification that plays a critical role in regulating diverse cellular processes. Trichinella spiralis is a foodborne parasite with a considerable socio-economic impact. However, to date, little is known regarding the role of lysine acetylation in this parasitic nematode. In this study, we utilized a proteomic approach involving anti-acetyl lysine-based enrichment and highly sensitive mass spectrometry to identify the global acetylated proteome and investigate lysine acetylation in T. spiralis. In total, 3872 lysine modification sites were identified in 1592 proteins that are involved in a wide variety of biological processes. Consistent with the results of previous studies, a large number of the acetylated proteins appear to be involved in metabolic and biosynthetic processes. Interestingly, according to the functional enrichment analysis, 29 acetylated proteins were associated with phagocytosis, suggesting an important role of lysine acetylation in this process. Among the identified proteins, 15 putative acetylation motifs were detected. The presence of serine downstream of the lysine acetylation site was commonly observed in the regions surrounding the sites. Moreover, protein interaction network analysis revealed that various interactions are regulated by protein acetylation. These data represent the first report of the acetylome of T. spiralis and provide an important resource for further explorations of the role of lysine acetylation in this foodborne pathogen.
