Summary: In this study, the function of ZmMYC7, a putative MYC2 ortholog, in jasmonate-signaled defense responses of maize was investigated. ZmMYC7 was found to play an important role in maize resistance to Fusarium graminearum and Setosphaeria turcica. It regulates the expression of defense-associated genes and interacts with members of the ZmJAZ family and ZmERF147 gene.

Summary: Post-translational modification of proteins, such as lysine 2-hydroxyisobutyrylation (Khib), is crucial for various biological processes. This study identified Khib modification in maize and found that it plays an important role in plant defense against F. graminearum infection by regulating metabolic processes and gene expression. The results provide new insights into plant disease resistance and have implications for molecular breeding in maize.

Summary: This study investigated the effects of temperature on the growth and pathogenicity of F. verticillioides and F. graminearum. The results showed that these two fungal pathogens have different adaptability to different temperatures. RNA-seq analysis revealed distinct gene expression patterns in growth and metabolic pathways under different temperatures for both species.

Summary: This study uncovers the distinct and specific functions of lncRsp1 and Fgsp1 in Fusarium graminearum, showing that lncRsp1 can regulate ascospore discharge by affecting the expression of Fgsp1, with lncRsp1 and Fgsp1 negatively regulating deoxynivalenol biosynthesis genes.

Summary: A-to-I RNA editing is a crucial epigenetic phenomenon for sexual reproduction in fungi. Deciphering the cis-regulatory elements of A-to-I RNA editing can help elucidate the editing mechanism and develop an accurate model for predicting RNA editing.

Summary: Through genome-wide analysis, 103 putative 2OGD genes were identified in maize and divided into three classes - DOXA, DOXB, and DOXC. Among these genes, ACO, F3H, and NCS encoding three 2OGD proteins were induced by Fusarium verticillioides and Fusarium graminearum. The two transcription factors ZmDOF and ZmHSF may also be involved in resistance to these two pathogens.

Summary: This study found that Trichoderma asperellum can effectively inhibit the growth of Fusarium graminearum and increase maize yield by upregulating the expression of defense-related genes and signal transduction pathways, as well as degrading mycotoxins through the upregulation of the UDPglucuronosyltransferase (UGT) gene.

Summary: Bacillus spp. can enhance plant growth and act as a biocontrol agent. This study shows that maize root exudates can recruit Bacillus amyloliquefaciens OR2-30 after Fusarium graminearum infection, and OR2-30 suppresses F. graminearum growth by producing lipopeptides (iturins) to protect maize.

Summary: In this study, we demonstrated for the first time the inhibitory effect of carotenoid extracts from different maize genotypes on TCTB production by F. graminearum. We further suggested that zeaxanthin may play a key role in this inhibition by negatively controlling several biosynthetic genes of the TCTB pathway. Additionally, we showed that zeaxanthin treatments could significantly disrupt the fungal redox homeostasis. These findings highlight the contribution of carotenoids to maize's defense against F. graminearum infection and TCTB production.

Summary: This study revealed that Fusarium graminearum has stage-specific regulation of purine metabolism during infectious growth and sexual reproduction. De novo synthesis of purines is crucial for fungal growth, reproduction, and infection, while salvage synthesis is dispensable for these stages. AMP and GMP have distinct functions in sexual stages, with AMP catabolism playing a specific role in sexual reproduction and pathogenesis.
