RNA modifications in plant pathogenic fungi: from epitranscriptomics to antifungal strategies.

Traditional antifungal agents such as polyene, azole, and echinocandin antifungals are restricted because of antifungal resistance and off-target effects. Given these limitations, there is an urgent need to explore novel antifungal strategies by identifying alternative targets. RNA modifications, such as mA, mC, mA, mG, sU, acC, and A-to-I editing, hold promise as such targets on the basis of their roles in post-transcriptional regulation in plant pathogenic fungi, affecting RNA processing, stability, translation, and localization.

CCL22 as a diagnostic and prognostic biomarker for pediatric-onset systemic lupus erythematosus.

Background: Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by diverse symptoms and multisystem involvement. Pediatric-onset systemic lupus erythematosus (pSLE) accounts for 10-20% of all SLE cases and tends to progress more rapidly and severely than adult-onset SLE, making diagnosis more challenging. Current biomarkers remain insufficient in predicting disease severity and organ-specific complications, highlighting the need for new biomarkers.

tRNA thiolation optimizes appressorium-mediated infection by enhancing codon-specific translation in Magnaporthe oryzae.

Thiolation, a post-transcriptional modification catalyzed by Uba4-Urm1-Ncs2/Ncs6 pathway in three specific transfer RNAs (tRNAs), is conserved from yeast to humans and plays an important role in enhancing codon-anticodon interaction and translation efficiency. Yet, except for affecting effector secretion, its roles in plant pathogenic fungi are not fully understood. Here, we used Magnaporthe oryzae as a model system to illustrate the vital role of s2U34 modification on the appressorium-mediated virulence.

Effector secretion and stability in the maize anthracnose pathogen Colletotrichum graminicola requires N-linked protein glycosylation and the ER chaperone pathway.

N-linked protein glycosylation is a conserved and essential modification mediating protein processing and quality control in the endoplasmic reticulum (ER), but how this contributes to the infection cycle of phytopathogenic fungi is largely unknown. In this study, we discovered that inhibition of protein N-glycosylation severely affected vegetative growth, hyphal tip development, conidial germination, appressorium formation, and, ultimately, the ability of the maize (Zea mays) anthracnose pathogen Colletotrichum graminicola to infect its host. Quantitative proteomics analysis showed that N-glycosylation can coordinate protein O-glycosylation, glycosylphosphatidylinositol anchor modification, and endoplasmic reticulum quality control (ERQC) by directly targeting the proteins from the corresponding pathway in the ER.
