Helotiales, a diverse fungal order within Leotiomycetes (Ascomycota), comprises over 6000 species occupying varied ecological niches, from plant pathogens to saprobes and symbionts. Despite their importance, their genetic adaptations to temperature and environmental conditions are understudied. This study investigates temperature adaptations in infection genes and substrate degradation genes through a comparative genomics analysis of 129 Helotiales species, using the newly sequenced genomes of Gyoerffyella rotula and Anguillospora crassa. Key gene families such as cytochrome P450 enzymes, virulence factors, effector proteins, and carbohydrate-active enzymes (CAZymes) were analyzed to understand their roles in temperature and lifestyle adaptations, uncovering possible alternative lifestyle mechanisms. Our findings reveal that Helotiales fungi possess genes associated with nutrient acquisition, pathogenicity, and symbiotic relationships strongly adapted to cold environments that might be impacted by global warming. On the other hand, some species demonstrate potential for adaptation to warmer climates, suggesting increased activity in response to global warming. This study reveals the adaptive mechanisms enabling Helotiales fungi to thrive in both cold and warm environments. These findings provide valuable insights into their ecological success and evolutionary resilience, which may facilitate their ability to transition between pathogenic, symbiotic, and saprobic phases in response to changing environmental conditions.

Soil-borne diseases are exacerbated by continuous cropping and negatively impact maize health and yields. We conducted a long-term (11-year) field experiment in the black soil region of Northeast China to analyze the effects of different cropping systems on maize yield and rhizosphere soil fungal community structure and function. The experiment included three cropping systems: continuous maize cropping (CMC), maize–soybean rotation (MSR), and maize–soybean intercropping (MSI). MSI and MSR resulted in a 3.30–16.26% lower ear height coefficient and a 7.43–12.37% higher maize yield compared to CMC. The richness and diversity of rhizosphere soil fungi were 7.75–20.26% lower in MSI and MSR than in CMC. The relative abundances of Tausonia and Mortierella were associated with increased maize yield, whereas the relative abundance of Solicoccozyma was associated with decreased maize yield. MSI and MSR had higher proportions of wood saprotrophs and lower proportions of plant pathogens than CMC. Furthermore, our findings indicate that crop rotation is more effective than intercropping for enhancing maize yield and mitigating soil-borne diseases in the black soil zone of Northeast China. This study offers valuable insights for the development of sustainable agroecosystems.
