Summary: The application of plant growth-promoting microbes can contribute to sustainable agricultural ecosystems. This study found that the addition of Trichoderma bio-organic fertilizer significantly improved crop growth and yield compared to the application of organic fertilizer. The research also showed that fungal communities, rather than bacterial communities, played a crucial role in plant growth promotion.

Summary: In this study, the sensitivity of 255 F. pseudograminearum strains to prothioconazole was determined, with the EC50 values ranging from 0.4228-2.5284 μg/mL. Thirty prothioconazole-resistant mutants were obtained from sensitive parental strains, and these mutants showed defects in vegetative growth, conidia production, and pathogenicity compared to their parental strains. The resistance to prothioconazole in the mutants may be attributed to changes in the relative expression level of Cyp51a and Cyp51b genes.

Summary: Fusarium crown rot is a severe fungal disease that has been spreading in wheat-growing areas in China since 2010. This study found that metconazole, a 14 alpha-demethylation inhibitor fungicide, effectively inhibits the growth and conidial germ tube elongation of Fusarium pseudograminearum, the predominant pathogen causing crown rot in China. Metconazole reduces toxin production and expression levels of toxin biosynthesis genes in F. pseudograminearum. Genome-wide transcriptional profiling revealed changes in gene expression related to ergosterol biosynthesis and ABC transporter-encoding genes in response to metconazole treatment. Greenhouse experiments demonstrated that seed treatment with metconazole significantly reduces crown rot occurrence in wheat.

Summary: This study revealed the mechanism of Fusarium crown rot (FCR) resistance in wheat mediated by the root endophytic fungus Piriformospora indica. The results showed that P. indica colonization significantly reduced the progression of wheat disease, the amount of F. pseudograminearum colonization, and the content of deoxynivalenol (DON) in wheat roots. Transcriptome and metabolomic analysis indicated that P. indica colonization induced the phenylpropanoid pathway, leading to enhanced lignin accumulation and suppression of F. pseudograminearum infection.

Summary: This study evaluates the inhibitory effect of selected strains of Trichoderma viride, T. viridescens, and T. atroviride on the growth and mycotoxin production of Fusarium culmorum and F. cerealis. The results show that Trichoderma strains significantly inhibit the mycelium growth of Fusarium and can colonize the medium surface, grow over the pathogen's mycelium, and sporulate. When co-cultured on rice, Trichoderma strains also exhibit inhibitory effects on the biosynthesis of mycotoxins. Additionally, Trichoderma is capable of glycosylating DON and converting ZEN into its hydroxylated derivative, beta-ZOL.

Summary: This study aimed to identify factors influencing the efficacy of biopesticides against Fusarium wilt in asparagus and assess the efficacy of Trichoderma-based biopesticides under different conditions. The results showed that Trichoderma species inhibited the growth of Fusarium, but high temperatures and limited water availability reduced their efficacy. The findings have implications for selecting appropriate Trichoderma species for specific environmental conditions.

Summary: Recent studies have shown that insect-associated microbes play multiple roles such as lignin degradation, entomopathogen inhibition, and antibiotic production, which improve insect host fitness and offer potential for discovering beneficial microbes for industrial and agricultural applications. This study isolated and identified a total of 74 species of bacteria associated with D. antiqua, showing significant antifungal activity against phytopathogens including Fusarium moniliforme, Botryosphaeria dothidea, and Fusarium oxysporum strains. These bacteria, such as Ochrobactrum anthropi, Morganella morganii, Arthrobacter sp. 3, and Acinetobacter guillouiae, have the potential to be used as biocontrol agents against fungal phytopathogens.

Summary: This study investigated the relationship between the elimination of oxalic acid (OA) by Trichoderma afroharzianum and its antagonistic effects on Botrytis cinerea. The results showed a correlation between OA degradation and mycoparasitism in T. afroharzianum, providing a new perspective on its antagonism against B. cinerea. The study also provided theoretical data for the scientific application of T. afroharzianum in biocontrol.

Summary: A hydrocarbon-degrading bacterium Providencia rettgeri L1 was isolated from Shengli oil field, China, and its petroleum degradation characteristics were investigated. The study found that the strain showed a degradation rate of 45.9% in 14 days, and the degradation rate was accelerated when crude enzymes and formate dehydrogenase were combined. Analysis of the composition of the degraded petroleum showed significant degradation of saturates and aromatics, with different degradation rates for different chain lengths and ring numbers. The study also showed that the bacterium had a rapid proliferation advantage in culture media.

Summary: In this study, a strain of Acinetobacter vivianii KJ-1 capable of degrading diesel was obtained from oil-contaminated soil. After 12 days of incubation, strain KJ-1 was able to degrade over 40% of the diesel. The optimal diesel concentration and nitrogen source concentration for diesel degradation and bacterial growth were 4,140 mg/L and 350-700 mg/L, respectively. The optimal pH range for strain KJ-1 growth and diesel degradation was 6.5-8.0, while the optimal temperature range was 20-37℃. The analysis of the strain's complete genome revealed the potential mechanisms involved in diesel degradation. This study suggests that A. vivianii KJ-1 may be a useful candidate for bioremediation of diesel-polluted soil.

Summary: Long coleoptile (LC) - wheat genotypes, sown deeper than current practice, enable earlier deep sowing into subsurface soil moisture. The LC genotype shows promise to broaden sowing windows and remove reliance on the shifting seasonal break for crop establishment. Investigation is needed to identify suitable environments for potential establishment benefits in the highly variable soils of the southern Australian wheatbelt.

Summary: Pesticide resistance causes significant economic losses globally each year. Previous research has mainly focused on investigating the interactions between resistant pests and associated microbes, with a lack of quantification on the individual contributions of the pest host and associated microbes to resistance. This study compares resistant and sensitive strains and uses metaproteomics to analyze protein profiles, revealing contributions by the pest and its gut bacteria to phoxim resistance.
