Summary: Streptomycetes are potential candidates for the biological control of Fusarium Head Blight in wheat. Previous studies mainly focused on the application of streptomycetes when the wheat plant is mature and close to flowering. This study tested the effects of seed treatment with Streptomyces sp. DEF39 spores before sowing on the development of FHB symptoms and found that it could partially protect wheat from FHB disease.

Summary: This study investigated the aggressiveness of nine Fusarium avenaceum isolates on malting barley and found that the isolates were equally aggressive to barley stems and heads. The isolates caused severe Fusarium seedling blight (FSB) symptoms and produced ENN B as the predominant mycotoxin. Only the most aggressive isolates produced ENN A1 in planta. The cultivar Moonshine showed higher resistance to FSB and Fusarium head blight (FHB) caused by any Fusarium isolate compared to Quench.

Summary: This study isolated 31 endophytic Actinomycetes strains from the roots of Vigna radiata L. and found that one strain, Streptomyces parvulus VRR3, exhibited significant antagonistic activity against Fusarium solani and produced plant growth-promoting agents. Greenhouse experiments demonstrated that S. parvulus VRR3 could promote the growth of green gram plants and reduce the incidence of Fusarium wilt disease.

Summary: In this study, 240 Chinese elite wheat cultivars and lines were evaluated for Fusarium seedling blight (FSB) resistance, with 23 accessions showing potential for FSB resistance breeding. Six stable quantitative trait loci (QTLs) were detected, with four KASP markers identified for marker-assisted selection. Analysis of defense-related genes revealed candidates for mapping QTLs, providing valuable resources for wheat breeding to enhance FSB resistance.

Summary: Research has shown that the mycoparasite Sphaerodes mycoparasitica has a significant impact on the protein and lipid regions, with a connection between carbohydrates and protein regions, involving potential phenolic compounds. Through FTIR analysis, SEM and CLSM observation of fungus-fungus interactions, and PCA analysis, early mycoparasitism can be effectively detected as a vital strategy against plant pathogens.

Summary: Plant diseases caused by phytopathogens are a significant threat to global agricultural systems. Pesticides are effective in controlling plant diseases, but their use is becoming less popular due to their potential harm to humans and the environment. This study explored the biocontrol potential of an endophytic Streptomyces sp. SP5 bioformulations against Fusarium wilt. The bioformulations effectively controlled Fusarium wilt and promoted plant growth and systemic resistance.

Summary: The use of halotolerant beneficial plant-growth-promoting (PGP) bacteria is considered a promising eco-friendly approach to improve salt tolerance in cash crops. This study identified 8 salt-tolerant endophytic bacteria from the roots of Sahara-inhabiting halophytes and found that strain IS26 was the most effective at promoting plant growth and mitigating salt stress in tomato plants. Through genetic analysis, the strain was found to possess various genes related to rhizosphere colonization, plant association, nutrient competition, and the production of important plant growth regulator compounds and stress protection substances. It also had genes related to osmosensing, osmoregulation, osmoprotection, and antioxidant processes. Overall, this strain showed great potential for adaptation to highly saline environments.

Summary: In recent years, various methods have been studied for the extraction of natural carotenoids. Conventional methods often require a large amount of solvents and a lengthy extraction process. However, pressurized liquid extraction has shown promising results. This study focused on the extraction of carotenoids from the green and orange biomasses of microalga Dunaliella salina DunaDZ1 using different organic solvents and temperatures. The results showed that higher temperatures had a positive effect on extraction yield, while the best antioxidant activity was obtained at a specific temperature and with a certain solvent.

Summary: This study focused on the biodiversity of actinobacteria in the Mediterranean Sea habitat. The results showed higher diversity in sediment than in seawater. Through 16S rRNA sequencing, ten different genera were identified, with Streptomyces and Micromonospora being the most dominant. The study also discovered a novel species. Furthermore, 36% of the isolates exhibited antibacterial activity against Gram-positive bacteria. Most strains were found to be halotolerant, but did not require seawater for growth.
