Summary: Male fertility is crucial for animal reproduction and population growth. Seminal Fluid Proteins (SFPs) are important components of male ejaculate that influence male fertility, sperm activation, and female ovulation. This study focuses on the Serine protease 2 (Ser2) gene in the lepidopteran pest Spodoptera litura and demonstrates its importance in SFPs. The findings provide insights into pest control and potential new strategies for the management of lepidopteran insect pests.

Summary: The study revealed that low concentration rotenone treatment led to aggregation of Spodoptera litura cells (SL-1), while high concentration did not. This aggregation phenomenon resulted in cell squeezing each other, which caused destruction of cell membrane structure and function.

Summary: The bistrifluron-resistant strain showed significantly higher oviposition and egg production compared to the susceptible strain, and had elongated ovariole length. This resistance was correlated with up-regulation of chitin synthase A and a mutation in its catalytic domain, leading to higher chitin content. Recovery of sensitivity to bistrifluron was observed when chitin synthase A was knocked down through RNA interference.

Summary: The study found that low-dose ionizing radiation can be used as a radiation hormesis treatment to improve the quality of laboratory-reared Spodoptera litura moths. This can enhance the viability and competitiveness of released sterile moths and increase the efficiency of the inherited sterility technique for managing lepidopteran pests.

Summary: Three pairs of undescribed enantiomeric alpha-pymne derivatives and six undescribed congeners were isolated from the fungus Alternaria brassicicola. These compounds were evaluated for herbicidal activity against various weeds, showing promising results comparable to the positive control glyphosate. The study provides insights on the structure-herbicidal activity relationship and opens up opportunities for the practical application of fungal metabolites as ecofriendly herbicides.

Summary: In this study, the efficiency of the endophytic fungal isolate Msh5 on promoting tomato plant growth and controlling Alternaria alternata was evaluated. The results showed that Msh5 was capable of producing beneficial substances and inhibiting the growth of A. alternata. Under laboratory conditions, Msh5 could reduce spore germination and alter the hyphal structure of A. alternata. In plant experiments, Msh5 significantly increased plant growth and reduced diseases caused by A. alternata.

Summary: This study investigates the use of endophytic entomopathogenic fungi (EPF) to control Spodoptera litura, a common pest in tomato crops. The results show that colonization by an indigenous EPF strain leads to increased mortality in the insect larvae, as well as abnormal growth and developmental processes. The EPF strain is found to survive in different plant parts and can be vertically transmitted to progenies via seeds. This study suggests that inoculating endophytic EPF into seeds or seedlings could be an effective and sustainable approach for pest management in horticulture crops.

Summary: Seven undescribed polyketides with unique structures were isolated from Rhodiola tibetica endophytic fungus Alternaria sp. HJT-Y7. The structures of these compounds were determined using NMR and HR-ESI-MS analysis. Two undescribed compounds and four known compounds demonstrated significant inhibitory effects on LPS-induced NO production in cells without cytotoxicity.

Summary: The study isolated endophytic basidiomycetous fungi and evaluated their antidiabetic potential in-vitro and in-vivo. Results showed that ethyl acetate extract of S. commune exhibited significant antidiabetic effects in diabetic rats, improving blood glucose levels, renal parameters, lipid profile, antioxidant parameters, and liver enzymes. Phytochemical analysis revealed the presence of phenolics and terpenoids in the extract. This study highlights the therapeutic potential of endophytic S. commune in managing diabetes.

Summary: Peptidyl-prolyl cis-trans isomerases (PPIases) are enzymes capable of cis-trans isomerization of the prolyl peptide bond, playing essential roles in various cellular processes. This study conducted a genome-wide analysis of PPIases in different Penicillium spp. and found variations in gene numbers and activities under salt stress. The halotolerant strain P. oxalicum showed significant enhancement in mycelial PPIase activity under salt stress, suggesting the importance of these enzymes in salt stress adaptation.
