Mitigating saturation effects in rice nitrogen estimation using Dualex measurements and machine learning.

Nitrogen is essential for rice growth and yield formation, but traditional methods for assessing nitrogen status are often labor-intensive and unreliable at high nitrogen levels due to saturation effects. This study evaluates the effectiveness of flavonoid content (Flav) and the Nitrogen Balance Index (NBI), measured using a Dualex sensor and combined with machine learning models, for precise nitrogen status estimation in rice. Field experiments involving 15 rice varieties under varying nitrogen application levels collected Dualex measurements of chlorophyll (Chl), Flav, and NBI from the top five leaves at key growth stages.

The transcription factor YbdO attenuates the pathogenicity of avian pathogenic Escherichia coli by regulating oxidative stress response.

Avian pathogenic Escherichia coli (APEC) is a significant pathogen infecting poultry that is responsible for high mortality, morbidity and severe economic losses to the poultry industry globally, posing a substantial risk to the health of poultry. APEC encounters reactive oxygen species (ROS) during the infection process and thus has evolved antioxidant defense mechanisms to protect against oxidative damage. The imbalance of ROS production and antioxidant defenses is known as oxidative stress, which results in oxidative damage to proteins, lipids and DNA, and even bacterial cell death.

Efficient promoter editing of the SBEIIb gene enables fine-tuning of the resistant starch content in rice.

Rice, a staple in diets, undergoes digestion post-consumption, often triggering a swift surge in blood sugar among diabetics, intensifying their health burden. Notably, resistant starch (RS) emerges as a potent ally in fostering satiety and mitigating metabolic syndrome in diabetes. The SBEIIb gene, a key orchestrator of starch branching enzymes, plays a pivotal role in starch synthesis, and its genetic alteration can dramatically boost RS content in rice.

Antimicrobial resistance and virulence factors analysis of a multidrug-resistant Acinetobacter baumannii isolated from chickens using whole-genome sequencing.

Multidrug-resistant (MDR) Acinetobacter baumannii (A. baumannii) is currently recognized not only as a significant nosocomial pathogen but also is an emerging bacterial infection in food-producing animals, posing a critical threat to global health. However, this is a hindrance to detailed bioinformatic studies of MDR A.

miR-184, a downregulated ovary-elevated miRNA transcriptionally activated by SREBF2, exerts anti-apoptotic properties in ovarian granulosa cells through inducing SMAD3 expression.

Follicular atresia is the primary threat to female fertility. miRNAs are dysregulated in granulosa cells (GCs) during follicular atresia, and have emerged as crucial regulators of the initiation and progression of follicular atresia. However, the downregulated ovary-elevated (OE) miRNAs and their biological functions in ovary remain elusive.

Proinflammatory cytokines interleukin-18 and interleukin-6 mediate anorexia induction by trichothecene deoxynivalenol and its congeners.

As the common foodborne mycotoxins with the highest pollution rate, deoxynivalenol (DON, also named "vomitoxin") can harm the health of humans and animals by causing anorectic response. It has four congeners: 3-acetyldeoxynivalenol (3-ADON), 15-acetyldeoxynivalenol (15-ADON), nivalenol (NIV), and fusarenon X (FX). These five mycotoxins have been associated with the detrimental effect on food intake.

TssL2 of T6SS2 is required for mobility, biofilm formation, wrinkly phenotype formation, and virulence of Vibrio parahaemolyticus SH112.

Type VI secretion system 2 (T6SS2) of Vibrio parahaemolyticus is required for cell adhesion and autophagy in macrophages; however, other phenotypes conferred by this T6SS have not been thoroughly investigated. We deleted TssL2, a key component of T6SS2 assembly, to explore the role of the T6SS2 in environmental adaptation and virulence. TssL2 deletion reduced Hcp2 secretion, suggesting that TssL2 played an important role in activity of functional T6SS2.

The Selection of Storage Period for Fresh Rice Noodles, Processing Materials, and the Screening of Key Indicators.

The storage period of paddy is a critical factor affecting rice quality, and it is still unclear how fresh rice noodles, primarily made from paddy, respond to changes in the storage period. To elucidate the relationship between the paddy storage period and the quality of fresh rice noodles, this study used fourteen rice varieties as materials and set up three paddy storage periods (six months, nine months, and twelve months). It explored the quality variation patterns of fresh rice noodles processed from these paddies and analyzed the relationship between the two in conjunction with rice quality.

Identification and Characterization of Linear Epitopes of Monoclonal Antibodies Against African Horse Sickness Virus Serotype 1 VP2 Protein.

African horse sickness (AHS) is an acute, fatal, contagious disease of animals of the family Equidae and is caused by infection with the African horse sickness virus (AHSV). Based on the outer capsid protein VP2, AHSV is classified into nine serotypes (AHSV-1 to -9) with little or no serological cross-reactivity between them. In 2020, AHS outbreaks caused by AHSV-1 were reported in Thailand and Malaysia, marking the first occurrences of AHS in Southeast Asia.

Plant PI4P is required for bacteria to translocate type-3 effectors.

Type-3 effectors (T3E) of phytopathogenic Gram-negative bacteria fulfill a virulent role, causing disease, or an avirulent role, inducing immunity, following their translocation into plant cells. This study aimed to validate the hypothesis that bacterial T3E translocation requires lipidic compounds in plant cell membranes. Based on genetic, molecular, and biochemical assays, we determined that phosphatidylinositol 4-phosphate (PI4P) associated with plant cell membranes is essential for the translocation of T3E by bacterial pathogens.
