APETALA2/ethylene-responsive (AP2/ERF) plays crucial roles in resisting diverse stresses and in regulating plant growth and development. However, little is known regarding the structure and function of the AP2/ERF genes in pearl millet (Pennisetum glaucum). The AP2/ERF gene family may be involved in the development and maintenance of P.

Despite numerous valuable studies on B3 genes in other species, little is known about the B3 superfamily in pearl millet.
Methods And Results: Here, through comparative genomic analysis, we identified 70 B3 proteins in pearl millet and categorized them into four subfamilies based on phylogenetic affiliations: ARF, RAV, LAV, and REM.
Article Synopsis
- Enterovirus G (EV-G) is a member of the Picornaviridae family that infects pigs globally, with 20 genotypes identified, including the newly isolated EV-G/YN29/2022 strain from diarrhea-affected pigs in China.
- This study found that EV-G/YN29/2022 closely resembles the EV-G6 genotype based on genome sequences, with over 83% similarity, marking it as the first EV-G6 strain recorded in China.
- Pathogenicity tests showed that this strain led to mild diarrhea, skin lesions, and weight loss, primarily affecting the intestinal tissues, but also appearing in various organs like the brain and liver, contributing valuable insights into EV-G's epidemiology and evolution.
An aerobic, haemolytic, Gram-negative and rod-shaped bacterial strain ZY171148 was isolated from the lung of a dead goat with respiratory disease in Southwest China. The strain grew at 24-39 °C, at pH 6.0-9.

Recently, recombinant EV-Gs carrying the papain-like cysteine protease (PLCP) gene of porcine torovirus have been isolated or detected, while their pathogenicity is poorly understood. In this study, an EV-G17-PLCP strain, 'EV-G/YN23/2022', was isolated from the feces of pigs with diarrhea, and the virus replicated robustly in numerous cell lines.

- Elephant grass is a low-nutrient, fast-growing forage plant used in tropical regions, and research on transgenic tobacco with a specific gene shows increased drought tolerance.
- Transgenic tobacco exhibited no growth costs while expressing this gene, leading to higher lignin content, antioxidant enzyme activities, and osmotic adjustments.
- The study suggests that overexpressing this gene allows plants to better survive water deficits by redirecting metabolic processes to produce defensive metabolites, potentially aiding in developing drought-resistant crops.
Little is known about the cross talk between the lignin biosynthesis gene promoters and the regulatory proteins that modulate molecular signaling and respond to various stresses. In this study, we characterized the promoter region of the lignin biosynthesis pathway cinnamyl alcohol dehydrogenase (CAD) gene in elephant grass, Pennisetum purpureum. Quantification of the transcript levels of the PpCAD promoter revealed it is preferentially expressed in vascular tissue, especially xylem.
