Summary: In this study, 55 CsDREBs were identified from the cucumber pan-genomes of 13 accessions, with most of them showing variations in sequence length and/or amino acids. Expression pattern analysis revealed specific high expression of different CsDREBs in various cucumber tissues, suggesting their importance in morphogenesis and development. Additionally, different CsDREBs showed differential expression in response to different stresses, with one CsDREB gene responding to all tested stresses. These results provide a basis for further research on the function and mechanism of DREB genes in cucumber resistance breeding.

Summary: In the process of bell pepper (Capsicum annuum) fruit ripening, the conversion from chloroplasts to chromoplasts involves significant changes in the levels of various enzymes, including maintenance of high levels of specific complexes and enzymes, an increase in enzymes related to heterotrophic plastid metabolism, and a shift in abundance of enzymes related to chlorophyll catabolism and carotenoid biosynthesis. Despite these changes, certain proteins remain constant, suggesting a unique metabolic pathway in non-climacteric fruits like bell pepper.

Summary: This study explored the evolutionary relationship and expression patterns of CONSTANS-like (COL) genes in Capsicum annuum. The study identified 10 COL genes in the pepper genome and found that they can be divided into three groups based on gene structure characteristics. The study also showed significant differences in expression patterns of the COL genes in different tissues. Furthermore, the study found that some COL orthologous genes had different expression patterns and were involved in fruit development in pepper compared to tomato. The findings provide a theoretical basis for understanding the functions of COL genes in pepper and their involvement in growth, development, and responses to abiotic stresses.

Summary: As highly conserved signaling pathway modules, mitogen-activated protein kinase (MAPK) cascades play important roles in stress and hormonal responses in plants. In this study, 47 putative Raf-like kinase genes were isolated from the pepper genome and classified into two major categories, B and C. The transcriptional analysis revealed that subgroup B3, C2, C3, and C5 members were significantly induced by osmotic stress, indicating their functional association with osmotic stress response mediated via both ABA-dependent and ABA-independent pathways. These findings contribute to our understanding of the biological functions of CaRaf kinases in plant responses to abiotic stresses.

Summary: Tobacco mosaic disease is a global viral disease that causes significant economic losses. Plant immune inducers, such as ZhiNengCong (ZNC), have been effective in managing viral diseases due to their high efficiency. A sustained release ZNC-based alginate (Alg) called ZNC@Alg was developed, which demonstrated enhanced control effect and growth promotion effect against tobacco mosaic disease. Field experiments showed that ZNC@Alg had a control effect of up to 88%, significantly better than ZNC alone. This study provides a foundation for effective field management of tobacco mosaic disease.

Summary: The use of non-metallic inorganic nanomaterials in antimicrobial photocatalytic technology is important in combating drug-resistant bacteria. In this study, g-C3N4 nanosheets were functionalized onto ZnO nanoparticles using an electrostatic self-assembly approach, resulting in the formation of efficient g-C3N4@ZnO nanoparticle composites. These composites showed enhanced photocatalytic performance and the generation of reactive oxygen species (ROS) compared to g-C3N4 nanosheets. The antibacterial mechanism of g-C3N4@ZnO involves disrupting bacterial membrane synthesis, inhibiting motility and energy metabolism.

Summary: Control of plant virus diseases often relies on synthetic chemical inducers, but the underlying molecular mechanisms are not well understood. In this study, a chitosan-coated lentinan-loaded hydrogel (CSL-gel) was developed and shown to protect plants from various virus infections. The CSL-gel exhibited the ability to sustain release lentinan and promote Ca2+ release. Application of CSL-gels on plant roots induced broad-spectrum resistance against plant viruses. Further analysis revealed that sustained release of Ca2+ from CSL-gel upregulated Nicotiana benthamiana calmodulin-like protein gene 3 (NbCML3), and modulating NbCML3 expression altered tobacco's susceptibility and resistance to TMV.
