Summary: This study found that high expression of SmZIP8 in Salix matsudana can enhance the tolerance of tobacco to Cd stress, reducing cell damage, raising mitotic indices, and reducing chromosome aberration rates. Meanwhile, transgenic tobacco also showed increased photosynthetic capacity and activated antioxidant enzymes, indicating enhanced physiological tolerance to Cd.

Summary: In this study, the JcTAW1 gene from Jatropha curcas was introduced into tobacco, resulting in increased lateral branches and yield of the transgenic plants. The transgenic plants also showed higher plant height, longer roots, and better drought resistance. Transcriptome analysis revealed that JcTAW1 may promote glucose metabolism while suppressing the DNA repair system.

Summary: In maize, fungal-elicited immune responses lead to the production of various sesquiterpenoids and diterpenoids as antibiotics. Through metabolic profiling, a chromosome 1 locus associated with five candidate sesquiterpenoids was identified. Enzyme co-expression studies confirmed the production of specific terpenoids by ZmTPS27 and ZmTPS8. In vitro bioassays showed that the terpenoid cubebol, produced by ZmTPS8, exhibits significant antifungal activity.

Summary: MoSDT1, a transcription factor of rice blast fungus, acts as an inducer to activate defense response in rice mainly by mediating phosphorylated proteins. It plays a crucial role in enhancing rice resistance by modulating defense-related genes, ROS synthesis, callose deposition, PR gene expression, and SA/JA synthesis. MoSDT1 specifically up-regulates the expression levels of phosphorylated proteins involved in stress responses and growth in rice, highlighting its regulatory effects on protein phosphorylation.

Summary: In this study, a salt-inducible NAC gene PsnNAC090 was successfully isolated and found to play an important role in plant development and stress response. Transient transformation experiments confirmed the protein localization in the cell membrane, cytoplasm, and nucleus. Further experiments revealed that PsnNAC090 enhances salt and osmotic tolerance by increasing reactive oxygen species scavenging and reducing lipid peroxide content. These findings suggest that PsnNAC090 is a potential candidate gene for stress response.

Summary: HaNAC3 is a transcriptional activator that may play a role in plant responses to high temperature, high salt, drought, and phytohormone treatments. It enhances the tolerance of transgenic tobacco to abiotic stress and regulates downstream genes and metabolic pathways. This suggests its potential application as a plant tolerance gene.

Summary: Previous studies have shown that brown planthopper (BPH) activates strong local defenses in rice. However, whether a BPH infestation elicits systemic responses in rice is still uncertain. By examining the change in transcript levels of 12 JA and/or SA signaling-responsive marker genes in rice tissues, we found that an infestation of gravid BPH females systemically activates JA- and SA-dependent defenses in rice, which may impact the composition and structure of the rice ecosystem.

Summary: Plant kinases containing the LysM domain, such as OsRLK3 in rice, play crucial roles in pathogen recognition and self-defense reactions. The interaction between OsRLK3 and the novel ATP synthase gene Ab-atps from Aphelenchoides besseyi affects the growth, reproduction, and infection of the nematode, providing insights for controlling A. besseyi.

Summary: This article primarily focuses on the research status of rice's induced defense against the striped stem borer (SSB) from the perspective of immunity. It discusses the important roles played by plant hormones such as jasmonic acid and ethylene, as well as mitogen-activated protein kinases (MAPKs), in the immune response of rice to the SSB. The article also reviews progress in using transgenic technology to study the relationship between rice and the SSB, as well as exploring resistance genes. Lastly, the article discusses prospects for future research on rice's resistance to the SSB.

Summary: Plant defenses against the rice striped stem borer (SSB) are regulated by the jasmonic acid (JA) signaling pathway. However, the symbiotic microbes associated with the SSB larvae interfere with this defense mechanism, suppressing the JA-regulated anti-herbivore defenses in rice plants.
