Summary: Termites are both keystone species in the ecosystem and pests with significant economic impacts. Scientists are exploring the use of RNAi technology to combat termites, but face challenges due to their social nature and habitats. Genome sequencing projects on termite species offer opportunities for designing RNAi-based termiticides. This perspective highlights existing RNAi-based studies on eusocial termite pests and discusses the prospects for RNAi-termiticides.

Summary: Arthropod pests have the ability to rapidly adapt to new environmental stressors, such as insecticides and climate change. The interaction between epigenetics and genetics helps explain how these adaptations occur. Epigenetic regulation plays a crucial role in governing insecticide resistance and adaptation to climate change by modulating gene expression. This review highlights the importance of recent advancements in understanding epigenetic regulation in insects and their symbiotic microbes, and discusses the potential applications for managing insecticide resistance and pest resilience to climate change.

Summary: In the face of global warming and climate change, plants are subject to various biotic stresses, which hinder their growth and productivity. Nanotechnology, especially the utilization of silicon/silica nanoparticles, has emerged as a sustainable approach to tackle biotic and abiotic constraints in agriculture. These nanoparticles possess unique chemical and optoelectronic properties and can be easily synthesized using different methods for foliar, soil, or seed priming. Once taken up and transported by plants, they promote growth, development, and tolerance against environmental stresses, as well as pest attack and pathogen infection. Si/SiO2NPs not only facilitate nutrient delivery but also enhance plant resistance, making them an eco-friendly and cost-effective option for sustainable agriculture.

Summary: Biotic stresses pose a threat to global food security and crop yield worldwide. Plants respond to these stresses by triggering various adaptive changes, including the synthesis and accumulation of plant secondary metabolites. Transcription factors and miRNAs play crucial roles in regulating the production of these metabolites during stress conditions. This review summarizes the role of stress-inducible TFs in synthesizing and accumulating secondary metabolites and highlights how miRNAs fine-tune the expression of stress-responsive transcription factors during biotic stress.

Summary: The immune response in plants depends on intracellular signalling molecules and involves pathogen recognition, signal perception, and signal transduction. Calcium ions play a crucial role in both PAMP-triggered immunity (PTI) and effector-triggered immunity (ETI), activating various proteins involved in defense signaling. Decoding the calcium ionic map is essential for understanding plant-microbe interactions and defense pathways. This review aims to provide insights into the early sensing of calcium oscillation, signaling events, and mechanistic roles of calcium in plants during pathogen invasion, laying the foundation for future research.

Summary: The Eurasian spruce bark beetle (ESBB) has caused catastrophic damage to Norway spruce forests in Europe, resulting in a significant loss of wood. Traditional forest management strategies have not been effective, and new measures are needed. This study aims to understand the physiology and adaptation of ESBB by analyzing gene expression in different life stages and tissues of the beetle. The findings provide insights into ESBB physiology and adaptation and can be used for future RNAi-based ESBB management.

Summary: This study used comparative proteomics to investigate the digestion and detoxification processes in male and female I. typographus during their callow and sclerotized stages. The differential abundance proteins identified were mainly involved in binding, catalytic activity, anatomical activity, hydrolase activity, metabolic process, and carbohydrate metabolism, which are crucial for growth, digestion, detoxification, and signalling in the beetles. Furthermore, different protein regulation patterns were observed in metabolic and functional processes between the developmental stages of I. typographus.
