The RNA-based spray-induced gene silencing (SIGS) technology represents an ecologically sustainable approach to crop protection and pathogen management. Following the recent approval of Ledprona as the first sprayable double-stranded RNA (dsRNA) biopesticide by the EPA at the end of 2023, SIGS has emerged as a focal point in both academic and industrial sectors. This review analyzes recent advances and emerging trends in SIGS. The application of SIGS for crop protection, including the control of insects, fungal pathogens, and viruses, is briefly summarized. Distinguishing this review from others, we delve into practical aspects of the technology, such as the selection and screening of target genes, large-scale production methods, and delivery systems, highlighting major advancements in these areas and also addressing the remaining questions and issues, particularly concerning safety concerns and controlling harmful weeds. Finally, this review emphasizes the emerging trends in SIGS technology, particularly its integration with nanotechnology and other methodologies. Collectively, the rapid progress in SIGS studies is poised to accelerate the maturation and application of this technology.

Through long-term coevolution with host plants, insects have evolved sophisticated detoxification systems to counteract plant secondary metabolites (PSMs). However, the precise mechanisms underlying these adaptations remain incompletely characterized. Our previous research identified epsilon glutathione S-transferases (GSTes) as critical mediators of xanthotoxin adaptation in Spodoptera litura, a model linear furanocoumarin.

Sporulation is the most widespread means of reproduction and dispersal in fungi and, at the same time, an industrially important trait in crop mushrooms. In the Basidiomycota, sexual spores are produced on specialized cells known as basidia, from which they are forcibly discharged with the highest known acceleration in nature. However, the genetics of sporulation remains poorly known.

The large-scale use of nonrenewable plastic mulch has resulted in serious agricultural health pollution. Biobased plastic materials with degradable properties offer attractive sustainable alternatives, but the shortcomings of their properties are slow degradation and extremely monofunctional, making their full-scale promotion still challenging. This work proposes a novel functionalized strategy for the multifunctionality empowerment of bio-based PLA materials for environmental protection and crop yield enhancement.

Pelletization of biomass fuels has been promoted as an effective alternative to mitigate particulate matter (PM) emissions from the residential burning of raw biomass materials; however, environmentally persistent free radicals (EPFRs), a class of harmful components in PM, from the biomass pellet burning have been rarely studied yet. Here, laboratory-based combustion experiments were conducted to characterize EPFRs for different pellets burned in cooking and heating stoves and compared with those for the corresponding uncompressed biofuels. Emission factors (EFs) of EPFRs for biomass pellets ranged from 2.
