Future of Bacterial Disease Management in Crop Production

Abstract: Bacterial diseases are a constant threat to crop production globally. Current management strategies rely on an array of tactics, including improved cultural practices; application of bactericides, plant activators, and biocontrol agents; and use of resistant varieties when available. However, effective management remains a challenge, as the longevity of deployed tactics is threatened by constantly changing bacterial populations. Increased scrutiny of the impact of pesticides on human and environmental health u… Show more

“…Since no executor genes have been identified in citrus plants, we used the bacterial effector gene avrGf2 as a TALE‐inducible executor gene in our transgenic citrus lines. While the integration of foreign DNA into plant genomes suffers from low public acceptance (Sharma et al ., 2022), it is important to note that transcription of this bacterial transgene was found in planta exclusively after infection with TALE gene carrying Xcc strains (Figure 4). Given the superb resistance of our transgenic line to Xcc infection, it is foreseeable that in plantations containing only transgenic trees, the bacterial avrGf2 gene would not actually be transcribed, which should potentially eliminate or reduce public concerns.…”

“…In terms of species and damage degree, plant bacterial disease is a kind of bacterial pathogen disease second only to fungal infection, most of which are caused by Xanthomonas , such as citrus canker, rice bacterial blight, and kiwifruit canker, which can dramatically reduce crop yield, threaten food security, and impact on the global economy. Xanthomonas axonopodis pv. citri ( Xac ) is the main disease of citrus bacterial infection.…”

“…Thus, there is a strong need for new products for bacterial disease control, and specially for the emerging and re-emerging diseases of tree crops ( Sundin et al., 2016 ; Sharma et al., 2022 ). In recent years, the development of biopesticides and particularly non-microbial biopesticides based on natural products are experiencing an increasing growth, as they fulfill the regulations associated to plant protection, such as sustainability, biodegradability and minimal toxicity to humans and environment ( Leahy et al., 2014 ).…”
