“…Potato (Solanum tuberosum L.) is the fourth-largest food crop globally and serves as a vital food source for humans, following wheat (Triticum aestivum L.), rice (Oryza sativa L.), and corn (Zea mays L.). 1,2 It constitutes a significant reservoir of antioxidants in the human diet, offering dietary fiber, carbohydrates, vitamins, and an array of essential minerals, including potassium, phosphorus, magnesium, calcium, iron, and zinc. 3,4 In 2022, the worldwide potato cultivation area reached 16.49 million hectares, yielding 359.07 million tons.…”

BACKGROUNDPotatoes, a major economic crop, are significantly impacted by Fusarium dry rot, a prevalent postharvest disease. Despite the broad‐spectrum antimicrobial properties of cinnamaldehyde, a naturally‐derived plant substance, its efficacy against the causal pathogen of potato dry rot (Fusarium oxysporum) and the underlying mechanisms have not been extensively studied.RESULTSOur study demonstrates that cinnamaldehyde effectively inhibits the growth of Fusarium oxysporum, the pathogen responsible for potato dry rot, and increases its sensitivity to environmental stress factors such as extreme temperatures and high salt stress. Treatment with cinnamaldehyde results in altered fungal mycelium morphology, compromised cell wall stability, and disrupted cell membrane integrity, thereby reducing spore viability. Specifically, it interferes with the cell membrane and cell wall structures of the fungus, potentially disrupting fungal growth by modulating signaling pathways involved in cell wall maintenance, chitin metabolism, and GPI‐anchored protein function. Notably, we show that cinnamaldehyde induces a form of regulated cell death in F. oxysporum, which is characterized not as typical apoptosis, as evidenced by Annexin V negative staining. However, the specific cell death type and underlying mechanism still needed to be further explored.CONCLUSIONCinnamaldehyde, an environmentally friendly plant‐based active compound, exhibits strong inhibitory effects on F. oxysporum, indicating its potential use in the prevention and control strategies for potato dry rot. This research contributes to the understanding of novel antifungal mechanisms and offers promising insights into eco‐friendly alternatives for managing this economically significant postharvest disease.This article is protected by copyright.

“…Potato is rich in plenty of macronutrients (such as carbohydrates and dietary fibre) and micronutrients (such as vitamins and minerals); furthermore, it is also an important source of antioxidants in people's diet [1]. It is reported that, in 2020, the total world production of potatoes was 359 million tonness (http://www.fao.org/faostat/en/ ?#data/QC, accessed on 1 January 2021) and China ranked the first with the production of 17.98 million tons [2,3]. More than 85% of potatoes need to be kept for 3-6 months as a vegetable and industrial material, and the losses due to the disease during storage are very large [4].…”

Fusarium dry rot is one of the major potato diseases during storage after harvest, which not only results in quality degradation but also causes great economic losses. The disease can be elicited by some species of Fusarium, and the pathogenic fungi of Fusarium causing potato dry rot are considerably diverse in various countries and regions. The disease caused by Fusarium spp. is associated with mycotoxins accumulation, which has phytotoxic and mycotoxic effects on humans and animals. Chemical synthetic fungicide is considered the main control measure for the Fusarium dry rot of potato; nevertheless, it is unfortunate that persistent application inevitably results in the emergency of a resistant strain and environmental contamination. A comprehensive disease control strategy includes potato cultivar selection, appropriate cultural practices (crop rotation, cultivate pattern, fertilization, and irrigation), harvesting processes and postharvest treatments (harvesting, classification, packaging, wound healing), and storage conditions (environmental disinfection, temperature, humidity and gas composition) along with the application of fungicide pre-harvest or post-harvest. Recently, emerging studies have indicated that eco-friendly strategies include physical control, chemical methods (such as the application of generally-recognised-as-safe (GRAS) compounds or chemical (elicitors) and biological control have been introduced to combat the Fusarium dry rot of potato.
