| contents | Transcriptomic investigation reveals a potential mechanism of white LED irradiation inhibiting the growth and pathogenicity of the blue mold pathogen Penicillium expansum. Cai, Yiliang Shan, Jingjing Mao, Xinyu Zhang, Zihan Hong, Wei Wang, Weilun Zhao, Chao Lin, Haiyan Zhu, Ruiyu Penicillium Malus Plant Diseases Light Fruit Gene Expression Profiling Transcriptome Virulence Fungal Proteins Food Irradiation Gene Expression Regulation, Fungal LED visible light irradiation demonstrates significant potential for suppressing postharvest pathogens, yet the antifungal efficacy and underlying mechanisms of white light spectrum remain poorly understood. This study systematically evaluated the inhibitory effects of two white LED irradiation intensities (40 and 120 μmol m s) against Penicillium expansum through in vitro and in vivo trials, with darkness as the control, while elucidating the mechanistic basis via transcriptomic profiling. In vitro experiments revealed that white LED irradiation effectively suppressed fungal growth and induced substantial disruption of cell membrane integrity. In vivo applications demonstrated that 120 μmol m s irradiation significantly attenuated P. expansum pathogenicity on apple fruits while maintaining optimal fruit quality parameters. Transcriptomic analysis identified irradiation-induced dysregulation of key metabolic pathways, including carbohydrate and lipid metabolism, coupled with impaired cell membrane functionality of P. expansum. We propose a tripartite inhibitory mechanism involving the suppression of energy supply, structural destabilization of cellular membranes, and reduction of virulence factor secretion in P. expansum exposed to 120 μmol m s white LED irradiation. These findings elucidated the effect and mechanism of white light irradiation in inhibiting the growth of P. expansum, demonstrating white LED's potential as an eco-friendly, cost-effective preservation strategy for postharvest apple management. |
