Main conclusion TobaccoEXPA4plays a role inNicotiana benthamianadefence against virus attack and affects antioxidative metabolism and phytohormone-mediated immunity responses in tobacco.Expansins are cell wall-loosening proteins known for their endogenous functions in cell wall extensibility during plant growth. The effects of expansins on plant growth, developmental processes and environment stress...
Light is an important environment factor controlling plant growth, development, and nutritional quality and is also one of the most important factors inducing plant defence. In this study, we assayed the potential effects of light quality on the interaction between Nicotiana tabacum and cucumber mosaic virus (CMV). Our results indicated that white light‐treated N. tabacum plants displayed obvious...
Key messageThere are significant differences between the DGIs and LGTs. Additionally, most of the characteristics indicate that the DGIs are more similar to recovered tissue and can resist viral attacks. Abstract Dark green islands (DGIs) surrounded by light green tissues (LGTs) are common leaf symptoms of plants that are systemically infected by various mosaic viruses. We performed cytological,...
