Quercetin glycosylation and hydrolysis mediate a biochemical arms race between apple and herbivorous insects

Jing Xu, Shanshan Zhao, Xiaoping Zhu, Fengwang Ma et autres

Quercetin glycosides are abundant flavonoids in apple (Malus domestica) leaves; however, how their structural variation shapes plant-insect interactions remain unclear. Here, we show that quercetin glycosylation and hydrolysis underlie a biochemical arms race between apple and multiple herbivorous insects. Herbivory by Helicoverpa …

Integrated transcriptomics, proteomics, and metabolomics analyses reveal key regulatory pathways related to the development of viral symptoms in tomato plants

Kaijie Shang, Lianyi Zang, Qian Zhao, Xuli Gao et autres

BACKGROUND: Viral infections of tomato plants present a significant threat to tomato production and yield. Mixed viral infections are common in field-grown tomatoes and are known to exacerbate disease symptoms; however, the molecular mechanisms affecting symptom severity remain poorly understood. This study …

Tomato antiviral ubiquitin-proteasome system recognizes viral 59 kDa protein to confer tomato chlorosis virus resistance

Dan Zhao, Xiaoqian Liu, Hongbo Li, Tianchen Xia et autres

Viral diseases critically impact crop yields, necessitating insights into plant-pathogen recognition and resistance. In tomato (Solanum lycopersicum), tomato chlorosis virus (ToCV) employs 59 kDa protein (p59) to facilitate movement and degrade the host Catalase1 (SlCAT1), disrupting redox homeostasis. Importantly, tomato has evolved …

Chloroplast Fibrillin‐Mediated α‐Tocopherol Biosynthesis Impaired by a Virus to Enhance Infection and to Improve Drought Tolerance

Sijia Liu, Xuedong Liu, Xi Chen, Lianyi Zang et autres

Plastoglobules (PGs), the lipid droplets mainly within chloroplasts, are crucial for plant redox homeostasis and environmental adaptation. However, the regulation of PG under stress remains elusive. This study uncovers that PGs are targeted by the p22 protein encoded by an emerging virus-tomato …

Pathogenicity factor p22 of tomato chlorosis virus interferes with abscisic acid‐mediated antiviral defenses by disrupting the function of WRKY81 in tomato

Lianyi Zang, Pei Wang, Sijia Liu, Mu Xiao et autres

Abscisic acid (ABA) is essential for plant resistance to both biotic and abiotic stresses, but its regulation during virus infection and role in antiviral defense remain poorly understood. Here, we report that overexpression of SlWRKY81 led to increased ABA accumulation, whereas silencing …

Silencing suppressors of rice black‐streaked dwarf virus and rice stripe virus hijack the 26S proteasome of Laodelphax striatellus to facilitate virus accumulation and transmission

Ying Li, Lifei Zhu, Jiaqi Gao, Haoran Ma et autres

BACKGROUND: Rice black-streaked dwarf virus (RBSDV) is transmitted by small brown planthopper (Laodelphax striatellus [L. striatellus]) and causes devastating disease in rice. P9-1 has silencing suppression activity and is the key protein for viroplasm formation in RBSDV-infected plants and insects; however, its …
