Cucurbit-infecting tobamoviruses known so far belong to six acknowledged or tentative species. Except for cucumber green mottle mosaic virus (CGMMV), which is present worldwide, they are geographically restricted, mostly Asia, and have not been observed in Africa far. A tobamovirus isolate infecting a wild Coccinia grandis plant was collected central Sudan 2012. Its host range appeared be limit...

The genus Tobamovirus comprises a group of single-stranded RNA viruses that affect wide variety vegetables economic importance. Tobamoviruses express series proteins interact with the plant’s cellular machinery, allowing viral infection; during incompatible interactions, active defense is mediated by host encoded resistance genes. genes conferring and tolerance in non-susceptible hosts have bee...

Tomato brown rugose fruit virus (ToBRFV) is an emerging tobamovirus infecting tomato and pepper crops. First identified in 2014 the Middle East, ToBRFV has spread rapidly around world. Being seed-borne, resistance breaking easy mechanical transmission, can quickly a greenhouse through plant handling. Thus, selecting effective disinfectant that capable of deactivating infectivity important. We a...

There is a growing realization that a modern combination of molecular biology and agriculture will provide a photosynthetic basis for the biosynthesis of an increasing variety of complex and valuable molecules. This 'greening' of biotechnology may impact on the global environment in many beneficial ways, but will perhaps have its most significant impact on human health. In the past decade, the ...

Pti4 is a tomato (Lycopersicon esculentum) transcription factor that belongs to the ERF (ethylene-responsive element binding factor) family of proteins. It interacts with the Pto kinase in tomato, which confers resistance to the Pseudomonas syringae pv tomato pathogen that causes bacterial speck disease. To study the function of Pti4, transgenic Arabidopsis plants were generated that expressed ...

Due to the dense distribution of tomato fruit with similar morphologies and colors, it is difficult recognize maturity stages when harvested. In this study, a recognition model, YOLOv5s-tomato, proposed based on improved YOLOv5 four types different stages: mature green, breaker, pink, red. Tomato datasets were established using images collected at maturing in greenhouse. The small-target detect...
