Article Synopsis
- - Research on tomatoes has focused on the impact of plant viruses like Tobacco vein banding mosaic virus (TVBMV), which can infect various crops, including tomatoes, and can be transmitted by aphids.
- - In August 2023, about 30% of tomatoes in Dali, Yunnan, exhibited viral disease symptoms, prompting a study where symptomatic leaves were collected and analyzed for pathogens.
- - High-throughput sequencing revealed the presence of TVBMV and chilli veinal mottle virus (ChiVMV) in all nine samples tested, confirming their link to the observed symptoms.

Article Synopsis
- Potato virus H (PVH) was first discovered in potatoes in Inner Mongolia, China and has since been noted to infect other plants like pepino.
- A recent study in Yunnan, China, observed typical viral symptoms in tomato plants during an open field survey, leading to the collection of 11 symptomatic samples for further analysis.
- High-throughput sequencing identified the presence of three viruses in the tomato samples, including PVH, using advanced RNA sequencing techniques and bioinformatics to locate and characterize the pathogens.
Analysis of chloroplast genome characteristics and codon usage bias in 14 species of Annonaceae.

For the study of species evolution, chloroplast gene expression, and transformation, the chloroplast genome is an invaluable resource. Codon usage bias (CUB) analysis is a tool that is utilized to improve gene expression and investigate evolutionary connections in genetic transformation. In this study, we analysed chloroplast genome differences, codon usage patterns and the sources of variation on CUB in 14 Annonaceae species using bioinformatics tools.

The complete genome sequence of a putative novel potyvirus, tentatively named "polygonatum kingianum mottle virus" (PKgMV; GenBank accession no. ON428226), infecting Polygonatum kingianum in China, was obtained by next-generation sequencing (NGS), reverse transcription polymerase chain reaction (RT-PCR), and rapid amplification of cDNA ends (RACE). PKgMV exhibits the typical genome organization and characteristics of members of the genus Potyvirus, with a length of 10,002 nucleotides (nt) and a large open reading frame (nt 108 to 9,746) encoding a polyprotein of 3,212 amino acids (aa) (363.

Unlabelled: The brown planthopper, (Stål) is a major sucking insect pest of rice. This insect has long been considered as migratory; however, its route in India is still unknown. Hence, to find out its migration route genetic diversity, genetic structure and gene flow of 16 populations from major rice growing regions of India was studied based on mitochondrial cytochrome oxidase I (COI).
