Cellular Partners of Tobamoviral Movement Proteins.

Vavilov Institute of General Genetics Russian Academy of Sciences, 119333 Moscow, Russia.
The size of viral genomes is limited, thus the majority of encoded proteins possess multiple functions. The main function of tobamoviral movement protein (MP) is to perform plasmodesmata gating and mediate intercellular transport of the viral RNA. MP is a remarkable example of a protein that, in addition to the initially discovered and most obvious function, carries out numerous activities that are important both for the manifestation of its key function and for successful and productive infection in general.

Aims: The aim of this study was to evaluate the impact of the introduction of a phosphoribosylpyrophosphate synthetase (PRS) mutation into a plant growth-promoting strain of Methylorubrum on the enhancement of phyllosphere colonization, with the ultimate goal of improving plant growth and quality.
Methods And Results: A strain of Methylorubrum populi (named HS04) was isolated from the groundnut leave and found to process the plant-promoting traits, including the ability to produce indole acetic acid, siderophore, 1-aminocyclopropane-1- carboxylate deaminase, and to fix nitrogen. The application via foliar spray significantly increased the fresh weight of cucumber seedlings cultivated in a standard growth chamber, with 43.
First Report of Causing Leaf Spot on in a greenhouse in New York State, U.S.A.

Article Synopsis
- The Chinese hibiscus is a popular decorative and medicinal plant, but it is vulnerable to various bacterial infections.
- In March 2019, a bacterial isolate named "Hibiscus 35-1" was identified from affected hibiscus plants in a New York greenhouse, showing leaf spots and chlorosis after being moved from Florida.
- Experiments confirmed the pathogenicity of "Hibiscus 35-1," causing symptoms in inoculated hibiscus plants while control plants showed no symptoms, highlighting the significance of bacterial pathogens in ornamental horticulture.
ShinyGS-a graphical toolkit with a serial of genetic and machine learning models for genomic selection: application, benchmarking, and recommendations.

Genomic prediction is a powerful approach for improving genetic gain and shortening the breeding cycles in animal and crop breeding programs. A series of statistical and machine learning models has been developed to increase the prediction performance continuously. However, the application of these models requires advanced R programming skills and command-line tools to perform quality control, format input files, and install packages and dependencies, posing challenges for breeders.

A microRNA with a non-canonical precursor structure harbours an intron in between its miRNA-5p and miRNA-3p relevant for its biogenesis, is conserved across Solanaceae, and targets the mRNA of low phosphate root. Hundreds of miRNAs have been identified in plants and great advances have been accomplished in the understanding of plant miRNA biogenesis, mechanisms and functions. Still, many miRNAs, particularly those with less conventional features, remain to be discovered.
