During 2017, leaf samples of chili pepper (Capsicum annuum), tomato (Solanum lycopersicum), and tobacco (Nicotiana tabacum) plants exhibiting yellowing and curling symptoms were collected from Aceh province, Indonesia. These samples were used to isolate and sequence viral genomic DNA. Six isolates with complete DNA-A and DNA-B sequences of begomovirus were obtained, all of which showed >99% sequence identity to the others. DNA-A sequences shared the highest nucleotide sequence identity (89.3%-89.7%) with monopartite pepper yellow leaf curl Indonesia virus 2 (PepYLCIV2) and the second-highest sequence identity (87.3%-87.4%) with bipartite pepper yellow leaf curl Indonesia virus (PepYLCIV). The DNA-B sequences shared the highest nucleotide sequence identity (95%-97.5%) with PepYLCIV. Results of recombination analysis indicated that the novel begomovirus was a recombinant. In accordance with the guidelines for begomovirus species demarcation, these isolates should be assigned to a new species, and we have proposed the name ''pepper yellow leaf curl Aceh virus'' (PepYLCAV) for this virus.

The wilting and yellowing of leafy vegetables caused by spoilage bacteria resulted in serious resource wastage. This study investigated the efficacy of a combined lactic acid (LA) and tartaric acid (TA) treatment against four predominant spoilage bacteria (Erwinia persicina, Citrobacter freundii, Pseudomonas putida, and Pseudomonas punonensis) isolated from spinach and oilseed rape. Detailed analysis using Fourier-transform infrared spectroscopy, flow cytometry, scanning electron microscopy, and light microscopy revealed substantial cellular damage in the bacteria treated by LA and TA, including loss of intracellular material, and collapse of cellular morphology, as well as effective biofilm removal.

Common ash (Fraxinus excelsior) is under intensive attack from the invasive alien pathogenic fungus Hymenoscyphus fraxineus, causing ash dieback at epidemic levels throughout Europe. Previous studies have found significant genetic variation among genotypes in ash dieback susceptibility and that host phenology, such as autumn yellowing, is correlated with susceptibility of ash trees to H. fraxineus; however, the genomic basis of ash dieback tolerance in F.

Gloriosa L. possesses exceptional ornamental value, with its floral hues exhibiting a wide range of variations. In this study, we employed sophisticated colorimetry, Ultra Performance Liquid Chromatography-Tandem Mass Spectrometry (UPLC-MS/MS), and transcriptome sequencing to investigate the phenotypic expression of tepal colors, the composition of carotenoids and anthocyanins, and the differential gene expression in four Gloriosa varieties during their full bloom phase.

Understanding and predicting plant water dynamics during and after water stress is increasingly important but challenging because the high-dimensional nature of the soil-plant-atmosphere system makes it difficult to identify mechanisms and constrain behaviour. Datasets that capture hydrological, physiological and meteorological variation during changing water availability are relatively rare but offer a potentially valuable resource to constrain plant water dynamics. This study reports on a drydown and re-wetting experiment of potted Populus trichocarpa, which intensively characterised plant water fluxes, water status and water sources.
