The study investigated whether cucumber mosaic virus (CMV) can be transmitted by direct plant-to-plant contact. Infected pepper plants were rubbed against healthy plants and then placed in contact for 28 days, with subsequent DAS-ELISA testing revealing successful transmission to several weed species but not to Trifolium repens. These results emphasize the need to consider contact transmission when designing experiments and implementing biosecurity measures.

The study uses a multi‑omics strategy to chart transcriptomic and epigenomic changes throughout pepper (Capsicum) fruit pericarp development and ripening, linking chromatin accessibility, H3K27ac/H3K27me3 dynamics, and global DNA demethylation to transcriptional reprogramming. Network analysis suggests that ripening regulators known from climacteric tomato also function in non‑climacteric pepper, and epigenetic regulation of carotenoid and vitamin C biosynthesis pathways is detailed.

The study evaluated morphological, physiological, and yield traits of eight sweet pepper (Capsicum annuum) hybrids compared to two check varieties, assessing standard heterosis and identifying superior hybrids. Field and lab experiments using RCBD and CRD designs with three replications revealed significant trait variation, and statistical analyses (Pearson correlation and PCA) highlighted key associations for breeding.
