Corn is a globally important crop; however, pest infestations during storage represent a major challenge. The maize weevil, Sitophilus zeamais (Coleoptera: Curculionidae), is a primary pest of stored maize, commonly controlled through phosphine fumigation. Nevertheless, extensive reliance on this insecticide has led to the emergence of resistant populations. Thus, the objective of this study was to evaluate the contact and fum...

Cutting black is an internal dark gray/black discoloration associated with pressure bruise in potatoes stored in piles, where sustained compression causes flattened areas and enzymatic browning. This defect leads to significant post-harvest losses, particularly affecting the fresh market. This 2-year study evaluated the effects of 1-methylcyclopropene, nitric oxide, and diphenylamine on cutting black development during simulat...

Ring chromosomes (RCs) are rare structural variants usually formed by fusion of both chromosome arm extremities, frequently associated with terminal deletions. RCs are investigated through karyotype, fluorescence in situ hybridization, chromosomal microarray analysis, and, more recently, optical genome mapping (OGM), which enables genome-wide structural variant detection; however, its accuracy depends on alignment to a referen...
