The purpose of this work was to morphologically characterize an apple tree collection composed 67 individuals from 41 accessions belonging 23 old Spanish cultivars (Malus domestica Borkh) alongside 9 reference cultivars. studied germplasm collected previously in rural areas central Spain (Sierra Norte de Madrid and Tagus river basin) it analyzed through descriptors mainly IBPGR UPOV. We found a...

The article describes changes in the structure, leaves, (including mesophyll structure of midrib, distribution stomata, and number vascular bundles) Malus during growing season (from June to August) under influence prolonged drought. leaves anatomy morphology were investigated by methods light scanning electron microscopy. study was carried out on four representatives genus Malus: M. niedzwetzk...

BACKGROUND Domesticated apple (Malus × domestica Borkh) is a popular temperate fruit with high nutrient levels and diverse flavors. In 2012, global apple production accounted for at least one tenth of all harvested fruits. A high-quality apple genome assembly is crucial for the selection and breeding of new cultivars. Currently, a single reference genome is available for apple, assembled from 1...

miRNAs are important regulators involving in plant-pathogen interactions. However, their roles in apple tree response to Valsa canker pathogen (Valsa mali, Vm) infection were poorly understood. In this study, we constructed two miRNA libraries using the twig bark tissues of apple tree (Malus domestica Borkh. cv. "Fuji") inoculated with Vm (IVm) and PDA medium (control, BMd). Among all detected ...
