چکیده انگلیسی
Cystatins or phytocystatins (PhyCys) comprise a family of plant-specific inhibitors of cysteine proteinases. Such inhibitors are thought to be involved in the regulation of several endogenous processes as well as defense against biotic or abiotic stresses. However, information about this family is limited in apple. We identified 26 PhyCys genes within the entire apple genome. They were clustered into three distinct groups distributed across several chromosomes. All of their putative proteins contained one or two typical cystatin domains, which shared the characteristic motifs of PhyCys. Eight selected genes displayed differential expression patterns in various tissues. Moreover, their transcript levels were also up-regulated significantly in leaves during maturation, senescence or in response to treatment with one or more abiotic stresses. Our results indicated that members of this family may function in tissue development, leaf senescence, and adaptation to adverse environments in apple.
