摘要：

The epidermal tissues of the cuticular membrane (CM) and periderm membrane (PM) confer first-line protection from environmental stresses in terrestrial plants. Although PM protection is essentially ubiquitous in plants, the protective mechanism, the function of many transcription factors and enzymes, and the genetic control of metabolic signaling pathways are poorly understood. Different microphenotypes and cellular components in russet (PM-covered) and green (CM-covered) fruit skins of pear were revealed by scanning and transmission electron microscopy. The two types of fruit skins showed distinct phytohormone accumulation, and different transcriptomic and proteomic profiles. The enriched pathways were detected by differentially expressed genes and proteins from the two omics analyses. A detailed analysis of the suberin biosynthesis pathways identified the regulatory signaling network, highlighting the general mechanisms required for periderm formation in russet fruit skin. The regulation of aquaporins at the protein level should play an important role in the specialized functions of russet fruit skin and PM-covered plant tissues.
