The frequently changing climate has resulted in plants facing more biotic and abiotic stresses than ever before, leading to yield and quality losses. The global population is increasing at an alarming rate and feeding the world has become a huge challenge. Being a staple crop of many countries, potato can help to overcome this challenge. A comprehensive knowledge of physiology, biochemistry and molecular genetics of development and wound healing of potato tuber periderm (skin) is very important as the periderm protects the tubers from skinning injuries, dehydration, bruising and biotic and abiotic stresses. Improvements in tuber periderm are essential to enhance tuber quality and shelf life and reduce financial losses. In this paper, we have reviewed the protective roles of tuber periderm layer in response to stress and injuries. Moreover, molecular regulation of native and wound-induced periderm formation has been discussed. Since suberization is an important aspect of tuber periderm formation and wound healing, we have also reviewed the key genes involved in this process. This review will pave the way for obtaining potato tubers resistant to various abiotic and pathogenic stresses.

气候变化频繁导致植物面临比以往更多的生物和非生物胁迫，导致产量和质量下降。全球人口正以惊人的速度增长，养活世界已成为一个巨大的挑战。作为许多国家的主粮，马铃薯可以帮助克服这一挑战。马铃薯块茎皮（皮肤）的发育和伤口愈合的生理学，生物化学和分子遗传学方面的全面知识非常重要，因为该皮周组织可以保护块茎免受皮肤伤害，脱水，青紫以及生物和非生物胁迫。改善块茎皮对提高块茎质量和货架寿命并减少经济损失至关重要。在本文中，我们综述了块茎皮层对压力和伤害的保护作用。此外，已经讨论了天然和伤口诱导的皮层形成的分子调控。由于消沉作用是块茎周皮形成和伤口愈合的重要方面，因此我们也综述了该过程涉及的关键基因。这项审查将为获得对各种非生物和致病性胁迫具有抗性的马铃薯块茎铺平道路。
