Tanaman memiliki adaptasi yang berbeda untuk melindungi diri dari cedera kulit. Berat umbi yang berkurang karena kehilangan air dikaitkan dengan tingkat pembusukan yang lebih tinggi, terutama terjadi di negara-negara berkembang dan yang kurang berkembang dengan kehilangan hasil panen umbi 8-20%. Cedera kulit ini bertanggung jawab atas kerugian pascapanen yang signifikan akibat peningkatan laju kelembaban dan penurunan berat umbi, pengerutan, dan kerentanan terhadap serangan patogen. Lamb), cedera kulit adalah hilangnya kulit dari permukaan umbi. Keywords : gene expression, Ipomoea batatas, lignification, postharvest loss, wounding This paper especially reviews and discusses skinning injury responses in sweetpotato, a root crop which product may severely be affected by skinning injury.

Understanding the skinning injury responses and how to regulate them can be used to produce a more desirable plant resistant to skinning injury. Genes associated in the biosynthesis of lignin and suberin, protein fate, cell-wall modification, transcription and protein synthesis, and stress responses and defense have been associated with skinning injury responses in plants.
Changing in gene expressions have been associated with skinning injury. Lignification, suberization, and increased sugar at the wound site have been shown to be correlated with wound healing. Plants have different adaptation to protect themselves against skinning injury. Reduced root weight by water loss is associated with a higher rate of rot predominantly occurred in the developing and underdeveloped countries which can count of 8-20% of postharvest loss. It is responsible for significant postharvest loss resulting from moisture increase and weight reduction, wrinkling, and susceptibility to pathogen attack. Lamb), the loss of skin from the surface of the storage roots is known as skinning injury.
