Periderm (cork) tissue development


Potato tuber periderm - studies on the development of corky tissue and related potato skin disorders in the field

The skin of potato tuber is made of periderm tissue. The periderm replaces the original epidermal cell layer of the tuber early in development, and is made up of three cell types. The phellem that composes the tuber skin, the meristematic phellogen that creates the skin, and parenchyma-like phelloderm. The protective characteristics of the periderm are thought to derive from the deposition of suberin on the walls of its phellem resulting with corky skin. The periderm is also enriched with enzymes and metabolites involved in the plant's responses to biotic and abiotic stresses that further add to its protective role. Impairment of periderm development affects its protective characteristics against water loss and pathogen invasion, and reduces tuber storage quality and tuber visual appearance and marketability.

Periderm plays a crucial role in agricultural crops. It constitutes the skin of sweet potato and carrot as well, and the netted rind of melons - all are desired traits - but is also the cause of substantial costly damages such as russeting problems in potato, apple, pear, tomato, etc. In potato it also involved with skinning injuries during harvest and with secondary metabolism of anthocyanins and glycoalkaloids, both are mainly accumulated in the parenchyma-like phelloderm.

We conduct basic and applied science to characterize the function of the potato periderm. That knowledge is being translated for the elevation of nutritional values and marketability of fruits and vegetables.
