Deadline for manuscript submissions: closed (31 March 2022) | Viewed by 25886. The inner bark is alive and acts as a base on which new layer is added every year, while the outer layer is composed of dead tissue. The epidermis is the outermost layer of cells on plant shoots. This process is responsible for healing in plants, from giant trees to a blade of grass. The suberized cork and non- suberized phelloid layers alternate each other. Submitted papers should be well formatted and use good English. The periderm is a cylindrical tissue that covers the surfaces of stems and roots of perennial plants during early secondary growth; therefore it is not found in monocots and is confined to those gymnosperms and eudicots that show secondary growth. Here, we summarize the data available on potato periderm formation, highlighting tissue characteristics rather than the suberization processes. These tissues are protected by the external periderm situated on the peripheral side and inner or interxylary periderm present on the inner side.
