Plant cryopreservation: a continuing requirement for food and ecosystem security

Abstract

This issue of In Vitro Cellular and Developmental Biology—Plant is dedicated to current developments in liquid-nitrogen cryopreservation methods and their use in plant biology and germplasm preservation. The development of cryopreservation for storage of plant cells, tissues, and organs began in the 1960s and continues to this day. Long-term storage of in vitro cultures of secondary metabolite cell cultures, embryogenic cultures, clonal germplasm, endangered species, and transgenic products remains an important requirement for many scientists, organizations, and companies. The continued development of cryopreservation techniques and their application to new plants is the subject of this issue.
