The use of liquid nitrogen (LN) in plant gene banks is currently limited, with only 20 out of 500 banks in Europe utilizing cryogenic temperatures. Poland has gradually developed its gene banking system since the 1990s, mainly focusing on seed collection. This review provides the first summary of gene cryobank activities and resources in Poland, highlighting the use of LN in plant protection programs and presenting the characteristics of four existing gene cryobanks in the country.
To date, the use of liquid nitrogen (LN) in plant gene banks is relatively limited. Globally, in 2021, approximately 10,000 accessions were cryopreserved, and their explants were derived from in vitro plants. In Europe, out of 500 banks, only 20 use cryogenic temperatures to store plant germplasms. The implementation of seven conservation projects in Poland starting in the 1990s meant that the gene banking system in this country began to gradually develop. Plant gene bank is mainly based on the collection of seeds and makes little use of plant tissues, including those from in vitro culture. From the point of view of systematics, plant material belonging to spermatophytes dominates in Polish gene banks, while spore plants are rarely represented. This review represents the first summary of gene cryobank activities and resources in Poland. It contains a brief overview of the ex situ plant protection programs aimed at the use of LN and presents the characteristics of four existing gene cryobanks in this country. Special attention is devoted to the presentation of studies on the cryopreservation of seeds, as well as of plant tissues, such as embryonic axes and plumules of trees, and fern gametophytes, that make a permanent contribution to gene bank resources.
