Phenotypic changes and DNA methylation status in cryopreserved seeds of rye (Secale cereale L.)
Conserving genetic diversity is one of the major tasks for seed banks worldwide. At present, there are two long-term preservation methods in the USDA-ARS National Laboratory of Genetic Resources Preservation (NLGRP)：storage in a -18 °C vault (conventional storage) and storage in a liquid nitrogen vapor phase ranging from -135 oC to -180 °C (cryopreservation). Cryopreservation is considered to be the best method for long-term storage of vegetatively propagated plants and sometimes can be effective for recalcitrant seeds, but its value for orthodox seeds has not been thoroughly tested. Rye (Secale ...
