Abstract:
... Most plants can now be cryopreserved using one of several protocols, providing a stable, long-term and low-cost backup for clonally propagated plants. However, some plants respond poorly to cryopreservation due to lack of tolerance to low temperatures or osmotic and chemical stress. Low temperatures cause chilling and freezing injury and these sub-lethal changes can lead to increased production of ...

Abstract:
... Our previous studies showed that xylem parenchyma cells (XPCs) in trees, which adapt to winter cold by deep supercooling, contained several kinds of supercooling promoting substances [Kasuga et al., Cryobiology, 55 (2007) 305–314; Wang et al., Planta, 235 (2012) 747–759]. It is suggested that the presence of supercooling-promoting substances keeps liquid state of water in XPCs near −40°C. In the p ...
