About the Cover
On the Cover: Germination of pea seeds on ice. Dry pea seeds were placed on ice in a covered polystyrene box that was stored at 1.5
C. Ice was changed weekly and the photograph was taken after 6 weeks. When transferred to soil, the ice-germinated seeds developed into healthy pea plants. Such a performance is likely to be related to the amazing temperature tolerance of seed mitochondria that are able to sustain oxidative phosphorylation at subfreezing temperatures, using exogenous NADH as a substrate (Stupnikova et al., pp. 326-335).
