Abstract Changes in environmental conditions such as light intensity or temperature result
in an imbalance between the light energy absorbed through photochemistry versus the …

… the major polypeptides of the cytochrome b 6 f complex, transferring electrons from reduced
… -4S cluster (F X ). The PsaC polypeptide carries two redox active 4Fe-4S clusters (F A , F B ). …

Expression of the acidic dehydrin gene wcor410 was found to be associated with the
development of freezing tolerance in several Gramineae species. This gene is part of a family of …

The role of Ca2+ in cold-induced changes in protein phosphorylation, gene expression, and
development of freezing tolerance has been studied in cell-suspension cultures of a freezing…

The molecular genetics of vernalization, defined as the promotion of flowering by cold
treatment, is still poorly understood in cereals. To better understand this mechanism, we cloned …

… Houde, and F. Sarhan, unpublished results). Since the function of these cold-stimulated …
Susceptibility to photoinhibition was quantified by monitoring changes in F,/F, as a function …

… (e and f) Detailed view of a leaf trace and surrounding parenchyrna in a cold-acclimated …
(e and f) Detailed view of a vascular bundle from a cold-acclimated seedling. Enlarged region of …

Antifreeze proteins similar to two different chitinases accumulate during cold acclimation in
winter rye (Secale cereale). To determine whether these cold-responsive chitinases require …

… An example is the WCS19 gene from wheat, which is cold inducible but shows no CCGAC
element in its promoter region [225, Ouellet and Sarhan, unpublished results]. It is therefore …

Progress in freezing tolerance (FT) improvement through plant breeding approaches has
met with little success in the last 50 years. Engineering plants for greater FT through plant …
