Integrative "omic" analysis reveals distinctive cold responses in leaves and roots of strawberry, Fragaria × ananassa 'Korona'.

To assess underlying metabolic processes and regulatory mechanisms during cold exposure of strawberry, integrative "omic" approaches were applied to Fragaria × ananassa Duch. 'Korona.' Both root and leaf tissues were examined for responses to the cold acclimation processes.

Metabolite profiling reveals novel multi-level cold responses in the diploid model Fragaria vesca (woodland strawberry).

Winter freezing damage is a crucial factor in overwintering crops such as the octoploid strawberry (Fragaria × ananassa Duch.) when grown in a perennial cultivation system. Our study aimed at assessing metabolic processes and regulatory mechanisms in the close-related diploid model woodland strawberry (Fragaria vescaL.

Ion binding properties of the dehydrin ERD14 are dependent upon phosphorylation.

The ERD14 protein (early response to dehydration) is a member of the dehydrin family of proteins which accumulate in response to dehydration-related environmental stresses. Here we show the Arabidopsis dehydrin, ERD14, possesses ion binding properties. ERD14 is an in vitro substrate of casein kinase II; the phosphorylation resulting both in a shift in apparent molecular mass on SDS-PAGE gels and increased calcium binding activity.

The calcium-binding activity of a vacuole-associated, dehydrin-like protein is regulated by phosphorylation.

A vacuole membrane-associated calcium-binding protein with an apparent mass of 45 kD was purified from celery (Apium graveolens). This protein, VCaB45, is enriched in highly vacuolate tissues and is located within the lumen of vacuoles. Antigenically related proteins are present in many dicotyledonous plants.
