A cDNA clone encoding a protein (CuCOR19), the sequence of which is similar
to Poncirus COR19, of the dehydrin family was isolated from the epicarp of
Citrus unshiu. The molecular mass of the predicted protein was 18,980 dalt
ons. CuCOR19 was highly hydrophilic and contained three repeating elements
including Lys-rich motifs. The gene expression in leaves increased by cold
stress.
