Identification and characterization of a low temperature regulated gene encoding an actin‐binding protein from wheat

Identification of genes associated with cold acclimation in perennial ryegrass

“…Many COR and LEA proteins function as membrane stabilizers and thus enhance cold tolerance in plants (Thomashow, 1999). Wheat cold-acclimation protein WSC19 (WSC19) and WCOR719 proteins may function as cold-responsive transcription factors to induce the expression of downstream genes that are related to cold tolerance (Chauvin et al, 1993;Danyluk et al, 1996). Two IRI protein genes were identified as being up-regulated after cold acclimation.…”

WCS120 protein family and proteins soluble upon boiling in cold-acclimated winter wheat

“…WCS19 and COR14a (WCOR14) belong to three LEA chloroplastic proteins and their accumulation is stimulated by light and cold temperature (Chauvin et al, 1993;NDong et al, 2002). WCOR719 is an actin-binding protein (Danyluk et al, 1996). Cold-responsive LEA/RAB-related COR protein is responsive to the abscisic acid pathway (Tsuda et al, 2000).…”

A cold-responsive wheat (Triticum aestivum L.) gene wcor14 identified in a winter-hardy cultivar 'Mironovska 808'.

“…A gene wcs120 and its related, perhaps paralogous genes including Wcor39, Wcs66, Wcor80, Wcor200 and Wcor726 are expressed in response to low temperature (Houde et al, 1992;Guo et al, 1992;Quellet et al, 1993;Chauvin et al, 1994;Danyluk et al, 1996;Hughes and Dunn, 1996). Among them, wcs120 and wcor200 are the most well characterized members respectively encoding glycine-rich neutral proteins of 50 kDa (pI = 7.3) and 200 kDa (pI = 6.5) with characteristics of the group 2 LEA (or D-11) family, although they do not have a conserved polyserine sequence (Houde et al, 1992;Quellet et al, 1993).…”
