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

The development of frost tolerance and DHN5 protein accumulation in barley (Hordeum vulgare) doubled haploid lines derived from Atlas 68×Igri cross during cold acclimation

“…Therefore, the accumulation of DHN5 protein can be used for estimation of the acquired FT level in barley. This situation is analogous to that in common wheat (Triticum aestivum), where the cold-inducible dehydrin wheat cold-specific 120 gene (WCS120) has been proposed as a marker of FT (Houde et al, 1992;Vítá mvá s et al, 2007).…”

Wheat and barley dehydrins under cold, drought, and salinity – what can LEA-II proteins tell us about plant stress response?

“…At dehydrin sequence level, there has been found a relationship between allelic variation in Dhn4 and Dhn7 gene sequence (a 6 bp insertion in exon 1 of Dhn4 and a 30 bp deletion in exon 1 of Dhn7 ) and acquired frost tolerance in a set of 30 barley cultivars including both spring and winter growth habits of a wide range of lethal temperature of 50% of the sample (LT50) values (Holková et al, 2010). At transcript and protein levels, there has been repeatedly reported a correlation between dehydrin accumulation and plant acquired frost tolerance in short-term (7 to 21 days) cold acclimation studies (Houde et al, 1992; Vítámvás et al, 2007; Kosová et al, 2008b; Holková et al, 2009). There have been found significant and reproducible differences not only between the contrasting growth habits (spring vs winter), but also at a scale of differentially frost-tolerant winter genotypes when plants were grown under controlled conditions (constant cold temperature and irradiation, neutral photoperiod 12 h day/night).…”

Expression of dehydrin 5 during the development of frost tolerance in barley (Hordeum vulgare)

“…Thus, the WCS120 protein is considered a marker of FT in wheat (Houde et al, 1992). Recently, Vítámvás et al (2007) distinguished two differentially frost-tolerant winter wheat cultivars -Mironovskaya 808 and Bezostaya -on the basis of different amounts of accumulated WCS120 proteins after 3 weeks of cold acclimation (CA).…”
