Název v původním jazyce

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

Popis výsledku v původním jazyce

A dynamics of plant development, frost tolerance (FT) and DHN5 accumulation in a frost-susceptible spring barley Atlas 68, a moderately tolerant winter barley Igri and a set of selected doubled-haploid lines derived from Atlas 68 x Igri cross was studiedunder a long-term cold acclimation (CA; 112 days at 3 °C). At the beginning of the treatment, FT and DHN5 levels rose in all barley genotypes; however, they started decreasing in the spring genotypes after about 21 days of CA when they approached a moresusceptible reproductive stage indicated by a formation of double-ridge structure in shoot apex. In winter genotypes, both FT and DHN5 rose until vernalization; after vernalization, DHN5 started decreasing while FT remained high under a continuous CA treatment indicating a discrepancy between the dynamics of FT and DHN5 in vernalized plants. A relationship between DHN5 accumulation and plant winter survival is also discussed suggesting a possible use of DHN5 as a marker of plant winter
