Barley (Hordeum vulgare L.) is an important cereal crop, but its sustainable production significantly hampered due to the presence of various edaphic stresses. Understanding variability in root morphological traits among diverse barley genotypes critical for selecting those with suitable breeding new cultivars better adapted stress environments. Root early growth stage (30 days after transplant...

Turnover of ribulose 1,5-diphosphate carboxylase in barley leaves (Hordeum vulgare L.) was followed over time in light and dark. The enzyme was degraded in prolonged darkness and was resynthesized after the plants were returned to light. Labeling with (14)C showed that simultaneous synthesis and degradation (turnover) did not occur in light. In contrast, the remaining soluble protein was turned...
