Distinct accumulation and remobilization of fructans in barley cultivars contrasting for photosynthetic performance and yield

Fructans are easily mobile storage carbohydrate in crops. In barley (Hordeum vulgare L.), a variable amount of fructans is stored in the stem or remobilized to the grain after flowering, which might be impacted by the photosynthetic performance. The aim of this work was to analyze the connection between photosynthetic performance, fructan content and activity of genes involved in the synthesis (1-SST, sucrose:sucrose-1-fructosyltransferase and...
