Gene expression of coffee seed oxidation and germination processes during drying

G. C. Santos, Von Pinho, E. V. R., and Rosa, S. D. V. F., Gene expression of coffee seed oxidation and germination processes during drying, vol. 12, pp. 6968-6982, 2013.

Coffee (Coffea arabica L.) seeds are sensitive to desiccation and oxidative stress during drying processes. We investigated the effect of drying and moisture levels on germination-related gene expressions associated with enzymatic systems that prevent oxidative stress in coffee seeds. Coffee seeds collected at physiological maturity were subjected to slow and quick drying to 40, 30, 20, and 12% moisture levels (wet basis), and as the control, seeds without drying were used.

Mapping of quantitative trait locus associated with maize tolerance to high seed drying temperature

Quantitative trait locus (QTL) mapping and identification of traits of agronomic importance is important in the process of molecular marker-assisted selection in breeding programs. The molecular map of maize is well saturated and QTL and simple sequence repeat (SSR) markers have been identified, whereas few markers linked to seed quality traits are included. The present study aimed to identify QTL and the gene action and to quantify the effects of these regions in the phenotypic variation related to maize tolerance to high seed drying temperature.
