The environmental conditions are formed by multiple factors, and the resulting effects on plants are not easy to predict. However, the environment determines the vitality and yield of the crops, as well as the quality and nutrimental content of the produced seeds. To study the effects of the environment on the seed and its proteome and metabolome quality, we analyzed barley caryopses of three barley cultivars collected from 12 different locations all over the Czech Republic. Based on the protein quantification and locality-specific data we collected (e.g. recorded temperatures and rainfalls), samples of four contrasting environments were selected for detailed analysis. Our results confirm a significant impact of the environment on the seed quality, which was higher than cross-cultivar variations. This study contributes to our knowledge about plant response to combined biotic and abiotic stimuli, typical for field conditions, and provides candidates that may be useful for a targeted gene manipulation or as selection markers in breeding more resistant crops.
