Resumo(s)
Plants exhibit complex and integrated strategies to respond to stressful events involving particular signalling pathways, transcription factors and a number of specific stress-responsive genes. In addition, the regulation of genome accessibility is ensured by an efficient network of chromatin organization and epigenetic mechanisms which imply a heritable influence on gene activity that is not associated with changes in the DNA sequence. However, the functional role of these factors in plant response to stressful conditions is still largely unknown and so far direct connections between epigenome regulation and phenotypic plasticity are still poorly explained.(...)
