Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
RNA silencing is an evolutionarily conserved mechanism in eukaryotes that control gene expression through small RNA-guided RNA degradation, translational repression and DNA methylation. Plants have evolved multiple small RNA pathways that have been demonstrated to play an essential role in developmental regulation and defence against invasive nucleic acids such as transposable elements and viruses. Recent studies have provided evidence that the different small RNA pathways play a more diverse role in plant defence against biotic and abiotic stresses. These findings are likely to result in new platforms for engineering stress tolerant crops in the future.
