These viruses offer the potential to cure cancer, correct genetic disorders, or fight pathogenic viral infections. Conversely, ammonia which gives of alkaline vapor may have the opposite effect.". Viruses are non-cellular, microscopic infectious agents that can only replicate inside a host cell. The main factors driving virus emergence are: i) the agricultural systems based on monocrops with low genetic diversity and high plant density, which are more vulnerable to pathogens and pests; ii) world trade of plant material (germplasm and live plants) that moves viruses, hosts, and vectors to new regions and environments; iii) the climate ch.
