Summary:

Once a plant has germinated in a particular location, it cannot change it anymore. This means its growth depends on its location with its particular context, such as soil, herbivores, or sunlight levels. Therefore plants have evolved sophisticated signal transduction systems that allow them to perceive the outside world and then modify their growth, morphology and chemicals production and develop different phenotypes. IAN BALDWIN and his research team investigate how exactly this process happens. As Baldwin describes in this video, the recently published genome of Nicotiana attenuata allows the researchers to examine the possibility that not only protein-coding genes but also non-coding RNA is involved in the regulatory process in the genome. Using RNAi to silence protein-coding genes, they take these engineered plants into the field and observe the differences. Their findings confirm the hypothesis that the small RNA machinery causes the change in phenotype.
