Track 4-1-4: Biotechnological Approaches to Improve Range, Pasture and Forage Species
Description
Grass-herbivore interaction is a complex process that involves wounding effects caused by herbivore feeding, defoliation effects due to leaf-surface loss during grazing, and the deposition of herbivore saliva onto the surface of plants (Chen et al., 2009). Wounding can stimulate plant growth but clearly differs from grazing (Mattiacci et al., 1995). Defoliation affects root development in grasses and alters the carbohydrate-metabolism pathway in rice. Saliva has been found to stimulate plant growth, enhance tiller and increase biomass. However, little is known about the molecular mechanisms of plant responses to grazing in molecular level. In our previous transcriptome studies, many genes relating with grazing were identified from sheepgrass (Li et al., 2013). In last IGC report, we proposed the concept of “molecular interface on grass-herbivore interaction” (Liu et al., 2013) to understand the interaction between plant and large herbivories on molecular level, which has significant importance on agriculture and grassland conservation. This paper will present some new results in the area.
