영문 초록

Heavy metals are limiting factor of growth and production yield in plants. Heavy metal stress causes accumulation of reactive oxygen species (ROS) and disturb ion homeostasis. Plants have developed to efflux excess heavy metals and sequsterate mechanism. For example, vacuole localized P-type ATPase, heavy metal ATPase 3 (HMA3) can sequesterate heavy metals (Zn, Pb, Cd and Co) into vacuole. Biopolymers were produced by living organism. In previous study, biopolymers were reported that enhanced soil strength and water retention capacity. But, effect on heavy metal by amended soil with biopolymer was not tested in Camelina yet. In this study, we investigated Camelina growth, metal contents and accumulation of HMA3 protein under heavy metal stress when soil was amended with or without biopolymers.
