BACKGROUNDDeveloping new types of bioproducts using innovative nanotechnology is one of the potentially effective options for enhancing agricultural production and reducing environmental agrochemical pollution. As a bioagent derived from fungi, activator protein can promote growth and control diseases by activating the plant immune system. Meanwhile, the nanocarrier can protect the protein within and prolong its efficiency through controlled release. RESULTSIn our study, a new kind of plant nano-activator was developed by encapsulating an activator protein PeaT1 using a polymer nanoparticle constructed with monomethoxy-poly (ethylene glycol)-poly (lactide-co-glycolide) (mPEG-PLGA). The nanoparticles were spherical with diameter about 200nm. Morphological and physiological parameters of wheat seedlings, including seed vigor index, root vitality, chlorophyll content and photosynthetic parameters, increased after treatment with the nano-activator. Further observation under the confocal laser microscope showed a more effective intake of the nano-activator protein. CONCLUSIONThe results showed that the nano-activators are effective in enhancing wheat growth. This novel agent provides a promising way to improve crop production in an environmentally friendly manner. (c) 2018 Society of Chemical Industry
