Ion Beam Bio-Engineering and Crop Breeding

Abstract

Ion beam bio-engineering was established by Chinese researcher in 1980s. Over thirty years past, there were delightful progress by low energy ion beam induced mutants and crop improvement. When ion beam implant the organism, charge exchanged between ions and organism surfaces. Meanwhile there were ion sputtering, ion penetration and surface damage of plant cell wall material. Owing to etching action of low energy beam to plant cell wall, ion beam mediated exogenous DNA transformation becomes possible. Representative applications and achievements in crop breeding were described.

Introduction to Plant Mutation Breeding: Different Approaches and Mutagenic Agents

“…Over the past 30 years, Ion beam irradiation and ion beam implantation have gained popularity (Wang et al, 2010). Ion beams are capable of depositing high energy on a target, densely and locally.…”

“…Ion beams are capable of depositing high energy on a target, densely and locally. As a result, a higher mutation rate and wider novel mutation spectrum can be observed in mutants subjected to ion beam irradiation (Yamaguchi et al, 2009;Wang et al, 2010).…”
