Abstract: The large scale use of antibiotics in medicine, animal husbandry, and aquaculture induces the increasing emergence of antibiotic resistance bacteria and antibiotic resistance genes (ARGs), and, as a kind of new environmental contaminants, the ARGs are attracted much attention by the public. This paper summarized the research progress of ARGs in recent years, and discussed the transport of ARGs in water, soil, and air, and in plants and animals. The necessity of the study on ARGs in environment and the existing problems in present studies were pointed out, and the research methods of antibiotic resistance (including antibiotic resistance bacteria and ARGs) were introduced. Some related research directions were proposed.

Key words: antibiotics, antibiotic resistance, antibiotic resistance bacteria, antibiotic resistance gene, rape (Brassica napus), selenite, absorption, distribution, root morphology, physiological characteristics.
