Gallium (Ga), indium (In) and thallium (Tl) are considered the emerging contamination elements (ECEs) because of the development of the high-tech industries such as electronics industry and semiconductor industry. The potential risk of Ga, In and Tl are nonessential heavy metal that will pose environmental and biological threats. Four days later after treatment, the shoot length of control and thallium treatment are 13.4 cm and 7.2 cm respectively; the root length of control and gallium treatment are 6.7 cm and 8.3 cm respectively. The results show that there has inhibition to shoot length of rice in thallium treatment but has promotion to root length of rice in gallium treatment. Hence we supposed that may have an relation between ECEs absorption and auxin distribution. The GUS staining result shows that there has no difference on GUS staining distribution between Ga treatment and control, however, there nearly has no GUS staining on rice root of thallium treatment but on the tip of lateral root.
