主　　题：Arsenic Pseudomonas putida Arsenate reduction Endophyte Wolffia globosa Phytoremediation 

摘      要：Arsenic is a ubiquitous environmental ***-mediated arsenic biotransformations significantly infuence arsenic mobility and *** transformations by soil and aquatic organisms have been well documented,while little is known regarding effects due to endophytic *** endophyte Pseudomonas putida ARS1 was isolated from rice grown in arsenic contaminated *** ARS1 shows high tolerance to arsenite(As(Ⅲ))and arsenate(As(V)),and exhibits efficient As(V)reduction and As(Ⅲ)effux *** exposed to 0.6 mg/L As(V),As(V)in the medium was completely converted to As(Ⅲ)by *** ARS1 within 4 *** sequencing showed that *** ARS1 has two chromosomal arsenic resistance gene clusters(arsRCBH)that contribute to efficient As(V)reduction and As(Ⅲ)effux,and result in high resistance to *** globosa is a strong arsenic accumulator with high potential for arsenic phytoremediation,which takes up As(Ⅲ)more efficiently than As(V).Co-culture of *** ARS1 and *** enhanced arsenic accumulation in *** by 69%,and resulted in 91%removal of arsenic(at initial concentration of 0.6 mg/L As(V))from water within 3 *** study provides a promising strategy for in situ arsenic phytoremediation through the cooperation of plant and endophytic bacterium.
