| Notes | AC2 gene of Tomato yellow leaf curl Guangdong virus isolate G3 （ TYLCGuV- [ G3 ] ） was amplified from its recombinant plasmid by PCR, and the gene was cloned into prokaryote expression vector pET-28b（ ＋ ）. The expressed fusion protein was highly expressed in Escherichia coli Rosetta（ DE3 ）Ⅲ induced by IPTG, and the molecular mass was about 19 500 by SDS-PAGE analysis. The fusion protein was used as an antigen to immunize the healthy rabbit and the antiserum of AC2 was prepared. The titer measured by ELISA was about 1：16 384. Western-blotting analysis indicated that the antiserum could serologically react with AC2 protein of TYLCGuV-[ G3 ]. 44-1110/S Tomato yellow leaf curl Guangdong virus; AC2 gene ; prokaryotic expression; antiserumpreparation ZHAO Qin, LI Hua-ping , HE Zi-fu, SHE Xiao-man , XIE Da-sen , HE Xiao-ming , PENG Qing-wu （ 1 Vegetable Research Institute, Gnangdong Academy of Agricultural Sciences, Guangzhou 510640, China; 2 Laboratory of Plant Virology, South China Agricultural University, Guangzhou |
