Abstract: Tobacco (Nicotiana tabacum L.) "NC89" plants were transformed with deletion mutant of cucumber mosaic virus (CMV) movement protein (MP) gene and full-length CMV MP gene, respectively. The transformed plants were analyzed with polymerase chain reaction (PCR), PCR-Southern, Southern and Western blots. R0 generation of the transgenic plants were inoculated with CMV. Five out of 10 lines of tobacco plants (BMPK) transformed with CMV MP deletion mutant gene showed high resistance to CMV infection and remained symptomless for up to 50 days post-inoculation. In contrast, tobacco plants (BMPR) transformed with full-length CMV MP gene did not show resistance to CMV infection. However, most of the infected full-length CMV MP gene transgenic plants recovered by showing none or very mild mosaic symptoms in 40 days post-inoculation. The results of R1 generation of the BMPK transgenic plants tested under field conditions showed that all 5 lines of transgenic plants could delay the virus disease development.
