Dataset Information


Transcription profiling by array of tobacco infected with tobacco mosaic virus or expressing the whole tobacco mosaic virus genome.

ABSTRACT: Agilent 4x44k tobacco micro array of wild type tobacco (WT) and whole tobacco mosaic virus (TMV) containing transgenic tobacco plants. The transgenic plants before resistance break (BRB-6 weeks), after resistance break (ARB-8 weeks) and wild type tobacco plants infected with TMV (TMVi-9weeks) leaves were analyzed. Three biological replicates were performed for each sample.

Previously described transgenic tobacco lines express the full length infectious Tobacco mosaic virus (TMV) genome under the 35S promoter (Siddiqui et al., 2007. Mol Plant Microbe Interact, 20: 1489-1494). Through their young stages these plants exhibit strong resistance against both the endogenously expressed and exogenously inoculated TMV, but at the age of about 7-8 weeks they break into TMV infection, with typical severe virus symptoms. Infections with some other viruses (Potato viruses Y, A  ...[more]
