The transcription of the tobacco Tnt1 retrotransposon was previously shown to be induced, in tobacco and in heterologous species, by microbial elicitors and by pathogen infections. We report here that the expression of the Tnt1 promoter is also activated in heterologous species such as tomato and Arabidopsis by wounding, freezing and by other abiotic factors known to induce the plant defence response, such as salicylic acid, CuCl2, or oxidative stress. A similar regulation is observed in… CONTINUE READING
