Abstract
Genetic tumors can develop on certain tobacco hybrid plant spontaneously In this study exogenous hormones were applied on the tumorous tobacco hybrid seedlings N glauca × N langsdorffii and the data showed that N6benzyladenine BA enhanced the tumor formation under both tissue culture and field conditions and NAA and ABA inhibited tumor formation under tissue culture condition whereas ABA accelerated the tumor formation under field condition Furthermore Northern analysis indicated that tumor tissue exhibited high level of CycD expression compared with normal tissues implying abnormal cell cycle of tumor cells The differential display reverse transcription PCR DDRT PCR results indicated some genes may be involved in tumor formation
