 Therefore, it was hypothesized that any offspring produced by from these two lines of tobacco plant should not be able to grow on spectinomycin or be fluorescent, as the genetic material in the chloroplast should not be able to transfer via pollen.However, it was found that some of the seeds were resistant to the antibiotic and could germinate on spectinomycin agar plates.Calculations showed that 1 out of every million pollen grains contained plastid genetic material, which would be significant in an agricultural farm setting.
