This summer will be my 4th year growing corn for my research. Every year, I’ve seen some crazy things in the transgenic and non-transgenic fields alike. For example:

On the left is “tassel ear”, where silks and kernels (female, seed producing plant parts) appear on the tassel (male, pollen producing plant parts), where they are most certainly NOT supposed to be – it’s ok for sorghum and other grasses, but not for corn! On the right, there are at least 2 ears where there should be one, and those leaves poking out between the two might be more ears. Neither of these plants are transgenic or carry heritable mutations that cause these strange phenotypes. Both transgenic and non-transgenic fields are treated with a herbicide before we plant but after that the plants are grown with no additives, chemical or otherwise.

So, what the heck is going on?
