Non-GMO seed companies include such organic companies as Baker Creek, Peaceful Valley and Seeds Now. Many such companies sign the "Safe Seeds Pledge" that they will not knowingly sell seeds that contain genetically modified organisms.
A non-GMO is an organism that has not been altered in a lab with a gene from an unrelated organism, such as corn that has been altered with a gene from a bacteria.
There are no certificates that certify a product is totally free of GMOs, not even the Non-GMO Project or organic certifications.
There is nothing inherently bad about GMO but there are many people who have serious questions about them. The main issue is that they are so new that if there are long-term problems from them we would not know about them yet. Since they are regulated as foods, they typically are not tested like drugs for safety. An ancillary problem is that nearly all GMO are produced under patent so poor farmers cannot afford to buy them. Also, unlike non-GMO, farmers are not allowed to set aside seed from their harvest to use in future plantings. They are required to buy completely new seed from the patent holder for each planting.
If you are a farmer, you know the corn you are gowing is GMO because you buy seeds that are known to be GMO. If you are gowing non-GMO varieties, you do not know if GMO vaieties have cross pollinated with your corn unless you get it tested. If you are a consumer, you do not know if the corn or processed foods containing corn is GMO unless it is labeled as such. In the United States GMO foods are not labeled.
[1] Non-genetically modified organism products can easily be contaminated by air and by seed. The gmo contamination can show up in areas that aren't using gmo. And it has shown up in uncultivated areas; and in cultivated areas such as backyard gardens, and conventional and organic farms. [2] Despite the previous statements, that it's genetically modified organism free is what's being said thus far about Sunrise products.
This website offers a long list of seed growers like the ones you describe: http://www.crudeawakening.org/seeds.htm

Eggplant may or may not be organically grown. If it is grown from a non-GMO seed and no synthetic pesticides are used, it is organically grown.
GMO foods asummably have the same vitamins as the equivalent non-GMO foods.
GMO corn and soy are no more productive than non-GMO corn and soy.
There are no certificates that certify a product is totally free of GMOs, not even the Non-GMO Project or organic certifications.
I work for a company here in the United States that grows and sells purple corn. All of our corn is non-gmo organic or non-gmo non organic.
In the United States, genetically modified foods have been declared to be "substantially equivalent" to non-GMO foods, so there are no differences in how they are grown. There are recommendations for GMO farmers to plant barriers of non-GMO crops to cut down on cross pollination of their crops with non-GMO crops, but these are just recommendations and are not enforced.

GMO foods last about the same amount of time as non-GMo foods.
