Thank you very much for your input to this important subject. There is often
too much Chicken Little mentality involved due to ignorance thus aiding the
fear of all gene transplanting. Hope I'm not stepping on too many toes.
Too bad more people will not read your excellent explanation. Unless I hear
differently from you I'll submit it for publication in Pomona, The Hoosier
Kernel (Indiana Nut Growers news letter) and The Nut Shell (Northern Nut Growers
The monetary aims of agribusiness is often questioned (and such questioning
is healthy when done with an open mind), but every time I see a scare article
come out, I can't help but be reminded that news organizations also have a
monetary benefit in making their stories more interesting- even if that means
erring on the side of sensationalism instead of sticking to logic and facts.
There are both similarities and differences among conventional breeding,
mutagenesis aided breeding and transformation-directed modification of plant
genomes (often called "genetically modified"). All are, in fact, natural processes
that have been harnessed by humans. And all three are indistinct in nature.
In other words, they all are happening simultaneously and have been happening
for millions of years before humans existed.
Mutagenesis occurs naturally because there are natural sources of ionizing
radiation that can result in changes in an organism's genetic code. It also
occurs at a low level just because every organism's enzymes that reproduce and
repair DNA make "mistakes" at some frequency. Selection then sorts out the
detrimental changes from the beneficial ones.
"Genetic modification" also occurs naturally. Agrobacterium species and
plant viruses have been introducing "foreign" DNA into plants for many millenia.
In all cases, the differences that humans have brought can be thought of as
acceleration and direction. Humans have thought of ways to speed up natural
selection to make plants more adaptable to specific agricultural situations and
more nutritious or palatable to humans and animals. Rather than wait a
million years for the mutation that confers resistance to an herbicide or a pest,
mutagenesis allows you to find that mutation in a few years. Then the breeder
backcrosses or outcrosses repeatedly to isolate the one desired mutation from
the others that were either neutral or undesirable.
The persons I have met in agribusiness are keenly aware that food safety is
an absolute must. They realize that if any "GMO" food slipped through the
incredibly strict screens for safety, the effects on the company's reputation and
bottom line would be extremely costly. The little discussed fact is that
"GMO" food is safer and more wholesome than conventionally produced foods because
of the dramatic decreases in required pesticides and fungicides and the
greatly reduced levels of very hazardous natural toxins like aflatoxin (made by a
I think that the public should continue to scrutinize agribusiness and
academic laboratories, just as they should scrutinize their government and other
major industries. However, I also believe that the more the public understands
about the process of food and feed improvement performed by BASF and other
companies, the more they will not only welcome it, but demand it. I also believe
that many in agribusiness welcome constructive scrutiny, despite the
inconvenience of it.
Currently, there are many crops, including fruit crops, that are practically
untouched by these technologies that could greatly reduce pesticide
applications because it is too expensive to bring them to market. From a food safety
and environmental safety standpoint, that is really unfortunate.
