Soybean agriculture and genetic transcription

Findings published in The Plant Cell showed recent advancements in genomic research led by researchers from Purdue University. There was a conventional understanding that each gene had a single transcription initiation site. The research led by Jianxin Ma, discovered that over 97% of previously predicted transcription initiation sites are incorrect, and that soybean genes exhibit different transcription initiation sites. These alternative sites allow the transcription factors to bind in different locations, causing different proteins to be produced from the same gene.

The researchers used STRIPE-seq technology which allowed for clear mapping of the initiation sites across the genome. This data will be incorporated into SoyBase, a database that stores genomic information of soybean by many different researchers. Many other researchers share crucial information for the breeding and cultivation of soybeans. A post-doc researcher from Chilvers lab at Michigan State U created a large, free, publicly available database to show plant breeders trends in resistance and gene efficacy in different regions. Austin went as far as using google translate from old surveys from China and South America that were not in English (which is not a monumental task, as the article might lead you to believe), to produce a better and more complete database of phenotypic data and responses to different stressors.

Soybean seams to be a very collaborative field of science that I would have never expected to have such completeness and level of study. I suppose most agricultural companies nowadays benefit from scientific research for the development of crops and soil as farming becomes more and more pressurized for rises and demands in efficiency. Having 97% of pieces of genomic data corrected is, however, an extremely interesting turnover of the previous literature understanding of this variable.

Don't Stress: Avoid BPA, Eat Soy

This article details the findings of North Carolina State University which reported that exposure to chemical biphenol A, or BPA, in developmental stages can result in high levels of anxiety due to the changes it induces in the amygdala region of the brain. Even more interesting is the fact that the results of the research found that soy effectively mitigates these effects. Dr. Heather Patisaul, an associate professor of biology NC State, explained how BPA was known to cause anxiety in a variety of species, however the exact mechanism by which BPA caused this anxiety was not well known. The study was conducted on a population of rats, and the results clearly displayed that the changes in gene expressions in the amygdala, a region which mediates responses to fear and stress, were a result of exposure to BPA, and that the population which was fed a soy diet had a significantly reduced stress level in comparison to the population which was fed a soy-free diet.

As one of my professors once told me, the two most tested populations are lab rats/mice and college students, so when I saw that research had been conducted on one of the possible causes of stress within a population, I was extremely intrigued. In one of my current classes, we had discussed the phytoestrogens which soy contains, and I found it interesting how it could it applied in this case. I was also quite worried with the amount of BPAs that the article noted were contained in consumer food containers, and if additional research would reveal if, and how, inclusion of BPA’s in consumer products could have resulting effects on human health. I look forward to how additional research may impact how soy could now have new medical applications as well as how the impact of BPA on stress levels may cause industry to move away towards lowering concentrations of the chemical.
