During today's call, I mentioned a couple of items which may be interest to some of our members interested in biology. Gibberellic Acid is a plant hormone, which can cause astonishingly rapid growth in plants, even for a very small exposure on the seeds. This material has been known for over 100 years, but I'm not aware of how much research has been done on it. It's readily available, from a number of online sources (e.g., Amazon), at an affordable price. https://en.wikipedia.org/wiki/Gibberellic_acid Some speculation was mentioned about how it functions, and whether the functioning could be replaced by genetic engineering. Another enzyme of interest in increasing plant production is the enzyme RuBisCO, which is responsible for Carbon fixation, converting atmospheric Carbon Dioxide into Glucose. This is a quite complex enzyme, but is one of the limiting factors for Carbon fixation. One wonders whether genetic engineering might find a faster enzyme, which could dramatically increase the growth of plants. https://en.wikipedia.org/wiki/RuBisCO Anyway, for those biologically inspired (which I am not, being strictly into the physical sciences), these may be some areas of interest.
