@redoxgrows at the US Biostimulants Summit 2025 I had the opportunity to represent Redox Bio-Nutrients with a talk on nutrient efficiency, challenges of overfertilization, while presenting RDX-N (patented) powered by our RAM technology. #RDXN #NutrientEfficiency #YieldStability

The model of gene expression taught in school is highly misleading! Transcription factors are proteins that bind to DNA and then help repress, or activate, the expression of genes. Cells have hundreds of different types of transcription factors, each tuned to regulate different genes based on short snippets of DNA located near those genes. The basic model, taught in school, says that these transcription factor proteins float around the cell and, when they bump into a DNA sequence, either latch onto it strongly (CORRECT SITE!) or fall off quickly (WRONG SITE) and keep searching. All the other DNA in a cell is basically abstracted away as unimportant or irrelevant; mere background noise. But again, this model is naive! And a new paper, published in Cell, beautifully shows how the sequences SURROUNDING a transcription factor's binding site also matter a great deal. This won't be surprising to many biologists, as "cracks" in the standard two-state model began emerging decades(?) ago. Biologists have tagged transcription factors with fluorescent tags and then watched them move around living cells. And they have noticed that when transcription factors land in a "wrong" location in the genome, they skip or hop to a nearby location and repeat this until finally connecting with the "correct" sequence. So in other words, there are actually three states that a transcription factor can exist in: free-floating, "searching", or "bound." (More technically, transcription factors first do a 3D search, then latch onto DNA and do a 1D search to find the correct location.) For this new paper, though, scientists exhaustively quantified *how* the sequences flanking a transcription factor binding site influence the search of the protein. They did a huge in vitro experiment, wherein they placed a specific transcription factor with a known binding site, called KLF1, in a huge library of 11,812 different DNA sequences. These sequences had mutated "core" binding sites and variations in the flanking sequences. They also prepared negative controls. Then, these researchers measured the binding kinetics of KLF1 with each sequence to understand which bases in the flanking sites impact the 1D search. What they found is that KLF1 has a basically flat disocciation rate from its core sequence, but that the PROBABILITY that it finds this sequence depends a lot on the surrounding context. Even mutations located dozens of bases away from the core site matter a lot, either pushing KLF1 to "hop" faster to find the site, or "trapping" KLF1 and slowing down its search. These flanking sequences can cause up to a 40-fold variation in the affinity of a transcription factor for its target site! This is just one small part of the paper, though, so I encourage anyone interested to read the whole thing. It is challenging throughout.

🌱 Hormones Decide Whether Plants Partner With Beneficial Fungi🍄 Under stress, ethylene boosts SMAX1 to block mycorrhizal symbiosis, while improved conditions and karrikin reduce SMAX1 to restore the fungal partnership. Article: nature.com/articles/s4146… 📸 Confocal microscopy

This is my soybean field which was sown on June14. Now crop is ready for harvesting. I hope that I will get expected yield. I have not used any chemical fertilizer in this field.I believe that if soil is strong, then amount of chemical fertilizer will be less or not needed at all

American went to Costco and bought fresh wild sockeye salmon. The car ride home was about an hour, so the salmon started to get warm As it got warmer, look at the amount of paradises that came out of the salmon…..

@dromius @redoxgrows @carogutj @KartikyeV Excellent point. Yes, I am sure it affects it but since we are providing it at sowing, it is used by the plant by the time AM fungi would infect the roots during growing season. A gap between that and high mycorrhizal inoculum injection.
