Weeds pose a challenge to cotton production, and herbicides have been the primary means of control. However, there is growing concern over weed resistance to herbicides. To address this issue, we evaluated three cover crop species and six cotton accessions for weed suppression. The study found that hairy vetch, wheat, and B16 cotton CS line effectively suppressed Amaranthus species, while MNTN 4-15, B16, hairy vetch, and wheat were correlated with the highest cotton yield. Cover crops were also analyzed for chlorogenic acid content, with wheat, MNTN 4-15, and hairy vetch producing the highest amounts. The greenhouse tray study showed that …

mRNA molecules form an intermediate in the transfer of sequences from DNA to ribosomes in order to guide protein production. Errors can be introduced into mRNA, producing aberrant proteins which place a strain on cellular regulatory machinery, causing increased risks of apoptosis, cancer, and decreased fitness. These errors may be introduced due to decreased transcriptional proofreading capabilities, exposure to chemicals, or mistakes in RNA editing machinery. It is important to investigate these causes of transcription errors to better understand the long-neglected area of mRNA fidelity which has such significant impacts on our cellular functions. In this paper, it was determined …
