Small alteration in the dna
WebbLow-phosphorus (low-P) stress has a significant limiting effect on crop yield and quality. Although the molecular mechanisms of the transcriptional level responsible for the low-P stress response have been studied in detail, the underlying epigenetic mechanisms in gene regulation remain largely unknown.

A non-sense mutation is any genetic mutation that leads to the RNA sequence becoming a stop codon instead. Now, missense mutations are a little different, and they're any genetic mutation that changes an amino acid from one to another.
