The "methylation gene map" of cotton's egenesitical genes was first mapped by Chinese and American scientists.

30 issue of the journal Genomic Biology published an important study of cooperation between Chinese and American scientists: for the first time, they mapped the "methylation gene map" of cotton's ephemeral genetic genes, that is, the difference between more than 500 ephemeral genes between wild cotton and cotton cultivation, providing biotechnology companies with an important clue to the cultivation of high-yielding high-quality cotton through ephemeral modification breeding.
decades, scientists have found that the egesmological characteristics of many plants and animals can be regulated by both genetic methods based on changes in DNA sequences and genetic modifications using ethnological methods that do not alter DNA sequences.
these findings open up new pathways for plant and animal breeding, especially using egestic techniques that create new varieties without changing genes, avoiding questions and debates about GENETIC technology.
In the latest study, Professor Zhang Naive of Nanjing Agricultural University, in collaboration with Jeffrey Chen of the University of Texas, created a "methylation gene map" of cotton by comparing U.S. land cotton with wild cotton to identify a list of more than 500 genetic switches associated with the DNA methylation process.
DNA methylation is an important ephegenic modification process, and the new map information can provide ephemgenic genetic changes in cotton over a million years of evolution, helping researchers select new varieties with certain new characteristics, increasing cotton yields, and improving their drought, heat, or insect resistance.
researchers have found that a methylated gene in wild cotton prevents cotton from flowering, and that the gene in cotton grown has been de-methylated, causing cotton to change from a tropical plant to a universal crop that "homes" in most parts of the world, a key mutation that is not a genetic mutation, but an emptogenic mutation. With this latest "methylation gene map," breeding experts can target improved varieties using chemical methods or techniques such as CRISPR-Cas9, and the same method can be used to breed major crops such as wheat, coffee, potatoes and corn,
