Successfully sketch Aphid aphid gene map

The International Aphid Genomics has successfully sequenced the Aphid aphid genome sequence harmful to agriculture.

Based on the decoding of information for the Aphid aphid gene, scientists hope that in the future, a method to effectively prevent this aphid will be studied. The results are published on the website of the American Journal of Public Science and Biology Library on February 23.

Aphid is a small insect that mainly eats plant fluids, which not only attract nutrients of plants in each herd but also a 'broker' that transmits viruses to plants, damaging polarity Great for agricultural crops worldwide.

Aphid aphids have a close relationship with microorganisms, they can adapt to the changes of the environment and constantly switch between single and sexual reproduction, so they can be transformed into many. Different expression morphology.

Because Aphid aphids have very special biological characteristics, they also become important biological models in basic biology research.

The team of scientists from the International Aphid Genomics team sampled the DNA of the 'Pea Aphid' aphid in North America, then took advantage of the shotgun sequence method to conduct sequencing. their genes. The scientists then successfully mapped the genetic sequence map from about 450 million pairs of genes out of a total of 500 million pairs.

Scientists have taken advantage of computers to make genetic predictions, and conduct structural tests for a gene component in it to collate and modify with previously predicted results.

As a result, Aphid has about 35,000 genetic genes and is the species with the highest number of genes in the insect world. Certified scientists, Aphid aphids have a very special combination of genes, that is, they have many transcription genes and are the species with the highest number of transgenic genes in the insect world; Lack of many immune-related genes . Scientists believe that the detection of large numbers of transgenic genes is important for understanding the molecular basis of the characteristic especially in Aphid aphids.

We often use pesticides to prevent Aphid aphids, however the use of chemical drugs will be dangerous and harmful to human health and pollute the environment.

Successfully sketching the Aphid aphid gene map not only helps people learn more about the unusual biological characteristics of this insect, but also has a great influence in the areas of biology such as chemical evolution. , ecology, zoology and microbiology . /.
