Method for screening molecular marker of cattle adapting to high altitude hypoxia and application thereof

Provided are a method for screening a specific molecular marker of cattle adapting to high altitude hypoxia, and use of the specific marker in screening cattle breeds or individuals suitable for survival in high altitude hypoxia. For the genetic characteristics of adaptation of cattle breeds to high altitude hypoxia, from the perspective of genome evolution, selection and adaptation, local cattle breeds distributed at high and low altitudes are selected, and multi-genome-selection-signal and genome-wide association analysis methods and strategies are integrated to screen a key gene and a molecular marker adapting to high altitude hypoxia. The detection method designed according to the key gene and the marker features high accuracy and easy operation during application. By the analysis of cattle breeds at different altitudes, gene ACSS2 related to adaptation to high altitude hypoxia and a haplotype thereof are found, and specific SNP that receives the strongest selection signal on the gene is located. The method has great significance and practical value for cattle molecule breeding.

A system for purifying rainfall runoff including a bar screen; a collection and diversion device; a filter channel; a grass ditch; and a water storage tank. The bar screen is disposed around the collection and diversion device for preliminarily filtering the road rainfall runoff. The collection and diversion device collects the road rainfall runoff and diverts early rainfall runoff to the filter channel, after the filter channel is full, later rainfall runoff is directly diverted to the grass ditch through open channels. The grass ditch includes a percolation bed capable of filtering the early and later rainfall runoff. The water storage tank is connected to the grass ditch via a guiding pipe, to receive the rainfall runoff effusing out of the grass ditch.
