Chestnut Blight-Resistant Breeding

INQUIRY

Chestnut blight is caused by an imported fungus called Cryphonectria parasitica. It creates cankers that girdle the trunk and kill the tree down to its roots. Lifeasible focuses on chestnut disease, recognizing the impact of chestnut disease on the chestnut industry, and aims to provide advanced biotechnology and reliable solutions to bring new hope for chestnut disease prevention and control.

Symptoms of Chestnut Blight

Chestnut blight main symptoms for the disease from the wound invasion, the initial formation of yellow-brown to brown spots, peeling the bark visible dark brown to black-brown cortex and discoloration of the death of the bast, when the seriousness of the spread of spots surrounded by the trunk, resulting in bark shrinkage and longitudinal cracking. The leaves on the affected branches turned brown and died, but did not fall off. As the spots expand, the bark cracks and falls off, exposing the xylem, which may eventually cause the death of the entire plant.

Screening and validation of disease resistance genes

We have developed several resistance gene markers for Chestnut Blight, and these markers have been successfully applied in genetic transformation experiments of chestnut blight by PCR to verify their feasibility in disease resistance breeding. In addition, we can realize rapid screening and verification of chestnut disease resistance genes by using molecular markers, thus improving the breeding efficiency.

Genetic improvement of the American chestnut

Traditional backcross breeding. We have guided researchers to utilize disease resistance genes of Chinese chestnut (Castanea mollissima) and introduce resistance genes into the genome of American chestnut (C. dentata) through multi-generation backcrossing. We have now developed hybrids with the disease-resistant phenotype of the Chinese chestnut and a morphology close to that of the American chestnut.

Genetic engineering technology

Transgenic technology. We have introduced disease resistance genes into American chestnut embryos through transgenic technology for American chestnut blight, and our transformed plants show resistance to chestnut blight.

Gene editing technology. We have established a comprehensive gene editing technology platform, utilizing advanced gene editing technology to edit the American chestnut genome and directly introduce disease resistance-related genes.

Highlight Our Advanced Technology Platform

Molecular detection technology platform We have established an advanced molecular detection technology platform that can quickly and accurately identify the pathogenic bacteria of chestnut disease and provide important support for prevention and control.
Rapid breeding technology platform We are constantly exploring ways to shorten the breeding cycle by inducing trees to bloom in one to two years instead of the usual five to eight years through supplemental lighting and fertilization. Our rapid breeding technology platform allows for faster breeding of selected trees and creates exciting possibilities for accelerating the breeding cycle.
Genetic transformation technology platform Through genetic transformation, we realize the stable expression of exogenous genes in the target chestnut and further provide technical support for chestnut gene editing.
