Breeding of Paeonia suffruticosa
INQUIRYIntroductions
Paeonia suffruticosa is a famous Chinese medicinal and ornamental plant with the reputation as the "King of Flowers". China is the center of peony origin, differentiation, and evolution, with nine species and more than 1,600 years of cultivation history. At present, the breeding techniques used for peonies are based on artificial systematic selection and natural variation. There are three main breeding objectives for peonies. The first is to improve the ornamental value, mainly achieved by enriching the flower color, extending the flowering period, and enhancing the fragrance. The second is to enhance the resistance of Paeonia suffruticosa, including cold resistance and resistance to pests and diseases. The third is to improve reproductive ability and cultivate varieties with early flowering.
Lifeasible is committed to using modern molecular breeding techniques and genetic engineering combined with traditional breeding techniques to continuously improve the target traits and select and breed tree peony varieties that meet the needs of industrial development.
What We Follow
We combined the current status of tree peony breeding and compared the differentially expressed genes of tree peony species by metabolomics and transcriptomics analysis to guide the molecular breeding of tree peonies.

What We Provide
Flower Color Improvement
Tree peony pigments are flavonoid pigments, mainly anthocyanins, flavonoids, and flavonoid glycosides. The chemical content affecting the color of tree peonies varies greatly in the petals of different species. Flavonoid-3',5'-hydroxylase is missing in the synthesis pathway in tree peony pigments. We are able to use molecular breeding technology to insert the gene encoding flavonoid-3',5'-hydroxylase into tree peony to produce the blue pigment delphinidin glycoside and breed a more stable blue tree peony. We are able to promote the production of purple tree peonies by enhancing the activity of enzymes that promote pigment production.
Floral Fragrance Improvement
Peony aroma's volatile substances are mainly terpenes, alcohols, and esters. The main types of fragrances are classified as grassy scent, woody scent, valley scent, and fruity scent. Our scientists have deeply explored the main components of the characteristic floral fragrance of different tree peony varieties and their biological pathways of synthesis. They are able to use molecular breeding techniques to regulate the synthesis pathways of different volatile substances to breed tree peony varieties with different fragrance patterns.
Flowering Time Improvement
We are able to use gene editing technology to regulate the expression of flowering genes based on the flowering induction pathway and the genetic regulatory network of flowering organ development in tree peonies, to extend the flowering time of tree peonies, and to breed varieties capable of flowering in autumn.
