Breeding of Eustoma grandiflorum
INQUIRYIntroductions
Eustoma grandiflorm consists of three wild species that are closely related. The wild species have single-petaled flowers, mainly consisting of purple, pink, white, and yellow. With the progress of research in the direction of the morphology of floral organ differentiation, genetics of flower color and flower type, reproduction and embryo development, analysis of saline-resistant gene expression, and cloning of C- class MAD-box gene of Eustoma grandiflorm, Eustoma grandiflorm breeding have become an important element of cut flower breeding. Currently, breeding scientists are aiming at breeding Eustoma grandiflorm with heavy petals, rose type, lily type, and different colors.
Lifeasible is committed to breeding varieties of Eustoma grandiflorum that are resistant to important diseases and have different flower colors, flower types, or fragrances through biotechnology such as genetic modification.
What We Follow
Completing Eustoma grandiflorum genome sequencing has provided tremendous support for breeding research. Expression profiling of Eustoma grandiflorum flower color regulation genes, morphological genes, and analysis of disease occurrence mechanism will help us to provide better breeding services to our customers. Our workflow is as follows.

What We Provide
Flower Color Improvement
Flower color is a key factor in attracting consumer choice in ornamental flowers, and genetics can be used to change the color of flowers and thus breed new varieties. Our work on flower color improvement for Eustoma grandiflorm has focused on the following areas.
- Green fluorescent protein is a fluorescent protein that emits light autonomously, is very efficiently expressed in plant cells, and is commonly used as a fluorescent dye for flowers. We have been investigating the effect of introducing green fluorescent protein into the genome of ornamental flowers on flower color.
- The biochemical modification of flavonoids is an important factor affecting the flower color of ornamental plants. We have successfully constructed the Eustoma grandiflorm genetic transformation system, which can affect auxin pigments by regulating the glycosylation and acylation of flavonoids, thus changing the flower color.
- We can use an Agrobacterium-mediated approach to transfer homologous antisense chalcone synthase cDNA into Eustoma grandiflorm to alter the color of flowers by regulating the anthocyanin synthesis pathway.
Floral Fragrance Improvement
Floral fragrance is determined by a complex mixture of low molecular weight volatile molecules released from plant organs. We have been exploring the use of genetic engineering techniques to introduce genes capable of encoding volatile molecules in Eustoma grandiflorm to improve the fragrance of flowers.
Flowering Time Improvement
Control of flowering time is an important issue for most ornamental flowers. We offer services to control the flowering time of Eustoma grandiflorm by transgenic methods. For example, the flowering time of flowers is shortened by overexpression of LEAFY, a gene from Arabidopsis thaliana that determines meristematic tissue.
