Breeding of Gerbera hybrida
INQUIRYIntroductions
Gerbera hybrida has become the fifth largest cut flower after the four major cut flowers in the world carnations, irises, moonflowers, and chrysanthemums. Gerbera hybrida has high ornamental value and is one of the important flowers in public green areas, residential areas, parks, and scenic spots. Gerbera hybrida is native to southern Africa and later gradually spread worldwide. Gerbera hybrida likes a warm, sunny, and light environment and air circulation. At present, the breeding work of Gerbera hybrida has gradually changed from conventional cross-breeding to the combination of cross-breeding and genetic engineering breeding. The breeding objectives are the improvement of flower color traits, the improvement of flower type traits, and the improvement of vase flower life.
Lifeasible is committed to using genetic engineering technology to produce new varieties of Gerbera hybrida with flower shapes and colors that meet consumer demand can produce flowers at low temperatures in winter and are resistant to fungal diseases.
What We Follow
With the continuous enrichment of transcriptome and genome data resources of Gerbera hybrida, our scientists have analyzed the transcripts related to benzopropane metabolism, other secondary metabolic biosynthetic pathways, phytohormone biosynthesis, and signal transduction processes, expecting to achieve the improvement of Gerbera hybrida traits through genetic engineering breeding, mutation breeding, and haploid breeding techniques.

What We Provide
Flower Color Improvement
The color change of Gerbera hybrida is caused by carotenoids and anthocyanins. We can use genetic engineering tools to regulate the expression of key genes in the pigment formation process to change the flower color of Gerbera hybrida. For example, the expression of the chalcone synthase gene was suppressed to produce a milky white variety of Gerbera hybrida.
Flower Type Improvement
The inflorescence of Gerbera hybrida is mainly composed of rays, trans, and discs. By analyzing the differentially expressed genes during the development of the floral phenotype of gerbera, we used genetic engineering tools to introduce the MASD-box gene into Gerbera hybrida, thus changing the flower structure.
Disease Resistance Improvement
Gerbera hybrida is generally cultivated in greenhouses, and the varieties are more susceptible to degeneration and pest damage. In breeding for resistance in Gerbera hybrida daisies, we can introduce the obtained virus resistance genes into gerbera daisies using Agrobacterium-mediated genetic engineering technology to produce disease-resistant varieties.
