Polyploid Plant Culture System Establishment

Chromosome polyploidy is a prominent feature of adaptive change and species formation. It is not only associated with the formation of many species but is also important for further differentiation within individual families and genera. Polyploid breeding is one of the most important ways to obtain new varieties and has obvious advantages for improving the nutritional organs of asexually reproducing crops. Due to the doubling of chromosome number, polyploid plants generally have gigantism of roots, stems, leaves, and flowers and fruits, and along with the gigantism of polyploids, their nutrient content and resistance to stress are enhanced.

Figure 1. The diagram illustrates the factors that can cause genomic duplication and formation of unreduced gametes. (Tamayo-Ordóñez M.C., et al., 2016)

For example, when polyploid breeding is applied to medicinal herbs, it can improve the biological yield of the corresponding parts of the medicinal herbs that are used in medicine, enhance plant resistance, and provide a stable genetic basis for survival and competition under adverse conditions. Therefore, polyploid breeding not only expands new resources but also provides a new possibility for the development and utilization of plants.

What We Offer

We have established a complete and comprehensive tissue culture regeneration system involving hundreds of species. Based on the existing platform, Lifeasible has established a simple and rapid plant polyploid induction technology system using artificial induction methods to provide customers worldwide with solutions for the cultivation of polyploid plants. As plant ploidy increases, the content of secondary metabolites in most polyploid species changes accordingly, so our customers can not only obtain polyploid plants under our polyploid induction system but also obtain more target metabolites.
