Abstract:

The novelty of floral organ morphology serves as one of the critical indicators for the ornamental value of flowering plants. This article summarized the influences of relevant floral developmental genes, temperature, hormones, and other external factors on the floral organ variation of Rosa chinensis ‘Viridiflora’. Analysis indicated that the formation of unique floral organ traits in R. chinensis ‘Viridiflora’ was associated with the inherent characteristics of floral organs, external factors, and molecular mechanisms. Finally, suggestions were made for future research directions. (1) Conducting physiological and anatomical studies on the leaf-like structures of R. chinensis ‘Viridiflora’ to determine their evolutionary orientation. (2) Performing functional verification of the screened related genes to determine whether this gene can cause flower type variation. (3) Constructing interaction network diagrams illustrating relationships between genes. (4) Utilizing rose plant regeneration and genetic transformation systems to cultivate novel floral cultivars.

Key words: Rosa chinensis, Rosa chinensis ‘Viridiflora’, flower organ development, flower type, molecular mechanisms, physiology and biochemistry, breeding, research progress
