Plumbaginaceae is a highly stress-tolerant angiosperm family consisting of approximately 15 genera of which the genus Limonium is the largest. Many species of Limonium (also called sea lavender and statice) are of commercial importance in ornamental horticulture, especially for cut flowers. It is taught herein that it is possible to generate Limonium plants via somatic embryogenesis and in turn provide a means for repetitive embryogenesis. This repetitive property allows perpetuation of the embryogenic state indefinitely and thereby produce large numbers of Limonium embryos for diverse goals such as mass propagation, production of valuable compounds and for the production of transgenic plants.

The invention discloses a soybean MADS-box gene and applications thereof in floral organ modification, belonging to the field of biotechnology. GmMADS1, transcription factor in nucleus, is expressed in all the floral organs of four circles and, however, expressed in large quantity in petals and stamens, tobacco expressing excessive GmMADS1 increases the number of sepals, stamens and petals, a transformation from the sepals and the stamens to the petals is formed, as a result, the occurrence of cracking petals and bending stamens etc. causes the stamens to fail to come into contact with pistils, thus normal pollination and normal anther dehiscence cannot be realized and pollen activity is lowered. The above results represent that GmMADS1 plays an important regulation and control role in determining the position and the number of the petals and the development of male organs. New floral organ-variant material, resulted from the GmMADS1 gene, can be used for the breeding of crops and ornamental horticulture plants.
