The invention discloses application of an MtUNUSUAL FLORAL ORGANS gene to the regulation and the control on the leaflet quantity and the leaf-stem ratio of a leguminous plant. According to the application, a knockout mutant strain of the MtUNUSUAL FLORAL ORGANS gene in medicago truncatula is separated and obtained for the first time; proven through an experiment, the gene participates in the regulation and the control on the leaflet number and the leaf-stem ratio of the leguminous plant; a transgenic leguminous plant whose leaflet number and leaf-stem ratio are higher than those of a wild type plant is obtained through the way of over-expressing the gene; the MtUNUSUAL FLORAL ORGANS gene is over-expressed in the medicago truncatula of a compound-leaf species for the first time; the quantity of leaflets of 95 percent of compound leaves can be increased; moreover, the leaf-stem ratio can be increased by approximately 30 percent. The gene is proven to participate in the regulation and the control on the leaflet quantity and the leaf-stem ratio of the leguminous plant; the transgenic leguminous plant whose leaflet number and leaf-stem ratio are higher than those of the wild type plant can be obtained through over-expressing the gene; indicatively, after being implemented, the application is about to be used for creating a novel leguminous forage plant, can be used for subsequent forage quality, and has important significance to Chinese prataculture production.

The invention discloses a stigma exposed gene of the flower organ of the plant Medicago truncatula and its coded protein and application. The gene is a DNA molecule as described in any of (a1)-(a4): (a1) the DNA molecule whose coding region is shown in SEQ ID NO.1; (a2) the DNA molecule shown in SEQ ID NO.3; (a3) a DNA molecule that hybridizes to the DNA sequence defined by (a1) or (a2) and encodes the protein of claim 1 under stringent conditions; (a4) is derived from Medicago truncatula and is combined with (a1) or (a2) or ( a3) A DNA molecule with more than 90% homology to the defined DNA sequence. The gene of the invention can control the exposure of plant stigma and the fusion of petals; it lays a theoretical basis for the study of CABL2 gene regulating the exposure of stigma in plants.

The invention discloses a transcription factor gene that regulates the synthesis of plant flavonoids. The transcription factor gene is the MtbZIP10 gene identified from the leguminous plant Medicago truncatula, and its gene sequence is shown in SEQ ID NO.1. Moreover, the present invention discloses the function of the gene and its application. The advantage of the present invention is that the transcription factor gene that can positively regulate the synthesis of flavonoid compounds is cloned from the leguminous plant Medicago truncatula, and its function is systematically identified, and it is found that the gene can activate the biosynthesis pathway of flavonoids Multiple genes that increase the content of flavonoid compounds.
