The invention discloses a stigma-exertion gene of a plant medicago truncatula flower organ as well as an encoded protein and application thereof. A gene is shown in any one DNA molecule of the following (a1) to (a4): (a1) a DNA molecule shown in a coding region such as SEQ ID NO. 1; (a2) a DNA molecule shown in SEQ ID NO. 3; (a3) a DNA molecule by hybridizing with a DNA sequence defined by (a1) or(a2) under stringent conditions and encoding a DNA molecule of a protein of claim 1; (a4) a DNA molecule derived from the medicago truncatula and having 90% or more homology with the DNA sequence defined by (a1) or (a2) or (a3). The gene can control the stigma exsertion and petal fusion of the plant; and lay a theoretical foundation for studying the regulation of the stigma exsertion of a CABL2 gene in plants. 本发明公开了种植物蒺藜苜蓿花器官柱头外露基因及其编码的蛋白与应用。该基因如下(a1)-(a4)中任所述的DNA分子：(a1)编码区如SEQ ID NO.1所示的DNA分子；(a2)SEQ ID NO.3所示的DNA分子；(a3)在严格条件下与(a1)或(a2)限定的DNA序列杂交且编码权利要求1所述蛋白质的DNA分子；(a4)来源于蒺藜苜蓿并且与(a1)或(a2)或(a3)限定的DNA序列具有90％以上同源性的DNA
