Grape pistil has an important influence on fruit size and ***,there were few studies on grape ovary,and the development process of the ovary is still ***,in this paper,four different grape varieties with different lengths of small inflorescences,namely‘Musct Hambourg’grape(Vitis vinifera),‘Concord’grape(Vitis labrusca),‘ShanPuTao’grape(Vitis amurensis)and‘GongNiang2Hao’grape(Vitis amurensis×Vitis vinifera)were used as test *** varieties ovary were significant differences by means of stereomicroscope,paraffin *** expression of ovary determining gene vvagamous(VvAG)and its development related genes VvCRABS CLAW(VvCRC)and vvagamous-like 11(VvAGL11)with similar functions during the development of different grape varieties were preliminarily explored using fluorescence quantitative *** relationship between VvAG and VvCRC,VvAG and VvAGL11 were analyzed using Y1H *** results showed that there were obvious abdominal sutures on the surface of expect for‘Musct Hambourg’grape,and existing poly *** ovary development of‘ShanPuTao’and‘GongNiang2Hao’grape was completed when the inflorescence length was less than 1 cm,while the‘Concord’and‘Musct Hambourg’grape were fully developed when the length of inflorescence was 3–4 and 4–5 cm,*** and VvCRC began to express in large quantities after the formation of stamen primordia,while VvAGL11 during the forming of ovule ***,VvAG and VvCRC mainly regulated the development of stamens and carpels and also promote the development of ovules,while VvAGL11 major regulated the development of *** promoters of VvCRC and VvAGL11 were bound by *** study provides an important theoretical basis for further research on the molecular mechanism of grape ovary development.
