Project description:Chinese Chestnut (Castanea mollissima BL.) has high nutritional and ecological value, so it is widely planted.However, the number of male flowers far exceeds the number of female flowers is an important factor limiting the yield of Chinese chestnut.A naturally occurring mutation in male catkin has been found on a Chinese chestnut tree in the mountains of Beijing, China.This mutant is shorter than the normal catkin.Studies have shown that this mutation can significantly reduce the number of male flowers, promote the differentiation of female flowers, and improve the yield of Chinese chestnut.In this research, we provided the RNA sequencing data of two groups of mutants and normal catkin.The comparative analyses of catkins transcriptomes presented here provides a valuable resource for discovery of genes and networks involved in the regulate the sex of the flower.
Project description:In this study, the Chinese chestnut ‘Huaihuang’ was used to explore the possible mechanisms of ovule abortion with respect to proteomics. The chestnut anthesis starts mid-June. The development of the burs of C. mollissima cv. ‘Huaihuang’ were monitored from 15 to 25 days after anthesis (DAA) And the burs for different times were collected from the Chestnut Experiment Station in Huairou District, Beijing, China. This experiment was conducted at the Beijing Protein Innovation Co., Ltd.
