Morphological observation and protein expression of fertilized and abortive ovules in Castanea mollissima

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.
