Global Transcriptome Analysis Revealed the Molecular Regulation Mechanism of Pigment and Reactive Oxygen Species Metabolism During the Stigma Development of Carya cathayensis.

ABSTRACT: Hickory (Carya cathayensis Sarg.) is a monoecious plant of the genus Carya of the Juglandaceae family. Its nuts contain a number of nutritional compounds and are deeply loved by consumers. Interestingly, it was observed that the color of hickory stigma changed obviously from blooming to mature. However, the molecular mechanism underlying color formation during stigma development and the biological significance of this phenomenon was mostly unknown. In this work, pigment content, reactive oxygen species (ROS) removal capacity, and transcriptome analysis of developing stigma of hickory at 4 differential sampling time points (S1, S2, S3, and S4) were performed to reveal the dynamic changes of related pigment, antioxidant capacity, and its internal molecular regulatory mechanism.
