Male sterility (MS) has important applications in hybrid seed production, and the abortion of anthers has been observed in many plant species. While most studies have focused on the genetic factors affecting male sterility, the dynamic gene expression patterns of pollen abortion in male sterile lines have not been fully elucidated.

The palynology analysis carried out provides data about the composition and structure of the fossil vegetation. The main vegetation type was a mixed mesophytic forest dominated by Carya, Fagus, Betula, Quercus, and Ulmus. Accessory elements included Magnolia, Corylopsis, Liquidambar, Eucommia, Zelkova, Ulmus, Pterocarya, Juglans, Engelhardia, Platycarya, Symplocos, Araliaceae, Vitaceae, Hedera, Cornus, and Ilex. Mid- and high-altitude vegetation elements Tsuga, Abies, Keteleeria,...
