Rapeseed(Brassica napus)supplies about half of the vegetable oil in China.Increasing oil production and searching for genes that control oil content in the crop are research goals.In our previous studies,four major QTL for oil content located on A08,A09,C03 and C06 in the Ken C-8×N53-2(KN DH)mapping population were detected.The parental lines were resequenced to identify structural variations and candidate genes affecting oil content in these four major QTL regions.Insertion-deletion(In Del)markers were developed and used to narrow the regions.Differentially expressed genes located in the regions were investigated.GO and KEGG analysis showed that several genes were associated with lipid metabolism.Several transcription factors with higher expression in N53-2 than in Ken C-8 were identified.These results shed light on the genetic control of oil content and may be helpful for the development of highoil-content cultivars. 展开更多

Two-dimensional(2D)ferromagnetic materials have important applications in optics,spintronics,biomedicine,and energy conversion fields.To achieve higher integration and continue Moore's Law,it is necessary to search for 2D ferromagnetic materials.However,the low Curie temperature(Tc)of most 2D ferromagnetic materials seriously hinders their practical applications.Therefore,the search for room-temperature 2D ferromagnetic materials is of great significance for the advancement of technological applications.This article provides a systematic and comprehensive review of the synthesis methods of room-temperature 2D ferromagnetic materials that have been discovered and created to date,as well as an overview of the physical properties of the 2D ferromagnetic materials.Finally,the challenges and prospects of the room-temperature 2D ferromagnetic materials in the fields of synthesis and application are briefly summarized. 展开更多
