郭旺珍 脂肪酸 棉纤维发育
2023/10/28
脂肪酸和脂质对植物细胞伸长具有重要作用，其功能特征涉及维持细胞结构完整性，为多种代谢过程提供能量，作为信号转导介质参与多种信号通路等。脂质转运蛋白(LTP)是一种含有疏水腔的蛋白质，这种结构特征使 LTP 蛋白能够结合和转运复杂的脂类物质。棉纤维是世界上最重要的天然纺织原料，也是植物中最长的单细胞。脂类物质的含量及组成对棉纤维发育具有重要调节作用，其中神经酰胺类脂质在棉纤维伸长时期含量最为丰富,且...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Morrison-Kawamata cone conjecture for Calabi-Yau fiber spaces
Calabi-Yau fiber spaces 莫里森-川俣 锥猜想
2023/5/9
In this talk, I will explain the relationship between the Morrison-Kawamata cone conjecture for Calabi-Yau fiber spaces and the existence of Shokurov polytopes. For K3 fibrations, this enables us to e...
