现代主栽香蕉品种高度依赖营养繁殖,存在遗传基础狭窄、遗传多样性低等问题。芭蕉科现存约80个物种,不同类群在染色体基数(如 n =11、10和9)以及花苞颜色等性状上呈现多样性,是研究植物染色体结构演化和花器官性状分化的理想类群。然而,这些不同染色体基数的演化形成机制、染色体结构变异与花苞颜色分化的内在关联,长期以来缺乏基因组与细胞遗传学层面的直接证据。

Conventional microwave-absorbing coatings struggle to achieve broadband absorption over a wide range of angles while also serving structural purposes. Multistage metastructures offer more design flexibility, but it is difficult to optimize their many interacting geometric parameters. In a study published in Chemical Engineering Journal , a team led by Prof. WANG Zhenyang from the Hefei Institutes
