Flower biology and molecular systematics in African Marantaceae

在赠款提交的第三年，非洲竹芋科的系统发育分析将完成，包括时间维度。将完成对来自加蓬实地工作的花卉生态数据的评估，完成形态学检查，并将分析和讨论这三个数据集的复杂性，重点是非洲竹芋科的辐射。应达到以下目标：·完成系统发育树和测试分子钟，以确定物种形成事件的日期。完成非洲竹芋科花多样性的比较分析，包括阐明在花柱张力建立和花粉转移到花蕾中的花柱凹陷期间花的合生组织，并根据花的形态、花生态测量和观察到的植物-传粉者相互作用建立授粉综合征。通过在分子树上“映射”选定的特征来重建花多样性的进化，特别是风格运动。·加蓬竹芋科四新种的分类学描述

In the submitted third year of the grant the phylogenetic analysis of the African Marantaceae will be finalized including a temporal dimension. The evaluation of the flower ecological data from the field work in Gabon will be finished, the morphological examination will be completed and these three datasets will be analysed and discussed in their complexity focusing on the radiation of the African Marantaceae. The following aims shall be reached:• Completion of the phylogenetic tree and testing of a molecular clock to date speciation events.• Completion of the comparative analysis of floral diversity in the African Marantaceae including theo clarification of floral synorganisation during the setting up of the style tension and pollen transfer onto the stylar depression in the bud ando establishment of pollination syndromes based on flower morphology, flower-ecological measurements and observed plant-pollinator interactions.• Reconstruction of the evolution of floral diversity and in particular of the style movement by 'mapping' selected characters on the molecular tree.• Taxonomical description of four new Marantaceae species from Gabon
