Hygroscopic awns in grasses and the hazards of extrapolation: Spikelet characters shaped by fire and soil in Hyparrhenia (Poaceae) but not its relatives

Here we use complete chloroplast data to help understand trait evolution across the a large clade of Andropogoneae. We expand our sampling to create the most detailed dataset for this group which provides a powerful phylogenetic framework for answering adaptive ecological questions.

本研究采用完整叶绿体数据，以阐明蜀黍族（Andropogoneae）这一大演化支的性状演化规律。我们扩大了样本采集范围，构建了该类群迄今为止最为详尽的数据集，为解答适应性生态学相关问题提供了强有力的系统发育框架。
