背景是从花粉产生到胚珠施肥的男性健身途径，被认为强烈影响动物授粉植物的生殖性状进化。该途径的特征是花粉损失的多种途径，可能导致男性健身的降低。但是，有关导致运输过程中花粉损失的机械过程的经验数据有限，因此我们对授粉过程中每个步骤的影响如何影响男性健康。范围本评论评估了研究植物中男性功能的历史，并确定了我们对花粉运输的生态学和进化的关键差距。我们沿着亲子关系途径的步骤探索男性生殖功能，并讨论克服成功障碍的进化选择。特别是，我们提出了一个新兴的想法，即传粉媒介的身体充当一个动态的舞台，促进了激烈的男性竞争，在该竞争中，竞争对手的竞争对手的花粉经常被竞争者覆盖或流离失所。这种观点将竞争性的舞台扩展到污名和风格的范围之外，并在研究男性生殖策略和花卉进化的研究中突出了重要的新突破的机会。
Background The male fitness pathway, from pollen production to ovule fertilization, is thought to strongly influence reproductive trait evolution in animal-pollinated plants. This pathway is characterized by multiple avenues of pollen loss which may lead to reductions in male fitness. However, empirical data on the mechanistic processes leading to pollen loss during transport are limited, and we therefore lack a comprehensive understanding of how male fitness is influenced by each step in the pollination process. Scope This review assesses the history of studying male function in plants and identifies critical gaps in our understanding of the ecology and evolution of pollen transport. We explore male reproductive function along the steps of the pathway to paternity and discuss evolutionary options to overcome barriers to siring success. In particular, we present a newly emerging idea that bodies of pollinators function as a dynamic arena facilitating intense male-male competition, where pollen of rival males is constantly covered or displaced by competitors. This perspective extends the pollen-competitive arena beyond the confines of the stigma and style, and highlights the opportunity for important new breakthroughs in the study of male reproductive strategies and floral evolution.
