A major challenge in biology is to understand how organisms have increased developmental complexity during evolution. Inflorescences, with remarkable variation in branching systems, are a fitting model to understand architectural complexity. Inflorescences bear flowers that may become fruits and/or seeds, impacting crop productivity and species fitness. Great advances have been achieved in understanding the regulation of complex inflorescences, particularly in economically and ecologically important grasses and legumes. Surprisingly, a synthesis is still lacking regarding the common or distinct principles underlying the regulation of inflorescence complexity. Here, we synthesize the similarities and differences in the regulation of compound inflorescences in grasses and legumes, and propose that the emergence of novel higher-order repetitive modules is key to the evolution of inflorescence complexity.
生物学中的一个主要挑战是了解生物体在进化过程中如何增加发育复杂性。花序的分支系统具有显著差异，是理解结构复杂性的合适模型。花序上着生的花可能会发育成果实和/或种子，影响作物产量和物种适应性。在理解复杂花序的调控方面已经取得了重大进展，特别是在经济和生态上重要的禾本科植物和豆科植物中。令人惊讶的是，关于花序复杂性调控背后的共同或不同原则仍然缺乏综合论述。在这里，我们综合了禾本科植物和豆科植物中复合花序调控的异同，并提出新型高阶重复模块的出现是花序复杂性进化的关键。
