摘要近世纪来,生物学家一直使用性状尺度关系(性状大小与体型大小的双变量散点图)来表征种群内的表型变异,并比较种群或物种之间的动物形状。标度关系是一种流行的度量标准,因为它们长期以来一直被认为反映了性状生长和发展的潜在模式。然而,产生动物缩放的生理机制还没有得到很好的理解,并且还不清楚缩放关系如何演变。在这里,我们回顾了发育生物学,遗传学和生理学的最新进展,因为它们涉及到控制成年昆虫身体部位的生长。我们总结了已知影响发育结构内细胞增殖速率或持续时间的四种机制,并提出这些机制的突变如何影响成人身体部位的相对大小。通过回顾这四个过程的已知信息,并说明它们如何有助于性状缩放模式,我们揭示了可能参与昆虫形态进化的遗传机制。
Abstract For almost a century, biologists have used trait scaling relationships (bi-variate scatter-plots of trait size versus body size) to characterize phenotypic variation within populations, and to compare animal shape across populations or species. Scaling relationships are a popular metric because they have long been thought to reflect underlying patterns of trait growth and development. However, the physiological mechanisms generating animal scaling are not well understood, and it is not yet clear how scaling relationships evolve. Here we review recent advances in developmental biology, genetics, and physiology as they pertain to the control of growth of adult body parts in insects. We summarize four mechanisms known to influence either the rate or the duration of cell proliferation within developing structures, and suggest how mutations in these mechanisms could affect the relative sizes of adult body parts. By reviewing what is known about these four processes, and illustrating how they may contribute to patterns of trait scaling, we reveal genetic mechanisms likely to be involved in the evolution of insect form.
