Abstract

A transition from qualitative to quantitative descriptors of morphology has been facilitated through the growing field of morphometrics, representing the conversion of shapes and patterns into numbers. The analysis of plant form at the macromorphological scale using morphometric approaches quantifies what is commonly referred to as a phenotype. Quantitative phenotypic analysis of individuals with contrasting genotypes in turn provides a means to establish links between genes and shapes. The path from a gene to a morphological phenotype is, however, not direct, with instructive information progressing both across multiple scales of biological complexity and through nonintuitive feedback, such as mechanical signals. In this review, we explore morphometric approaches used to perform whole-plant phenotyping and quantitative approaches in capture processes in the mesoscales, which bridge the gaps between genes and shapes in plants. Quantitative frameworks involving both the computational simulation and the discretization of data into networks provide a putative path to predicting emergent shape from underlying genetic programs.

利用形态计量学将植物的基因与形状联系起来。
形态计量学领域的发展促进了形态学从定性到定量描述符的过渡,形态计量学代表了形状和模式到数字的转换。使用形态计量学方法在大形态尺度上对植物形态进行分析,量化通常被称为表型的东西。对具有不同基因型的个体进行定量表型分析反过来又提供了一种建立基因和形状之间联系的手段。然而,从一个基因到形态表型的路径并不是直接的,有指导性的信息在生物复杂性的多个尺度上发展,并通过非直觉的反馈,如机械信号。在这篇综述中,我们探讨了用于在中尺度捕获过程中进行全植物表型分析的形态计量学方法和定量方法,这些方法弥合了植物中基因和形状之间的差距。定量框架既包括计算模拟,也包括将数据离散到网络中,为预测潜在遗传程序的紧急形状提供了一条假定的途径。
