There is a very large diversity in plant architecture in nature. Over the past few years, novel theoretical concepts and analytical methods have emerged as powerful tools to understand important aspects of plant architecture. Plant architecture depends on the relative arrangement of three types of organs: leaves, shoots, and flowers. During plant development, the architecture is modulated by the balance of two homologous proteins: FLOWERING LOCUS T (FT) and TERMINAL FLOWER 1 (TFL1). The FT/TFL1 balance defines the plant growth habit as indeterminate or determinate by modulating the pattern of formation of vegetative and reproductive structures in the apical and axillary meristems. Here, we present a summarized review of plant architecture and primarily focus on the balance and its effect on plant form and development. We also propose passion fruit as a suitable model plant to study the effect of genes on plant architecture.
自然界中植物结构具有极大的多样性。在过去几年里，新的理论概念和分析方法已成为理解植物结构重要方面的有力工具。植物结构取决于叶、茎和花这三种器官的相对排列。在植物发育过程中，结构由两种同源蛋白——成花素（FT）和终端花1（TFL1）的平衡来调节。FT/TFL1平衡通过调节顶端和腋生分生组织中营养和生殖结构的形成模式来确定植物的生长习性是无限生长还是有限生长。在此，我们对植物结构进行简要综述，并主要关注这种平衡及其对植物形态和发育的影响。我们还提出西番莲作为研究基因对植物结构影响的合适模式植物。
