Abstract：
Flowers are plant structures characteristic of the phylum Angiosperms composed of organs thought to have emerged from homologous structures to leaves in order to specialize in a distinctive function: reproduction. Symmetric shapes, colours, and scents all play important functional roles in flower biology. The evolution of flower symmetry and the morphology of individual flower parts (sepals, petals, stamens, and carpels) has significantly contributed to the diversity of reproductive strategies across flowering plant species. This diversity facilitates attractiveness for pollination, protection of gametes, efficient fertilization, and seed production. Symmetry, the establishment of body axes, and fate determination are tightly linked. The complex genetic networks underlying the establishment of organ, tissue, and cellular identity, as well as the growth regulators acting across the body axes, are steadily being elucidated in the field. In this review, we summarise the wealth of research already at our fingertips to begin weaving together how separate processes involved in specifying organ identity within the flower may interact, providing a functional perspective on how identity determination and axial regulation may be coordinated to inform symmetrical floral organ structures.
摘要：
花是被子植物门的特征性植物结构，该植物结构由被认为是从同源结构到叶子的器官组成，以专门实现独特的功能：繁殖。对称形状,颜色,和气味都在花卉生物学中起着重要的功能作用。花对称性的演变和单个花部分的形态（萼片，花瓣,雄蕊,和心皮）极大地促进了开花植物物种生殖策略的多样性。这种多样性促进了授粉的吸引力，保护配子，高效施肥,和种子生产。对称性,身体轴的建立，和命运的决定紧密相连。建立器官的复杂遗传网络，组织,和细胞身份，以及跨越身体轴的生长调节剂，正在该领域稳步阐明。在这次审查中,我们总结了丰富的研究已经在我们的指尖开始编织在一起，涉及指定器官身份在花可能相互作用的独立过程，提供有关如何协调身份确定和轴向调节以告知对称的花器官结构的功能观点。
