Unraveling the Complexities of Flowering in Ornamental Plants: The Interplay of Genetics, Hormonal Networks, and Microbiome

In ornamental plants, one of the most complex life processes, i.e., flowering, is regulated by interaction between the microbiota, hormones, and genes. Flowering plays an integral role in overall development and is quintessential for reproduction. Considering its importance, this review explores the complex mechanisms that determine the induction of flowering, highlighting the relationship between hormonal and genetic networks as well as the growing significance of the microbiome. Important genes involved in genetic control include FT, SOC1, and LFY. These genes react to environmental stimuli like photoperiod and vernalization. Auxins, cytokinin, and gibberellins are only a few hormone pathways important for floral growth and timing. The importance of plant–microbe interactions has been emphasized by current research, which shows that the microbiome affects flowering through processes like hormone production and availability of food. A comprehensive understanding of flowering induction is possible by integrating results from microbiota, hormones, and genetics studies, which may improve the breeding and culture of ornamental plants. For researchers to understand the complexity of flowering in ornamental plants and develop unique breeding strategies and improved floral qualities, it is critical to use interdisciplinary approaches, as this comprehensive investigation demonstrates.
