Orchids Versus Model Plants: A Comparison of Flowering Mechanisms

Flowering processes in orchids possess both similarities and differences with characterized model plant species, such as Arabidopsis . This review examines the complex mechanisms governing flowering in orchids, contrasting them with model species. While mechanisms of characterized models rely heavily on photoperiod and vernalization, orchids exhibit a more pronounced reliance on hormonal signaling, often overriding other cues. Seven flowering pathways were compared among model species and orchids, revealing species‐specific responses to temperature and photoperiod. Three models of orchid flower development were evaluated, highlighting their strengths and limitations and the need for species‐specific approaches. Understanding these complexities is crucial for developing effective conservation strategies and harnessing orchid diversity for horticultural applications, particularly in the face of climate change and the potential for genetic manipulation to enhance flower traits. The sophisticated sensory systems driving orchid pollination also warrant further investigation. A multidisciplinary approach integrating genomic data, advanced computational methods, and species‐specific analyses is essential for fully unlocking the secrets of orchid flowering.
