Abstract

COP1 (CONSTITUTIVE PHOTOMORPHOGENIC 1) is a highly conserved eukaryotic protein that functions as a central repressor in plant photomorphogenesis. As an E3 ubiquitin ligase, COP1 regulates various physiological processes by ubiquitinating and degrading specific substrates. In recent years, the multifunctionality of COP1 has garnered increasing attention, as it not only is involved in light signal transduction but also plays a critical regulatory role in plant growth and development, stress response pathways, and hormone signaling networks. Moreover, COP1 also participates in the cross-regulation of multiple signaling pathways, including light signaling, stress response, and hormone signaling, further highlighting its core position in plant environment adaptation and growth and development. This review systematically elaborates on the evolutionary conservation, structural features, and multifunctionality of COP1, with a focus on summarizing its molecular regulatory networks in growth, development, and stress responses, while exploring its potential applications in crop genetic improvement.

期刊介绍： The Journal of Plant Physiology is a broad-spectrum journal that welcomes high-quality submissions in all major areas of plant physiology, including plant biochemistry, functional biotechnology, computational and synthetic plant biology, growth and development, photosynthesis and respiration, transport and translocation, plant-microbe interactions, biotic and abiotic stress. Studies are welcome at all levels of integration ranging from molecules and cells to organisms and their environments and are expected to use state-of-the-art methodologies. Pure gene expression studies are not within the focus of our journal. To be considered for publication, papers must significantly contribute to the mechanistic understanding of physiological processes, and not be merely descriptive, or confirmatory of previous results. We encourage the submission of papers that explore the physiology of non-model as well as accepted model species and those that bridge basic and applied research. For instance, studies on agricultural plants that show new physiological mechanisms to improve agricultural efficiency are welcome. Studies performed under uncontrolled situations (e.g. field conditions) not providing mechanistic insight will not be considered for publication. The Journal of Plant Physiology publishes several types of articles: Original Research Articles, Reviews, Perspectives Articles, and Short Communications. Reviews and Perspectives will be solicited by the Editors; unsolicited reviews are also welcome but only from authors with a strong track record in the field of the review. Original research papers comprise the majority of published contributions.
