Abstract
Auxin response factors (ARFs) are an important family of transcription factors involved in the exertion of auxin in plants and play a key role in regulating the growth and development of plant nutritional and reproductive organs such as roots, stems, leaves, flowers, fruits, and seeds. Foods of plant origin occupy an important place in the nutritional structure of the human diet, and the main edible parts of different plants vary. In this paper, we review recent research reports on ARFs and summarize its role in the regulation of leaf, flower, root, and fruit growth, as well as other important life activities. We also present the challenges and opportunities that ARFs will present in the future. It will be important to deepen our understanding of the mechanisms by which ARFs interact with other proteins or genes. In addition, it is worth considering that more technical tools should be put into the study of ARFs and that the research should be oriented towards solving practical problems. In the future, it is expected that the nutrition and function of plant-derived foods can be improved through gene editing and other means.
Highlights
Auxin is the first discovered plant hormone, one that regulates plant growth and development extensively
The function of auxin depends on a signal transduction pathway involving a variety of transcription factors, one of the most important of which is auxin response factor (ARF)
Since the ARF was discovered in Arabidopsis in 1997, ARF has been found in Arabidopsis (Arabidopsis thaliana), rice (Oryza sativa), maize (Zea mays L.), tomato (Solanum lycopersicum), grapes (Vitis vinifera), and other plants
Summary
Auxin is the first discovered plant hormone, one that regulates plant growth and development extensively. Studies on the regulation of plant life through hormone signaling pathways have been carried out, and increasingly more genome-wide identification and expression analyses of ARF gene families in plants have been reported, as shown, which are of great significance for a more comprehensive understanding of the functions of ARF. We summarize recent research reports on the regulatory role of ARF in plant growth, discuss the key roles of ARF in the development of a variety of important organs in plants, propose challenges and opportunities for current ARF-related research, provide inspiration and references for future ARF research, and lay the foundation for the establishment of a functional network of auxin response factors
