Mechanisms of plant adaptation to low phophorus stress
Phosphorus is one of the important limiting factors for plant growth and development.Soluble inorganic phosphate in soil is easily fixed by metal ions,resulting in poorly soluble phosphorus or organic phosphorus,causing low phosphorus stress.In order to adapt to the low phosphorus environment,plants develop a series of adaptive mechanisms,including morphological,physiological and biochemical responses.With the development of molecular biology technology,a large number of genes involved in plant phosphorus homeostasis,such as phosphorus transporter genes,PHR transcription factors,SPX transcription factors,and miRNAs,have been successively cloned,and their functions and mechanisms have been elucidated.These genes interact to form complex systemic and local phosphorus signaling regulatory networks that collectively regulate phosphorus homeostasis in plants.Here,we reviewed the effects of low phosphorus stress on plant growth and development,as well as the research progress on the molecular mechanisms and signal regulatory networks of low phosphorus stress.
