Abstract

Phosphorus (P) is a crucial macronutrient for plant growth and development, absorbed by plant roots as inorganic phosphate, which is frequently limited in soil. Plants use only 30 % of the total phosphate fertilizers applied to increase yield. Compared to other nutrients, the understanding of the molecular mechanisms involved in phosphate homeostasis in crops, particularly in the early transcriptional responses to change the root system architecture remain underexplored. Addressing these knowledge gaps requires studies that offer insights into the role of transcription factors in response to endogenous and exogenous signals associated with the nutritional status of crops. ASR (ABA, Stress and Ripening) proteins function as molecular chaperones, transcription factors, and homeostasis sensors. They also regulate the development and response to stress in plants. Our results show that ASR genes play an important role in phosphate homeostasis in rice (Oryza sativa L.) roots. Silencing of OsASR genes (OsASR-RNAi plants) delays development of adventitious and lateral roots, and alters the expression of genes associated with root development and the response to phosphate starvation. These findings suggest that OsASR play a role in regulating root system architecture, nutrient perception and signal transduction in rice plants.

期刊介绍： The journal Plant Stress deals with plant (or other photoautotrophs, such as algae, cyanobacteria and lichens) responses to abiotic and biotic stress factors that can result in limited growth and productivity. Such responses can be analyzed and described at a physiological, biochemical and molecular level. Experimental approaches/technologies aiming to improve growth and productivity with a potential for downstream validation under stress conditions will also be considered. Both fundamental and applied research manuscripts are welcome, provided that clear mechanistic hypotheses are made and descriptive approaches are avoided. In addition, high-quality review articles will also be considered, provided they follow a critical approach and stimulate thought for future research avenues. Plant Stress welcomes high-quality manuscripts related (but not limited) to interactions between plants and: Lack of water (drought) and excess (flooding), Salinity stress, Elevated temperature and/or low temperature (chilling and freezing), Hypoxia and/or anoxia, Mineral nutrient excess and/or deficiency, Heavy metals and/or metalloids, Plant priming (chemical, biological, physiological, nanomaterial, biostimulant) approaches for improved stress protection, Viral, phytoplasma, bacterial and fungal plant-pathogen interactions. The journal welcomes basic and applied research articles, as well as review articles and short communications. All submitted manuscripts will be subject to a thorough peer-reviewing process.
