Abstract
Cereal crops are cultivated across diverse regions globally, facing numerous environmental challenges, with salinity posing a significant threat to their growth and productivity. Plants respond to salinity stress (SS) through various morphological and physiological mechanisms. Notably, root system architecture (RSA) has emerged as a crucial factor in aiding nutrient uptake and ensuring efficient water supply, reshaping plant responses, particularly under SS. However, assessing and visualizing RSA and growth patterns in different crops is more challenging than aboveground parts, often leading to neglect in research. Roots serve a dual role in SS: preventing Na+ (sodium) uptake from soil and its accumulation into shoots. This review highlights the impact of SS on remodeling RSA, encompassing phenology, cytology, and genetic regulation. It offers comprehensive insights into root architecture, functionalities, hormonal crosstalk, and agronomic strategies tailored for cereals crops. These insights aim to optimize resource capture, mitigate Na+ uptake—known to reduce yield in saline conditions—and explore potential avenues for engineering roots to circumvent SS.
期刊介绍:
The effects of stress on crop production of agricultural cultivated plants will grow to paramount importance in the 21st century, and the Journal of Agronomy and Crop Science aims to assist in understanding these challenges. In this context, stress refers to extreme conditions under which crops and forages grow. The journal publishes original papers and reviews on the general and special science of abiotic plant stress. Specific topics include: drought, including water-use efficiency, such as salinity, alkaline and acidic stress, extreme temperatures since heat, cold and chilling stress limit the cultivation of crops, flooding and oxidative stress, and means of restricting them. Special attention is on research which have the topic of narrowing the yield gap. The Journal will give preference to field research and studies on plant stress highlighting these subsections. Particular regard is given to application-oriented basic research and applied research. The application of the scientific principles of agricultural crop experimentation is an essential prerequisite for the publication. Studies based on field experiments must show that they have been repeated (at least three times) on the same organism or have been conducted on several different varieties.
