Salicylic acid (SA), as a secondary phenolic metabolite with phytohormonal activity, is an important component of the plant defense system against biotic and abiotic stresses. The scale of industrial synthesis of SA in the world is constantly growing, it is used as an intermediate for the synthesis of drugs and dyes, it is also used in cosmetology, food industry, plant biotechnology, etc. Recently, it has been considered as a promising growth-regulating agent in crop production for decreasing harmful effects of biotic and abiotic stresses in plants. Over the past two decades, numerous data have been published concerning the metabolic pathways of SA synthesis and its signaling in plant immunity. It regulates and affects various stages of plant ontogenesis and metabolism: seed germination, flowering, stomatal movements, pigment synthesis, photosynthesis and respiration, ethylene biosynthesis, thermoregulation, the activity of antioxidant enzymes, nutrient absorption, membrane integrity and functioning, nodulation in legumes, synthesis of secondary metabolites, general growth and development of plants. Numerous studies have confirmed that endogenous SA and/or its derivatives are involved in stress responses to heavy metals (HMs), hyper- and hypothermia, salinity, water deficiency, and, primarily, pathogenic infections. In parallel with fundamental studies of regulatory functions of SA and/or its derivatives, new ways of their exogenous application are constantly discovered. The use of low concentrations of exogenous SA (0.1–0.5 mM) for seed priming or foliar treatment is reported as an economically viable alternative approach for increasing plant tolerance from both economic and environmental points of view. Exogenous SA leads to an increase in endogenous SA levels that induces plant adaptive responses by changing phytohormonal status, increased synthesis of a number of secondary metabolites (alkaloids, cyanogenic glycosides, phenolics, terpenes), by increasing activity of antioxidant enzymes. One of the main advantages of using SA in crop production is the ability to reduce the dosage of pesticides and fertilizers that are potentially harmful to the environment and human health. It is also reported that the use of SA in some cases may lead to negative results – growth retardation, sterility, and yield decrease; the causes of this phenomenon are actively investigated. Further studies are necessary to clarify the mechanisms of exogenic SA action and its use on various crops in different growing conditions. This review aims to analyze the recent data on SA, crop production, and biotechnology areas where it is possible to effectively apply the SA and/or its derivatives.

Kasugamycin (KSM), an aminoglycoside antibiotic, has been widely used as a natural fungicide to control plant diseases, particularly for managing rice blast. However, its uptake mechanism and transport in rice remain to be explored. In this article, rice seedlings were treated by the foliar spraying method, and the content of KSM in rice leaves, stems and roots under different treatments was detected by high‐performance liquid chromatography tandem mass spectrometry (HPLC‐MS/MS), respectively. Results showed that leaf‐applied KSM could be transported to the phloem and migrate to roots and stems after uptake by leaves. Concentration, temperature and pH had significant effects on the uptake of KSM. Compared with the control, the competitive inhibitors d‐glucose and phlorizin both inhibited the uptake of KSM, demonstrating that sugar transporter proteins were involved in the uptake process. The energy inhibitors dinitrophenol (DNP) and carbonyl cyanide chlorophenylhydrazone (CCCP) also significantly inhibited the uptake of KSM, indicating that the uptake of KSM required energy consumption. Thus, the uptake of KSM by rice was an active process involving sugar transporter proteins, and it could migrate downward through the phloem. This study contributes to the promotion of the scientific application of antibiotics and the biological control of crop diseases. It will also provide a theoretical basis for the development of root‐targeted pesticides and transport pesticides with phloem mobility.
