From the middle of 2024, Brazil began to experience a phenomenon known as La Ni\u00f1a. In Brazil, when La Ni\u00f1a is active, rainfall tends to decrease in the South (causing drought in many cases) and increase in the North and Northeast regions. In the Southeast and Central-West, on the other hand, there is no such clear correlation, but the chances of cold and rainy periods increase (FABBRI, 2024).<\/p>\n

Water deficit is one of the major causes of reduced agricultural productivity as it negatively affects plant growth and development (JOSHI et al., 2016; KOCH et al., 2019). The scarcity of water availability limits the maintenance of processes crucial to plant survival, promoting significant reductions in the yield of cultivated species by limiting maximum production potential (ANSARI et al., 2019; CONTI et al., 2019; CRUZ et al., 2023).<\/p>\n

Among the technologies currently being disseminated in the market to optimize productivity is the use of foliar fertilizers containing amino acids in their composition. Thus, the objective of these products is to provide more complete nutrition for plants, increasing productivity. The presence of amino acids aims to enhance nutrition by providing molecules that are used to form proteins. With amino acids readily available for absorption, the plant saves energy by synthesizing these compounds, which is why they are used in conjunction with other nutrients (ROSA et al., 2023).<\/p>\n

Furthermore, there are particular functions in which amino acids are present, such as in the formation of chlorophyll, growth and functioning of meristems, in fruiting, responsible for the fertility of the pollen grain, for the consistency of cell walls, in addition to providing the connection between the carbon and nitrogen cycle in plants, influencing the synthesis of sugars and proteins, among others (COLLA et al., 2015; NARDI et al., 2016).<\/p>\n

On the other hand, they can act as physiological modulators, acting on the signaling pathway for development processes and in defense against biotic and abiotic stresses (LAMBAIS, 2011). In this aspect, the application of amino acids does not aim to supply the blocks for protein synthesis, but rather to activate the physiological metabolism of plants, having an important anti-stress action (TEIXEIRA et al., 2017; ALFOSEA-SIM\u00d3N et al., 2020).<\/p>\n

Amino acids are organic, soluble, energetic and easily degraded molecules, synthesized from the process of nitrogen assimilation and photosynthesis in the glycolysis, citric acid cycle and pentose phosphate pathways. In total, plants produce 20 essential amino acids and in the absence of one or more essential amino acids the plant does not complete the life cycle (Revista Cultivar, 2024).<\/p>\n

The main function of amino acids in plants is the formation of proteins, which are formed from the union of amino acids. In general, there are more than 3,000 proteins in a single plant cell and to compose each protein, at least 70 amino acids are required. The main amino acids and their respective functions in plants are presented below, according to Revista Cultivar (2024).<\/p>\n
