          Abstract

          Abstract Chelates are nutrient-rich compounds that enhance the condition of plant tissues as micronutrients. Micronutrient deficiencies particularly iron (Fe) and zinc (Zn) leads to various problems for plant including chlorosis and necrosis etc. An adequate intake of Fe and Zn etc. is required by the human body. Biofortification of cereals with Fe and Zn is seen as a cost-effective solution to the problem of Fe and Zn deficiencies as well. In recent decades, many chelating compounds have been established and incorporated into agricultural systems. The most recent formulation involves the use of amino acids synthesized with one or more nutrient ions to improve fertilizer efficiency and better respond to environmental conservation. In addition to its primary function as a source of micronutrients, aminochelled are an active nitrogen (N) stimulant in plant nutrition, preventing the negative effects of basic N fertilizers like urea. The use of amino chelates, rather than just chemical fertilizers, has been shown to provide better production and quality as well as higher nutritional concentrations in several experiments. Furthermore, this review sheds light on various aspects of amino chelates fertilizers including types, history, and their effects on agricultural crops. In spite of amino chelates fast dominance in many countries’ fertilizer countries, there is not enough scientific data and knowledge on the specific reactions of plants to biotic and abiotic stresses from amino fertilizers.

          Resumo Os quelatos são compostos ricos em nutrientes que melhoram a condição dos tecidos vegetais como micronutrientes. Deficiências de micronutrientes, particularmente ferro (Fe) e zinco (Zn), levam a vários problemas para as plantas, incluindo clorose e necrose, etc. A ingestão de uma quantidade adequada de Fe e Zn, etc., é exigida pelo corpo humano. A biofortificação de cereais com Fe e Zn também é vista como uma solução econômica para o problema das deficiências de Fe e Zn. Nas últimas décadas, muitos compostos quelantes foram estabelecidos e incorporados em sistemas agrícolas. A formulação mais recente envolve o uso de aminoácidos sintetizados com um ou mais íons nutrientes para melhorar a eficiência do fertilizante e responder melhor à conservação ambiental. Além de sua função primária como fonte de micronutrientes, os aminoquelados são um estimulante de nitrogênio (N) ativo na nutrição das plantas, evitando os efeitos negativos de fertilizantes nitrogenados básicos como a ureia. O uso de aminoquelatos, ao invés de apenas fertilizantes químicos, tem mostrado proporcionar melhor produção e qualidade, bem como maiores concentrações nutricionais em vários experimentos. Além disso, a presente revisão lança luz sobre vários aspectos dos fertilizantes aminoquelatos, incluindo tipos, história e seus efeitos nas culturas agrícolas. Apesar do domínio rápido dos aminoquelatos em muitos países de fertilizantes, não há dados científicos suficientes e conhecimento sobre as reações específicas das plantas aos estresses bióticos e abióticos dos fertilizantes amino.

            The significance of amino acids and amino acid-derived molecules in plant responses and adaptation to heavy metal stress.

            Plants exposed to heavy metals accumulate an array of metabolites, some to high millimolar concentrations. This review deals with N-containing metabolites frequently preferentially synthesized under heavy metal stress such as Cd, Cu, Ni, and Zn. Special focus is given to proline, but certain other amino acids and oligopeptides, as well as betaine, polyamines, and nicotianamine are also addressed. Particularly for proline a large body of data suggests significant beneficial functions under metal stress. In general, the molecules have three major functions, namely metal binding, antioxidant defence, and signalling. Strong correlative and mechanistic experimental evidence, including work with transgenic plants and algae, has been provided that indicates the involvement of metal-induced proline in metal stress defence. Histidine, other amino acids and particularly phytochelatins and glutathione play a role in metal binding, while polyamines function as signalling molecules and antioxidants. Their accumulation needs to be considered as active response and not as consequence of metabolic dys-regulation.
