摘要

We analyzed the contents of 38 primary metabolites and 9 minerals in the leaves and roots of bell pepper (Capsicum annuum L. var. angulosum) to study metabolic responses to deficiency in nitrogen, phosphorus, potassium, calcium, or magnesium. Induced deficiencies of individual cations reduced the abundance of the other cations in both leaves and roots. Each nutrient-deficient condition was clearly grouped by principal component analysis, which also showed that leaves under cation-deficiency treatments were separated from those under non-cation-deficiency treatments. This was consistent with that a single cation deficiency decreased the levels of the other cations in leaves. Specifically, N deficiency reduced amino acids and organic acids in both tissues. The common response to P-, K-, Ca- or Mg-deficient conditions showed significant increases in the levels of amino acids in both tissues and organic acids in the roots. In the leaves, P- or Mg-deficient conditions reduced organic acids. Soluble carbohydrates were significantly increased under N-, K-, Ca- or Mg-deficient conditions in the leaves, whereas in roots under K deficiency. Notably, the level of -aminobutyric acid, an amino acid that helps protect against biotic and abiotic stresses, was increased threefold in leaves under K-deficient conditions and sixfold in roots under P-, K-, Ca-, or Mg-deficient conditions. These findings provide additional information about variations in metabolite and mineral abundance in bell pepper leaves and roots in response to mineral shortage.

Var。Agenulosum）的38个主要代谢物和9个矿物质的含量，以研究对氮，磷，钾，钙或镁的缺乏的代谢反应。诱导个体阳离子的缺陷降低了两种叶子和根部的其他阳离子的丰富。通过主要成分分析清楚地分组了每种营养素缺乏的病症，该分析也表明，在缺陷治疗下的叶片下与非阳离子缺乏治疗中的叶片分离出来。这与单一的阳离子缺乏减少了叶片中其他阳离子的水平。具体地，N缺乏症在两种组织中还原氨基酸和有机酸。对P-，K-，Ca或Mg缺陷条件的共同响应显示出根系组织和有机酸中的氨基酸水平的显着增加。在叶片中，p-或mg缺乏条件减少有机酸。在叶片中的N-，K-，Ca-或mg缺陷条件下可溶性碳水化合物显着增加，而在K缺乏的根部。值得注意的是， - 氨基丁酸的水平，有助于防止生物和非生物胁迫的氨基酸，在k缺陷条件下的叶片下增加了三倍，在p-，k-，ca-或mg缺乏条件下的根部中的六倍。这些调查结果提供了有关甜椒叶片和根部的代谢物和矿物丰度的变化的额外信息，以应对矿物短缺。
