Dominant amino acids, organic acids and sugars in water-soluble root exudates of Csub4/sub plants: a mini-review

摘要

The aim of this mini-review was to identify the dominant carbohydrates, organic acids and amino acids in water-soluble root exudates of plants which represent dominant compounds there. The study is focused on plants of Csub4/sub-type of metabolism taking into account available literature. From group of carbohydrates, those dominant are represented glucose, fructose, arabinose and sucrose. Between dominant amino acids occurring in root exudates of Csub4/sub-metabolism plants are alanine, serine, arginine, glutamine, glutamic and aspartic acid, glycine, proline, cystine, lysine and g-aminobutyric acid. Citric, malic, tartaric, succinic, trans-aconitic represent the dominant organic acids. This knowledge may be useful for planning analyses of these compounds in root exudates of Csub4/sub plants. Except for this preparation of synthetic root exudates to simulate rhizosphere of Csub4/sub plants may be performed based on these results.
