|a The use of compost tea is important to improve food safety. However, the effect of compost tea on N uptake and partitioning in tomato is unclear. In this study, we measured temporal and spatial changes in nitrogen content, enzyme activities, and expression levels of nitrogen transporters genes in different organs of tomato treated with five nutrient solutions. The results showed that the expression levels of ammonium transporter protein genes (AMT1s) increased and that of a nitrogen transporters gene (NRT2.1) decreased under treatment with compost tea, which promoted NH4+ transport to the fruit and reduced nutrient wastage compared with the response to chemical fertilizers. In addition, the lowermost leaves on the stem showed reduced nitrate content, faster metabolism, and decreased chlorophyll a content, but fruit yield was not increased, in compost tea-treated plants. These changes were dependent on the expression level of the glutamine synthetase gene (GS1.1), which was increased in leaves and decreased in fruit. Compost tea influenced the expression of critical genes in the fruits and leaves, and improved the competitiveness of sexual reproductive growth as a sink for nitrogen. However, the benefits of compost tea were reduced when it was mixed chemical fertilizers. This research establishes a theoretical framework for optimization of organic vegetable cultivation and promoting the widespread production of organic crops
