•15NH4+-fed tea plants accumulate more 15N than 15NO3−-fed plants.•Tea plants maintain a balanced concentration of NH4+ in tea leaves.•Genes involved in primary N assimilation is related to the lower assimilation of NO3−-than NH4+.•Balancing of NH4+ in tea leaves was obtained through theanine and ca...
