The DEGs of pathways related to nitrogen transport and assimilation: CPS: carbamoyl phosphate synthase; GS: glutamine synthetase; GOGAT: glutamate synthase; GDH: glutamate dehydrogenase; AsuS: argininosuccinate synthase; ASL: argininosuccinate lyase; Ure: urease; PUT: putrescine; SPDS: spermidine synthase; SPD: spermidine; SPM: spermine; AMT: ammonium transporter; NR: nitrate reductase; red represents the transcripts positively regulated by urea treatment; blue represents transcripts negatively regulated by urea treatment
