Expression

Organism	Comment	Expression
Lolium perenne	expression of GS1 increases in response to nitrogen starvation. Re-addition of nitrogen as either nitrate or ammonium results in down-regulation of GS1a expression levels within 24 h, coinciding with increased tissue ammonium concentrations	additional information
