    6.3.1.2 | down |
the activity of the enzyme is down-regulated under conditions of excess nitrogen through covalent addition of an AMP moiety to Tyr406 (MtGS numbering) by the regulatory enzyme, GlnE |

| 6.3.1.2 | down |
the expression of the high-affinity low-capacity isoform Gln-1;1 is reduced under high ammonium treatment conditions |

| 6.3.1.2 | down |
under drought stress, total GS activity in root and leaf decreases significantly in IR-64 seedlings in comparison to Khitish seedlings. The reduced GS activity in IR-64 leaf is mainly due to decrease in isozyme GS2 activity |

| 6.3.1.2 | down |
under drought stress, total GS activity in root and leaf decreases significantly in IR-64 seedlings in comparison to Khitish seedlings. The reduced GS activity in IR-64 leaf is mainly due to decrease in isozyme GS2 activity, which correlates with decrease in corresponding transcript and polypeptide contents |

ammonium and nitrate feeding significantly regulate GS2 transcripts in leaf. Starving or moderate nitrogen levels dramatically increase GS2 transcripts for 1 day, decreasing to a constant low level after 2-3 days, while sufficient nitrogen level of 7.5 mM has a minor effect throughout 3 days compared to controls. Glutamate feeding, significantly regulates GS2 transcripts in leaf by decreasing initially then increasing to higher levels than controls, and also in root, where it is up-regulated continuously |

beta-catenin regulates the expression of glutamine synthetase |

| 6.3.1.2 | more |
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 |

Gln-1;4 isogene expression is very low under all conditions, the isogene expression is induced at high ammonium condition in roots |

| 6.3.1.2 | more |
Gln2 isozyme expression is induced at high ammonium condition. The expression of GS2 isozyme is reduced in a double mutant gln1;1:gln1;2, especially under high ammonium condition |
