-
light, carbon and nitrogen availability control asparagine synthesis in sunflower by regulating three aspargine synthetase coding genes. HAS2 expression requires light and is positively affected by sucrose. HAS1 and HAS1.1 expression is dependent on nitrogen availability, while HAS2 transcripts are still found in N-starved plants. High ammonium level induces all three asparagine synthetase genes and partially reverts sucrose repression of HAS1 and HAS1.1

Helianthus annuus contains three asparagine synthetase genes: HAS1, HAS1.1 and HAS2. Most of the asparagine newly synthesized for germination and cotyledon expansion is due to HAS2 activity, with little contribution of the other asparagine synthetase genes. All three genes work together to synthesize asparagine for leaf senescence

role for hexokinase in the sugar-sensing mechanism that regulates PvNAS2 expression in roots, downregulation of the asparagine synthetase enzyme and concomitantly asparagine production. Thereby a favourable environment is created for the efficient transfer of the amido group of glutamine for the synthesis of purines, and then ureide generation.
