ATP + L-Asp + L-Gln | Helianthus annuus | 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 | AMP + diphosphate + L-Asn + L-Glu | - |
