Role of asparagine and asparagine synthetase genes in sunflower ( Helianthus annuus) germination and natural senescence

Sunflower ( Helianthus annuus) contains three active asparagine synthetase (EC 6.3.5.4, AS) genes: HAS1, HAS1.1 and HAS2. Asparagine content and AS gene expression were determined during germination and leaf and cotyledon natural senescence to assess the role of asparagine as well as the extent of p...
