Application Notes
Arabidopsis thaliana (Col-0) and (Ler) possess a relatively low level of seed dormancy, and it is most often broken by stratification (2-6°C) in the dark for 2-4 days.
This formulation contains 1/2X MS (M524) with 0.5 g/L MES, and 10 g/L of sucrose and meets what the ABRC (Arabidopsis Biological Resource Center) recommends (https://abrc.osu.edu/seed-handling) for Arabidopsis seed germination.
This formulation also contains enough nitrogen (20 mM in nitrate) and carbon (30 mM in sucrose) for proper seedling growth and development (Martin et al. 2002). As Arabidopsis thaliana is a model flowering plant, this type of formulation has been used often for germinating seeds (Denness et al. 2011; Stacey et al. 2006; Sorek et al. 2014).
If you prefer 1X MS for Arabidopsis germination, we would suggest using M530 (contains M519 + 0.5 g/L MES) and add 10 g/L of sucrose (Valvekens et al. 1988; Millet et al. 2010). To add Gamborg’s vitamins add 1 mL/L of G219.
