GA Arabidopsis seed
Figure 7. Gibberellins (GA) contents in germinating Arabidopsis thaliana seeds and the effect of moist cold stratification.
(A) Important steps of GA biosyntheses, degradation and signalling.
(B) Endogenous contents of bioactive GA4 and GA1 in non-stratified germinating seeds incubated in the light at 22ºC.
(C) The effect of moist cold stratification on the endogenous contents of bioactive GA4 and GA1. GA-values of seeds imbibed in darkness (which inhibits germination) for 96 h are compared for 4ºC and 22ºC.
Results are from from Ogawa et al. (2003) (B) and Yamauchi et al. (2004) (C).
