Uniconazole-induced starch accumulation in the bioenergy crop duckweed (Landoltia punctata) II: of pathways involved in carbohydrate metabolism and endogenous Conclusion: The increase of endogenous ABA and CK levels positively promoted the activity of ADP-glucose pyrophosphorylase (AGPase) and chlorophyll content, while the decrease in endogenous GA levels inactivated Liu et al. Biotechnology for Biofuels (2015) 8:64 DOI 10.1186/s13068-015-0245-8China Full list of author information is available at the end of the articleα-amylase. Thus, the alterations of endogenous hormone levels resulted in starch accumulation due to regulation of the expression of genes involved in the starch metabolism pathway
