Regulation by sucrose of storage compounds breakdown in germinating seeds of yellow lupine (Lupinus luteus L.), white lupine (Lupinus albus L.) and Andean lupine (Lupinus mutabilis Sweet). II. Mobilization of storage lipid

Regulation by sucrose of storage compounds breakdown in germinating seeds of yellow lupine... Research of the regulatory function of sucrose in storage lipid breakdown was conducted on isolated embryo axes, excised cotyledons and whole seedlings of three lupine species grown in vitro on medium with 60 mM sucrose or without the sugar. Lack of sucrose in the medium caused significant increase in total lipid content in yellow, white and Andean lupine isolated embryo axes but in Andean lupine seedling cotyledons and excised cotyledons, lipid level was clearly lower in carbohydrates deficient conditions. Sucrose caused no significant effect on fatty acids spectra. The main fatty acid in yellow lupine seeds was linoleic acid, in white lupine oleic acid and in Andean lupine both oleic and linoleic acids. The main phospholipid in organs of three lupine species was phosphatidylcholine. In sugar-deficient conditions, content of phosphatidylcholine and some others phospholipids was decreased. The peculiar features of regulation by sugars of storage lipid breakdown in germinating lupine seeds and induction of autophagy in young carbohydrate starved embryo axes is discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Physiologiae Plantarum Springer Journals

Abstract

Research of the regulatory function of sucrose in storage lipid breakdown was conducted on isolated embryo axes, excised cotyledons and whole seedlings of three lupine species grown in vitro on medium with 60 mM sucrose or without the sugar. Lack of sucrose in the medium caused significant increase in total lipid content in yellow, white and Andean lupine isolated embryo axes but in Andean lupine seedling cotyledons and excised cotyledons, lipid level was clearly lower in carbohydrates deficient conditions. Sucrose caused no significant effect on fatty acids spectra. The main fatty acid in yellow lupine seeds was linoleic acid, in white lupine oleic acid and in Andean lupine both oleic and linoleic acids. The main phospholipid in organs of three lupine species was phosphatidylcholine. In sugar-deficient conditions, content of phosphatidylcholine and some others phospholipids was decreased. The peculiar features of regulation by sugars of storage lipid breakdown in germinating lupine seeds and induction of autophagy in young carbohydrate starved embryo axes is discussed.
