..These results confirm the importance of protein metabolism for seed viability and the consequences of its reduction during seed ageing. ..
Borek S, Paluch Lubawa E, Pukacka S, Pietrowska Borek M, Ratajczak L. Asparagine slows down the breakdown of storage lipid and degradation of autophagic bodies in sugar-starved embryo axes of germinating lupin seeds. J Plant Physiol. 2017;209:51-67 pubmed publisher
..One reason for the slower degradation of autophagic bodies was the markedly lower lipolytic activity in axes fed with asparagine. ..
Borek S, Kalemba E, Pukacka S, Pietrowska Borek M, Stawiński S, Ratajczak L. Nitrate simultaneously enhances lipid and protein accumulation in developing yellow lupin cotyledons cultured in vitro, but not under field conditions. J Plant Physiol. 2017;216:26-34 pubmed publisher
..This causes that the level of nitrate inside the developing lupin seeds is not elevated under field conditions. ..

Pukacka S, Ratajczak E, Kalemba E. The protective role of selenium in recalcitrant Acer saccharium L. seeds subjected to desiccation. J Plant Physiol. 2011;168:220-5 pubmed publisher
..An increase in glutathione reductase (GR) activity was also observed in embryonic axes of seeds treated with selenium and dried to 35 and 30% WC compared to non-treated samples. Selenium appeared to have no such effect on cotyledons. ..
