    Pukacka S, Ratajczak E. Antioxidative response of ascorbate-glutathione pathway enzymes and metabolites to desiccation of recalcitrant Acer saccharinum seeds. J Plant Physiol. 2006;163:1259-66 pubmed
    ..The relationship between ascorbate and glutathione metabolism and their relevance during desiccation of recalcitrant Acer saccharinum seeds is discussed. ..
  2. Ratajczak E, Kalemba E, Pukacka S. Age-related changes in protein metabolism of beech (Fagus sylvatica L.) seeds during alleviation of dormancy and in the early stage of germination. Plant Physiol Biochem. 2015;94:114-21 pubmed publisher
    ..These results confirm the importance of protein metabolism for seed viability and the consequences of its reduction during seed ageing. ..
  3. 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. ..
  4. 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. Production and scavenging of reactive oxygen species in Fagus sylvatica seeds during storage at varied temperature and humidity. J Plant Physiol. 2005;162:873-85 pubmed
  6. 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. ..
