Araucaria angustifolia seeds are characterised by a relatively high content of starch and protein. This study aimed to verify the presence of α-amylase inhibitors in the seeds and to characterise a trypsin inhibitor found in the embryo tissues. Inhibitor purification was carried out by the saline

The megagametophyte of the Araucaria bidwillii seed is a storage tissue that surrounds and feeds the embryo. When all its reserves are mobilized, the megagametophyte degenerates as a no longer needed tissue. In this work we present a biochemical and a cytological characterization of the
In the present manuscript, we report on the proteolytic enzymes acting in the Araucaria bidwillii megagametophyte throughout seed germination. At seed maturity the megagametophyte contains a bulk of reserves for the growing embryo, thus representing the major storage tissue of the bunya pine seed.
Araucaria angustifolia is an endangered Brazilian native conifer tree. The aim of the present work was to identify differentially expressed proteins between mature and germinated embryos of A. angustifolia, using one and two dimensional gel electrophoresis approaches followed by protein
