Phylogenetic reconciliation provides new insights into the evolutionary diversification of the glutamine synthetase gene family in seed plants. [PDF]
FEBS JPhylogenetic analyses of glutamine synthetase (GS) in seed plants revealed that all three major evolutionary lineages (GS2, GS1a, and GS1b) must have been present in the common ancestor, with GS2 being the first lineage to diverge. Unlike GS1b, GS1a and GS2 are usually single‐copy genes, even though they underwent duplications that resulted in ...

The Cinderella tree, <i>Quillaja saponaria</i> - A soap story. [PDF]
Plants People PlanetOur current understanding of plants has been shaped by the entwining of different cultures. The Chilean soapbark tree, traditionally valued as a source of natural soap, was shown by serendipitous research in France in the 1900s to produce compounds that can boost the immune response to vaccines.

Selected Properties ofAraucaria AngustifoliaandAraucaria AraucanaSeed Protein
International Journal of Food Properties, 2011 Araucaria angustifolia and Araucaria araucana are coniferous trees with large and nutritious seeds. The structure and nutritional properties of the proteins of these seeds were studied. About 70% of the proteins of the gametophyte were soluble in distilled water, although their solubility decreased drastically in raw seed flour.

Purification and Characterization of Two Major Lectins from Araucaria brasiliensis syn. Araucaria angustifolia Seeds (Pinhão) [PDF]
Plant Physiology, 1991 Two major lectins (lectin I and lectin II) were purified to homogeneity from the seeds of Araucaria brasiliensis (Gymnospermae). The purity of the lectins was confirmed by polyacrylamide gel electrophoresis, isoelectric focusing, and high performance liquid chromatography.

Viability of recalcitrant Araucaria angustifolia seeds in storage and in a soil seed bank [PDF]
Journal of Forestry Research, 2019 Abstract Araucaria angustifolia (Bertol.) Kuntze is a representative species of the Mixed Ombrophilous Forest in the Atlantic Forest Biome of Brazil. The development of a germplasm conservation protocol for long-term seed bank storage is compromised for this species, as it is sensitive to desiccation. Furthermore, in situ establishment of

Anatomical and Physicochemical Characterization of the Araucaria angustifolia Seed Coat [PDF]
Floresta e Ambiente, 2019 ABSTRACT Seed coat plays an important role in the embryo protection and seed germination. This study aimed to characterize the anatomical structure, histochemical and physicochemical aspects of the seed coat of Araucaria angustifolia Kuntze. Light and scanning microscopy usual procedures, and histochemical tests were used to describe and characterize ...

Ciência Florestal, 2010 The seeds of Araucaria angustifolia (Bertol.) Kuntze are recalcitrants and, therefore, they lose rapidly the viability after the harvest, limiting their use for nursery production of seedlings. This work was carried out to investigate the effects of cold
