Shotgun proteomics profiling of chia seeds ( L.) reveals genotypic differential responses to viability loss.

Introduction: Exposure to elevated temperatures and relative humidity expedites the seed aging process, finally leading to seed viability loss. In this context, certain proteins play a pivotal role in safeguarding the longevity of seeds. However, the seedproteomic response to loss viability in Salvia hispanica L.

Extraction method impact on the physicochemical characteristics of lipids from chia nutlets applicable to long-term storage studies.

Lipids are relevant during the seed aging process, for which it is pertinent to choose an extraction method that does not alter their nature. Thus, three methods were applied to extract lipids from chia seeds: one used as reference (Soxhlet) and two at room temperature using hexane/ethanol (COBio) and hexane/isopropanol (COHar). The fatty acid composition and the tocopherol content of the oils were analyzed.

Longevity of preserved L. seeds: physicochemical characteristics.

Unlabelled: Ex situ conservation of plant biodiversity has been increasingly used to prevent further loss of genetic resources. Seed banks, for example, shelter the passport data of germplasm, preserved in detail, and made available for easy access, actions included in the FAO's Second Global Plan. We examined the deterioration of tomato seeds of different varieties stored for 10-year intervals at COMAV's genebank.
