Biodiversity and technological-functional potential of lactic acid bacteria isolated from spontaneously fermented chia sourdough
(Elsevier, 2019-11)Chia, is a gluten-free, rich in proteins, oilseed that is “on trend” as an alternative ingredient in food production, adding nutritional value. As a reservoir of natural biodiversity, lactic acid bacteria development, ... -
Genetic diversity and population structure of the sweet leaf herb, Stevia rebaudiana B., cultivated and landraces germplasm assessed by EST-SSRs genotyping and steviol glycosides phenotyping
(BMC, 2019-10)Background: Stevia rebaudiana (Asteraceae), native from Paraguay, accumulates steviol glycosides (SGs) into its leaves. These compounds exhibit acaloric intense sweet taste which answers to consumer demands for reducing ... -
Exploring gene networks in two sunflower lines with contrasting leaf senescence phenotype using a system biology approach
(BMC, 2019-10)Background: Leaf senescence is a complex process, controlled by multiple genetic and environmental variables. In sunflower, leaf senescence is triggered abruptly following anthesis thereby limiting the capacity of plants ... -
