Cheer (salvia hispanica) It is one of the most popular nutrient-dense foods and pseudocereals of the Lamiaceae family Lamiaceae. Chia seeds are rich in protein, polyunsaturated fatty acids, dietary fiber, and antioxidants. A team of scientists at Oregon State University has sequenced the chia genome, providing a blueprint for future research to exploit the nutritional and human health benefits of the chia plant.
Chia is an annual herbaceous plant in the Lamiaceae family, which also includes popular culinary herbs.
It is grown in southern Mexico and Central America for its nutrient-rich seeds containing protein, polyunsaturated fatty acids, dietary fiber, antioxidants, and minerals.
Compared to dietary fiber sources such as soy, wheat, and corn, chia seeds contain approximately 54g of dietary fiber per 100g, of which 93% is insoluble fiber.
Similarly, 60% of the total fatty acids are composed of polyunsaturated fatty acids, and proteins constitute 18–24% of the seed mass.
Additionally, the health-beneficial effects of chia seeds on improving muscle lipid content, cardiovascular health, total cholesterol ratio, triglyceride content, and anti-carcinogenic properties have been demonstrated in humans and animals.
The high fiber content in chia seeds also helps to reduce hypoglycemic effects and stabilize blood sugar levels in people with type 2 diabetes.
Professor Pankaj Jaiwal from Oregon State University said, “Our study opens up the possibility for scientists to study chia seeds with a view to improving human health, while also expanding knowledge of chia’s full range of nutritional benefits.” We will continue to deepen our understanding.”
“Long-term food and nutritional security currently requires diversifying human diets through breeding and genetic improvement of nutrient-rich so-called minor crops like chia,” said Dr. Sushma Naisani of Oregon State University. We have reached a stage where this is necessary.”
In the study, the authors assembled a haploid chia genome with an estimated genome size of 356 Mb.
They identified genes and genetic markers in chia that could help agricultural researchers breed plants to amplify plant traits valuable to human health.
They discovered 29 genes involved in the biosynthesis of polyunsaturated fatty acids and 93 genes that aid chia seeds’ gel-forming properties.
They also found 2,707 genes highly expressed in the seeds that are likely to produce small biologically active peptides (biopeptides) derived from proteins.
When seed proteins are digested in the intestinal tract, these small biopeptides are released and absorbed into the body, with potential properties that may help alleviate human health conditions such as type 2 diabetes and high blood pressure. Masu.
“This is the first report in silico “Annotation of plant genomes for protein-derived small biopeptides associated with improved human health,” the researchers said.
of findings It was published in the magazine Frontiers of plant science.
