Desert shrub's full genetic blueprint reveals family evolution clues
Climate Adaptation
This shrub belongs to the same plant family as spinach, beets, and quinoa, so understanding its genetic toolkit for surviving drought could inform breeding of tougher food crops.
Researchers sequenced the complete DNA found in two of this desert shrub's energy-producing parts: the mitochondria and the chloroplasts. Comparing these genetic blueprints to related plants helps scientists piece together the family tree of the Amaranthaceae, a large plant group that includes many food and forage crops adapted to tough growing conditions.
Key Findings
Complete mitochondrial and chloroplast genomes of Krascheninnikovia arborescens were assembled and characterized for the first time
Comparative genome analysis places the species within the evolutionary context of the Amaranthaceae family
The genomic data reveal features that clarify evolutionary relationships among related organelle genomes in the family

Gene editing removes 97% of celiac-triggering proteins from bread wheat
It could mean that people with celiac disease — roughly 1 in 100 worldwide — may one day safely eat bread made from real wheat, without sacrificing the taste...
Native plants are species that have evolved naturally within a specific region or ecosystem without human introduction, forming integral ecological relationships with local soils, climate, and wildlife over thousands of years. In plant science, studying native species provides critical insights
