Nearly everything you know about plants was first discovered in a plant you’ve likely never heard of: Arabidopsis thaliana. Arabidopsis has taught us how plants respond to light, which hormones control plant behavior, and why some plants grow long, deep roots while others grow them shallow and wide. But despite its beloved reputation among plant biologists worldwide, many elements of the Arabidopsis life cycle have remained a mystery. Salk Institute researchers have now established the first genetic atlas to span the entire Arabidopsis life cycle, from single seed to a mature plant, capturing the gene expression patterns of 400,000 cells. The publicly available resource will help expand research and development in plant biotechnology, agriculture, and environmental sciences.
