Seed Size is Controlled by Maternally Produced Small Rnas, Scientists Find
AUSTIN, Texas — Seed size is controlled by small RNA molecules inherited from a plant’s mother, a discovery from scientists at The University of Texas at Austin that has implications for agriculture and understanding plant evolution.
“Crop seeds provide nearly 70 to 80 percent of calories and 60 to 70 percent of all proteins consumed by the human population,” said Z. Jeff Chen, the D.J. Sibley Centennial Professor in Plant Molecular Genetics at The University of Texas at Austin. “Seed production is obviously very important for agriculture and plant evolution.” (more…)
