Greater Understanding of Plant Hormone Results in Stem Cells that Grow Shoots
Published:14 Jul.2017 Source:Science Daily
Researchers at Dartmouth College have identified how a well-known plant hormone targets genes to regulate plant growth and development. The finding could allow scientists to establish organ-growing stem cells for grains like rice and corn, and may ultimately lead to solutions to stubborn agricultural problems.
The study, appearing in the Proceedings of the National Academy of Sciences, describes how cytokinin activates the transcription factor ARR10 to control gene expression in the Arabidopsis plant-a member of the mustard family commonly used as a model in plant biology.
