Role of cis-zeatin in root responses to phosphate starvation
In this work we show that root illumination influences Pi starvation responses, enhancing the root and shoot growth arrest and limiting the root/shoot ratio as well as root hair elongation.  A comparative transcriptomic study using dark-grown roots (DGR) roots seedlings taht were grown with or without phosphate identifies several genes that respond to Pi deficiency that were not previously reported, likely by the negative effect of the root illumination. Overall design: Random sequencing of poly A RNA from Arabidopsis thaliana wild type roots grown for 8 days in a medium 1/2MS with (+Pi 625 µM) or without (5 µM) of phosphate.
