Transcription profiling by high throughput sequencing of maize (B73) shoot-borne root stele response to local high nitrate stimulation

ABSTRACT: In this study RNA-sequencing was used to monitor gene expression changes in stele tissue of maize (Zea mays L.) shoot-borne roots in response to local high nitrate stimulation to gain a better understanding of the mechanisms underlying nitrate signal and lateral root development.M

Plants have evolved a unique plasticity of their root system architecture to flexibly exploit heterogeneously distributed mineral elements from soil. Local high concentrations of nitrate trigger lateral root initiation in adult shoot-borne roots of maize (Zea mays) by increasing the frequency of early divisions of phloem pole pericycle cells. Gene expression profiling revealed that, within 12 h of local high nitrate induction, cell cycle activators (cyclin-dependent kinases and cyclin B) were up  ...[more]
