Zea mays Transcriptome or Gene expression


ABSTRACT: Nitrate is the major source of nitrogen available for many crop plants and is often the limiting factor for plant growth and agricultural productivity especially for maize. Many studies have been done identifying the transcriptome changes under low nitrate conditions. However, the microRNAs (miRNAs) varied under nitrate limiting conditions in maize has not been reported. MiRNAs play important roles in abiotic stress responses and nutrient deprivation. We used the microarray systems to detect miRNAs responding to the chronic nitrate limiting conditions in maize leaves and roots. Overall design: MicroRNAs (miRNAs) are small, endogenous RNAs that are regulators of gene expression in plants and animals. And, miRNAs have been known for years to be important for phosphate, sulphate and copper deprivation responses in plants. In Arabidopsis, small RNA deep sequencing associated with nitrate response had been analyzed. However, information about the way by which miRNA are regulated by abiotic stresses in general and by low nitrate in particular is unavailable for maize. In this study, we used SmartArrayTM microarray system to detect miRNAs responding to chronic nitrate limiting conditions in roots and leaves in maize. Leaf and root under normal and low nitrate conditions were analyzed with three biological replicates. So there are 12 samples in this study.
