Nitrate and ammonium affect the overall maize response to nitrogen availability by triggering specific and common transcriptional signatures in root

Project description:Nitrogen (N) is an essential macronutrient for crops. Plants developed several responses to N fluctuations, thus optimizing the root architecture in response to N availability. Nitrate and ammonium are the main N inorganic forms taken up by plants and act as both nutrients and signals, affecting gene expression and plant development. In this study, RNA-sequencing was applied to gain comprehensive information on the pathways underlying the response of maize root, pre-treated in an N-deprived solution, to the provision of nitrate or ammonium. To assess the physiological response to these nutrients the shoot and root growth, the leaf pigment content and the amino acid amount in root and shoot were assessed. The analysis of the transcriptome shows that nitrate and ammonium regulate overlapping and distinct pathways, thus leading to different responses. NH4+ activates the response to stress, while NO3- acts as a negative regulator of transmembrane transport. Both the N-source repress genes related to the cytoskeleton and reactive oxygen species detoxification. Moreover, the presence of ammonium induces the accumulation of anthocyanins, while reduces biomass and chlorophyll and flavonoids accumulation. The profiles observed for hydrolysed and free amino acids highlighted common and distinct features in response to the two nitrogen forms.

Early transcriptional responses of Arabidopsis thaliana to ammonium and nitrate deprivation

Project description:Identification of the earliest transcriptional responses of adult Arabidopsis plant roots towards N-deprivation. Hydroponically grown Plants (35 days old) were 5 days adapted to nitrate or ammonium,respectively, as sole N-source to detect N-form specific transcripts. 24 Samples: 2 Pre-Treatments (5 Day adaptation to 3mM Ammonium/Nitrate) x 3 sampling time-points (0min, 15 min, 180 min) x 3 independent replications per time-point + 6 additional controls (2 x 15min, 1x 180min per Pre-Treatment)

Expression data from low nitrate culture in root in maize

Project description: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. Root is the organ that plants transport nitrate. we used the microarray systems to perform a genome-wide search to detect miRNAs responding to the chronic and transient nitrate limiting conditions in maize. 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 GeneChip® microarray systems to perform a genome-wide search to detect miRNAs responding to the chronic and transient nitrate limiting conditions in roots in maize.

Measuring transcriptional differences between Caulobacter crescentus cultured in nitrate versus ammonium as the sole nitrogen source

Project description:This study is measuring the steady-state levels of mRNA in wild-type Caulobacter crescentus grown in M2 defined medium containing either ammonium or nitrate as the sole nitrogen source. Four independent cultures of Caulobacter crecentus were grown in each of two medium conditions: M2(nitrate)glucose and M2(ammonium)glucose. Cultures in each medium type were grown to OD660=0.3 and RNA was isolated from each.
