Project description:The environment plays important role in the interaction between plant hosts and pathogens. The application of chemical fertilizer is a crucial breeding technology to enhance crop yield since last century. As the most abundant fertilizer, nitrogen often increases disease susceptibility for crop plants. The underlying mechanism for nitrogen induced disease susceptibility is elusive. Here we found that nitrogen application activate gibberellin signaling by degradation of SLR1, the repressor protein in gibberellin signaling, which result in simultaneously promoting plant growth and disease susceptibility. SLR1, physically interacts with OsNPR1 and consequently facilitate OsNPR1 mediated defense responses. Transcriptome analysis showed that OsNPR1-SLR1 module plays a vital role in transcriptional reprogramming for both disease resistance and plant growth. Increase of SLR1 protein level in gibberellin deficient rice plants neutralizes disease susceptibility but sacrifice yield enhancement under high nitrogen supply. Mutation in SD1, encoding OsGA2ox2, produced more grains than WT，and maintains disease resistance under high nitrogen supply. Taken together, our work reveals the molecular mechanism underlying nitrogen-induced disease susceptibility, and demonstrates that the application of sd1 rice varieties prevent the tradeoff between disease susceptibility and yield increase under high nitrogen supply.

Project description:It is well documented that biostimulants could play an important role in agriculture. Additionally, increased fertilizer use efficiency is essential for maintaining both yield and grain quality, especially for bread wheat, which is a major global crop. In the present study, we explored the effects of mixing urea-ammonium-nitrate fertilizer with Glutacetine® on the physiological responses, agronomic traits and grain quality of winter wheat. Grain proteome analysis revealed that Glutacetine strongly reduced 11 proteins including storage proteins. Indeed, 2 alpha-gliadins and 2 avenin-like proteins decreased after Glutacetine application, which were good for celiac disease patients. Moreover, 2 glutenin HMW subunit were reduced, changing the gliadin/glutenin ratio and the HMW/LMW ratio, thus modifying the wheat flour dough quality. Our investigation reveals the important role of these formulations in achieving significant increases in seed yield and grain quality.

Project description:Nitrogen availability in the soil is a major determinant of crop yield. While the application of fertilizer can substantially increase the yield on poor soils, it also causes nitrate pollution of water resources and high costs for farmers. Increasing the nitrogen use efficiency in crop plants is a necessary step to implement low input agricultural systems. We exploited the genetic diversity present in the world-wide Arabidopsis thaliana population to study adaptive growth patterns and changes in gene expression associated with chronic low nitrate stress, with the aim to identify biomarkers associated with good plant performance under low nitrate availability. Transcription and epigenetic factors were identified as important players in the adaptatiion to limited nitrogen in a global gene expression analysis using the Affymetrix ATH1 chip.
