Project description:In this study, we used a cross-species network approach to uncover nitrogen (N)-regulated network modules conserved across a model and a crop species. By translating gene network knowledge from the data-rich model Arabidopsis (Arabidopsis thaliana, ecotype Columbia-0) to a crop, rice (Oryza sativa spp. japonica (Nipponbare)), we identified evolutionarily conserved N-regulatory modules as targets for translational studies to improve N use efficiency in transgenic plants.

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.

Project description:Following the domestication of maize over the past 10,000 years, breeders have exploited the extensive genetic diversity of this species to mold its phenotype to meet human needs. The extent of structural variation, including copy number variation (CNV) and presence/absence variation (PAV), which are thought to contribute to the extraordinary phenotypic diversity and plasticity of this important crop, have not been elucidated. Whole-genome, array-based, comparative genomic hybridization (CGH) revealed a level of structural diversity between the inbred lines B73 and Mo17 that is unprecedented among higher eukaryotes. A detailed analysis of altered segments of DNA conservatively estimates that there are several hundred CNV sequences among the two genotypes, as well as several thousand PAV sequences that are present in B73 but not Mo17. Haplotype-specific PAVs contain hundreds of single-copy, expressed genes that may contribute to heterosis and to the extraordinary phenotypic diversity of this important crop.

Project description:Decreasing antenna size is regarded as a potential strategy to improve photosynthesis for higher yield potential. Reducing chlorophyll content has been used as a strategy to decrease antenna size. One of the commonly cited benefits of this strategy has been its ability to improve crop nitrogen use efficiency; however, field evidence for this so far is limited. Here we used a mutant, p35s-Ami-YGL1, which has a lower chlorophyll content and also lower antenna size, to study the impacts of modifying leaf chlorophyll content on tissue nitrogen content and nitrogen use efficiency of plants. We show that the nitrogen contents for different tissues, including the seed tissue, on a weight basis were increased in p35s-Ami-YGL1, together with a decrease in C: N. Concurrently, we found that tissue carbon content decreased, while the content of chlorophyll precursors increased. These results suggest that the observed increase in tissue nitrogen content in Ami-YGL1 does not reflect an increase in plant nitrogen absorption or use efficiency, rather it is a result of stunted carbon fixation capacity of plants. The observed increase in seed nitrogen content in Ami-YGL1 suggests a potential strategy to increase seed nitrogen content in crops.

Project description:PPARG ChIP seq analysis was conducted to determine genes bound by and potentially regulated by PPARG in the developing ovine conceptus. Determination of gene regulation by prostaglandins through PPARG helps to improve our understanding of early pregnancy events and provides a basis for strategies to improve fertility and reproductive efficiency in ruminants.

Project description:To increase crop yield without polluting the environment, improving crop nutrient efficiency is of great importance. The RSA of plants is centrally involved in nutrient use efficiency. Therefore, to uncover the molecular mechanisms that regulate RSA of maize under nutrient-deficiency conditions and to improve maize nutrient use efficiency based on this knowledge, we investigated the morphological changes and ribonucleic acid sequencing (RNA-seq) profiles of maize roots during growth under normal and N-, P-, and K-deficiency conditions. We analyzed the data in different aspects and verified the reliability of the RNA-seq data by real-time quantitative polymerase chain reaction (RT-qPCR). These results will provide theoretical support for improving plant nutrient use efficiency. The maize (Z. mays) inbred line DengHai 605 was used in this study. Provided for four treatment conditions: normal N, P, and K level (CK); potassium deficiency (K-DEF); nitrogen deficiency (N-DEF); and phosphorus deficiency (P-DEF). The experiments were carried out by combining sand culture with water culture. The standard for evaluating differential gene expression is fold change (FC) > 2 or FC < -2 and p value < 0.05.The numbers of DEGs under N-, P-, and K-deficiency conditions were 3494 (1801 up-regulated and 1693 down-regulated), 3424 (1761 up-regulated and 1663 down-regulated), and 1830 (827 up-regulated and 1003 down-regulated), respectively. A total of 1483, 1470, and 519 genes were specifically expressed under the N-, P-, and K-deficiency conditions, respectively.
