Project description:1 g samples of maize seedling leaf bases were collected from the wild-type (Zheng58) plants and the mutants (bzu3-2). we undertook glycoproteomics analyses of the N-glycans. Based on the libraries of maize protein group and plant N-glycosylation modification in the Uniprot database, we identified 2,194 intact N-glycopeptides, and quantified 181 differentially expressed intact N-glycopeptides (DEGPs)

Project description:The goal of the experiment was to perform a large scale study of circadian regulation of gene expression in maize. To identify maize genes with expression regulated by the circadian clock, transcript levels in the aerial tissues of young maize seedlings were determined by transcriptional profiling with the Affymetrix GeneChip Maize Genome Array. Maize inbred B73 seedlings were grown inside Conviron growth chamber. B73 seedlings were grown for 7 days under 12 h light:12 h dark (LD) photocycles, 26° C temperature and 70% humidity. At the 8th day, seedlings were transferred to continuous light (LL) and were allowed to entrain completely for 24 h prior to tissue harvest following which tissue was harvested every 4 hours under LL conditions for a period of 48h. Therefore, for the circadian LL time course 12 time points were collected as follows (also defined as factors in the treatment section): ZT0 - 8:00 am/ subjective dawn/ Day1 ZT4 - 12:00 pm/ subjective mid-day/ Day1 ZT8 - 4:00 pm/ subjective late-day/ Day1 ZT12 - 8:00 pm/ subjective dusk/ Day1 ZT16 - 12:00 am/ subjective mid-night/ Day1 ZT20 - 4:00 am/ subjective pre-dawn/ Day1 ZT24- 8:00 am/ subjective dawn/ Day2 ZT28 - 12:00 pm/ subjective mid-day/ Day2 ZT32 - 4:00 pm/ subjective late-day/ Day2 ZT36 - 8:00 pm/ subjective dusk/ Day2 ZT40 - 12:00 am/ subjective mid-night/ Day2 ZT44 - 4:00 am/ subjective pre-dawn/ Day2 Tissue comprised of aerial portion of the seedlings (corresponding to tissue from the prop roots and up) for RNA isolation. Total RNA was isolated from the entire aerial portion of 7 day-old seedlings (corresponding to tissue from the prop roots and up) by Trizol extraction followed by Qiagen RNeasy columns and treatment with RNase-free DNase I (Qiagen; qiagen.com). RNA was isolated from 3 independent biological replicates was pooled. cRNA was generated from pooled total RNA from 3 biological replicates with the GeneChip One-Cycle Target Labeling kit according to the manufacturer’s recommendations (Affymetrix, affymetrix.com). The University of California, Berkeley Functional Genomics Laboratory hybridized samples to Affymetrix GeneChip Maize Genome Arrays and scanned the washed arrays as suggested by manufacturer. Probe sets called “Not Present” or “Marginal” on one or more microarrays were removed from the downstream analysis, as is common practice with circadian studies. Raw hybridization intensities were normalized across all twelve arrays using RMA express in Perfect Match mode. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Frank G.

Project description:Genome-wide and organ-specific landscapes of epigenetic modifications and their relationships to mRNA and smRNA transcriptomes in maize We report an integrated genome-wide analysis of DNA methylation, histone modifications, smRNAs and mRNA transcriptional activity, using maize as a model. We surveyed the epigenomes of the maize inbred line B73 in shoot and root tissue by Illumina/Solexa 1G parallel sequencing after digesting genomic DNA with a methylation-sensitive restriction enzyme and after conducting chromatin immunoprecipitations (ChIP) using antibodies that target specific histone modifications (H3K4me3, H3K9ac, H3K27me3, H3K36me3, respectively). Additionally, we profiled RNA pools (micro RNA (miRNA), siRNA and mRNA) using the same sequencing strategy.

Project description:Different forms of N can affect plant metabolism. Differences can be observed at physiological and transcriptional levels comparing maize 4-day-old maize seedlings tretaed for three days with three different N forms: protein hydrolysates (SICIT2000 Spa), inorganic nitrogen (NH4H2PO4) or a mixture of free amino acids.

Project description:Transcriptome analysis of root development related genes in terrestrial and hydroponic ramie. Ramie seedlings were cultivated in soil, and in hydroponic with the shoot-cutting propagation method. The root samples from hydrophonic ramie were collected from the early stage (5-day-old seedling) and the late stage (30-day-old seedling) of acquatic roots induction. The roots of ramie seedling cultivated in soil were also collected for comparative analysis. Our study represents the detailed analysis of ramie root transcriptomes with biologic replicates.

Project description:All above ground organs of higher plants are ultimately derived from specialized organogenic structures called shoot apical meristems (SAMs). It is comprised of pluripotent stem cells, which divide to regenerate themselves as well as to provide cells to form other organs such as leaves and stems. To study global gene expression in maize SAM and very young primordia (P0 and P1), RNA was extracted from both SAMs (SAMs per se plus P0 and P1) and above-ground portions of seedlings collected from 14-day old B73 seedlings. These RNA samples were labeled and hybridized with cDNA microarrays that have 14,400 informative spots from maize. Statistical analyses showed that approximately 6.3% and 6.5% of the tested genes were significantly (p <0.0001) up- and down-regulated, respectively. Several control genes, whose expressions were confirmed in the maize SAM in the previous studies, were also up-regulated (p <0.01). The significantly up-regulated genes involved many novel transcription factor genes and regulatory genes as well as some kinds of enzymes, suggesting these genes play important roles in meristem maintenance and the early stage of leaf development in maize. Interestingly, several retrotransposon-related genes were greatly up-regulated in the SAM. This finding raised the possibility that retrotransposons are involved in regulatory mechanisms of maize SAM. Keywords: cell type comparison design
