Genome-Wide Identification and Characterization of microRNAs responding to ABA and GA in maize embryos during seed germination

(Submitter supplied) In this study, Three sRNA libraries were generated and sequenced from embryos treated with GA, ABA and ddH2O (CK). A total of 247 miRNAs (69 known and 178 novel ones) were identified and found that 28 known and 70 novel miRNAs were differentially expressed in embryos with different treatments. Using bioinformatics tool, we predict target genes of the differentially expressed miRNAs. GO enrichment and KEGG pathway analysis for these targets showed that miRNAs differentially expressed in the samples are involved in peroxisome, ribosome and plant hormonal signalling. more...

Genome-wide characterization of cis-acting DNA targets of ZmbZIP22 in maize

(Submitter supplied) A new factor binds to the 27-kD γ-zein gene promoter was identified through probe affinity purification and mass spectrometry analysis. This new factor belongs to bZIP type TF (hence named as ZmbZIP22). Chromatin immunoprecipitation coupled to high-throughput sequencing (ChIP-Seq) analysis with two biological replicates was performed to determine the DNA binding targets of ZmbZIP22. ChIP-Seq analysis detected 1,550 DNA binding sites distributed over 514 genes. more...

Defining the developmental program leading to meiosis in maize

(Submitter supplied) We isolated pre-meiotic and early meiotic cells from 24 maize anthers, covering a week of development from the day after archesporial (AR) cell specification to the early zygotene stage of meiotic prophase I. Starting material was staged by anther length, and anther stages were densely sampled from throughout this period. High quality reads were obtained from 144 cells.

THE DNA BINDING LANDSCAPE OF THE MAIZE AUXIN RESPONSE FACTOR FAMILY [DAP-seq]

(Submitter supplied) DAP-seq was used to generate genome-wide DNA:TF interaction maps for fourteen maize ARFs from the evolutionarily conserved class A ‘activator’ and class B ‘repressor’ clades. Among the distinct binding sites that were identified, we observed a high degree of overlap for ARFs of the same class, but found substantial differences in motif sequence, spacing, site preference, and association with auxin induced genes among clade A and clade B ARFs.

Opaque-2 regulates a complex gene network associated with cell differentiation and storage function of maize endosperm

(Submitter supplied) Development of the cereal endosperm involves cell differentiation processes that enable nutrient uptake from the maternal plant, accumulation of storage products and their utilization during germination. However, little is known about the regulatory mechanisms that link cell differentiation processes with those controlling storage product synthesis and deposition, including the activation of zein genes by the maize (Zea mays) bZIP transcription factor Opaque-2 (O2). more...

Silencing of Mu elements in maize involves distinct populations of small RNAs and distinct patterns of DNA methylation

(Submitter supplied) Epigenetic changes involve changes in gene expression that can be heritably transmitted to daughter cells in the absence of changes in DNA sequence. Epigenetics has been implicated in phenomena as diverse as development, stress response and carcinogenesis. A significant challenge facing those interested in investigating epigenetic phenomena is determining causal relationships between DNA methylation, specific classes of small RNAs and associated changes in gene expression. more...

Transcriptional characterization of maize roots in response to nitrate (NO3-), Water-Extractable Humic Substances (WEHS) and NO3-+WEHS.

(Submitter supplied) Soil humic substances are known to positively influence plant growth and nutrition. In particular, low-molecular fractions have been shown to increase NO3- uptake and PM H+-ATPase activity and alter expression of related genes. Changes in maize root transcriptome due to treatment with nitrate (NO3-), Water-Extractable Humic Substances (WEHS) and NO3-+WEHS were analyzed.

Distinguishing reproductive phasiRNAs in grasses from other identically-sized small RNAs using machine learning methods

(Submitter supplied) Small RNA libraries made from the rdr2/mop1 maize mutant, using RNA extracted from young ears (3 to 5 cm in length). Four libraries were constructed representing biological replicates. The mop1 mutant is depleted for heterochromatic siRNAs and enriched for 22-nt siRNAs of unknown function (as shown by Nobuta et al., 2008). These libraries were made in ~2010 but used for this study to assess the properties of the 22-nt, mop1-independent siRNAs. more...

Transcriptional responses of inbred lines B73, B75 and B96 and resulting F1 lines to herbivory by Tetranychus urticae

(Submitter supplied) The extreme generalist two-spotted spider mite, Tetranychus urticae, which is documented to feed on more than 1100 plant hosts, is becoming an increasingly important agricultural pest. Historically, as studies of plant-herbivore interactions have focused largely on insects, considerably less research has investigated plant responses to spider mite herbivores, especially in grasses. To identify intraspecific differences in maize response to T. more...

Transcriptome analysis of Htn1 mediated resistance against E .turcium

(Submitter supplied) Wall associated kinases (WAKs) have recently been identified as major components of fungal and bacterial disease resistance in several cereal crop species. However, the molecular mechanisms of WAK-mediated resistance remain largely unknown. Here, we applied the RNAseq approach to investigate the function of the maize gene ZmWAK-RLK1 (Htn1) that confers quantitative resistance to northern corn leaf blight (NCLB) caused by the hemibiotrophic fungal pathogen Exserohilum turcicum. more...

RNA polymerase mapping in plants identifies enhancers enriched in causal variants

(Submitter supplied) Promoter-proximal pausing and divergent transcription at promoters and enhancers, which are prominent features in animals, have been reported to be absent in plants based on a study of Arabidopsis thaliana. Here, our PRO-Seq analysis in cassava (Manihot esculenta) identified peaks of transcriptionally-engaged RNA polymerase II (Pol2) at both 5’ and 3’ ends of genes, consistent with paused or slowly-moving Pol2, and divergent transcription at potential intragenic enhancers. more...
