Project description:Maize LOB30 (Zm00001d036435) is a transcription factor and is specifically expressed in anthers. Our previous RNA-seq data showed that expression of some genes were upregualted in maize lob30 mutant maize anthers. To confirm these genes are the downstrem target genes, we generated proLOB30: GFP-LOB30 transgenic maize lines, collected stage 9 to stage10 anther materials and performed ChIP-seq using the GFP antibody.

Project description:Species within nearly all extant animal lineages are capable of regenerating body parts. However, it remains unclear whether the gene expression programme controlling regeneration is evolutionarily conserved. Brittle stars are a species-rich class of echinoderms with outstanding regenerative abilities, but investigations into the genetic bases of regeneration in this group have been hindered by the limited available genomic resources. Here, we report a chromosome-scale genome assembly for the brittle star Amphiura filiformis. We show that the brittle star displays the most rearranged genome amongst echinoderms sequenced to date, featuring a reorganised Hox cluster reminiscent of the rearrangements observed in sea urchins. In addition, we performed an extensive profiling of gene expression throughout brittle star adult arm regeneration and identified sequential waves of gene expression governing wound healing, proliferation and differentiation. We conducted comparative transcriptomic analyses with other invertebrate and vertebrate models for appendage regeneration and uncovered hundreds of genes with conserved expression dynamics, notably during the proliferative phase of regeneration. Our findings emphasise the crucial importance of echinoderms to detect long-range expression conservation between vertebrates and classical invertebrate regeneration model systems.

Project description:The barley brittle stem mutants, fs2, designated X054 and M245, have reduced levels of cellulose compared with their isogenic parents Ohichi and Shiroseto. A custom-designed microarray, based on Agilent technology and including genes involved in cell wall metabolism, was used to compare transcript levels in the mutant and parental lines. For both mutants, the microarray revealed a marked decrease in mRNA for the HvCesA4 cellulose synthase gene in specific zones of stem internodes, and this was confirmed by quantitative PCR.

Project description:Most endogenous siRNAs in Arabidopsis are dependent on RNA-DEPENDENT RNA POLYMERASE 2 (RDR2) for their biogenesis. Recent work has demonstrated that the maize MEDIATOR OF PARAMUTATION1 (mop1) gene is a predicted ortholog of the Arabidopsis RDR2 gene. The mop1 gene is required for establishment of paramutation and maintenance of transcriptional silencing of transposons and transgenes, suggesting the potential involvement of small RNAs. We analyzed small RNAs in wildtype maize and in the isogenic mop1-1 loss-of-function mutant using Illumina’s sequencing-by-synthesis (SBS) technology, which allowed us to characterize the complement of maize small RNAs to considerable depth. Similar to rdr2 in Arabidopsis, in mop1-1, the 24 nt (nucleotide) endogenous heterochromatic short-interfering siRNAs were dramatically reduced resulting in an enrichment of miRNAs and trans-acting siRNAs (ta-siRNAs). In contrast to the Arabidopsis rdr2 mutant, the mop1-1 plants retained a highly abundant heterochromatic ~22 nt class of small RNAs. These data suggest that maize, unlike Arabidopsis, has a second mechanism for heterochromatic siRNA production. The enrichment of miRNAs and loss of 24 nt heterochromatic siRNAs in mop1-1 should be advantageous for miRNA discovery as the maize genome becomes more fully sequenced.

Project description:S. frugiperda fed with bx3 maize mutant and its control genotype B73 AND fed with bx1 maize mutant and its control genotype H88. The bx1 mutant is derived from the insertion of a Mu element within the Bx1 gene in a H88 genetic background (Hamilton 1964). Similarly, the bx3 mutant was obtained in the genotype B73 by insertion of a Mu element in the Bx3 gene (Frey, Chomet et al. 1997).

Project description:Purpose: The goal of this study is to identify differentially expressed genes (DEGs) in immature ears between Barren inflorescence3 (Bif3) mutant and its wild-type siblings in maize. Methods: the 3-4 mm ear primordia of maize wild-type and Bif3 mutant were dissected from maize plant at the reproductive stage, and samples were snap freeze using liquid nitrogen. The total RNAs were prepared using RNeasy mini kit (Qiagen). All those RNA samples of wild-type and Bif3 mutant were submitted for RNA-Seq. Conclusions: Our RNA-seq experiments identified 1380 up- and 242 down-regulated genes (P < 0.05, FDR < 0.1, fold-change > 1.5).
