Project description:Transcriptomic data was obtained from adults of the stink bug Nezara viridula to complement biochemical enzymatic activity analysis performed for digestive enzymes. Pooled reads from all sample types were used for de novo assembly of a reference transcriptome. After mapping reads to reference, differential expression was performed between the different tissues of the same diet or between the same tissue in different diets.

Project description:A frightening resurgence of bed bug infestations has occurred over the last 10 years in the US. Current chemical methods have been inadequate for controlling bed bugs due to widespread insecticide resistance. Little is known about the mechanisms of resistance present in US bed bug populations, making it extremely difficult to develop intelligent strategies to control this pest. We have identified bed bugs collected in Richmond, VA which exhibit both kdr-type (L925I) and metabolic resistance to pyrethroid insecticides. LD50 bioassays determined resistance ratios of ~6000-fold to the insecticide deltamethrin, with contact bioassays confirming cross-resistance to several other labeled formulations. To identify metabolic genes potentially involved in the detoxification of pyrethroids, we performed deep-sequencing of the adult bed bug transcriptome, obtaining more than 2.5 million reads on the 454 titanium platform. Following assembly, analysis of newly identified gene transcripts in both Harlan (susceptible) and Richmond (resistant) bed bugs revealed several candidate cytochrome P450 and carboxyesterase genes which were significantly over-expressed in the resistant strain, consistent with the idea of increased metabolic resistance. These data will accelerate efforts to understand the biochemical basis for insecticide resistance in bed bugs, and provide molecular markers to assist in the surveillance of metabolic resistance.

Project description:Genome/chromosome organization is highly ordered and controls nuclear events. Here, we show that the TATA box-binding protein (TBP) interacts with the Cnd2 kleisin subunit of condensin to mediate interphase and mitotic chromosome organization in fission yeast. TBP recruits condensin onto RNA polymerase III-transcribed (Pol III) genes and highly transcribed Pol II genes; condensin in turn associates these genes with centromeres. Inhibition of the Cnd2-TBP interaction disrupts condensin localization across the genome and the proper assembly of mitotic chromosomes, leading to severe defects in chromosome segregation and eventually causing cellular lethality. We propose that the Cnd2-TBP interaction coordinates transcription with chromosomal architecture by linking dispersed gene loci with centromeres. This chromosome arrangement can contribute to the efficient transmission of physical force at the kinetochore to chromosomal arms, thereby supporting the fidelity of chromosome segregation. Genome-wide distributions of condensin and Pol III factors in fission yeast.

Project description:RNA-directed DNA methylation (RdDM) plays an essential role in transposable element (TE) silencing in plants. In the Arabidopsis RdDM pathway, the DDR complex containing DRD1, DMS3, and RDM1, is necessary for recruiting Pol V to transcribe scaffold RNA. Although the role of DDR is known, the mechanism by which the DDR complex is regulated remains unexplored. Here, we demonstrate that the Anaphase Promoting Complex/Cyclosome (APC/C) monitors the assembly of the DDR complex by targeting DMS3 for degradation. We show that a subset of Pol V-dependent RdDM loci are de-repressed in apc/c mutants, accompanied by defective recruitment and transcription of Pol V. APC/C targets DMS3 for ubiquitination and degradation in a D box-dependent manner, and the D-box-mutated DMS3 fails to complement the dms3 mutant. Competitive binding assays shows that the dosage of DMS3 is critical for the assembly of the DDR complex, and in vivo gel filtration analysis shows that the assembly of both DDR and Pol V is compromised in the apc8 mutant. These findings uncover a safeguard role of APC/C-mediated DMS3 degradation in the assembly of the DDR complex, and provide a direct link between selective protein degradation and RdDM.
