Two auxinic herbicides alter Brassica napus changes in transcription in a time dependent manner

ABSTRACT: The aim of this study was to investigate the molecular background by using different growth conditions under which three different auxinic herbicides were administered. These were halauxifen-methyl, and picloram at thre different harvest points after treatments (2, 48, 96 hours). Hal treatment lead to the upregulation of translational processes after 2 h, whereas auxin and hormone responses were upregulated at 48h and 96 h. Photosynthesis and mitochondrial pro-cesses were downregulated through all time points. Further, after 48 h translation was downreg-ulated. Pic treatment induced the hormone / auxin response already after 2 h, and this continued for the other time points. At 2 h and 48 h after treatment the translational processes were down-regulated and photosynthesis was downregulated after 48 h and 96 h. The more detailed analy-sis of the auxin response in the datasets indicate a role for GH3 genes, genes encoding auxin efflux proteins and confirm the upregulation of the ethylene pathway.

Genome-wide maps of chromatin accessible regions in pluripotent (2iL) and differentiated (48h, 96h) mES cells

Project description:We report the application of sequencing technology for profiling of genome-wide chromatin accessible regions in mouse ES cells. We generated genome-wide chromatin-state maps of mouse embryonic stem cells maintained in pluripotent state (2iL) and differentiated for 48 and 96 hours (48 and 96). We find that the large majority of ESRRB motif-cointaining regions are found in 2iL and at 48 hours and that several formative genes contain time-specific oper regions at 48h, but not at earlier or later time-points.

Comprehensive transcriptome analysis of the synthetic auxin herbicide response in the problematic weed species Erigeron canadensis

Project description:Background: The auxin herbicides 2,4-D and dicamba are commonly used for management of horseweed (Erigeron canadensis L, (syn: Conyza canadensis L)). Halauxifen-methyl is a new auxin herbicide and recently commercialized to control several broadleaf weed species under a range of sites and environmental conditions. While synthetic auxin herbicides have been used for over 70 years, the precise mode of action that leads to plant death has yet to be clearly characterized. As new chemical families are discovered and the use of these herbicides continues to increase, it is imperative to understand how synthetic auxin active ingredients work within the plant to cause an herbicidal effect. Results: At 1 hour after treatment (HAT), 48 genes were consistently upregulated across the three herbicides, many of which are involved in the auxin-activated signaling pathway and response to auxin. At 6 HAT, 735 genes were upregulated by all herbicide treatments including genes associated with hormone signaling, metabolism, transport, senescence, and gene expression. The GO terms representing the 501 genes downregulated in all herbicide treatments were broadly categorized under two major groups: ATP and photosynthesis. At 6 HAT, over 50% of the genes differential expressed among the three herbicide treatments were unique to a single active ingredient. Conclusion: This research presents a first look into the differential gene expression profiles in horseweed following a foliar application of synthetic auxin compounds that represent three unique chemical families. While there are an abundance of transcriptome similarities induced by each herbicide that accounts for the general auxin herbicide response, distinct gene expression changes exclusive to each compound cannot be ignored as a contributor to the mode of action.

Microarray analysis of Indian mustard plants subjected to arsenate stress

Project description:In this study, time dependent (4 h to 96 h) transcriptome changes in roots and shoots of Brassica juncea were analyzed under arsenate (AsV) stress by using Agilent platform. A total of 1285 genes showed significant change in expression pattern upon arsenate (AsV) exposure. The genes belonged to various signaling pathways including hormones (jasmonate, abscisic acid (ABA), auxin and ethylene) and kinases. Significant effects were also noticed on genes of sulfur, nitrogen, CHO, and lipid metabolisms along with photosynthesis. These studies indicated interconnections among sulfur metabolism, jasmonate and kinase signaling pathways. Transcriptome results and biochemical analyses highlight that signaling and metabolic pathways work in a dynamic coordination to perceive and respond to the stress.

CRAC of yeast RNA polymerase II in anchor-away and auxin-degron strains.

Project description:We obtained RNA polymerase II occupancy profiles across the genome of S.cerevisiae strains: Abf1 anchor-away cells after addition of rapamycin for different time points (including no addition of rapamycin) and Rap1-AID auxin-degron cells after addition of auxin for different time points (including no addition of auxin) . This allowed us to compare polymerase occupancy profiles when these proteins are depleted from the nucleus or degraded.
