Transcript profile analyses of maize silk strands during silk senescence

Project description:To fully characterize the extent of genomic changes in senescent silk, we performed a time-course tissue harvesting. Material was collected at four time points: 3-, 7-, 11- and 15 days after silk emergence (DASE). Maize inbred line B104; 2 cm of basal part of silk from rings 6-10

Identification of KIL1 targets via RNA-Seq in Zea mays

Project description:To understand how the NAC transcription factor KIL1 regulates age-induced senescence and cell death in maize silks, we need to get a genome-wide view on its downstream targets. We propose to compare the transcriptome profiles of GOF and LOF transgenic silk tissue with the profile of wild-type B104 silk. 1 cm of basal part of silk from rings 6-10 from plants harboring the dominant-negative repressor proSILK1:KIL1-SRDX, proSILK1:KIL1 overexpressing line, and wild type B104 will be harvested at 11 DASE. This will allow to compare and contrast the expression profiles of KIL1 LOF and GOF mutants with transcriptome data derived from wild type senescent silk.

Expression data provoked by H2O2 from plastid or peroxisomal origin

Project description:Reactive oxygen species (ROS) are key signalling molecules that regulate growth and development and coordinate responses to biotic and abiotic stresses. ROS homeostasis is controlled through a complex network of ROS production and scavenging enzymes. Recently, the first genes involved in ROS perception and signal transduction have been identified and, currently, we are facing the challenge to uncover the other players within the ROS regulatory gene network. The specificity of ensuing cellular responses depends on the type of ROS and their subcellular production sites. Various experimental systems, including catalase-deficient plants, in combination with genome-wide expression studies demonstrated that increased hydrogen peroxide (H2O2) levels significantly affect the transcriptome of plants and are capable of launching both defence responses and cell death events. We used microarrays to assess differential gene expression provoked by H2O2 from plastid or peroxisomal origin, respectively. Columbia-0 (Col-0, wild type), catalase-deficient Salk plants (10-15% of wild-type catalase activity; cat2-2; N576998; (Queval et al., 2007)) and A. thaliana plants expressing glycolate oxidase in chloroplasts (GO5 plants; (Fahnenstich et al., 2008)) were grown in soil under a 16h light/8h dark regime at photosynthetically active photon flux densities (PPFD) of 75 µmol quanta m-2 s-1 at 22°C day/18°C night temperatures and a CO2 concentration of 3,000 ppm. After three weeks of growth, plants were transferred to ambient CO2 concentration (380 ppm) and the same PPFD. Whole rosettes were harvested at 0h and 8h after transfer. Control samples were harvested at 8 h from plants continuously maintained in high CO2.

An ectopic network of transcription factors regulated by Hippo signaling drives growth and invasion of a malignant tumor model [larval imaginal discs (eye, wing and leg)]

Project description:Cancer cells have abnormal gene expression patterns, however, the transcription factors and the architecture of the regulatory network that drive cancer specific gene expression profiles is often not known. Here we studied a model of Ras-driven invasive tumorigenesis in Drosophila larval epithelial tissues and combined in vivo genetic analyses with high-throughput sequencing and computational modeling to decipher the regulatory logic of tumor cells. Surprisingly, we discovered that tumor specific gene expression is driven by a highly interconnected network composed of few transcription factors. These are: Stat, Mef2, the AP-4 homolog Cropped, the nuclear receptor Ftz-f1, the bHLH factors Myc and Taiman, and the AP-1 transcription factors Kayak, ATF-3, Pdp1, and dCEBPG. Many of these transcription factors are ectopically expressed and/or hyperactivated in human tumors. The members of this tumor master regulatory network are predicted to directly regulate the majority of the tumor specific gene expression profile. Similar to networks of master regulators that control organ development and cellular differentiation, there is a predicted high degree of co-regulation of target genes, and these network members are required in multiple eptihelia for tumor growth and invasiveness. We further found that Yki/Sd and bZIP/AP-1 factors, the downstream transcription factors of the Hippo and JNK pathways, initiate cellular reprogramming by activating several transcription factors of this network. Thus, modeling regulatory networks identified an ectopic yet highly ordered network of master regulators that control cancer cell specific gene expression.
