Synthesis of very-long-chain fatty acids in the epidermis controls plant organ growth by restricting cell proliferation.

Nobusawa Takashi T Okushima Yoko Y Nagata Noriko N Kojima Mikiko M Sakakibara Hitoshi H Umeda Masaaki M

PLoS biology 20130409 4

Plant organ growth is controlled by inter-cell-layer communication, which thus determines the overall size of the organism. The epidermal layer interfaces with the environment and participates in both driving and restricting growth via inter-cell-layer communication. However, it remains unknown whether the epidermis can send signals to internal tissue to limit cell proliferation in determinate growth. Very-long-chain fatty acids (VLCFAs) are synthesized in the epidermis and used in the formation ...[more]

Arabidopsis microRNA Organ Map

Project description:This experiment was designed to determine the presence and levels of microRNAs and other select small RNAs in the major organs of wild-type (Col-0) Arabidopsis thaliana grown under standard conditions. To obtain a global overview of miRNA levels in wild-type Arabidopsis, a tissue expression map was generated. Two samples of total RNA from siliques, stems, cauline leaves, roots, short-day seedlings, long-day seedlings, and rosette leaves as well as four samples from inflorescences were obtained. All duplicate samples were harvested from independent crops of plants grown under the same conditions, and thus represent biologcial replicates. Hybridizations were always comparing a given sample against a common, synthetic reference set. 225 reference DNA oligos comprising the sense strand of each RNA represented on the array flanked by constant 5' and 3' sequences representing the adapters used in RNA cloning (Axtell and Bartel). Amplification and Cy5 end-labeling of this synthetic set of oligos provides a constant reference signal that allows comparison of different Cy3-labeled biological samples.

Transcription profiling of Zea mays embryos under camptothecin (CPT) treatment.

Project description:Camptothecin (CPT) is a plant alkaloid that specifically binds topoisomerase I (Topo I) inhibiting its activity and inducing double stranded breaks in the DNA, activating the genotoxic cell responses, and ultimately, it might trigger programmed cell death (PCD). We used microarrays to detail the changes in gene expression during as a consequence of CPT treatment in maize immature embryos. In four independent experiments immature embryos were plated on MS medium supplemented with 50 uM CPT and incubated during three days. Untreated embryos incubated on MS medium were used as controls.

Transcription profiling of Arabidopsis dms4-1, drd1-1 and drd1-6 mutant seedlings against wild-type to identify targets of IWR1-like transcription factor

Project description:We identified in a forward genetic screen a novel factor required for RNA-directed DNA methylation (IWR1-like transcription factor). The aim of the study was to identify natural targets of this factor and to compare it to targets of drd1 another major key factor required for the RNA silencing process in plants. We performed transcriptome analysis to identify targets of this factor. For this we used whole plants at seedling stage, isolated total RNA and then used the standard Affymetrix pipeline/chemistry. The mutated transcription factor, dms4-1 was compared to its respective wildtype (EDT, Col-O background). For microarray analysis THREE biological replicates were run. For transcriptome comparison we analyzed another factor required for the process RNA-directed DNA methylation in plants, drd1 also identified in a forward genetic screen and previously characterized in depth (Kanno et al. Current Biology, 14, 801-805, (2004), Huettel et al. EMBO J. 25, 2828-2836 (2006)). For transcriptome analysis two alleles of drd1 (drd1-1 and drd1-6) with two biological replicates each was compared to the respective wildtype DT, which served as starting material in this forward genetic screen (DT, Col-0 background). For drd1 mutants and DT wildtype analysis 10 day old seedlings were used as starting matieral while for dms4-1 and EDT 3 week old seedlings were analyzed.
