ABSTRACT: L. edodes strain w1 was cultured at 25°C in MYG medium (containing 1% malt extract, 0.1% peptone, 0.1% yeast extract, and 2% glucose). Fresh mycelium blocks were cultured in a 9cm petri dish containing MYG medium. After 8-day dark cul- ture, and they were divided into different treatment groups (group A,B,C,D,E). Group A was treated with 8mm-diameter L. edodes mycelium block on MYG medium for seven days and then treated at 37 °C for 30 min. 3. Group B was treated with 8mm-diameter L. edodes mycelium block on MYG medium for seven days and then treated at 4 °C for 60 min. Group C was treated with 8mm-diameter L. edodes mycelium block on MYG medium for seven days and then under 3500 lx light for 1 h. In group D, 8mm-diameter fresh L. edodes mycelium block were inoculated into MYG medium containing cadmium ions. In group E, 8mm-diameter L. edodes mycelium block was inoculated at 10 mm from the edge of the petri dish, and cultured at 25 ° C for 7 days. Afterwards, an activated 8-mm diameter tricho- derma mycelium block was inoculated at 1 cm from the edge of the petri dish at one end of the petri dish diameter (corresponding to the other end where L. edodes mycelium block was inoculated)
Project description:Our research describe the influence of aeration conditions in petri dishes for A. thaliana growth. We analyze the difference between plants grown in standard Petri dish (Non-aerated) and modified Petri dish that include aeration (Aerated). To characterize the differences between those conditions the gene expression analysis was performed. We also wanted to analyze the effect of using a micropore filter, so we designed another experiment with Aerated, Non-aerated and Micropore filter conditions.
Project description:Comparative transcriptome analysis of early interaction events in Scots pine root tissues following challenge with a pathogenic, saprophytic or symbiotic fungus. Seedlings of P. sylvestris (19 days post germination) were transferred to wet, sterile filter paper on Petri-plates. Thereafter, the roots of the seedlings were inoculated with the mycelial homogenate of either Heterobasidion annosum (FP5, P-type) a pathogenic root rot fungus which attacks Norway spruce, Scots pine and broad leaf trees or Laccaria bicolor, an obligate ectomycorrhizal symbiont or Trichoderma aureoviride- an obligate saprotroph. Thereafter, incubated for 30 minutes, during which time some hyphae adhered to the roots. The inoculated seedlings (ten) were then transferred to another wet sterile filter paper placed on 1% water agar in Petri dishes. A second set of moist sterile filter paper was laid over the roots. The region of the Petri-dish containing the roots was covered with aluminium foil and the edges of the plate sealed with parafilm. The seedlings were then incubated for 24 hr under a photoperiod of 16h light at 20 ºC. Control seedlings were ‘inoculated’ with sterile distilled water. Keywords: other
Project description:Circular agar plugs with fresh mycelium of H. annosum isolates were inoculated onto the center of 9-cm Petri plates containing 2% MEA (malt extract agar) and incubated at 22°C in the dark. Presence of viruses in H. annosum isolates used for the experiment: –1W, isogenic isolates fully cured of viral infections by thermal treatment lasting a one week; –A2, –A4, –A5, –C1, monohyphal cultures created by hyphal tipping; 2052–, isogenic isolates, which have received different combinations of viruses by horizontal transmission from a donor strain denoted by D; –3M, dual cultures maintained for three months.
Project description:4plex_physco_2014-05 - ppmax2 response to gr24 - How does the Ppmax2 moss mutant respond to Strigolactone (GR24)? - Two moss genotypes are used: WT and the Ppmax2 mutant. Moss tissues are fragmented, then plated on medium (Petri dish with cellophane disks) and cultivated for 3 weeks. Moss tissues are then transfered for 6 hours on acetone-containing medium (control treatment, for WT and Ppmax2) or GR24 (1 microM, in acetone)-containing medium (for Ppmax2). After 6 hours, the moss tissues are collected, quickly forzen in liquid nitrogen. RNA are isolated using the Quiagen RNeasy Plant mini kit (including a RNase-free DNase treatment on column). Two similar experiments (T1 and T2) have been led.
Project description:CTCs in cancer patients are thought to be responsible for metastasis. Currently, there is no ex vivo model that can isolate this group of cells. We have developed an ex vivo 4D lung cancer model that forms perfusable tumor nodules and form CTCs. Gene array analyses show 2504 differentially expressed genes when comparing CTCs from the 4D model seeded with A549 cells to the same cells grown on a petri dish (2D).

Project description:The softened green berries of Cabernet Sauvignon were cultured in a Petri dish. 0.3M sucrose solution with (±)-abscisic acid (ABA) and without (±)-ABA (control) were applied to the Petri dishes. The berry skins were sampled at 3 and 10 days after the application. PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Kazuya Koyama. The equivalent experiment is VV17 at PLEXdb.
Project description:Changes in gene expression in P. trichocarpa leaves was measured in response to growth competition by P. x canescens.Square petri dishes (12 x 12 cm) were filled autoclaved sand, 3 plantlets and Woody Plant Medium (WPM). In each petri dish we are growing 3 plantlets. As control 3 plantlets of P. trichocarpa and for the experiment a mixture of P. canescens and P. trichocarpa were P. trichocarpa is all the time the middle plantlet.

We compared the gene expression profile (Human OneArray v5 chip) of A549 cells, human lung cancer cell line, grown on petri dish (2D) and same cells circulating as tumor cells in our ex vivo model (4D/CTC).
