Inoculation of soybean (Glycine max) plants with Phakopsora pachyrhizi, the causal organism of Asian soybean rust, elicits a biphasic response characterized by a burst of differential gene expression in the first 12 h. A quiescent period occurs from 24 to 48 h after inoculation, in which P. pachyrhizi continues to develop but does not elicit strong host responses, followed by a second phase of intense gene expression. To correlate soybean responses with P. pachyrhizi growth and development, we i ...[more]

Project description:A large-scale parallel expression analysis was conducted to elucidate Mla-specified responses to powdery mildew infection using 22K Barley1 GeneChip probe arrays. Our goal was to identify genes differentially expressed in incompatible (resistant) vs. compatible (susceptible) and Mla-specified Rar1-dependent vs. -independent interactions. A split-split-plot design with 108 experimental units (3 replications x 2 isolates x 3 genotypes x 6 time points) was used to profile near-isogenic lines containing the Mla1, Mla6, and Mla13 resistance specificities in response to inoculation with the Blumeria graminis f. sp. hordei (Bgh) isolates 5874 (AvrMla1, AvrMla6) and K1 (AvrMla1, AvrMla13). ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Rico Caldo.

Project description:Time-course expression profiles of Bgh challenged barley cultivar C.I. 16151 (harboring the Mla6 powdery mildew resistance allele) and its fast-neutron-derived "Bgh-induced tip cell death1" mutant, bcd1, were compared using the 22K Barley1 GeneChip. Planting, stage of seedlings, harvesting, and experimental design were part of a larger experiment described by Caldo et al. (2004). PLEXdb BB4. Experiment Design: C.I. 16151 (wildtype) and bcd1 (mutant) were planted in separate 20 x 30-cm flats using sterilized potting soil. Each experimental flat consisted of six rows of 15 seedlings, with rows randomly assigned to one of six harvest time points (0, 8, 16, 20, 24, and 32 hai). Seedlings grown to the 1st leaf stage with 2nd leaf unfolded were inoculated with a high density of fresh conidiospores (84 +/- 19 spores/mm2). Groups of flats were placed at 18C (8-hour darkness, 16-hour light) in separate controlled growth chambers corresponding to the Bgh isolates. Rows of plants were harvested at each assigned time points and snap frozen in liquid nitrogen. The entire experiment was repeated three times in a standard split-split-plot design with 72 experimental units (2 genotypes x 2 pathogen isolates x 6 time points x 3 replications). Treatment Description: The samples constituted pairwise combinations of the the cultivar C.I. 16151(containing the Mla6 resistance allele), and its fast-neutron-derived "Bgh-induced tip cell death1" mutant, bcd1 with the two Bgh (Blumeria graminis f. sp. hordei) isolates, 5874 (AvrMla6, AvrMla1) and K1 (AvrMla13, AvrMla1). For each replication, individual genotypes were planted in separate 20 x 30 cm flats using sterilized potting soil. Each experimental flat consisted of six rows of 15 seedlings, with rows randomly assigned to one of six harvest times (0, 8, 16, 20, 24, and 32 hai). Seedlings were grown to the 2nd-leaf stage with 1st leaf unfolded, and inoculation was performed at 4 PM Central Standard Time by tipping the flats at 45oC and dusting the plants with a high density of fresh conidiospores [84 +/- 19 spores/mm2]. This procedure was repeated from the opposite angle to ensure that a high proportion of the cells are in contact with the fungus. This conidial density per unit leaf area routinely results in greater than 50% of epidermal cells that are successfully infected. Groups of flats were placed at 18oC (8 hours darkness, 16 hours light, 8 hours darkness) in separate controlled growth chambers corresponding to the Bgh isolate. Rows of plants were harvested at their assigned harvest times and flash-frozen in liquid nitrogen. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Roger P Wise.

Project description:TITLE: Transcriptional profiling of Rgene-mediated responses in rice PROJECT DESCRIPTION: The dominant gene Xa7 and the recessive gene xa5 of rice confer resistance to several races of the bacterial blight pathogen Xanthomonas oryzae pv. oryzae (Xoo). To reveal the modes of action and the defense responses these genes initiate, we decided to obtain the global transcriptional profiles of the rice cultivars IRBB7, IRBB5 (which harbor Xa7 and xa5, respectively) and IR24 undergoing early infection by the Xoo Race 2 strain PXO86. Both IRBB7 and IRBB5 are resistant to PXO86 (which carry the corresponding avirulence genes avrXa7 and avrxa5), whereas IR24 is susceptible. We inoculated by vacuum infiltration the three rice cultivars ten days after seed germination (or 2 weeks after sowing) and collected inoculated tissue at 5 different timepoints within the first day after inoculation. The transcriptional profiles obtained will provide valuable insight into the similarities and differences between incompatible interactions mediated by a dominant and a recessive Rgene, in comparison to a compatible interaction. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, David O Nino-Liu.

Project description:RESEARCH SUMMARY Bacterial blight and bacterial leaf streak, two of the most serious diseases of rice, are caused by Xanthomonas oryzae pathovar (pv.) oryzae (Xoo) and X. oryzae pv. oryzicola (Xoc) respectively. Xoo is a vascular pathogen that invades the xylem, whereas Xoc is non-vascular and colonizes the mesophyll apoplast. These distinctive types of infection represent the two most common ways plant pathogenic bacteria produce disease. As closely related pathogens of a model plant host, Xoo and Xoc constitute a powerful comparative system. We hypothesize that tissue-specific susceptibility to pathogenic bacteria can be explained partially by differential host responses during infection. To establish the global structure of susceptible responses to infection by Xoo and Xoc, we used the Affymetrix Rice Genome Array to analyze the abundance of transcripts in rice plants over four days after inoculation with virulent strains. MATERIAL AND METHODS - Plant Material: Oryza sativa ssp. japonica cv. Nipponbare plants were grown in pots containing LC-1 soil mixture, and arranged in flats of 20 pots, in growth chambers under a 12-h, 28ºC light and a 12-h, 25ºC dark cycle. To allow inversion of the flats for inoculation (modified dip-inoculation method, Niño-Liu et al, 2005, Journal of Phytopathology) seeds were sown through 1-cm perforations in a fibreglass tray resting on top of the pots. Peters Professional Fertilizer and iron chelate micronutrient were applied with watering every two days at rates of 0.25 and 4.5 g/L, respectively, until the day before inoculation. - Bacterial Strains and preparation of inoculum: Xoo strain PXO99A and Xoc strain BLS256 were used. For each, a single colony from a glucose yeast extract (GYE) agar plate was transferred to 5 ml of GYE liquid medium and incubated for 24 h at 28ºC with constant shaking at 250 rpm. Subsequently, 2 ml of this culture was transferred to 300 ml of fresh GYE liquid medium and incubated as above for an additional 18 h. Cells were pelleted by centrifugation at 4000 rpm. for 10 min, washed twice and resuspended in sterile 10 mm MgCl2 to an OD600 of 0.05, yielding 7 liters of inoculum. Tween-20 was added to a final concentration of 0.5%. - Modified dip-inoculation method: Fourteen days after sowing, and 2 h after the beginning of the light period, seedlings were inverted into inoculum, one flat each for Xoo, Xoc and Mock inoculum consisting of sterile 10 mM MgCl2 with 0.5% Tween-20, and vaccuum infiltrated at 500mm Hg for two minutes, two consecutive times, in a custom-made chamber. Following inoculation, plants were returned to the growth chamber. During growth, plants were cycled weekly in the same order through three growth chambers. In this way all plants could be incubated in the same final chamber following inoculation. For each replicate, position of the flats in the growth chamber (from left to right, used also for the order of inoculation and harvest) was determined by a split-plot design. - Timepoints, tissue collection: Within flats, assignment of pots for the harvest of inoculated tissue at 2, 4, 8, 24 and 96 h was made using a separate randomized complete block design. Tissue was harvested from plants in four pots (approximately 2g fresh weight) for each timepoint per inoculum per replication. Harvested tissue was immediately frozen in liquid nitrogen and stored at -80ºC until processing. - RNA isolation, purification, labeling, hybridizations, scanning: Total RNA was initially isolated from frozen whole plant tissue using the hot TRIzol reagent protocol for barley as described by Caldo et al (Plant Cell, 2004). The RNA was purified using Qiagen RNeasy spin columns, and adjusted to a final concentration of 1 ug/uL. Probe synthesis, labeling, and hybridization were performed at the Iowa State University GeneChip Core facility.

Project description:Transcriptional changes were monitored in the wheat cultivar Avocet*6/Yr1 following inoculation with avirulent and virulent wheat yellow rust (Puccinia striiformis f.sp. tritici) isolates using the Affymetrix wheat genome array GeneChip®. Seedlings of Avocet*6/Yr1 were grown to growth stage 12-13 (Zadoks et al., 1974) before inoculating with either the P.s. f.sp. tritici isolate 169E136 (Yr1-virulent) or 232E137 (Yr1-avirulent) or with talc for the Mock inoculation (Boyd and Minchin 2001). Plants were grown under a 16/8 hour photoperiod cycle, supplemented with sodium lighting (240 ?mol m-2 s-1) at day/night temperatures of 20°C/15°C and a relative humidity of 60%, both before and after inoculation, in a spore-free, containment level 2 greenhouse. Leaf samples from six seedlings were collected 6, 12, 24, 48 and 72 hpi for RNA extraction and transcriptomics analysis from three independent biological experiments. Leaf tissue was ground under liquid nitrogen and total RNA extracted using the TRIzol reagent method, following the manufacturer’s instructions (Invitrogen, Carlsbad, CA). RNA from each time point (16 ?g) were pooled to obtain 80 ?g of total RNA for each treatment (mock inoculated control; avirulent isolate inoculated; virulent isolate inoculated).

Project description:Transcriptional changes were monitored in the wheat cultivar Renan 24 hours post i noculation with adapted and non-adapted Magnaporthe isolates using the Affymetrix wheat genome array GeneChip®. Wheat plants cv. Renan were grown in a peat and sand (1:1) mix at 23 C in a Sanyo Fitotron growth cabinet (Sanyo Gallenkamp PLC, Loughborough, U.K.) with a 16/8 h, light/dark cycle. Three Magnaporthe isolates were used in this expt, two wheat-adapted isolates (BR32, BR37) and one wheat non-adapted isolate (BR29). Magnaporthe isolates were grown for eleven days on Complete Media Agar at 25 C under a 16/8h, light/dark cycle. Conidia were harvested by flooding the plates with 5 mL of sterile inoculation solution [0.25% (w/v) gelatine and 0.01% (v/v) Tween 20] and scraping the conidia from the surface using a sterile glass rod. Conidia were filtered through sterile miracloth and the density adjusted to 1 x 10 5 conidia mL-1 with inoculation solution. Fourteen day old wheat seedlings mist inoculated with 4 mL of a Magnaporthe conidia suspension and plants were sealed in plastic propagators to maintain relative humidity c.100% and kept at 25 C in the dark for the first 24 hours post inoculation (hpi). Inoculation solution without Magnaporthe conidia was used as a mock-inoculation control. Leaf samples were collected 24 hpi for transcriptomics analysis from three independent biological experiments. Leaf tissue was ground under liquid nitrogen and total RNA extracted using a QIAquick RNeasy Plant Extraction Kit (Qiagen, Hilden, Germany), followed by TURBO DNaseTM (Ambion, Texas, U.S.A.) treatment. RNeasy Mini Spin column purification (Qiagen) was used to further purify RNA samples for array hybridisation.
