Penetration resistance: Wildtype and ataf1-1 mutant response to Bgh 12 h after inoculation, 2*2 factorial design

ABSTRACT: Arabidopsis is a non-host to the biotrophic fungus Blumeria graminis f.sp. hordei (Bgh), effectively hindering Bgh ingress to the epidermal cells by deposition of callosic papillae formations, i.e. penetration resistance. To better understand the transcriptional changes in Arabidopsis towards Bgh, we compared un-inoculated and inoculated wild-type Arabidopsis samples, with those an ATAF1 mutant allele, compromised in penetration resistance. The experiment included sampling of 8 rosettes for each replicate sample from 6-weeks old plants, 12 hrs after inoculation. A total of 12 biolocigal replicates were sampled with three replicates from each of the four blocks (Wild-type, ataf1-1, Bgh, control). ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Michael Krogh Jensen.

Transcription profiling of Arabidopsis eds1 mutant and NahG transgenics infection penetration success by the barley powdery mildew Blumeria graminis f. sp. hordei Bgh

Project description:Arabidopsis does not support the growth and asexual reproduction of the barley pathogen, Blumeria graminis f. sp. hordei Bgh). A majority of germlings fail to penetrate the epidermal cell wall and papillae. To gain additional insight into this interaction, we determined whether the salicylic acid (SA) or jasmonate (JA)/ethylene (ET) defence pathways played a role in blocking barley powdery mildew infections. Only the eds1 mutant and NahG transgenics supported a modest increase in penetration success by the barley powdery mildew. We also compared the global gene expression patterns of Arabidopsis inoculated with the non-host barley powdery mildew to those inoculated with a virulent, host powdery mildew, Erysiphe cichoracearum. Genes repressed by inoculations with non-host and host powdery mildews relative to non-inoculated control plants accounted for two-thirds of the differentially expressed genes. A majority of these genes encoded components of photosynthesis and general metabolism. Consistent with this observation, Arabidopsis growth was inhibited following inoculation with Bgh, suggesting a shift in resource allocation from growth to defence. A number of defence-associated genes were induced during both interactions. These genes likely are components of basal defence responses, which do not effectively block host powdery mildew infections. In addition, genes encoding defensins, anti-microbial peptides whose expression is under the control of the JA/ET signalling pathway, were induced exclusively by non-host pathogens. Ectopic activation of JA/ET signalling protected Arabidopsis against two biotrophic host pathogens. Taken together, these data suggest that biotrophic host pathogens must either suppress or fail to elicit the JA/ET signal transduction pathway.

Transcription profiling of barley plants containing variants of Mla1 and Mla6 powdery mildew resistance genes

Project description:A split-split-plot design with 144 experimental units (3 replications x 4 genotypes x 6 time points x 2 treatment types) was used to profile barley plants containing variants of Mla1 and Mla6 powdery mildew resistance genes in response to inoculation with the Blumeria graminis f. sp. hordei (Bgh) isolates 5874 (AvrMla1, AvrMla6). Barley leaves were harvested from inoculated and non-inoculated plants at 6 time points (0,8,16,20,24 and 32 hrs) after Bgh inoculation. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Rico Caldo.

Blumeria graminis fsp hordei effects on translation initiation in compatible and incompatible barley

Project description:The goal of this experiment was to examine the effects of Blumeria gramins f. sp. hordei (Bgh) on the host process of translation initiation in both incompatible and compatible interactions with Hordeum vulgare. This was done by using Bgh isolate 5874 (AVRa6) on the resistant host CI 16151 (Mla6) and fast-neutron derived, loss-of-function mutant m9472 (mla6). Plants were grown 7 days in the greenhouse and then inoculated or non-inoculated and transferred to an 18°C growth chamber with an 8 hr dark, 16 hr light photoperiod. At 32 hours after infection the tissue was harvested and immediately frozen in liquid nitrogen. From the same tissue, total RNA was isolated using a Trizol method, while polysomal RNA was isolated by sucrose density centrifugation. Three biological replications were conducted. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Jackson Moeller.

Genetic regulation of barley gene expression in response to the powdery mildew fungus, Blumeria graminis f. sp. hordei (Bgh)

Project description:Expression analysis was performed on total RNA from the Q21861 and SM89010 barley lines, and 75 derived doubled haploid progeny, with CI 16137 included as an internal Mla1 allele control. Samples were blocked by time-point and completely randomized within each block. For each sample, seven day old seedlings were inoculated with Blumeria graminis f. sp. hordei (Bgh) isolate 5874 (AVRa1, AVRa6, AVRa12), and first leaves were collected at 16 and 32 hours after inoculation (HAI). ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Roger Wise.

Transcription profiling of wild type and mutant Arabidopsis plants innoculated with the host powdery mildew Erysiphe cichoracearum or the non-host barley powdery mildew Blumeria graminis f. sp. hordei

Project description:Attack by the host powdery mildew Erysiphe cichoracearum usually results in successful penetration and rapid proliferation of the fungus on Arabidopsis. By contrast, the nonhost barley powdery mildew Blumeria graminis f. sp. hordei (Bgh) typically fails to penetrate Arabidopsis epidermal cells. In both instances the plant secretes cell wall appositions or papillae beneath the penetration peg of the fungus. Genetic screens for mutations that result in increased penetration of Bgh on Arabidopsis have recently identified the PEN1 syntaxin. Here we examine the role of PEN1 and of its closest homologue, SYP122, identified as a syntaxin whose expression is responsive to infection. pen1 syp122 double mutants are both dwarfed and necrotic, suggesting that the two syntaxins have overlapping functions. Although syp122-1 and the cell wall mur mutants have considerably more pronounced primary cell wall defects than pen1 mutants, these have relatively subtle or no effects on penetration resistance. Upon fungal attack, PEN1 appears to be actively recruited to papillae, and there is a 2-h delay in papillae formation in the pen1-1 mutant. We conclude that SYP122 may have a general function in secretion, including a role in cell wall deposition. By contrast, PEN1 appears to have a basal function in secretion and a specialized defense-related function, being required for the polarized secretion events that give rise to papilla formation.
