Transcriptional profiling of Medicago truncatula during Erysiphe pisi infection
Resistance to powdery mildew has been studied in a number of plant species, yet the molecular mechanisms remain largely unknown. Transcription factors (TFs) play a critical role in the plant defense response by regulating the transcriptional machinery which coordinates the expression of a large group of genes involved in plant defense. Using high-throughput quantitative real-time PCR (qPCR) tec...
متن کاملMolecular and cytological responses of Medicago truncatula to Erysiphe pisi.
SUMMARY Powdery mildew is an economically important disease in a number of crop legumes; however, little is known about resistance to the disease in these species. To gain a better understanding of the genetics of resistance and plant responses to powdery mildew in legumes, we developed a pathosystem with Medicago truncatula and Erysiphe pisi. Screening accessions of M. truncatula identified ge...
متن کاملAccumulation of potentiometric and other dyes in haustoria of Erysiphe graminis in living host cells
Twenty-five vital fluorescent dyes were tested for accumulation in haustoria of Erysiphe graminis (DC) Merat f. sp. hordei Em . Marchai when applied to coleoptile epidermal host cells of Hordeum vulgare L . Eight of the dyes gave fluorescence to structures judged to be haustorial mitochondria . The potentiometric cyanine dyes, DiOC4 (3) and DiOC 7 (3) gave best differentiation between the putat...
متن کاملWater Soluble Antifungal Metabolites of Pea (pisum Sativum) Leaves Determine Infection by Erysiphe Pisi
Antifungal activity of water soluble exudates of pea leaves was assayed. Exudates of different nodal leaves were collected by dipping them in sterilized distilled water for different length of time and conidial germination of four non-pathogenic to pea fungi (Alternaria solani, Curvularia lunata, Helminthosporium penniseti and H. echinocloa) and one pea pathogenic to pea fungus (Erysiphe pisi) ...
متن کاملPseudomonas fluorescens and Trichoderma asperellum Enhance Expression of Gα Subunits of the Pea Heterotrimeric G-protein during Erysiphe pisi Infection
We investigated the transcript accumulation patterns of all three subunits of heterotrimeric G-proteins (Gα1 and 2, Gβ, and Gγ) in pea under stimulation of two soil-inhabiting rhizosphere microbes Pseudomonas fluorescens OKC and Trichoderma asperellum T42. The microbes were either applied individually or co-inoculated and the transcript accumulation patterns were also investigated after challen...
