Affy_infection_medicago - Comparison of plant responses upon P. palmivora infection in wild type (A17) line and in the api mutant

ABSTRACT: affy_infection_medicago - api mutant has been shown to be more resistant to P. palmivora than the A17 wild type (WT) line. In this study, we want to compare both WT and mutant plant responses to the pathogen as well as their respective control transcriptomes in order to identify api-dependent gene networks. Following germination, A17 or api plants grown in vitro on Agar medium were inoculated (or not = controls) with a P. palmivora zoospores (10^5/ml) and harvested 16 hours after inoculation. Three independent repeats were performed.

affy_infection_medicago-Comparison of plant responses upon Aphanomyces euteiches infection in wild type (A17) line and in the Mtnf-ya1-1 mutant

Project description:affy_infection_medicago - affy_infection_medicago - MtNF-YA1 is a transcription factor involved in the regulation of nitrogen fixing nodule organogenesis. Mtnf-ya1-1 mutant has been shown to be more resistant to Aphanomyces euteiches (Ae), a root pathogen, than the A17 wild type (WT) line. In this study we want to compare both WT and mutant plant responses, 1 and 6 days post inoculation (dpi) between WT and the Mtnf-ya1-1 mutant, in order to identify MtNF-YA1-dependent gene networks during infection. Data about non inoculated A17 control plants and infected A17 at 1 dpi have been already obtained in another experiment in which the conditions of in vitro culture of M. truncatula plants and ofA.euteiches(Ae) inoculation were exactly the same than the ones used in these experiments.-Fifteen-day-old A17 or Mtnf-ya1-1 plants were grown in vitro on M medium. The entire roots were then inoculated (or not = controls) with a A. euteiches zoospores (105/ml) and harvested one or six days after inoculation. Three independent repeats were performed.

Comparison of plant responses upon Aphanomyces euteiches infection in wild type (A17) and NFP allelic mutants

Project description:affy_aphanomyces_medicago - NFP is one of the putative Nod factor receptor and plays therefore a key role in the establishment of symbiosis. nfp allelic mutants are more susceptible to Aphanomyces euteiches (Ae), a root pathogen, than the A17 wild type (WT) line. In this study we want to compare the early plant responses, 1 day post inoculation (dpi) between WT and the nfp2 mutant, in order to identify NFP-dependent gene networks during infection.-Fifteen-day-old A17 or nfp-2 plants were grown in vitro on M medium. The entire roots were then inoculated (or not = controls) with a A. euteiches zoospores (105/ml) and harvested one day after inoculation. Three independent repeats were performed.

Project description:affy_infection_medicago - affy_infection_medicago - HAP2a is a transcription factor involved in the regulation of nitrogen fixing nodule organogenesis. hap2a-1 mutant has been shown to be more resistant to Aphanomyces euteiches (Ae), a root pathogen, than the A17 wild type (WT) line. In this study we want to compare both WT and mutant plant responses, 1 and 6 days post inoculation (dpi) between WT and the hap2a-1 mutant, in order to identify HAP2a-dependent gene networks during infection.

affy_med_2011_10- Comparison of plant responses upon Aphanomyces euteiches infection in wild type (A17) line and in the lyr3-1 and lyr3-2 mutants

Project description:affy_med_2011_10 - affy_med_2011_10 - LYR3 encodes a lysin motif-receptor-like kinase (LysM-RLK) that consists of an extracellular ligand-binding domain composed of three LysM domains, a single transmembrane domain and a cytoplasmic serine/threonine kinase domain. A reverse genetic approach was undertaken to study the role of this gene in the pathosystem Medicago truncatula – Aphanomyces euteiches (Ae). Results suggest that lyr3-1 and lyr3-2 mutants are more susceptible to the root pathogen Aphanomyces euteiches than the A17 wild type (WT) line. In this study, we want to compare the early plant responses, 3 days post inoculation (dpi), between WT and the lyr3-1 and lyr3-2 mutants, in order to identify LYR3-dependent gene networks during infection.-Fourteen days old A17, lyr3-1 or lyr3-2 plants were grown in vitro on M medium. The entire roots were then inoculated (or not = controls) with A. euteiches zoospores (105/ml) and harvested three days after inoculation. Three independent repeats were performed.
