Project description:This SuperSeries is composed of the following subset Series: GSE33636: Gene expression data from Medicago truncatula plantlet roots treated with symbiotic lipochitooligosaccharides (LCOs). GSE33637: Gene expression data from Medicago truncatula mutant plantlet roots treated with Myc-LCOs. Refer to individual Series
Project description:Publication title: Pseudonodule formation by wild type and symbiotic mutant Medicago truncatula in response to auxin transport inhibitors This SuperSeries is composed of the SubSeries listed below.
Project description:Rhizobium and allied bacteria form symbiotic nitrogen-fixing nodules on legume roots. Plant hormones appear to play a role in nodule formation. We treated Medicago truncatula roots with auxin transport inhibitors (ATIs) N-(1-naphthyl)phthalamic acid (NPA) and 2,3,5-triiodobenzoic acid (TIBA) to induce the formation of pseudonodules. We compared the transcriptional responses of M. truncatula roots treated with ATIs to roots inoculated with Sinorhizobium meliloti. The transcriptional response of M. truncatula roots 1 and 7 days after ATI treatment were opposite to roots treated with S. meliloti.

Three independent biological replicates were performed for each treatment (buffer, ATI and wild-type bacteria) at 21 days after treatment.
Project description:For transcript analysis of responses in Medicago truncatula to its symbiont Sinorhizobium meliloti wild type or the succinoglycan-deficient exoY mutant we compared transcripts from line A17 roots inoculated with 25 mL OD = 0.05 S. meliloti wild type or exoY mutant. Keywords: 1 line; 2 S. meliloti samples

Three independent biological replicates were performed at each time point (1 and 7 days after treatment) for each treatment (buffer and ATI).
