A transcript profile of Medicago truncatula 2HA tissue culture with auxin treatment

ABSTRACT: Leaf explants of the superembryogenic Medicago truncatula line 2HA were treated with auxin (1-naphthaleneacetic acid) for one week to induce the formation of roots (Imin et al J Exp Bot 58:439-451). Gene expression in the leaves and the NAA treated tissue cultures was compared to identify transcripts expressed during the commitment to root formation in tissue culture. We have used the Affymetrix Medicago Genome Array GeneChip to compared gene expression in Medicago truncatula leaves and leaf explants that have been cultured for one week on NAA, to identify genes expressed during the commitment to root formation in tissue culture. Keywords: Cell type comparison

A transcript profile of Medicago truncatula 2HA and Jemmalong during somatic embryogenesis

Project description:The Medicago truncatula line 2HA has a 500-fold greater capacity to regenerate plants in culture by somatic embryogenesis than wild-type Jemalong. We have compared transcriptomes of tissue cultures from leaf explants of these two lines. We have used the Affymetrix Medicago Genome Array GeneChip to compare leaf explants of Medicago truncatula Jemalong and the superembryogenic line 2HA after two weeks of tissue culture on 10 µM 1-naphthaleneacetic acid (NAA) and 4 µM 6-benzylaminopurine (BAP) (P4 10:4) Keywords: Genotype comparison

Vegetative and reproductive leaves - 12plex-medicago-2012-06_GENOPEA3.2

Project description:12plex_medicago-2012-06 - vegetative and reproductive leaves - Transcriptome in leaves of Medicago truncatula plants during the remobilization process . Effect of a nitrogen deficiency on this process.Note that lower leaves correspond to vegetative leaves (FV) and upper leaves correspond to leaves of the reproductive part (FR). - Analysis of expression in Medicago truncatula reproductive leaves in untreated and nitrogen deficient plants during remobilization process between beginning of flowering, pod filling and the end of pod filling.

Cell- and tissue-specific transcriptome analyses of Medicago truncatula root nodules

Project description:We used laser-capture microdissection (LCM) to isolate specific cells from the Medicago truncatula nodule meristem (M), the distal infection (DIZ), the proximal infection zone (PIZ), infected cells (IC) and uninfected cells (UIC) from the fixation zone. Based on Medicago GeneChips, we identified the cell- and tissue-specific programm of gene expression in Medicago truncatula root nodules.

Effects of Gongronella sp. w5 on Medicago truncatula transcriptome

Project description:To investigate the gene expression levels of Medicago truncatula roots after beneficial fungi Gongronella sp. w5 inoculated.Gongronella sp. w5 promoted M. truncatula growth and caused the accumulation of sucrose in M. truncatula root tissue at 16 day-post-inoculation (dpi) without invading into the root cells. The transport of photosynthetic product sucrose to the rhizosphere by M. truncatula root cells was accelerated by upregulating the SWEET gene.

microRNA profiling of root tissues and root forming explant cultures in Medicago truncatula

Project description:To identify key miRNAs involved in root meristem formation in M. truncatula, deep sequencing was used to compare the miRNA populations dreived from four tissues. These were; root tip tissue, containing the root apical meristem, elongation zone tissue, root forming callus tissue and non-root forming callus tissue. We identified 83 previously reported miRNAs, 24 new to M. truncatula, in 44 families. For the first time in M. truncatula, members of conserved miRNA families mir165, miR181 and miR397 were found. Bioinformatic analysis identified 38 potential novel miRNAs. Many miRNAs were differentially expressed between tissues, particularly RFC and NRFC. Examination and comparison of the microRNA population of four Medicago truncatula tissue types

Transcript profiling of hairy root lines overexpressing MtPAR

Project description:Hairy root lines over-expressing MtPAR using a 35S promoter compared with hairy lines over-expressing GUS gene. Hairy roots were generated in vitro using leaf explants from Medicago A17. The goal of this experiment is to prove that ectopic expression expression of MtPAR is sufficient to induce tannin biosynthesis

Analysis of gene expression in leaves of Medicago truncatula plants inoculated with arbuscular mycorrhizal fungi and plants fertilized with phosphate

Project description:Arbuscular mycorrhizas (AM) are the most common symbiotic associations between plant’s root compartment and fungi. They can provide both nutritional benefit (mostly inorganic phosphate) leading to improved growth and non-nutritional benefits including defense responses to environmental cues throughout the host plant, which in return delivers carbohydrates to the symbiont. However how transcriptional changes occurring in AM leaves differ from those induced by phosphate fertilization is poorly understood. We investigated systemic changes in the leaves of mycorrhized Medicago truncatula compared to non-mycorrhized control plants, and in phosphate fertilized plants compared to control plants.
