Strigolactone Levels in Dicot Roots Are Determined by an Ancestral Symbiosis Regulated Clade of the PHYTOENE SYNTHASE Gene Family

Front Plant Sci
PMCID: 5838088
PMID: 29545815
DOI: 10.3389/fpls.2018.00255

[…] Nucleotide and amino acid sequence analysis was done with the Geneious® software package version R7. The Medicago Gene Expression Atlas version 3.0 (MtGEA; ) was used through its web server. Entries for target genes were identified by BLAST searches or by searches for coexpressed genes. Tomato sequence information was obtained through the Solgenom […]


MtNRLK1, a CLAVATA1 like leucine rich repeat receptor like kinase upregulated during nodulation in Medicago truncatula

Sci Rep
PMCID: 5794917
PMID: 29391543
DOI: 10.1038/s41598-018-20359-4

[…] against the Mt4.0 database, John Craig Venter Institute [JCVI], For nine of the ten best hits, the expression pattern was available at the Medicago Gene Expression Atlas (MtGEA) ( and amongst these, only one gene (Medtr5g090100, M. truncatula genome v4.0), showed a nodulation-enhanced expression profile and was therefore designated MtNRLK1 (f […]


Pea Marker Database (PMD) – A new online database combining known pea (Pisum sativum L.) gene based markers

PLoS One
PMCID: 5658071
PMID: 29073280
DOI: 10.1371/journal.pone.0186713

[…] e markers included searching for homologous sequences in the M. truncatula genome and identifying the relevant entries (referred to as “Name matching” in ) in the M. truncatula Gene Expression Atlas (MtGEA) [,].The artificial LGs construction was performed using an original program developed within the frame of this study in Visual Basic for Applications []. Visualization of the database content w […]


Identification and Network Enabled Characterization of Auxin Response Factor Genes in Medicago truncatula

Front Plant Sci
PMCID: 5145899
PMID: 28018393
DOI: 10.3389/fpls.2016.01857

[…] To better understand the relationships within the MtARF gene family, a heatmap based on expression data for the 16 MtARF genes represented in the MtGEA was generated using Euclidean clustering (Figure ). Two major clades were apparent based solely on the expression profiles of these gene models across the 700+ experimental conditions of the atl […]


DELLA mediated gibberellin signalling regulates Nod factor signalling and rhizobial infection

Nat Commun
PMCID: 5025792
PMID: 27586842
DOI: 10.1038/ncomms12636

[…] Transcriptomic data were retrieved from the M. truncatula Gene Expression Atlas (MtGEA database,; ref. ), or from the SYMBIMICS website (; ref. ).For RT–qPCR experiments, total RNA was extracted from frozen roots u […]


A Snapshot of Functional Genetic Studies in Medicago truncatula

Front Plant Sci
PMCID: 4977297
PMID: 27555857
DOI: 10.3389/fpls.2016.01175

[…] and Zhang et al. (). Most of the data obtained from the Affymetrix GeneChip experiments have been stored and publicly shared on a dedicated webserver to provide a M. truncatula Gene Expression atlas (MtGEA,; He et al., ). Transcriptomics tools also comprise a high-throughput quantitative PCR platform to profile all known transcription factors used in studies such as Verdier et […]
