Publications for Plant Genome Duplication Database

PGDD citations


Genome wide identification of the auxin response factor gene family in Cicer arietinum

BMC Genomics
PMCID: 5921756
PMID: 29703137
DOI: 10.1186/s12864-018-4695-9

[…] alignment and phylogenetic tree construction were performed using MUSCLE and MEGA, respectively. Exon-intron distributions were analyzed using GSDS server. Gene duplications were determined using the PGDD database and the orthologous relationships were visualized using Circoletto. Amino acid content of the MR domain was calculated using the ‘Biostrings’ Bioconductor package. The putative cis-actin […]


Molecular Characterization, Evolution, and Expression Profiling of the Dirigent (DIR) Family Genes in Chinese White Pear (Pyrus bretschneideri)

Front Genet
PMCID: 5911567
PMID: 29713336
DOI: 10.3389/fgene.2018.00136

[…] Collinearity analysis was completed using Plant Genome Duplication Database (PGDD) () and circos software. […]


The Sequenced Angiosperm Genomes and Genome Databases

Front Plant Sci
PMCID: 5909171
PMID: 29706973
DOI: 10.3389/fpls.2018.00418

[…] third of all sequenced angiosperms are included by Phytozome, suggesting the presence of a major gap in the availability of most angiosperm genomes at Phytozome.The Plant Genome Duplication Database (PGDD) ( is a database currently hosting 43 angiosperm genomes, with tools to identify the intragenome and cross-genome synteny relationships. Synonymous substitutions […]


Duplication and diversification of lectin receptor like kinases (LecRLK) genes in soybean

Sci Rep
PMCID: 5897391
PMID: 29651041
DOI: 10.1038/s41598-018-24266-6

[…] n 200 kb,,. Furthermore, genes within a tandem duplication cluster should show a close relationship in a phylogenetic tree. The segmental duplicated GmLecRLK genes were characterized according to the plant genome duplication database (PGDD) ( The list of genes in duplicated genomic regions and Ka/Ks values of each gene pairs were retrieved from PGDD. The r […]


The mining and evolutionary investigation of AP2/ERF genes in pear (Pyrus)

BMC Plant Biol
PMCID: 5859658
PMID: 29558898
DOI: 10.1186/s12870-018-1265-x

[…] We used a method distinct from that used in the Genome Duplication Database (PGDD) ( [] to perform the synteny analysis. First, to identify the candidate homologous gene pairs (E < 1e-5, top 5 matches), a BLASTP alignment was carried ou […]


Genome wide analysis of the potato Hsp20 gene family: identification, genomic organization and expression profiles in response to heat stress

BMC Genomics
PMCID: 5774091
PMID: 29347912
DOI: 10.1186/s12864-018-4443-1

[…] in 100-kb chromosome fragment were considered as tandem duplicated genes []. The segmental duplicated genes of StHsp20 were identified by searching the segmental genome duplications of potato at the Plant Genome Duplication Database (PGDD, […]
