NAC transcription factors comprise of a large gene family represented by more than 100 members in <jats:italic>Arabidopsis</jats:italic>, rice and soybean etc. Recently, a preliminary phylogenetic analysis was reported for NAC gene family from 11 plant species. However, no comprehensive study incorporating phylogeny, chromosomal location, gene structure, conserved motifs, and expression profiling analysis has been presented thus far for the model tree species <jats:italic>Populus</jats:italic>.</jats:p>\n          </jats:sec>\n          <jats:sec>\n            <jats:title>Results</jats:title>\n            <jats:p>In the present study, a comprehensive analysis of NAC gene family in <jats:italic>Populus</jats:italic> was performed. A total of 163 full-length NAC genes were identified in <jats:italic>Populus</jats:italic>, and they were phylogeneticly clustered into 18 distinct subfamilies. The gene structure and motif compositions were considerably conserved among the subfamilies. The distributions of 120 <jats:italic>Populus</jats:italic> NAC genes were non-random across the 19 linkage groups (LGs), and 87 genes (73%) were preferentially retained duplicates that located in both duplicated regions. The majority of NACs showed specific temporal and spatial expression patterns based on EST frequency and microarray data analyses. However, the expression patterns of a majority of duplicate genes were partially redundant, suggesting the occurrence of subfunctionalization during subsequent evolutionary process. Furthermore, quantitative real-time RT-PCR (RT-qPCR) was performed to confirm the tissue-specific expression patterns of 25 NAC genes.</jats:p>\n          </jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion</jats:title>\n            <jats:p>Based on the genomic organizations, we can conclude that segmental duplications contribute significantly to the expansion of <jats:italic>Populus</jats:italic> NAC gene family. The comprehensive expression profiles analysis provides first insights into the functional divergence among members in NAC gene family. In addition, the high divergence rate of expression patterns after segmental duplications indicates that NAC genes in <jats:italic>Populus</jats:italic> are likewise to have been retained by substantial subfunctionalization. Taken together, our results presented here would be helpful in laying the foundation for functional characterization of NAC gene family and further gaining an understanding of the structure-function relationship between these family members.</jats:p>\n          </jats:sec>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699994110388352","@type":"Researcher","foaf:name":[{"@value":"Ruibo Hu"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699994110388354","@type":"Researcher","foaf:name":[{"@value":"Guang Qi"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699994110388353","@type":"Researcher","foaf:name":[{"@value":"Yingzhen Kong"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699994110388356","@type":"Researcher","foaf:name":[{"@value":"Dejing Kong"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699994110388357","@type":"Researcher","foaf:name":[{"@value":"Qian Gao"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699994110388355","@type":"Researcher","foaf:name":[{"@value":"Gongke Zhou"}]}],"publication":{"publicationIdentifier":[{"@type":"EISSN","@value":"14712229"}],"prism:publicationName":[{"@value":"BMC Plant Biology"}],"dc:publisher":[{"@value":"Springer Science and Business Media LLC"}],"prism:publicationDate":"2010-07-15","prism:volume":"10","prism:number":"1","prism:startingPage":"145"},"reviewed":"false","url":[{"@id":"https://link.springer.com/content/pdf/10.1186/1471-2229-10-145.pdf"}],"createdAt":"2012-05-01","modifiedAt":"2021-09-01","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360004234643996672","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Evolution of plant conducting cells: perspectives from key regulators of vascular cell differentiation"}]},{"@id":"https://cir.nii.ac.jp/crid/1360285710566908032","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"A NAC domain protein family contributing to the regulation of wood formation in poplar"}]},{"@id":"https://cir.nii.ac.jp/crid/1360567184719351552","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Populus NST/SND orthologs are key regulators of secondary cell wall formation in wood fibers, phloem fibers and xylem ray parenchyma cells"}]},{"@id":"https://cir.nii.ac.jp/crid/1360846645591549440","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"NAC-MYB-based transcriptional regulation of secondary cell wall biosynthesis in land plants"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282679304226176","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Arabidopsis NAC domain proteins VND-INTERACTING1 and ANAC103 interact with multiple NAC domain proteins"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282763108287104","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Evolution of Conducting Cells in Plants; a Perspective from Key Transcription Factors of Conducting Cell Differentiation: From Recent Studies on Master Regulatory Transcription Factors for the Differentiation of Tracheary Elements and Sieve Element"},{"@language":"ja","@value":"植物の通道細胞進化を転写因子から読み解く"},{"@value":"植物の通道細胞進化を転写因子から読み解く : 道管要素と師部要素の分化を制御するマスター転写因子の研究から"},{"@language":"ja-Kana","@value":"ショクブツ ノ ツウドウ サイボウ シンカ オ テンシャ インシ カラ ヨミ トク : ドウカン ヨウソ ト シブ ヨウソ ノ ブンカ オ セイギョ スル マスター テンシャ インシ ノ ケンキュウ カラ"}]},{"@id":"https://cir.nii.ac.jp/crid/1390577818149360768","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Effects of <i>SpsNAC042</i> transgenic <i>Populus hopeiensis</i> on root development, leaf morphology and stress resistance"},{"@value":"Effects of SpsNAC042 transgenic Populus hopeiensis on root development, leaf morphology and stress resistance"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1186/1471-2229-10-145"},{"@type":"CROSSREF","@value":"10.1093/jxb/erw473_references_DOI_5GayCmcIYenuJMA97u7KN8dw9Qz"},{"@type":"CROSSREF","@value":"10.1111/j.1365-313x.2011.04614.x_references_DOI_5GayCmcIYenuJMA97u7KN8dw9Qz"},{"@type":"CROSSREF","@value":"10.1271/kagakutoseibutsu.56.353_references_DOI_5GayCmcIYenuJMA97u7KN8dw9Qz"},{"@type":"CROSSREF","@value":"10.1093/treephys/tpz004_references_DOI_5GayCmcIYenuJMA97u7KN8dw9Qz"},{"@type":"CROSSREF","@value":"10.3389/fpls.2015.00288_references_DOI_5GayCmcIYenuJMA97u7KN8dw9Qz"},{"@type":"CROSSREF","@value":"10.1270/jsbbs.22079_references_DOI_5GayCmcIYenuJMA97u7KN8dw9Qz"},{"@type":"CROSSREF","@value":"10.5511/plantbiotechnology.15.0208a_references_DOI_5GayCmcIYenuJMA97u7KN8dw9Qz"}]}
