In plants, a large number of 21- or 24-nucleotide (nt) phased small interfering RNAs (phasiRNAs) are produced via processing of long RNA precursors by Dicer-like proteins. However, the roles of phasiRNAs remain largely unknown. The development of imaging technology and RNA profiling has clarified the spatiotemporal regulation of phasiRNAs, and subsequently the different functions of 21-nt trans-acting phasiRNAs and 24-nt cis-regulatory phasiRNAs during male organ development. This review focuses on the biogenesis, diversification, spatiotemporal expression pattern and function of phasiRNAs in plants.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Komiya</LastName><ForeName>Reina</ForeName><Initials>R</Initials><AffiliationInfo><Affiliation>Science and Technology Group, Okinawa Institute of Science and Technology Graduate University (OIST).</Affiliation></AffiliationInfo><AffiliationInfo><Affiliation>PRESTO, Japan Science and Technology Agency (JST).</Affiliation></AffiliationInfo></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType><PublicationType UI="D016454">Review</PublicationType></PublicationTypeList><ArticleDate DateType="Electronic"><Year>2021</Year><Month>11</Month><Day>11</Day></ArticleDate></Article><MedlineJournalInfo><Country>Japan</Country><MedlineTA>Genes Genet Syst</MedlineTA><NlmUniqueID>9607822</NlmUniqueID><ISSNLinking>1341-7568</ISSNLinking></MedlineJournalInfo><ChemicalList><Chemical><RegistryNumber>0</RegistryNumber><NameOfSubstance UI="D035683">MicroRNAs</NameOfSubstance></Chemical><Chemical><RegistryNumber>0</RegistryNumber><NameOfSubstance UI="D018749">RNA, Plant</NameOfSubstance></Chemical><Chemical><RegistryNumber>0</RegistryNumber><NameOfSubstance UI="D034741">RNA, Small Interfering</NameOfSubstance></Chemical></ChemicalList><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName UI="D018506" MajorTopicYN="Y">Gene Expression Regulation, Plant</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D035683" MajorTopicYN="Y">MicroRNAs</DescriptorName><QualifierName UI="Q000235" MajorTopicYN="N">genetics</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D010944" MajorTopicYN="N">Plants</DescriptorName><QualifierName UI="Q000235" MajorTopicYN="N">genetics</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D018749" MajorTopicYN="N">RNA, Plant</DescriptorName><QualifierName UI="Q000235" MajorTopicYN="N">genetics</QualifierName><QualifierName UI="Q000378" MajorTopicYN="N">metabolism</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D034741" MajorTopicYN="N">RNA, Small Interfering</DescriptorName><QualifierName UI="Q000235" MajorTopicYN="N">genetics</QualifierName><QualifierName UI="Q000378" MajorTopicYN="N">metabolism</QualifierName></MeshHeading></MeshHeadingList><KeywordList Owner="NOTNLM"><Keyword MajorTopicYN="N">Argonaute</Keyword><Keyword MajorTopicYN="N">microRNA</Keyword><Keyword MajorTopicYN="N">phasiRNA</Keyword><Keyword MajorTopicYN="N">plants</Keyword><Keyword MajorTopicYN="N">reproduction</Keyword></KeywordList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="pubmed"><Year>2021</Year><Month>11</Month><Day>12</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2022</Year><Month>2</Month><Day>26</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>2021</Year><Month>11</Month><Day>11</Day><Hour>6</Hour><Minute>35</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pubmed">34759068</ArticleId><ArticleId IdType="doi">10.1266/ggs.21-00042</ArticleId></ArticleIdList></PubmedData></PubmedArticle></PubmedArticleSet>
