However, there is limited information available about the specific functions of SAURs in rice due to the presence of extensive redundant genes. In this study, we found that OsSAUR10 contains a conserved downstream element in its 3\u2032 untranslated region that causes its transcripts to be unstable, ultimately leading to the immediate degradation of the mRNA in rice. In our investigation, we discovered that OsSAUR10 is located in the plasma membrane, and its expression is regulated in a tissue-specific, developmental, and hormone-dependent manner. Additionally, we created ossaur10 mutants using the CRISPR\/Cas9 method, which resulted in various developmental defects such as dwarfism, narrow internodes, reduced tillers, and lower yield. Moreover, histological observation comparing wild-type and two ossaur10 mutants revealed that OsSAUR10 was responsible for cell elongation. However, overexpression of OsSAUR10 resulted in similar phenotypes to the wild-type. Our research also indicated that OsSAUR10 plays a role in regulating the expression of two groups of genes involved in auxin biosynthesis (OsYUCCAs) and auxin polar transport (OsPINs) in rice. Thus, our findings suggest that OsSAUR10 acts as a positive plant growth regulator by contributing to auxin biosynthesis and polar transport.<\/jats:p>","DOI":"10.3390\/plants12223880","type":"journal-article","created":{"date-parts":[[2023,11,17]],"date-time":"2023-11-17T00:49:47Z","timestamp":1700182187000},"page":"3880","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["The Small Auxin-Up RNA SAUR10 Is Involved in the Promotion of Seedling Growth in Rice"],"prefix":"10.3390","volume":"12","author":[{"given":"Xiaolong","family":"Huang","sequence":"first","affiliation":[{"name":"School of Life Sciences, Guizhou Normal University, Guiyang 550001, China"},{"name":"Key Laboratory of Plant Physiology and Development Regulation, Guizhou Normal University, Guiyang 550001, China"},{"name":"Laboratory of State Forestry Administration on Biodiversity Conservation in Mountainous Karst Area of Southwestern China, Guizhou Normal University, Guiyang 550001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhanhua","family":"Lu","sequence":"additional","affiliation":[{"name":"Rice Research Institute, Guangdong Academy of Agricultural Sciences, Guangzhou 510640, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisheng","family":"Zhai","sequence":"additional","affiliation":[{"name":"School of Life Sciences, Guizhou Normal University, Guiyang 550001, China"},{"name":"Key Laboratory of Plant Physiology and Development Regulation, Guizhou Normal University, Guiyang 550001, China"},{"name":"Laboratory of State Forestry Administration on Biodiversity Conservation in Mountainous Karst Area of Southwestern China, Guizhou Normal University, Guiyang 550001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Na","family":"Li","sequence":"additional","affiliation":[{"name":"School of Life Sciences, Guizhou Normal University, Guiyang 550001, China"},{"name":"Key Laboratory of Plant Physiology and Development Regulation, Guizhou Normal University, Guiyang 550001, China"},{"name":"Laboratory of State Forestry Administration on Biodiversity Conservation in Mountainous Karst Area of Southwestern China, Guizhou Normal University, Guiyang 550001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huiqing","family":"Yan","sequence":"additional","affiliation":[{"name":"School of Life Sciences, Guizhou Normal University, Guiyang 550001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"17","DOI":"10.1093\/jxb\/ery332","article-title":"The SAUR gene family: The plant\u2019s toolbox for adaptation of growth and development","volume":"70","author":"Stortenbeker","year":"2019","journal-title":"J.
