In this study, we identified the putative regulatory genes in an albino mutant of Bambusa oldhamii using comparative physiology and transcriptome analysis. The degeneration of chloroplasts, low chlorophyll (Chl) content and reduced photosynthetic capacity were observed in albinotic B. oldhamii compared to normal lines. A total of 6191 unigenes were identified that were clearly differentially expressed between albino and normal lines by transcriptome sequencing. Most genes related to chloroplast development (such as Psa, Psb) and pigment biosynthesis (such as LHC, GUN4, ZEP) were downregulated significantly in albinotic lines, which might be responsible for the albino phenotype. Moreover, some transcription factors (TFs) such as PIF and GLK1 were identified to be involved in chloroplast development and Chl synthesis, indicating the involvement of putative regulatory pathways PIF-LHC and GLK1-LHC\/Psa\/Psb in albinotic B. oldhamii. Finally, the downregulation of some stress responsive TFs (like ICE1 and EREB1) suggested a reduction in stress resistance of albinotic B. oldhamii. The above findings provided new insights into the molecular mechanism of albinism in bamboo.<\/jats:p>","DOI":"10.3390\/plants12244090","type":"journal-article","created":{"date-parts":[[2023,12,6]],"date-time":"2023-12-06T11:32:29Z","timestamp":1701862349000},"page":"4090","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Comparative Physiology and Transcriptome Analysis Provides Insights into the Regulatory Mechanism of Albinotic Bambusa oldhamii"],"prefix":"10.3390","volume":"12","author":[{"given":"Qixia","family":"Qian","sequence":"first","affiliation":[{"name":"College of Landscape Architecture, Zhejiang A&F University, Lin\u2019An 311300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Quanfeng","family":"Ye","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Subtropical Silviculture, Zhejiang A&F University, Lin\u2019An 311300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yin","family":"Xu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Subtropical Silviculture, Zhejiang A&F University, Lin\u2019An 311300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naresh","family":"Vasupalli","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Subtropical Silviculture, Zhejiang A&F University, Lin\u2019An 311300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haiwen","family":"Lu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Subtropical Silviculture, Zhejiang A&F University, Lin\u2019An 311300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiutao","family":"Hu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Subtropical Silviculture, Zhejiang A&F University, Lin\u2019An 311300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5092-6950","authenticated-orcid":false,"given":"Dan","family":"Hou","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Subtropical Silviculture, Zhejiang A&F University, Lin\u2019An 311300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11827","DOI":"10.4238\/2015.October.2.16","article-title":"Identification of Genes Involved in Spontaneous Leaf Color Variation in Pseudosasa japonica","volume":"14","author":"Yang","year":"2015","journal-title":"Genet.
