Map-based cloning analyses of a natural semi-dwarf rice mutant with inwardly curled leaves found in the field revealed that the defects were due to a mutation of a SHAQKYF-class MYB family transcription factor, OsKANADI1 (OsKAN1). OsKAN1 directly bound to the OsYABBY5 (OsYAB5) promoter to repress its expression and interacted with OsYAB5 to form a functional OsKAN1-OsYAB5 complex. GIBERELLIN 2-OXIDASE6 (OsGA2ox6), encoding an enzyme in the gibberellin (GA) catabolic pathway, was activated by OsYAB5. Furthermore, the OsKAN1-OsYAB5 complex suppressed the inhibitory effect of OsKAN1 toward OsYAB5 and inhibited OsYAB5-induced OsGA2ox6 expression. The proOsKAN1:OsYAB5 transgenic plants were taller than wild-type plants, whereas oskan1 proOsKAN1:OsYAB5 plants exhibited a severe dwarf phenotype due to the absence of the OsKAN1-OsYAB5 complex. The OsKAN1-OsYAB5 complex modulated OsGA2ox6 expression, thereby regulating the levels of bioactive gibberellins and, consequently, plant height. This study elucidated the mechanism underlying the effect of the OsKAN1-OsYAB5-OsGA2ox6 regulatory pathway on plant height at different positions in rice stems and provided insights on stem development and candidate genes for the aerial architecture improvement of crop plants.","PeriodicalId":20186,"journal":{"name":"Plant Cell","volume":" ","pages":""},"PeriodicalIF":10.0,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11663581/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142392432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we performed a systematic coexpression analysis of hetACCase and its regulators in Arabidopsis (Arabidopsis thaliana) to better understand the regulatory mechanism of hetACCase. Our analysis uncovered REGULATOR OF FATTY ACID SYNTHESIS 1 (RFS1), whose expression is positively correlated with that of other regulators of hetACCase. The RFS gene family encodes two plastid inner envelope membrane proteins with undiscovered roles. Further analysis revealed that RFS1 colocalizes and directly interacts with CARBOXYLTRANSFERASE INTERACTOR 1 (CTI1). CRISPR/Cas9-mediated knockouts of RFSs exhibit enhanced hetACCase activity, higher FAS rates, and increased fatty acid contents, with particularly marked accumulation of absolute triacylglycerol levels in leaves, similar to cti mutants. The mutations of rfs and cti alter the plastid membrane distribution pattern of α-CT, leading to reduced hetACCase activity on the membrane, which could potentially be the original mechanism through which RFSs restrain hetACCase activity. Thus, we reveal a unique regulatory module that regulates de novo FAS and a genetic locus that may contribute to breeding of improved oil crops.","PeriodicalId":20186,"journal":{"name":"Plant Cell","volume":" ","pages":""},"PeriodicalIF":10.0,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11663567/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142569414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, how they cooperate to regulate transcription in plants remains largely unclear. Our study revealed that GLOBAL TRANSCRIPTION FACTOR GROUP E 4 (GTE4) binds to acetylated histones and forms a complex with the functionally redundant H3K4me3-binding EMSY-like proteins EML1 or EML2 (EML1/2) in Arabidopsis thaliana. The eml1 eml2 (eml1/2) double mutant exhibits a similar morphological phenotype to gte4, and most of the differentially expressed genes in gte4 were coregulated in eml1/2. Through chromatin immunoprecipitation followed by deep sequencing, we found that GTE4 and EML2 co-occupy protein-coding genes enriched with both histone acetylation and H3K4me3, exerting a synergistic effect on the association of the GTE4-EML complex with chromatin. The association of GTE4 with chromatin requires both its bromodomain and EML-interacting domain.

Here, we examined the evolutionary landscape among UGTs in 28 fully sequenced species from early algae to angiosperms. Our findings revealed a distinctive expansion and contraction of UGTs in the G and H groups in tea (Camellia sinensis), respectively. Whole-genome duplication and tandem duplication events jointly drove the massive expansion of UGTs, and the interplay of natural and artificial selection has resulted in marked functional divergence within the G group of the sinensis-type tea population. In Cluster II of group G, differences in substrate selection (e.g. abscisic acid) of the enzymes encoded by UGT genes led to their functional diversification, and these genes influence tolerance to abiotic stresses such as low temperature and drought via different modes of positive and negative regulation, respectively. UGTs in Cluster III of the G group have diverse aroma substrate preferences, which contribute a diverse aroma spectrum of the sinensis-type tea population. All Cluster III genes respond to low-temperature stress, whereas UGTs within Cluster III-1, shaped by artificial selection, are unresponsive to drought. This suggests that artificial selection of tea plants focused on improving quality and cold tolerance as primary targets.","PeriodicalId":20186,"journal":{"name":"Plant Cell","volume":" ","pages":""},"PeriodicalIF":10.0,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11663605/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142375792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
