In this study, we leveraged a panel consisting of 348 diverse inbred maize lines to explore the genetic and molecular mechanisms that control kernel Met levels. A genome-wide association study followed by transcriptomic analysis identified the deSUMOylating isopeptidase gene ZmDeSI2. Further biochemical experiments revealed that ZmDeSI2 directly reduces the SUMOylation and accumulation of the sulfite reductase ZmSIR, thereby repressing Met accumulation. Natural variants in the ZmDeSI2 promoter region were found to serve as key determinants of the expression of this gene, predominantly due to the absence or presence of a ZmWRKY105 transcription factor binding site. The elite ZmDeSI2^Hap2 haplotype without this binding site in the ZmDeSI2 promoter was associated with a 1.36-fold increase in Met levels in the kernels of modified near-isogenic lines generated through marker-assisted breeding. Taken together, these results provide new insights into the molecular processes that control Met biosynthesis, highlighting an elite natural variant suitable for application in maize breeding for Met biofortification.</p>","PeriodicalId":19012,"journal":{"name":"Molecular Plant","volume":"18 5","pages":"872-891"},"PeriodicalIF":17.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144028651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Owing to its large size and highly repetitive nature, there are numerous gaps in the globally used wheat Chinese Spring (CS) genome assembly. In this study, we generated a 14.46 Gb near-complete assembly of the CS genome, with a contig N50 of over 266 Mb and an overall base accuracy of 99.9963%. Among the 290 gaps that remained (26, 257, and 7 gaps from the A, B, and D subgenomes, respectively), 278 were extremely high-copy tandem repeats, whereas the remaining 12 were transposable-element-associated gaps. Four chromosome assemblies were completely gap-free, including chr1D, chr3D, chr4D, and chr5D. Extensive annotation of the near-complete genome revealed 151 405 high-confidence genes, of which 59 180 were newly annotated, including 7602 newly assembled genes. Except for the centromere of chr1B, which has a gap associated with superlong GAA repeat arrays, the centromeric sequences of all of the remaining 20 chromosomes were completely assembled. Our near-complete assembly revealed that the extent of tandem repeats, such as simple-sequence repeats, was highly uneven among different subgenomes. Similarly, the repeat compositions of the centromeres also varied among the three subgenomes. With the genome sequences of all six types of seed storage proteins (SSPs) fully assembled, the expression of ω-gliadin was found to be contributed entirely by the B subgenome, whereas the expression of the other five types of SSPs was most abundant from the D subgenome. The near-complete CS genome will serve as a valuable resource for genomic and functional genomic research and breeding of wheat as well as its related species.</p>","PeriodicalId":19012,"journal":{"name":"Molecular Plant","volume":" ","pages":"892-907"},"PeriodicalIF":17.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143414656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the identification of several transcription factors regulating nuclear-encoded photosynthetic gene transcription, transcription factors regulating plastid gene transcription are barely reported. Here, we report that BAI1 (\"albino\" in Chinese), a nucleus-plastid dual-targeted C2H2-type zinc-finger transcription factor in Arabidopsis, positively regulates and tunes the transcription of both nuclear and plastid genes. Knockout of BAI1 blocks chloroplast formation, producing albino seedlings and lethality. In plastids, BAI1 is a newly identified functional component of the pTAC (transcriptionally active chromosome complex), which interacts with another pTAC component, pTAC12/PAP5/HMR, to allow the effective assembly of plastid-encoded RNA polymerase (PEP) complexes. The transcript levels of PEP-dependent genes were reduced in the bai1 mutant. In contrast, the accumulation of nuclear-encoded RNA polymerase (NEP)-dependent transcripts was increased, suggesting that BAI1 is critical in maintaining PEP activity. BAI1 directly binds to the promoter regions of nuclear genes RbcSs and a plastid gene RbcL to activate their expression for RubisCO assembly. AtBAI1 homologs TaBAI1, GmBAI1a, and GmBAI1b from monocots and dicots can fully complement the defects of the Arabidopsis bai1 mutant. In contrast, Physcomitrium patens BAI1 (PpBAI1) only partially complements the bai1 mutant. Phylogenetic analysis of BAI1 and HMR uncovered that both components arose from late-diverging streptophyte algae, following a conserved evolutionary path during terrestrialization. In summary, this work unveils a BAI1-mediated transcription regulatory mechanism synchronizing the transcription of nuclear and plastid genes, necessary for hybrid photosynthetic complex assembly. This could be an intrinsic feature facilitating plant terrestrialization.</p>","PeriodicalId":19012,"journal":{"name":"Molecular Plant","volume":" ","pages":"833-852"},"PeriodicalIF":17.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143764449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
