However, there are currently few reports on the starch biosynthesis regulatory mechanism in sorghum grains. Here, we employed RNA-seq and ATAC-seq strategies to discover the transcriptional regulation network responsible for starch biosynthesis in sorghum grains. Our results profiled all mRNAs in the sorghum grains at nine development stages covering the inflorescence, and grains from 3 to 30 days after pollination (DAP). Analysis of the gene sets determined temporal programs of gene expression, including thousands of transcription factor (TF) genes. We found a close correlation between the sequentially expressed gene sets and distinct cellular and metabolic programs of the developing grains. The cis -elements serving as binding sites of multiple TFs were identified via a comparative ATAC-seq assay. Cis -elements capable of binding TFs were also identified within the promoter regions of starch biosynthesis related genes (SBRGs). Moreover, the NAC family TF of SbNAC68 highly expressed in developing grains and demonstrated co-expression patterns with SBRGs. Furthermore, SbNAC68 was confirmed to bind to 5′-ACGCAA-3′, a typical motif of binding site for the TFs from NAC family, to affect the promotor activities of SBRGs and regulate their transcriptions. Collectively, through multiply omics strategies and the case dissection of SbNAC68, the present study provides molecular insights of transcriptional regulations into starch biosynthesis in sorghum grains. • Genome-wide genes and TFs in developing sorghum grains were correspondingly profiled via RNA-seq and ATAC-seq. • Numerous cis-elements within the promoter regions of starch biosynthesis related genes (SBRGs) and other genes that bind to multiple TFs were identified via a comparative ATAC-seq assay. • Case dissection of SbNAC68 discovered molecular insights of transcriptional regulations into starch biosynthesis in sorghum grains.","PeriodicalId":20224,"journal":{"name":"Plant Diversity","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147919362","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}

Despite its horticultural, medicinal, and ecological importance, a well-resolved phylogeny and coherent infrageneric classification are still lacking. Here, we reconstruct a robust phylogeny for <i>Clematis</i> using a phylogenomic approach and revise its infrageneric taxonomy. We incorporated 198 samples representing 151 species, two subspecies, and 12 varieties, covering all subgenera and most sections worldwide, obtained from both fresh and herbarium material. Nuclear single nucleotide polymorphisms (SNPs) and complete plastid genomes were assembled for phylogenetic analyses. We also prepared a nuclear ribosomal ITS (nrITS) dataset comprising 171 species, two subspecies, and 12 varieties (217 samples) to include as many species as possible for phylogenetic inference. Phylogenies based on plastid genomes and nrITS exhibited limited resolution and modest support, highlighting challenges in resolving certain relationships. Nuclear SNP analyses yielded a robust phylogenetic tree with 22 well-supported clades corresponding to 22 sections, with most previously recognized subgenera and sections not recovered as monophyletic. Ancestral state reconstruction of 12 key morphological characters revealed multiple independent origins of character states. This study presents the first comprehensive sectional classification for <i>Clematis</i> based on robust phylogenomic evidence, redefines morphological characteristics for each section, and resolves long-standing taxonomic ambiguities.

Here, we investigate the genetic architecture, demographic history, and adaptive potential of <i>Oreocharis mileensis</i>, a threatened karst-endemic resurrection plant. We generated a high-quality, phased genome assembly of 3.99 Gb covering two haplotypes with a contig N50 of 124 Mb, revealing three lineage-specific whole-genome duplication events following the ancestral γ event. Population resequencing of 107 individuals across 10 localities uncovered strong population structure, low gene flow, and high genetic differentiation, indicating long-term isolation. Core populations exhibited elevated inbreeding, whereas peripheral populations showed reduced runs of homozygosity and fewer deleterious mutations, suggesting historical demographic events and possible purging effects. pRDA analyses on putatively adaptive loci revealed that genetic variation is primarily aligned with pre-existing population structure. Functional annotation of putatively adaptive SNPs identified genes associated with drought tolerance and rapid recovery after rewatering. Gradient Forest models revealed substantial genomic offset in almost all populations, highlighting their increased vulnerability under projected climate scenarios. Based on these findings, we propose conservation strategies that include delineating eight genetically informed management units and facilitating assisted gene flow among compatible populations. For highly isolated populations, ex situ conservation, habitat restoration, and cultivation for horticultural use are recommended to mitigate genetic erosion and enhance adaptive resilience.
