However, detecting the resulting mutations by analysis of sequencing data remains time-consuming and inefficient. In response to this issue, we designed SuperDecode, an integrated software toolkit for analyzing editing outcomes using a range of sequencing strategies. SuperDecode comprises three modules, DSDecodeMS, HiDecode, and LaDecode, each designed to automatically decode mutations from Sanger, high-throughput short-read (next-generation sequencing), and long-read sequencing data (third-generation sequencing), respectively, from targeted PCR amplicons. By leveraging specific strategies for constructing sequencing libraries of pooled multiple amplicons, HiDecode and LaDecode facilitate large-scale identification of mutations induced by single or multiplex target-site editing in a cost-effective manner. We demonstrate the efficacy of SuperDecode by analyzing mutations produced using different genome editing tools (CRISPR/Cas, base editing, prime editing) in different materials (diploid and tetraploid rice, protoplasts), underscoring its versatility in decoding genome editing outcomes across different applications. Furthermore, this toolkit can be used to analyze other genetic variations, as exemplified by its ability to estimate the C-to-U editing rate of the cellular RNA of a mitochondrial gene. SuperDecode offers both a standalone software package and a web-based version, ensuring its easy access and broad compatibility across diverse computer systems. Thus, SuperDecode provides a comprehensive platform for analyzing a wide array of mutations, advancing the utility of genome editing for scientific research and genetic engineering.</p>","PeriodicalId":19012,"journal":{"name":"Molecular Plant","volume":" ","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143567749","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}

The CG and CHG hypermethylation tend to localize within gene bodies, with a significant proportion being de novo generated. In contrast, the CHH hypermethylation is concentrated in centromeric and pericentromeric regions, primarily being reinforced methylation. Mechanistically, DNA 3' blocks regulate the DREAM complex to induce CG and CHG methylation. Moreover, they utilize the RdDM pathway to induce CHH hypermethylation.

In this study, using TurboID-based proximity labeling, we identify the retromer subcomplex comprising sorting nexin 1 (SNX1), SNX2a, and SNX2b as interacting partners of ATG8. Remarkably, SNX proteins decorate ATG8-labeled autophagosomes and facilitate their coordinated movement along microtubules.

Furthermore, we show that the microtubule-associated protein CLASP is a bridge, connecting the SNX-ATG8-decorated autophagosomes to the microtubules. Genetically, the clasp-1 mutant phenotype resembles that of plants with disrupted SNXs or microtubule networks, displaying diminished autophagosome motility and reduced autophagic flux.

By comprehensively analyzing the binding targets of all the HSFs, we found that HSFs act in a network, with upstream sensory HSFs acting in a transcriptional cascade to activate downstream HSFs and protective proteins. The upstream sensory HSFs are activated by heat at the protein level via a modular prion-like domain (PrD) structure. PrD1 enables HSF sequestration via chaperone binding, allowing release under heat shock. Activated HSFs are recruited into transcriptionally active foci via PrD2, enabling the formation of DNA loops between heat-responsive promoters and enhancer motifs, boosting gene expression days after a priming heat stress.

First, GEFormer uses gMLP to extract local and global features among SNPs. Then, Omni-dimensional Dynamic Convolution is used to extract the dynamic and comprehensive features of multiple environmental factors within each day, taking into consideration the real growth pattern of crops. A linear attention mechanism is used to capture the temporal features of environmental changes. Finally, GEFormer uses a gating mechanism to effectively fuse the genomic and environmental features. We examined the accuracy of GEFormer for predicting important agronomic traits of maize, rice, and wheat under three experimental scenarios: untested genotypes in tested environments, tested genotypes in untested environments, and untested genotypes in untested environments. The results showed that GEFormer outperforms six cutting-edge statistical learning methods and four machine learning methods, especially with great advantages under the scenario of untested genotypes in untested environments. In addition, we used GEFormer for three real-world breeding applications: phenotype prediction in unknown environments, hybrid phenotype prediction using an inbred population, and cross-population phenotype prediction.

Metabolomic analysis of the A. sesquipedale flower revealed a substantial release of oximes at dusk during the blooming stage. By integrating metabolomic and transcriptomic correlation approaches, flavin-containing monooxygenases (FMOs) encoded by six tandem-repeat genes in the A. sesquipedale genome are identified as catalyzing the formation of oximes present. Further in vitro and in vivo assays confirm the function of FMOs in the oxime biosynthesis. We designate these FMOs as orchid oxime synthases 1-6.
