Chili pepper (Capsicum) is known for its unique fruit pungency due to the presence of capsaicinoids. The evolutionary history capsaicinoid biosynthesis and mechanism their tissue specificity remain obscure lack high-quality Capsicum genomes. Here, we report two telomere-to-telomere (T2T) gap-free genomes C. annuum wild nonpungent relative rhomboideum investigate evolution in chili peppers. We precisely delineate centromeres, which high-copy tandem repeats but are extensively invaded by CRM...

Chinese motherwort (Leonurus japonicus), a member of Lamiaceae family, is commonly used medicinal herb for treating obstetrical and gynecological diseases, producing over 280 officinal natural products. Due to limited genomic resources, little progress has been made in deciphering the biosynthetic pathway valuable products L. japonicus. Here, we de novo assembled japonicus genome using high-coverage ONT long reads Hi-C reads. The chromosome-level assembly contained ten chromosomes...

The NAC proteins form one of the largest families plant-specific transcription factors (TFs) and play essential roles in developmental processes stress responses. In this study, we characterized a domain factor, OoNAC72, from legume Oxytropis ochrocephala. OoNAC72 was proved to be localized nuclei tobacco lower epidermal cells had transcriptional activation activity yeast, confirming its activity. expression could induced by drought, salinity exogenous abscisic acid (ABA) O. ochrocephala...

Grapevine (Vitis) is the oldest domesticated fruit crop with great cultural and economic importance. Here, we assemble annotate haplotype-resolved genomes of 72 Vitis accessions including 25 wild 47 cultivated grapevines, a complete genome V. vinifera. Coalescent phylogenomics 142 haplotype disentangles mysterious hybridization history revealing enormous genetic diversity among species. Pangenome analysis together phenotyping data reveals that European cultivars, more susceptible to most...

Lettuce (Lactuca sativa L.) is an annual plant of the Asteraceae family, commonly used as a fresh-cut vegetable and primary ingredient in salads. It rich vitamins, minerals, polyphenols, carotenoids, providing numerous health benefits. In 2021, lettuce achieved gross production value $16.6 billion worldwide, with China, United States, Western Europe leading producers (Food Agriculture, 2023Food AgricultureOrganization Nations.

Spatial multi-modal omics technology, highlighted by Nature Methods as an advanced biological technique in 2023, plays a critical role resolving regulatory processes with spatial context. Recently, graph neural networks based on K-nearest neighbor (KNN) graphs have gained prominence methods due to their ability model semantic relations between sequencing spots. However, the fixed KNN fails capture latent hidden inevitable data perturbations during process, resulting loss of information. In...

Abstract Multimodal omics provide deeper insight into the biological processes and cellular functions, especially transcriptomics proteomics. Computational methods have been proposed for integration of single-cell multimodal However, existing primarily concentrate on alignment different omics, overlooking unique information inherent in each type. Moreover, as majority cohorts only encompass one it becomes critical to transfer knowledge learnt from enhance unimodal analysis. Therefore, we a...

Abstract Lettuce ( Lactuca sativa L.) is a globally grown vegetable crop as the most popular salad ingredient. breeding crucial to enhancing yield, nutrition and disease resistance, but impeded by lacking high-quality genome resource. In addition, released genomes remain fragmented (with hundreds of gaps) incomplete with omitting pivotal centromeres telomeres. Here, we report 2.59 Gb complete telomere-to-telomere (T2T) assembly for lettuce. T2T analysis revealed unique genetic epigenetic...
