Abstract Salvia bowleyana is a traditional Chinese medicinal plant that source of nutritional supplements rich in salvianolic acid B and potential experimental system for the exploration biosynthesis Labiatae. Here, we report high‐quality chromosome‐scale genome assembly S. covering 462.44 Mb, with scaffold N50 value 57.96 Mb 44,044 annotated protein‐coding genes. Evolutionary analysis revealed an estimated divergence time between its close relative miltiorrhiza ~3.94 million years. We also...

Abstract Isochrysis galbana is considered an ideal bait for functional foods and nutraceuticals of humans because its high fucoxanthin (Fx) content. However, multi-omics analysis the regulatory networks Fx biosynthesis in I. has not been reported. In this study, we report a high-quality genome assembly LG007, which size 92.73 Mb, with contig N50 6.99 Mb 14,900 protein-coding genes. Phylogenetic confirmed monophyly Haptophyta, sister to Emiliania huxleyi Chrysochromulina tobinii. Evolutionary...

Abstract The Podostemaceae are ecologically and morphologically unusual aquatic angiosperms that survive only in rivers with pristine hydrology high water quality at a relatively risk of extinction. taxonomic status has always been controversial. Here, we report the first high-quality genome assembly for Cladopus chinensis Podostemaceae, obtained by incorporating Hi-C, Illumina PacBio sequencing. We generated an 827.92 Mb contig N50 1.42 27,370 annotated protein-coding genes. assembled size...

Cyclocarya paliurus, a well-known nutrient and beverage plant, is under development for use in functional health care products best natural organic foods. We hypothesis that the composition metabolic accumulation of hypoglycemic metabolites exhibit significant differences depending on harvest time. Therefore, it great significance to establish time C. paliurus leaves further healthy teas other products. However, detail compositions molecular mechanisms nutrients biosynthesis during different...

Isochrysis galbana , as a potential accumulator of fucoxanthin, has become valuable material to develop functional foods for humans. Our previous research revealed that green light effectively promotes the accumulation fucoxanthin in I. but there is little on chromatin accessibility process transcriptional regulation. This study was conducted reveal mechanism biosynthesis under by analyzing promoter and gene expression profiles. Differentially accessible regions (DARs)-associated genes were...

Chitooligosaccharide is a kind of functional food, which the degradation product chitosan (COS) catalyzed by endo-chitosanase (COSE) enzyme. A COSE with molecular weight 34 kDa was purified and characterized from newly isolated Mitsuaria sp. C4 (C4), 38.46% recovery rate 4.79-fold purification were achieved. The exhibited optimum activity at 40°C pH 7.2 significantly inhibited in presence Cu 2+ Fe 3+ . K m V min toward COS 2.449 g/L 0.042 g/min/L, respectively. highest reached 8.344 U/ml...

Transglutaminase-catalyzed reactions can be used widely to modify the functional properties of food proteins, biopharmaceuticals and in tissue engineering. Streptomyces mobaraensis is important for industrial fermentation because its rapid, low-cost growth easy cultivation. We cloned transglutaminase (TGase) gene from S. mobaraensis; was 1224-bp (65.22% G+C), encoding 407 amino acids. Then, expression vector pL99-T constructed by cloning TGase into plasmid pL99. introduced using conjugation...

Isochrysis galbana is an important producer in the aquatic ecosystem because of its rich fucoxanthin content and fast growth. However, little known about evolutionary adaptation to live a specific, complex harsh environment. We report high-quality genome sequence I. LG007, which has 92.73 Mb size, contig N50 6.99 14,900 protein-coding genes. Phylogenomic inferences confirmed monophyly Haptophyta, showing sister E. huxleyi C. tobinii. Evolutionary analysis revealed estimated divergence from...
