Natural allelic variation of basic helix-loop-helix transcription factor 25 regulates carotenoid biosynthesis in sweet potato.

Carotenoid-rich orange-fleshed sweet potato (OFSP) is an important staple diet and source of nutrition in developing countries, including Africa and Asia. However, the regulation of carotenoid biosynthesis remains to be better understood. A natural allelic variation closely linked to carotenoid biosynthesis was identified in the promoter region of the IbbHLH25 gene that encodes a basic helix-loop-helix (bHLH) transcription factor, by transcriptome and haplotype analyses of different flesh colour sweet potato accessions.

The transcription factor IbNAC29 positively regulates the carotenoid accumulation in sweet potato.

Carotenoid is a tetraterpene pigment beneficial for human health. Although the carotenoid biosynthesis pathway has been extensively studied in plants, relatively little is known about their regulation in sweet potato. Previously, we conducted the transcriptome database of differentially expressed genes between the sweet potato () cultivar 'Weiduoli' and its high-carotenoid mutant 'HVB-3'.

Probiotics to prevent necrotizing enterocolitis and reduce mortality in neonates: A meta-analysis.

Background: Probiotics are gradually being used as a supplementation to prevent necrotizing enterocolitis (NEC) and reduce mortality in neonates. We performed an updated meta-analysis to systematically evaluate the efficacy and safety of prophylactic probiotic supplementation for preventing NEC.

Methods: The databases including PubMed, Embase, Scopus, Web of Science, and China National Knowledge Infrastructure were used to search the relevant articles.

A novel small open reading frame gene, , enhances drought tolerance in transgenic sweet potato.

Small open reading frames (sORFs) can encode functional polypeptides or act as -translational regulators in stress responses in eukaryotes. Their number and potential importance have only recently become clear in plants. In this study, we identified a novel sORF gene in sweet potato, , which encoded the 83-amino acid polypeptide containing an EGF_CA domain.

The IbPYL8-IbbHLH66-IbbHLH118 complex mediates the abscisic acid-dependent drought response in sweet potato.

Drought limits crop development and yields. bHLH (basic helix-loop-helix) transcription factors play critical roles in regulating the drought response in many plants, but their roles in this process in sweet potato are unknown. Here, we report that two bHLH proteins, IbbHLH118 and IbbHLH66, play opposite roles in the ABA-mediated drought response in sweet potato.

Genetic polymorphism and forensic application of 23 autosomal STR loci in the Han population of Panjin City, Liaoning Province, Northeastern China.

Background: Short tandem repeats (STRs) are consecutive repetition of a repeat motif and widely used in forensic medicine and human genetics because of their high polymorphism.

Subjects And Methods: In the current study, 23 autosomal STR loci were genotyped from 1263 unrelated healthy individuals living in Panjin City, Liaoning Province, Northeastern China using the VeriFiler Express PCR Amplification Kit. The population comparison was performed between the Panjin Han population and the other relevant groups to further explore the structure of Panjin Han and its relationship with the other groups.

A cytochrome P450 superfamily gene, IbCYP82D47, increases carotenoid contents in transgenic sweet potato.

The cytochrome P450 superfamily (CYP450) is one of the largest protein families in plants, and its members play diverse roles in primary and secondary metabolic biosynthesis. In this study, the CYP450 family gene IbCYP82D47 was cloned from the high carotenoid line HVB-3 of sweet potato (Ipomoea batatas). The IbCYP82D47 protein harbored two transmembrane domains and dynamically localized between plastid stroma and membrane.

The Sweetpotato BTB-TAZ Protein Gene, , Enhances Drought Tolerance in Transgenic .

BTB-TAZ (BT)-domain proteins regulate plant development and pathogen defense. However, their roles in resistance to abiotic stresses remain largely unknown. In this study, we found that the sweetpotato BT protein-encoding gene significantly enhanced the drought tolerance of .

A Novel Sweetpotato Transcription Factor Gene Enhances Drought Tolerance in Transgenic .

Several members of the MYB transcription factor family have been found to regulate growth, developmental processes, metabolism, and biotic and abiotic stress responses in plants. However, the role of MYB116 in plants is still unclear. In this study, a MYB transcription factor gene was cloned and characterized from the sweetpotato [ (L.
