Lycopene β-cyclase (LCYB) is an essential enzyme that catalyzes the conversion of lycopene into α-carotene and β-carotene in carotenoid biosynthesis pathway. However, roles underlying mechanisms LCYB gene plant responses to abiotic stresses are rarely known. This has not been used improve contents sweetpotato, Ipomoea batatas (L.) Lam.. In present study, a new allele gene, named IbLCYB2, was isolated from storage roots sweetpotato line HVB-3. Its overexpression significantly increased...
Summary Drought limits crop development and yields. bHLH (basic helix–loop–helix) transcription factors play critical roles in regulating the drought response many plants, but their this process sweet potato are unknown. Here, we report that two proteins, IbbHLH118 IbbHLH66, opposite ABA‐mediated potato. ABA treatment repressed expression induced IbbHLH66 drought‐tolerant line Xushu55‐2. Overexpressing reduced tolerance, whereas overexpressing enhanced directly binds to E‐boxes promoters of...
Basic helix–loop–helix (bHLH) transcription factors extensively affect various physiological processes in plant metabolism, growth, and abiotic stress. However, the regulation mechanism of bHLH balancing anthocyanin biosynthesis stress sweet potato (Ipomoea batata (L.) Lam.) remains unclear. Previously, transcriptome analysis revealed genes that were differentially expressed among purple-fleshed cultivar ‘Jingshu 6’ its anthocyanin-rich mutant ‘JS6-5’. Here, we selected one these potential...
As a major worldwide root crop, the mechanism underlying storage yield formation has always been hot topic in sweet potato [Ipomoea batatas (L.) Lam.]. Previously, we conducted transcriptome database of differentially expressed genes between cultivated cultivar "Xushu18," its diploid wild relative Ipomoea triloba without root, and their interspecific somatic hybrid XT1 with medium-sized root. We selected one these candidate genes, IbNF-YA1, for subsequent analysis. IbNF-YA1 encodes nuclear...
Nuclear Factor Y (NF-Y) represents a group of transcription factors commonly present in higher eukaryotes, typically consisting three subunits: NF-YA, NF-YB, and NF-YC. They play crucial roles the embryonic development, photosynthesis, flowering, abiotic stress responses, other essential processes plants. To better understand genome-wide NF-Y domain-containing proteins, protein physicochemical properties, chromosomal localization, synteny, phylogenetic relationships, genomic structure,...
SWEET (Sugar Will Eventually be Exported Transporter) proteins play vital roles in the transport of sugars, contributing to regulation plant development, hormone signaling, and responses abiotic stress. In this study, we identified 57 NtSWEETs tobacco (Nicotiana tabacum L.), then their physicochemical properties, chromosomal localization, synteny, phylogenetic relationships, genomic structure, promoter cis-elements, protein interaction network, tissue specificity, expression pattern were...
The cytochrome P450 superfamily (CYP450) is one of the largest protein families in plants, and its members play diverse roles primary secondary metabolic biosynthesis. In this study, CYP450 family gene IbCYP82D47 was cloned from high carotenoid line HVB-3 sweet potato (Ipomoea batatas). harbored two transmembrane domains dynamically localized between plastid stroma membrane. Overexpression not only increased total carotenoid, lutein, zeaxanthin violaxanthin contents by 32.2-48.0%,...
