Abiotic stresses are critical delimiters for the increased productivity and cultivation expansion of sweet potato (Ipomoea batatas), a root crop with worldwide importance. The production glycine betaine (GB) improves plant tolerance to various abiotic without strong phenotypic changes, providing feasible approach improve stable yield under unfavorable conditions. gene encoding aldehyde dehydrogenase (BADH) is involved in biosynthesis GB plants, accumulation by heterologous overexpression...
Dihydroflavonol-4-reductase (DFR) is a key enzyme in the catalysis of stereospecific reduction dihydroflavonols to leucoanthocyanidins anthocyanin biosynthesis. In purple sweet potato (Ipomoea batatas Lam.) cv. Ayamurasaki, expression IbDFR gene was strongly associated with accumulation leaves, stems and roots. Overexpression Arabidopsis tt3 mutants fully complemented pigmentation phenotype seed coat, cotyledon hypocotyl. Downregulation transgenic (DFRi) using an RNAi approach dramatically...
CRISPR/Cas9-mediated genome editing is a powerful technology that has been used for the genetic modification of number crop species. In order to evaluate efficacy CRISPR/Cas9 in root crop, sweet potato (Ipomoea batatas), two starch biosynthetic pathway genes, IbGBSSI (encoding granule-bound synthase I), and IbSBEII branching enzyme II), were targeted starch-type cultivar Xushu22 carotenoid-rich Taizhong6. I. batatas was transformed using binary vector, which Cas9 gene driven by Arabidopsis...
Salinity and low temperature are the main limiting factors for sweet potato ( Ipomoea batatas ) growth agricultural productivity. Various studies have shown that plant NHX ‐type antiporter plays a crucial role in regulating tolerance to salt stress by intracellular Na + compartmentalization. The Arabidopsis thaliana AtNHX1 gene encodes vacuolar /H was introduced into cultivar Xushu‐22 Agrobacterium ‐mediated transformation confer abiotic tolerance. Stable insertion of genome its expression...
There is no direct evidence of the effect lignin metabolism on early storage root development in sweet potato. In this study, we found that heterologous expression maize leaf color (Lc) gene potato increased anthocyanin pigment accumulation whole plant and resulted reduced size with an length/width ratio, low yield less starch content roots. RT-PCR analysis revealed dramatic up-regulation genes involved biosynthesis pathway developing roots, leading to greater Lc transgenic lines, compared...
The initiation and development of storage roots (SRs) are intricately regulated by a transcriptional regulatory network. One key challenge is to accurately pinpoint the tipping point during transition from pre-swelling SRs identify core regulators governing such critical transition. To solve this problem, we performed dynamic network biomarker (DNB) analysis transcriptomic dynamics root in Ipomoea batatas (sweet potato). First, our identified stage-specific expression patterns for...
Abstract Storage roots of sweet potato are important sink organs for photoassimilates and energy, carbohydrate metabolism in storage affects yield starch production. Our previous study showed that H + -pyrophosphatase (IbVP1) plays a vital role mitigating iron deficiency positively controls fibrous root growth. However, its roles regulating production have not been investigated. In this study, we found IbVP1 overexpression improved the photosynthesis ability sucrose content source leaves...
Hollow stems have independently evolved multiple times across the plant kingdom, and play crucial roles in development various environmental adaptations. However, mechanisms underlying stem hollowness remain poorly understood. Water spinach (Ipomoea aquatica) is one of few hollow-stemmed plants Convolvulaceae family, its hollow are essential for thriving aquatic environments. Using histochemical staining transcriptome analysis, we identified programmed cell death (PCD) involved cavity...
Glycosylation contributes to the diversity and stability of anthocyanins in plants. The process is catalysed by various glucosyltransferases using different anthocyanidin aglycones glycosyl donors. In this study, we found that an 3-O-glucoside-2″-O-glucosyltransferase (3GGT) from purple sweet potato (Ipomoea batatas) catalyses conversion 3-O-glucoside into 3-O-sophoroside, which functionally 3GGT ortholog Arabidopsis. Phylogenetic analysis indicated regioselectivity uridine-5'-diphosphate...
Sweepoviruses have been identified globally and cause substantial yield losses cultivar decline in sweet potato. This study aimed to investigate the interaction between sweepovirus plant host by analyzing function of viral protein C4 Sweet potato leaf curl virus-Jiangsu (SPLCV-JS), a cloned from diseased plants East China. Ectopic expression Arabidopsis altered development drastically with phenotypic changes including curling, seedling twisting, deformation floral tissues reduction pollen...
Stem nematode (Ditylenchus destructor) is one of most serious diseases that limit the productivity and quality sweet potato (Ipomoea batatas), a root crop with worldwide importance for food security nutrition improvement. Hence, there global demand developing varieties are resistant to disease. In this study, we have investigated interference stem infectivity by expression small interfering RNAs (siRNAs) in transgenic homologous unc-15 gene, which affects muscle protein paramyosin pathogen....
Summary Iron (Fe) deficiency is one of the most common micronutrient deficiencies limiting crop production globally, especially in arid regions because decreased availability iron alkaline soils. Sweet potato [ Ipomoea batatas (L.) Lam.] grows well and tolerant to Fe deficiency. Here, we report that transcription type I H + ‐pyrophosphatase (H ‐ PP ase) gene Ib VP 1 sweet plants was strongly induced by auxin hydroponics, improving acquisition via increased rhizosphere acidification...
<title>Abstract</title> Host-virus interactions determine infection outcomes, with cellular heterogeneity playing a critical role in the dynamic interplay between host immune responses and viral evasion strategies. While animal plant viruses use different mechanisms for cell entry, tropism is essential pathogenesis across both kingdoms. To examine this overarching hypothesis, we studied sweet potato virus disease, most devastating disease affecting (<italic>Ipomoea batatas</italic>), which...
Abstract Although the sweet potato, Ipomoea batatas , is seventh most important crop in world and fourth significant China, its genome has not yet been sequenced. The reason, at least part, that proven very difficult to assemble, being hexaploid highly polymorphic; it a presumptive composition of two B 1 four 2 component genomes (B ). By using novel haplotyping method based on de novo assembly, however, we have produced half haplotype-resolved from ∼267Gb paired-end sequence reads amounting...
Abstract The hexaploid sweet potato is one of the most important root crops worldwide. However, its genetic origins, especially that tetraploid progenitor, are unclear. In this study, we conceived a pipeline consisting genome-wide variation-based phylogeny and novel haplotype-based phylogenetic analysis (HPA) to determine accession CIP695141 Ipomoea batatas 4x from Peru progenitor potato. We detected biased gene exchanges between subgenomes. B 1 2 subgenome conversions were almost 3-fold...
