Insecticide Resistance and Its Management in Two Invasive Cryptic Species of < em > Bemisia tabaci < /em > in China
Int J Mol Sci. 2023 Mar 23;24(7):6048. doi: 10.3390/ijms24076048.ABSTRACTThe sweet potato whitefly Bemisia tabaci is a major agricultural pest with a wide host range throughout the world. The species designation for B. tabaci includes numerous distinct cryptic species or biotypes. Two invasive B. tabaci biotypes, MEAM1 (B) and MED (Q), were found in China at the end of the 20th century and at the beginning of the 21st century. MEAM1 (B) and MED (Q) show higher pesticide resistance levels than native strains, and the levels of resistance vary with changes in insecticide selection pressure. Recent studies have revealed metab...

GSE227409 Identification of a DAMP receptor and its cognate peptide ligand in sweet potato (Ipomoea batatas)
Contributors : Hsueh-Han Lu ; Anja K Meents ; Judith Fliegmann ; Ming-Jing Hwang ; Ching-Shu Suen ; Georg Felix ; Axel Mith öfer ; Kai-Wun YehSeries Type : Expression profiling by high throughput sequencingOrganism : Ipomoea batatasWe identified a leucine-rich repeat receptor kinase (IbLRR-RK1) that is induced upon wounding and herbivory, and related to peptide-elicitor receptors (PEPRs) from tomato and Arabidopsis. We also identified a gene encoding a precursor protein comprising a peptide ligand (IbPep1) for IbLRR-RK1.RNAseq of I. batatas reveals differentially expressed genes (DEGs) upon IbPep1 and IbHypSysIV tr...

Ozone exposure tunes the physicochemical properties of sweet potato starch by modifying its molecular structure
Int J Biol Macromol. 2023 Mar 11:124002. doi: 10.1016/j.ijbiomac.2023.124002. Online ahead of print.ABSTRACTOzonation is an efficient method for improving the technical performance of some starches, but the feasibility of its use for sweet potato starch remains unknown. The effects of aqueous ozonation on the multi-scale structure and physicochemical properties of sweet potato starch were explored. Structurally, ozonation did not generate significant alterations at the granular level (size, morphology, lamellar structure, and long-range and short-range ordered structures), but led to tremendous changes at the molecular lev...

Effects of primary, secondary and tertiary structures on functional properties of thermoplastic starch biopolymer blend films
Int J Biol Macromol. 2023 Mar 10:124006. doi: 10.1016/j.ijbiomac.2023.124006. Online ahead of print.ABSTRACTTo better understand the correlation between structure and properties in thermoplastic starch biopolymer blend films, the effects of amylose content, chain length distribution of amylopectin and molecular orientation of thermoplastic sweet potato starch (TSPS) and thermoplastic pea starch (TPES) on microstructure and functional properties of thermoplastic starch biopolymer blend films were studied. After thermoplastic extrusion, the amylose contents of TSPS and TPES decreased by 16.10 % and 13.13 %, respectively. The...

Characterization and complete genome sequence analysis of the novel phage RPZH3 infecting Ralstonia solanacearum
AbstractA novel lyticRalstonia phage, RPZH3, was isolated from the soil of a tobacco field via a double agar overlay plaque assay. The phage has an icosahedral head 75 ± 5 nm in diameter with a short tail about 15 ± 5 nm in length. It was able to infect 18 out of 30 tested strains ofR. solanacearum isolated from tobacco, sweet potato, tomato, pepper, and eggplant. The latent period of the phage was 80 min, and the burst period was 60 min with a burst size of about 27 pfu/cell. The phage was stable at pH 4 –12 at 28°C, and it was also stable at temperatures from 45°C to 60°C at pH 7.0. The complete genome of...

In this study, sweet potato &beta;-amylase (SPA) was modified by methoxy polyethylene glycol maleimide (molecular weight 5000, Mal-mPEG5000) to obtain the Mal-mPEG5000-SPA modified &beta;-amylase and the interaction mechanism between SPA and Mal-mPEG5000 was investigated. the changes in the functional groups of different amide bands and modifications in the secondary structure of enzyme protein were analyzed using infrared spectroscopy and circular dichroism spectroscopy. The addition of Mal-mPEG5000 transformed the random curl in the SPA secondary structure into a helix structure, forming a folded structur...
