Contributes to Salt and Drought Stress Tolerance via Modulating Anthocyanin Accumulation and ROS-Scavenging System in Sweet Potato.

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 transcription factors in balancing anthocyanin biosynthesis and abiotic stress in sweet potato ( (L.) Lam.

Sweet potato NAC transcription factor negatively regulates plant growth by causing leaf curling and reducing photosynthetic efficiency.

Leaves comprise one of the most important organs for plant growth and development. Although there have been some reports on leaf development and the establishment of leaf polarity, their regulatory mechanisms are not very clear. In this study, we isolated a NAC (NAM, ATAF, and CUC) transcription factor (TF), i.

Genome-Wide Characterization of the PIFs Family in Sweet Potato and Functional Identification of under Drought and Wilt Stresses.

Phytochrome-interacting factors (PIFs) are essential for plant growth, development, and defense responses. However, research on the in sweet potato has been insufficient to date. In this study, we identified genes in the cultivated hexaploid sweet potato () and its two wild relatives, , and .

A Novel WRKY Transcription Factor from , ItfWRKY70, Confers Drought Tolerance in Sweet Potato.

WRKY transcription factors are one of the important families in plants, and have important roles in plant growth, abiotic stress responses, and defense regulation. In this study, we isolated a WRKY gene, , from the wild relative of sweet potato (H.B.

A novel sweetpotato RING-H2 type E3 ubiquitin ligase gene IbATL38 enhances salt tolerance in transgenic Arabidopsis.

Arabidopsis Toxicos en Levadura (ATL) proteins compose a subfamily of E3 ubiquitin ligases and play major roles in regulating plant growth, cold, drought, oxidative stresses response and pathogen defense in plants. However, the role in enhancing salt tolerance has not been reported to date. Here, we cloned a novel RING-H2 type E3 ubiquitin ligase gene, named IbATL38, from sweetpotato cultivar Lushu 3.

Synthesis of copolymers using dendronized polyethylene glycol and assay of their blood compatibility and antibacterial adhesion activity.

Thrombus formation and microbial invasion are two major complications that impede the widespread application of blood-contacting devices. The development of new materials that have blood compatibility and antibacterial adhesion activity has gained increased attention. In this study, a new class of polymers composed of hydrophilic dendronized polyethylene glycol (PEG) methacrylate and hydrophobic octyne monomethyl ether-glycidyl methacrylate was synthesized via click chemistry and free radical polymerization.

Surface modification of PDMS by surface-initiated atom transfer radical polymerization of water-soluble dendronized PEG methacrylate.

The current paper reports the synthesis of a highly hydrophilic, antifouling dendronized poly(3,4,5-tris(2-(2-(2-hydroxylethoxy)ethoxy)ethoxy)benzyl methacrylate) (PolyPEG) brush using surface initiated atom transfer radical polymerization (SI-ATRP) on PDMS substrates. The PDMS substrates were first oxidized in H(2)SO(4)/H(2)O(2) solution to transform the Si-CH(3) groups on their surfaces into Si-OH groups. Subsequently, a surface initiator for ATRP was immobilized onto the PDMS surface, and PolyPEG was finally grafted onto the PDMS surface via copper-mediated ATRP.

Folate-decorated hybrid polymeric nanoparticles for chemically and physically combined paclitaxel loading and targeted delivery.

In this study, folate-functionalized hybrid polymeric nanoparticles (NPs) were prepared as carriers of low water solubility paclitaxel for tumor targeting, which were composed of monomethoxy-poly(ethylene glycol)-b-poly(lactide)-paclitaxel (MPEG-PLA-paclitaxel) and d-α-tocopheryl polyethylene glycol 1000 succinate (TPGS)-folate (TPGS-FOL). NPs with various weight ratios of MPEG-PLA-paclitaxel and TPGS-FOL were prepared using a solvent extraction/evaporation method, which can also physically encapsulate paclitaxel. The size, size distribution, surface charge, and morphology of the drug-loaded NPs were characterized using a Zetasizer Nano ZS, scanning electron microscope (SEM), and atomic force microscopy (AFM).
