Synthesis and antifungal activity of novel amide derivatives from quinic acid against the sweet potato pathogen Ceratocystis fimbriata.

Background: Ceratocystis fimbriata is a fungal pathogen that infects sweet potato roots, producing enormous economic losses. Cyclic polyhydroxy compound quinic acid is a common metabolite synthesized in plant tissues, including sweet potato tubers, showing weak antifungal properties. Although several O-acylated quinic acid derivatives have been synthesized and found in nature and their antifungal properties have been explored, derivatives based on modification of the carboxylic acid have never been evaluated.

N-terminal truncated trehalose-6-phosphate synthase 1 gene (△NIbTPS1) enhances the tolerance of sweet potato to abiotic stress.

Sweet potato [Ipomoea batatas (L.) Lam], the crop with the seventh highest annual production globally, is susceptible to various adverse environmental influences, and the study of stress-resistant genes is important for improving its tolerance to abiotic stress. The enzyme trehalose-6-phosphate synthase (TPS) is indispensable in the one pathway for synthesizing trehalose in plants.

Overexpression of sweetpotato glutamylcysteine synthetase (IbGCS) in Arabidopsis confers tolerance to drought and salt stresses.

Various environmental stresses induce the production of reactive oxygen species (ROS), which have deleterious effects on plant cells. Glutathione (GSH) is an antioxidant used to counteract reactive oxygen species. Glutathione is produced by glutamylcysteine synthetase (GCS) and glutathione synthetase (GS).

IbINV Positively Regulates Resistance to Black Rot Disease Caused by in Sweet Potato.

Black rot disease, caused by Ellis & Halsted, severely affects both plant growth and post-harvest storage of sweet potatoes. Invertase (INV) enzymes play essential roles in hydrolyzing sucrose into glucose and fructose and participate in the regulation of plant defense responses. However, little is known about the functions of INV in the growth and responses to black rot disease in sweet potato.

Black nightshade () typically grows as a weed species, but it is also widely used as an herb to treat stomach ulcers and dermal infections in many countries (Jabamalairaj et al. 2019). In April 2023, extensive root galls similar to those associated with by root-knot nematodes (RKNs), spp.

Transcriptome Characterization and Gene Changes Induced by in Sweetpotato Roots.

Sweetpotato () is an important root crop that is infected by in both seedling and root stages, causing irregular black or brown disease spots and root rot and canker. This study aims to use RNA sequencing technology to investigate the dynamic changes in root transcriptome profiles between control check and roots at 6 h, 24 h, 3 days, and 5 days post-inoculation (hpi/dpi) with . The results showed that the defense reaction of sweetpotato could be divided into an early step (6 and 24 hpi) without symptoms and a late step to respond to infection (3 and 5 dpi).

Whole Genomic Sequence Analysis of Human Adenovirus Species C Shows Frequent Recombination in Tianjin, China.

Human adenovirus species C (HAdV-C) is frequently detected in China and worldwide. For the first time, 16 HAdV-C strains were isolated from sewage water (14 strains) and hospitalised children with diarrhoea (2 strains,) in Tianjin, China. Nearly complete genome data were successfully obtained for these viruses.

Charged multivesicular body protein 2B ameliorates biliary injury in the liver from donation after cardiac death rats via autophagy with air-oxygenated normothermic machine perfusion.

Normothermic machine perfusion (NMP) could provide a curative treatment to reduce biliary injury in donation after cardiac death (DCD) donor livers; however, the underlying mechanisms remain poorly understood. In a rat model, our study compared air-oxygenated NMP to hyperoxygenated NMP and found that air-oxygenated NMP improved DCD functional recovery. Here, we found that the charged multivesicular body protein 2B (CHMP2B) expression was substantially elevated in the intrahepatic biliary duct endothelium of the cold-preserved rat DCD liver after air-oxygenated NMP or in biliary endothelial cells under hypoxia/physoxia.

MG132 protects against lung injury following brain death in rats.

Brain death (BD) results in injury to organs and induces lung donor dysfunction. Since the 20S proteasome abnormality is associated with a variety of diseases, the present study investigated whether it was involved in lung injury following BD in rats, and the effects of the proteasome inhibitor MG132 on lung injury was also assessed. Rats were assigned to a BD group or a control sham group.

Development of a dual RT-RPA detection for Sweet potato feathery mottle virus and Sweet potato chlorotic stuntvirus.

The disease co-infected by Sweet potato feathery mottle virus (SPFMV) and Sweet potato chlorotic stunt virus (SPCSV) is devastating in sweet potato, as it would give rise to the serious losses in both production and quality. Consequently, it is conducive for preventing and controlling this disease to detect these two viruses accurately and timely. Here we developed and optimized a dual reverse transcription recombinase polymerase amplification (RT-RPA) for rapid and accurate detection of SPFMV and SPCSV.
