Article Synopsis
  • - Patchouli, an important medicinal plant used in traditional medicine, is facing a severe leaf spot disease in Guangxi, China, with over 50% of plants affected, showing symptoms like brown spots and yellowing.
  • - Researchers collected and analyzed affected leaves from various locations, isolating a fungal pathogen believed to be Aspergillus sp., with 90% of the sampled plants yielding similar fungal characteristics.
  • - For further identification, the internal transcribed spacer (ITS) region and the β-tubulin (TUB) gene of the fungal isolates were sequenced to confirm their identity.

Millettia speciosa Champ, renowned for its diverse applications in traditional medicine, is extensively cultivated in the Guangxi region of China, spanning roughly 5,973 hectares. In July 2021, a plantation in Yulin, Guangxi, China (22°64'N; 110°29'E), exhibited severe leaf spot disease on M. speciosa.

Star anise (Illicium verum), a valuable spice tree, faces significant threats from fungal diseases, particularly Alternaria leaf spot. This study investigates the potential of a soil-derived actinomycete strain, YG-5, as a biocontrol agent against Alternaria tenuissima, the causative pathogen on Alternaria leaf spot in star anise. Through comprehensive morphology, physiology, biochemistry, and genetic analyses, we identified the isolate as Streptomyces sp.

Article Synopsis
  • - Nanhaia speciosa, or Niudali, is a medicinal vine in the Leguminosae family, grown primarily for its edible tubers, which have antioxidant and antibacterial properties and extensive cultivation in Guangxi, China.
  • - In July 2021, a plantation in Yulin, Guangxi showed concerning leaf spot symptoms, impacting over 40% of the plants, characterized by small yellow spots evolving into dark lesions, and resulting in wilting foliage.
  • - Pathogen investigations revealed seven isolates identical in morphology to Corynespora sp., specifically C. cassiicola, confirmed through DNA analysis, which matched with high identity percentages in the genomic database.

Targeting oncogenic mutant p53 represents an attractive strategy for cancer treatment due to the high frequency of gain-of-function mutations and ectopic expression in various cancer types. Despite extensive efforts, the absence of a druggable active site for small molecules has rendered these mutants therapeutically non-actionable. Here we develop a selective and effective proteolysis-targeting chimera (PROTAC) for p53-R175H, a common hotspot mutant with dominant-negative and oncogenic activity.

Receptors for Activated C Kinase 1 (RACK1s) are a kind of multifunction scaffold protein that plays an important role in cell signal transductions and animal development. However, the function of RACK1 in the Chinese honeybee Apis cerana cerana is little known. Here, we isolated and identified a RACK1 gene from Apis cerana cerana, named AccRACK1.

Background: Cassava (Manihot esculenta Crantz) is a major crop extensively cultivated in the tropics as both an important source of calories and a promising source for biofuel production. Although stable gene expression have been used for transgenic breeding and gene function study, a quick, easy and large-scale transformation platform has been in urgent need for gene functional characterization, especially after the cassava full genome was sequenced.

Methods: Fully expanded leaves from in vitro plantlets of Manihot esculenta were used to optimize the concentrations of cellulase R-10 and macerozyme R-10 for obtaining protoplasts with the highest yield and viability.

A fully synthetic self-adjuvanting cancer vaccine candidate was constructed through covalent conjugation of invariant natural killer T (iNKT) cell ligand α-galactosylceramide (αGalCer) with sialyl Tn (STn), a representative tumor-associated carbohydrate antigen (TACA). This two-component vaccine STn-αGalCer is devoid of antigenic peptide, featuring the well-defined structure with high simplicity. STn-αGalCer showed remarkable efficacy in inducing antibody class switching from IgM to STn-specific IgG.
