Bomidin: An Optimized Antimicrobial Peptide With Broad Antiviral Activity Against Enveloped Viruses.

The rapid evolution of highly infectious pathogens is a major threat to global public health. In the front line of defense against bacteria, fungi, and viruses, antimicrobial peptides (AMPs) are naturally produced by all living organisms and offer new possibilities for next-generation antibiotic development. However, the low yields and difficulties in the extraction and purification of AMPs have hindered their industry and scientific research applications.

Metaproteomics associated with severe early childhood caries highlights the differences in salivary proteins.

Objective: To investigate the salivary metaproteomic characteristics of the children with and without severe early childhood caries (S-ECC).

Design: In this study, we collected unstimulated saliva samples from 34 children (age 3-4 years) with caries free (NC, dmfs (= index of decayed, missing due to caries, or filled tooth surfaces) = 0, n = 23) and with S-ECC (dmfs≥10, n = 11). Salivary proteins were extracted and reduced, and then a Liquid Chromatography/Mass Spectrometry system was used to identify proteins.

QTL-BSA: A Bulked Segregant Analysis and Visualization Pipeline for QTL-seq.

In recent years, the application of Whole Genome Sequencing (WGS) on plants has generated sufficient data for the identification of trait-associated genomic loci or genes. A high-throughput genome-assisted QTL-seq strategy, combined with bulked-segregant analysis and WGS of two bulked populations from a segregating progeny with opposite phenotypic trait values, has gained increasing popularities in research community. However, there is no publicly available user friendly software for the identification and visualization.

Circulating proteomic panels for diagnosis and risk stratification of acute-on-chronic liver failure in patients with viral hepatitis B.

Chronic HBV infection (CHB) can lead to acute-on-chronic liver failure (HBV-ACLF) characterized by high mortality. This study aimed to reveal ACLF-related proteomic alterations, from which protein based diagnostic and prognostic scores for HBV-ACLF were developed. : Ten healthy controls, 16 CHB, and 19 HBV-ACLF according to COSSH (Chinese group on the study of severe hepatitis B) criteria were enrolled to obtain the comprehensive proteomic portrait related to HBV-ACLF initiation and progression.

Proteomic approach to understand the molecular physiology of symbiotic interaction between Piriformospora indica and Brassica napus.

Many studies have been now focused on the promising approach of fungal endophytes to protect the plant from nutrient deficiency and environmental stresses along with better development and productivity. Quantitative and qualitative protein characteristics are regulated at genomic, transcriptomic, and posttranscriptional levels. Here, we used integrated in-depth proteome analyses to characterize the relationship between endophyte Piriformospora indica and Brassica napus plant highlighting its potential involvement in symbiosis and overall growth and development of the plant.

Piriformospora indica promotes growth, seed yield and quality of Brassica napus L.

In current scenario, crop productivity is being challenged by decreasing soil fertility. To cope up with this problem, different beneficial microbes are explored to increase the crop productivity with value additions. In this study, Brassica napus L.

Acyl-CoA oxidase 1 is involved in γ-decalactone release from peach (Prunus persica) fruit.

γ-Decalactone accumulation in peach mesocarp was highly correlated with ACX enzyme activity and natural PpACX1 content. Adding the purified recombinant PpACX1 induced γ-decalactone biosynthesis in cultured mesocarp discs in vitro. Previous gene expression studies have implied that acyl coenzyme A oxidase (ACX) is related to lactones synthesis, the characteristic aroma compounds of peach.

Piriformospora indica confers cadmium tolerance in Nicotiana tabacum.

Piriformospora indica, a root-colonizing endophytic fungus of Sebacinales, promotes plant growth and confers resistance against biotic and abiotic stresses. In order to confirm the influence of P. indica on growth, proline, malondialdehyde (MDA), chlorophyll, and cadmium (Cd) amounts in Nicotiana tabacum under Cd stress, hydroponics, pot and field trials were conducted.

Genetic diversity of male and female Chinese bayberry (Myrica rubra) populations and identification of sex-associated markers.

Background: Chinese bayberry (Myrica rubra Sieb. & Zucc.) is an important subtropical evergreen fruit tree in southern China.

Microbial community structure in fermentation process of Shaoxing rice wine by Illumina-based metagenomic sequencing.

Background: To understand the role of the community structure of microbes in the environment in the fermentation of Shaoxing rice wine, samples collected from a wine factory were subjected to Illumina-based metagenomic sequencing.

Results: De novo assembly of the sequencing reads allowed the characterisation of more than 23 thousand microbial genes derived from 1.7 and 1.

Curcumin-supplemented diets increase superoxide dismutase activity and mean lifespan in Drosophila.

Curcumin is a polyphenolic bioactive compound in turmeric. We examined if antioxidant effects of curcumin are associated with lifespan extension in Drosophila. In this experiment, females and males of Drosophila were fed diets either containing no curcumin (C0) or supplemented with curcumin at 0.

Molecular identification of cDNA, immunolocalization, and expression of a putative odorant-binding protein from an Asian honey bee, Apis cerana cerana.

An odorant-binding protein cDNA (Acer-ASP2) was cloned and characterized from antennae of adult workers of an Asian honey bee, Apis cerana cerana F. (Hymenoptera: Apidae). The full-length open reading frame of Acer-ASP2 cDNA was 429 bp, encoding 142 amino acids.

Proteomic identification of the silkworm (Bombyx mori L) prothoracic glands during the fifth instar stage.

Although the ecdysteroid of the silkworm had been studied for decades, the proteome of the prothoracic gland, the primary source of ecdysteroid hormones, has not been studied previously. In the present paper, we utilized a proteomic approach to investigate the fifth instar prothoracic gland during the growth and development of the silkworm, Bombyx mori L. The two-dimensional electrophoresis results showed that the majority of proteins were acidic proteins, especially concentrated in the area of 25-65 kDa, with pI values of between 4 and 7, and the difference was not distinct.

Sequence analysis of functional Apisimin-2 cDNA from royal jelly of Chinese honeybee and its expression in Escherichia coli.

Apisimin is one of the functional peptides from royal jelly. The aim of this study was to analyze and in vitro express a new gene encoding Acc-apisimin-2 from Chinese honeybee (Apis cerana cerana) in Escherichia coli. Ninety-six clones containing apisimin expressed sequence tag (EST) were identified from 8568 effective ESTs of the cDNA library of Chinese honeybee worker heads.

A preliminary genetic linkage map of the Pacific abalone Haliotis discus hannai Ino.

Preliminary genetic linkage maps were constructed for the Pacific abalone (Haliotis discus hannai Ino) using amplified fragment length polymorphism (AFLP), randomly amplified polymorphic DNA (RAPD), and microsatellite markers segregating in a F(1) family. Nine microsatellite loci, 41 RAPD, and 2688 AFLP markers were genotyped in the parents and 86 progeny of the mapping family. Among the 2738 markers, 384 (including 365 AFLP markers, 10 RAPD markers, and 9 microsatellite loci) were polymorphic and segregated in one or both parents: 241 in the female and 146 in the male.
