Article Synopsis
  • Thaumatin-like proteins (TLPs) are proteins in plants that help them defend against stress, particularly in winter conditions, as seen in the plant Ammopiptanthus mongolicus.
  • Research revealed that specific TLP genes, like AmTLP25, increase in expression during winter and when plants face cold or osmotic stress, enhancing their survival.
  • The study found that the AmWRKY14 transcription factor boosts AmTLP25 expression in winter, suggesting a regulatory pathway that helps A. mongolicus adapt to cold climates, enhancing our understanding of plant resilience.

Fifty-three shade tolerance genes with 281 alleles in the SCSGP were identified directly using gene-allele sequence as markers in RTM GWAS, from which optimized crosses, evolutionary motivators, and gene-allele networks were explored. Shade tolerance is a key for optimal cultivation of soybean inter/relay-cropped with corn. To explore the shade tolerance gene-allele system in the southern China soybean germplasm, we proposed using gene-allele sequence markers (GASMs) in a restricted two-stage multi-locus model genome-wide association study (GASM-RTM-GWAS).

Article Synopsis
  • Dematiaceous Fonsecaea monophora is a significant pathogen responsible for chromoblastomycosis, with melanization influenced by type I polyketide synthase (PKS) involving multiple genes.
  • Study focused on two PKS genes in F. monophora, revealing that deletion of the thioesterase (TE) domain in one gene leads to decreased expression of PKS and other related genes, impacting melanin synthesis and fungal growth.
  • The research highlights the importance of the TE enzyme for pathogenicity and suggests that targeting TE could present a new approach in antifungal drug development.

Chromoblastomycosis (CBM) is a chronic disease caused by several species of dematiaceous fungi. In this study, a regional collection of 45 CBM cases was conducted in Guangdong, China, a hyper-endemic area of CBM. Epidemiology findings indicated that the mean age of cases was 61.

Background: Bean pyralid is one of the major leaf-feeding insects that affect soybean crops. DNA methylation can control the networks of gene expressions, and it plays an important role in responses to biotic stress. However, at present the genome-wide DNA methylation profile of the soybean resistance to bean pyralid has not been reported so far.

Background: Nitrogen (N) is a major nutrient element for crop growth. In plants, the members of the peptide transporter (PTR) gene family may involve in nitrate uptake and transport. Here, we identified PTR gene family in rice and analyzed their expression profile in near-isogenic lines.

Mesial temporal lobe epilepsy (mTLE), a very common chronic neurological disorder, is frequently accompanied by neurodegeneration in the hippocampus, resulting in hippocampal sclerosis (HS); HS is the most common morphological correlate of drug resistance in mTLE patients. Incomplete knowledge of pathological changes in mTLE with HS complicates its therapy. Growing evidence indicates a role of lipid signaling pathways in epileptogenesis; thus, lipid signals emerge as potential biomarkers for the onset and evolving course of this epileptic disorder, and are potential therapeutic agents and targets.

An 80-year-old women complained of painful erythema, papules, nodules on her right wrist for 9 months. Granuloma and inflammatory infiltrates with septate fungal hyphae were observed in pathological sections. Growth of demaciatious fungus on SDA was confirmed to be Exophiala spinifera by microscopic appearance and ITS rDNA sequencing.

Soybean is one of the most important oil crops in the world. Bean pyralid is a major leaf-feeding insect of soybean. In order to screen out the functional genes and regulatory pathways related to the resistance for bean pyralid larvae, the small RNA and transcriptome sequencing were performed based on the highly resistant material (Gantai-2-2) and highly susceptible material (Wan 82-178) of soybean.

Background: Soybean is one of most important oilseed crop worldwide, however, its production is often limited by many insect pests. Bean pyralid is one of the major soybean leaf-feeding insects in China. To explore the defense mechanisms of soybean resistance to bean pyralid, the comparative transcriptome sequencing was completed between the leaves infested with bean pyralid larvae and no worm of soybean (Gantai-2-2 and Wan82-178) on the Illumina HiSeq™ 2000 platform.

Background: Lamprosema indicate is a major leaf feeding insect pest to soybean, which has caused serious yield losses in central and southern China. To explore the defense mechanisms of soybean resistance to Lamprosema indicate, a highly resistant line (Gantai-2-2) and a highly susceptible line (Wan 82-178) were exposed to Lamprosema indicate larval feedings for 0 h and 48 h, and the differential proteomic analyses of these two lines were carried out.

Results: The results showed that 31 differentially expressed proteins (DEPs) were identified in the Gantai-2-2 when comparing 48 h feeding with 0 h feeding, and 53 DEPs were identified in the Wan 82-178.

  • Chlamydia trachomatis is a major bacterial STI in China, and this study aimed to better understand its genotypes among men who have sex with men (MSM) and men who have sex with women (MSW) in Guangzhou using a high-resolution method called MLVA-ompA.
  • The research collected and analyzed specimens from 51 MSM and 96 MSW, identifying 144 samples with distinct ompA genotypes, revealing that MSM had 4 genotypes while MSW had 9, with no mixed infections present.
  • Findings showed significant differences in the prevalent genotypes between the two groups, with higher discriminatory power from the MLVA-ompA method compared to

Little is known regarding protein responses to syphilis infection in cerebrospinal fluid (CSF) of patients presenting with neurosyphilis. Protein and antibody arrays offer a new opportunity to gain insights into global protein expression profiles in these patients. Here we obtained CSF samples from 46 syphilis patients, 25 of which diagnosed as having central nervous system involvement based on clinical and laboratory findings.

  • - The study monitored gonococcal antimicrobial resistance in Neisseria gonorrhoeae isolates in Guangzhou, China, focusing on penicillin and tetracycline resistance from 2002 to 2012, finding significant increases in resistance rates over the years.
  • - Researchers identified 429 penicillinase-producing N. gonorrhoeae (PPNG) and 639 tetracycline-resistant N. gonorrhoeae (TRNG) isolates, with the prevalence of both types showing substantial growth throughout the study period.
  • - The majority of PPNG isolates had Asian-type plasmids, while African-type plasmids emerged by 2008, and all TRNG isolates carried Dutch-type plasmids, with consistently high levels of
