Med Sci Monit

December 2024

Department of Dermatology, First Affiliated Hospital of Kunming Medical University, Yunnan Provincial Dermatology Hospital, Kunming, Yunnan, China.

Acne vulgaris is a chronic inflammatory disease of the hair follicle-sebaceous gland unit and is the most common skin disorder worldwide. Although it can occur at any age, it predominantly affects young individuals, manifesting as comedones, papules, pustules, cysts, and nodules, primarily in the sebaceous-rich areas of the face, often in a symmetrical distribution. The development of acne vulgaris is believed to result from a combination of genetic and environmental factors, including sun exposure, skincare habits, diet, sleep patterns, and psychological stress, all of which can induce or exacerbate the condition.

Rapid Sex Chromosome Turnover in African Clawed Frogs (Xenopus) and the Origins of New Sex Chromosomes.

Mol Biol Evol

December 2024

UMR 7179, Mécanismes Adaptatifs et Evolution, Muséum national d'Histoire naturelle CNRS, Paris, France.

Sex chromosomes of some closely related species are not homologous, and sex chromosome turnover is often attributed to mechanisms that involve linkage to or recombination arrest around sex-determining loci. We examined sex chromosome turnover and recombination landscapes in African clawed frogs (genus Xenopus) with reduced representation genome sequences from 929 individuals from 19 species. We recovered extensive variation in sex chromosomes, including at least eight nonhomologous sex-associated regions-five newly reported here, with most maintaining female heterogamety, but two independent origins of Y chromosomes.

Article Synopsis
  • Plants release volatile organic compounds (VOCs) like green leaf volatiles (GLVs) and pentyl leaf volatiles (PLVs) to communicate and respond to stressors, with PLVs being less studied despite their significance.
  • Disrupting the maize-specific lipoxygenase ZmLOX6 reduces the production of PLVs, leading to decreased resistance against fall armyworm and fungal pathogens, as well as altered metabolite profiles.
  • The study highlights a potential competition between the production pathways of PLVs and GLVs, showing that enhancing PLV levels can improve plant resistance to herbivores and specific pathogens while revealing the divergent roles of these compounds in plant defense mechanisms.

Stink bug species emerged as major insect pests of cotton in the mid-southern United States following the eradication of the boll weevil and the introduction of genetically modified Bt cotton for lepidopteran pests. Considering the limited number of chemical classes available for insect control, further insights into other chemistries are necessary to inform management strategies with the overall goal of establishing and maintaining the most cost efficient and efficacious control programs for stink bugs in Alabama. The insect growth regulator, novaluron, has shown control of tarnished plant bugs, but little research has been done on its effect in stink bugs.

Novel polymycoviruses are encapsidated in filamentous virions.

J Virol

December 2024

National Key Laboratory for Germplasm Innovation and Utilization of Horticultural Crops, Wuhan, China.

is a relatively new viral family that was established nearly 5 years ago, but their viral morphologies (naked or encapsidated) remain controversial since only one member namely, filamentous virus 1 (CcFV1), was identified as being encapsidated in filamentous virions. Here, three novel double-stranded RNA (dsRNA) viruses belonging to the family were identified in three phytopathogenic fungal strains and tentatively named -sinensis polymycovirus 1 (PcsPmV1), and polymycovirus 1 and 2 (PhcPmV1 and 2), respectively. PcsPmV1 and PhcPmVs have five or six genomic dsRNAs, ranging from 1,055 to 2,405 bp, encoding five or seven putative open reading frames (ORFs), of which ORF1 encodes an RNA-dependent RNA polymerase, ORF5 encodes a prolein-alanine-serine-rich (P-A-S-rich) protein behaving as coat protein (CP); and dsRNAs 4 and 6 encode putative proteins with unknown functions and share no detectable identities with known viral sequences.

LysM effectors are suppressors of chitin-triggered plant immunity in biotrophic and hemibiotrophic fungi. In necrotrophic fungi, LysM effectors might induce a mechanism to suppress host immunity during the short asymptomatic phase they establish before these fungi activate plant defenses and induce host cell death leading to necrosis. Here, we characterize a secreted LysM protein from a major necrotrophic fungus, Botrytis cinerea, called BcLysM1.

Agricultural pesticides have historically been a critical tool in controlling pests and diseases, preventing widespread suffering and crop losses that led to catastrophes such as the Great Irish Famine (1845-1852) and the Cotton Boll Weevil Infestation (1915-1916). However, their usage has brought challenges, including resistance development, secondary pest outbreaks, harm to non-target organisms like pollinators, and environmental contamination. In response to these concerns, integrated pest management (IPM) has emerged as a comprehensive approach, emphasizing non-chemical pest control methods such as cultural practices, biological control, and crop rotation, with pesticides as the last resort.

Department of Microbiology and Biotechnology, Max Rubner-Institut, Hermann-Weigmann-Str 1, D-24103, Kiel, Germany.

Plant sterols (PSs) exhibit intrinsic functions such as antibacterial effects. Their effects simultaneously on both host-mediated and bacteria-mediated pathogenesis are not yet fully understood. We hypothesized that when absorptive cells, defensive cells and detoxer cells are cultured together, their convergent response to an infectious pathogen depends on the molecular mimicry between the ingested sterols and their own defensive lipids.
