Genome characterization of a begomovirus isolated from Brazilian Carica papaya plants

Abstract Papaya ( Carica papaya L.) plants are susceptible to several viral pathogens. However, information regarding papaya-associated DNA viruses in Latin America is limited. In this study, we collected symptomatic papaya plants in Baraúna, Rio Grande do Norte, Brazil, and scre...

Land use intensification results in abrupt transitions between extensively and intensively managed grasslands

Abstract Understanding whether land use intensification causes regime shifts (i.e. persistent, large changes in ecosystem states) is of key importance for management, particularly if these shifts occur abruptly as thresholds in land use intensity are crossed. Further, these thres...

Stem-cell modeling of cerebellar dysfunction of Angelman syndrome

Angelman syndrome is a severe neurodevelopmental disorder caused by loss of function of the maternal allele of the neuron-specific imprinted gene UBE3A. Although Angelman syndrome presents with developmental delay, ataxia, epilepsy, and speech impairment, the contribution of spec...

Taxonomic revision of the genus Methanobrevibacter, description of Methanomonile shimae gen. nov. sp. nov., and proposal of Methanobrevibacteraceae fam. nov

Recent phylogenomic analyses revealed that the genus Methanobrevibacter , which consists almost exclusively of representatives from the intestinal tract of animals, is severely underclassified. Based on the large relative evolutionary divergence between individual subclades, memb...

Rhodococcus erythropolis ICBD2 membrane and cell wall adaptation to long-chain alkane degradation

Abstract Long-chain hydrocarbon biodegradation is limited by its low bioavailability. Specific strains degrade hydrocarbons including long-chain alkanes. Rhodococcus erythropolis ICBD2 is a hydrocarbonoclastic bacterium isolated from a chronically petroleum-contaminated coastal s...

The first complete genome sequence of iris yellow spot virus from South America and comparative analysis with isolates of different geographic origin

Abstract We report the first complete nucleotide sequence of an isolate of iris yellow spot virus (IYSV; Orthotospovirus iridimaculaflavi ) from Brazil. Isolate Br-25 was collected in 2025 in Imbuia, Santa Catarina, from symptomatic onion scapes. The genome of IYSV-Br-25 consiste...
