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...

Antimicrobial, antibiofilm, and molecular docking evaluation of silver nanoparticles biosynthesized from Ocimum campechianum against Staphylococcus spp

Abstract Antimicrobial resistance and the overuse of antimicrobials have driven the search for innovative therapies, particularly those based on natural compounds and medicinal plant derivatives, aiming to develop new drugs. This study aimed to investigate the antimicrobial and a...

Rhizobium spp. strains improve the physiological attributes of Mimosa tenuiflora (Willd.) Poiret seedlings under different water contents

Rhizobium spp. inoculation is a strategy to promote plant growth and enhance drought tolerance, particularly in semiarid environments. This study evaluated the morphological and physiological responses of Mimosa tenuiflora (Willd.) seedlings inoculated with Rhizobium spp. under d...

Caste‐Associated Social Context Modulates Behavioural Interactions With Insecticide‐Exposed Individuals in Nasutitermes corniger (Termitidae: Nasutitermitinae)

ABSTRACT Termites are eusocial insects that maintain cohesion and exchange information through frequent physical interactions among nestmates. This social organisation underlies the principle of horizontal insecticide transfer, which is widely exploited as a termite control strat...

Seed germination of Schinus terebinthifolius as a function of fruit coloration

The present study aimed to evaluate the germination and germination speed index of Schinus terebinthifolius seeds obtained from fruits with different colors, considering the influence of different progenies. The study was conducted at the Federal Rural University of Pernambuco, i...

Beyond binary urban-rural classifications: a continuous urbanicity gradient index

Abstract Traditional urban-rural dichotomies fail to capture the complexity of contemporary settlement patterns, constraining both scientific progress and policy applications in urbanization research. To address this gap, we introduce the Urbanicity Gradient Index (UGI), a contin...
