Understanding maize genotype behavior under stunt complex pressure [PDF]

Ciência e Agrotecnologia
The stunt complex, transmitted by Dalbulus maidis, has become one of the main maize diseases in recent years in Brazil and Latin America. Genetic resistance is one of the best ways to control and prevent plant diseases due to its efficiency, low ...

Characterisation of the bacteriomes harboured by major wireworm pest species in the Canadian Prairies

Insect Molecular Biology, Volume 34, Issue 1, Page 203-217, February 2025.
The bacteriomes of five of the most important agricultural pests in the Canadian Prairies were characterised. Wireworms have diverse and taxon‐rich bacterial communities, with different species having a distinct composition and a small number of genera predominating.

The swimming of a deforming helix [PDF]

Eur. Phys. J. E (2018) 41, 119, 2018
Many microorganisms and artificial microswimmers use helical appendages in order to generate locomotion. Though often rotated so as to produce thrust, some species of bacteria such Spiroplasma, Rhodobacter sphaeroides and Spirochetes induce movement by deforming a helical-shaped body.

A Novel Lineage of Endosymbiotic Actinomycetales: Genome Reduction and Acquisition of New Functions in Bifidobacteriaceae Associated With Termite Gut Flagellates

Environmental Microbiology, Volume 27, Issue 1, January 2025.
We have characterised several novel genera of Bifidobacteriaceae that colonise the cytoplasm of cellulolytic flagellates. Horizontal gene transfer played an important role in their adaptation to the intracellular environment. However, progressive genome erosion led to the loss of biosynthetic capacities that formed the basis of an originally ...

Structural analysis of the spiroplasma virus, SpV4: implications for evolutionary variation to obtain host diversity among the Microviridae [PDF]

, 1998
Background: Spiroplasma virus, SpV4, is a small, non-enveloped virus that infects the helical mollicute Spiroplasma melliferum. SpV4 exhibits several similarities to the Chlamydia phage, Chp1, and the Coliphages α3, φK, G4 and φX174. All of these viruses

Endosymbiont-based immunity in Drosophila melanogaster against parasitic nematode infection. [PDF]

PLoS ONE, 2018
Associations between endosymbiotic bacteria and their hosts represent a complex ecosystem within organisms ranging from humans to protozoa. Drosophila species are known to naturally harbor Wolbachia and Spiroplasma endosymbionts, which play a protective ...

Potential Functions of the Gut Microbiome and Modulation Strategies for Improving Aquatic Animal Growth

Reviews in Aquaculture, Volume 17, Issue 1, January 2025.
ABSTRACT The increase in the body weight of animals, a pivotal indicator closely tied to production, is important to the aquaculture industry. Despite remarkable variability in gut microbiomes, which are intricately associated with their hosts and affect overall performance, fitness, and physiological outcomes, across individuals and species, the ...

Spiroplasma – an emerging arthropod-borne pathogen?

Annals of Agricultural and Environmental Medicine, 2015
Spiroplasma is a genus of wall-less, low-GC, small Gram-positive bacteria of the internal contractile cytoskeleton, with helical morphology and motility. The genus is classified within the class Mollicutes.

Sex‐biased gene content is associated with sex chromosome turnover in Danaini butterflies

Molecular Ecology, Volume 33, Issue 24, December 2024.
Abstract Sex chromosomes play an outsized role in adaptation and speciation, and thus deserve particular attention in evolutionary genomics. In particular, fusions between sex chromosomes and autosomes can produce neo‐sex chromosomes, which offer important insights into the evolutionary dynamics of sex chromosomes. Here, we investigate the evolutionary
