1. No fitness costs are induced by Spiroplasma infections of Aphis citricidus reared on two different host plants
Resumo Pulgões podem abrigar vários simbiontes secundários que alteram características ecológicas importantes, como defesa contra inimigos naturais, tolerância ao calor e utilização da planta hospedeira. Um desses simbiontes secundários, Spiroplasma, é estudado em Drosophila por alterar a razão sexual e interagir com o sistema imunológico do hosp

2. Holobionts and their hologenomes: Evolution with mixed modes of inheritance
Abstract Symbioses are ubiquitous and have played an influential role in the evolution of life on Earth. Genomic studies are now revealing a huge diversity of associations among hosts and their microbiotas, allowing us to characterize their complex ecological and evolutionary dynamics. The different transmission modes and the asynchronous cell proliferation

3. Arbuscular mycorrhizal fungi and dark septate fungi in plants associated with aquatic environments
ABSTRACT There have been several reports of symbionts in the roots of plants that live in aquatic environments. Arbuscular mycorrhizal fungi (AMF) are the most common microsymbionts and possibly recolonized the aquatic environment together with plants; however, their functions and the extent of their benefits are unclear. Furthermore, the presence of other g

4. Dark septate endophyte decreases stress on rice plants
Abstract Abiotic stress is one of the major limiting factors for plant development and productivity, which makes it important to identify microorganisms capable of increasing plant tolerance to stress. Dark septate endophytes can be symbionts of plants. In the present study, we evaluated the ability of dark septate endophytes isolates to reduce the effects o

5. Microbial Symbionts of Insects are the Focus of the First International Cooperative Biodiversity Group (ICBG) in Brazil
The basic aim of the ICBG (International Cooperative Biodiversity Group) program is to benefit both the host country and the global scientific community by discovering and developing new solutions to human health problems based on previously unexplored genetic resources. The first ICBG in Brazil is jointly supported by the Fogarty International Center of the

6. Microbial control of arthropod-borne disease
Arthropods harbor a diverse array of microbes that profoundly influence many aspects of host biology, including vector competence. Additionally, symbionts can be engineered to produce molecules that inhibit pathogens. Due to their intimate association with the host, microbes have developed strategies that facilitate their transmission, either horizontally or

7. Symbiont modulates expression of specific gene categories in Angomonas deanei
Trypanosomatids are parasites that cause disease in humans, animals, and plants. Most are non-pathogenic and some harbor a symbiotic bacterium. Endosymbiosis is part of the evolutionary process of vital cell functions such as respiration and photosynthesis. Angomonas deanei is an example of a symbiont-containing trypanosomatid. In this paper, we sought to in

9. Produção de mudas de acácia colonizadas com micorrizas e rizóbio em diferentes recipientes.
Realizou-se um experimento em casa de vegetação, com o objetivo de avaliar diferentes métodos na produção de mudas de Acacia mangium Willd, colonizadas com fungos micorrízicos arbusculares (FMAs) e rizóbio. O delineamento experimental foi o inteiramente casualizado num esquema fatorial 4x2 (controle, FMAs, rizóbio e FMAs + rizóbio x blocos prensados

11. Fungos micorrízicos arbusculares em solos de área de mineração de bauxita em reabilitação.
Apesar de a mineração de bauxita causar grandes alterações nas características do solo, com efeitos negativos nas micorrizas arbusculares, os efeitos da reabilitação de áreas mineradas sobre os fungos micorrízicos arbusculares (MA) e sua simbiose são pouco conhecidos. O objetivo deste trabalho foi avaliar a ocorrência, diversidade e eficiência do

12. Desenvolvimento ovariano e influência da cópula na maturação dos ovários de Diaphorina citri Kuwayama (Hemiptera: Psyllidae)
As many other insects with a restricted diet, the citrus psyllid Diaphorina citri Kuwayama, which vector the causing agent of the Huanglongbing, the bacteria Candidatus Liberibacter spp., is intimately associated with symbiotic microorganisms. These mutualist symbionts play a key role on their host nutritional ecology, and are vertically transmitted to the p
