O mutualismo entre formigas e plantas está entre as interações mais bem estudadas. Seu estudo vem sugerindo e testando hipóteses ecológicas e evolucionárias aplicáveis a muitas outras formas de mutualismo. A cada ano relações mais especializadas entre formigas e plantas são descobertas. Entre estas relações podemos mencionar a obtenção de abrigo e/ou alimento pela formiga, que implica no fornecimento de proteção a planta contra herbivoria, dispersão de suas sementes e, até, polinização de suas flores. Nesta revisão são discutidos os tipos de interações mutualísticas entre formigas e plantas ex

Résumé :

A utilização das plantas para fins medicinais remota à antiguidade, entretanto com o avanço da medicina e da indústria farmacêutica, acentuou-se o uso de medicamentos industrializados, fato este que pode refletir na diminuição do conhecimento e uso das plantas medicinais na atualidade. E buscando-se compreender as percepções de estudantes sobre as plantas medicinais, o objetivo principal deste trabalho foi realizar um levantamento de dados sobre a diversidade de conhecimento de plantas medicinais dos alunos do Ensino Médio de uma escola pública do estado do Amapá.

Résumé :

Cinnamomum zeylanicum Blume (Lauraceae) é cultivada para produção de folhas, cascas e raízes, devido as suas propriedades aromáticas e condimentares. Mas apesar de ser uma planta resistente, C. zeylanicum está sujeita ao ataque de vários insetos e ácaros durante o seu desenvolvimento, sendo estas pragas responsáveis por uma redução considerável no rendimento dos cultivos. O objetivo desse estudo foi registrar e caracterizar o ataque por formigas cortadeiras em plantas de C. zeylanicum em Braço do Trombudo, Santa Catarina, Brasil entre janeiro e março de 2010.

Résumé :

26 pp. Geographically, Arizona can be divided roughly into four areas, southwest, central, southeast, and northern. These regions correspond with four climatic zones, allowing a large and diverse number of plants to be grown for landscaping purposes. But, interestingly, in this desert environment many of the parasitic diseases in landscape plants are caused by a limited number of plant pathogens. This publication discusses some of those diseases that are sufficiently important to the urban plants in all areas Arizona.

Résumé :

AbstractThe ecosystem of the earth is fascinating and intricate. The interactions that occur in the soil affect its characteristics as a substrate for development and activity of soil microorganisms and plants. The majority of terrestrial plants have a symbiotic, mutually beneficial interaction with the soil fungi known as arbuscular mycorrhizal fungi (AMF). These microorganisms expand the root’s absorption region, which improves the plant’s ability to absorb nutrients. The symbiont gets plant carbohydrates in return for accomplishing its life cycle. Additionally, AMF aids in the adaptation of

While much of contemporary architectural discourse around plants tends to focus on their aesthetic aspects, origins, and potential uses—such as to provide ornament, drought- resistance and/or cooling, etc.—self-seeded plants, weeds and other undesirables tend to be less of a direct subject of interest and object of study within the discipline.This paper proposes an alternative relationship between architecture and plants, in which urban and self-seeded flora are used as forensic material and studied as evidence of urban change, spatial politics and movements of people, ideas, and construction

Most bacterial plant pathogens colonize the surface of healthy plants as epiphytes before colonizing internally and initiating disease. The epiphytic phase of these pathogens is thus an important aspect of their epidemiology and a stage at which chemical and biological control is aimed. However, little is known of the genes and phenotypes that contribute to the ability of bacteria to grow on leaves and survive the variable physical environment in this habitat. In addition, while genes such as hrp awr and others which confer pathogenicity and in planta growth ability have been described, their

At least ten Latin American and Caribbean countries have pledged to achieve carbon neutrality. Has electricity planning in the region evolved towards reaching these goals?

We find that fossil fuel planned capacity has decreased by 47% since 2019, mainly due to

Résumé :

The function of the 30-kilodalton movement protein (MP) of tobacco mosaic virus (TMV) is to facilitate cell-to-cell movement of viral progeny in infected plants. Our earlier findings have indicated that this protein has a direct effect on plasmodesmal function. In addition, these studies demonstrated that constitutive expression of the TMV MP gene (under the control of the CaMV 35S promoter) in transgenic tobacco plants significantly affects carbon metabolism in source leaves and alters the biomass distribution between the various plant organs. The long-term goal of the proposed research was t

Résumé :

We show better-managed firms are more dynamic in plant acquisitions, disposals, openings, and closings in U.S. Census and international data. Better-managed firms also birth better-managed plants and improve the performance of the plants they acquire. To explain these findings, we build a model with two key elements. First, management is a combination of firm-level management ability (e.g. CEO quality), which can be transferred to all plants, and plant-level management practices, which can be changed through intangible investment (e.g. consulting or training). Second, management both raises pr

Résumé :

Phytophagous insects respond to chemicals from their host plants in a number of ways, including orientation or attraction in response to volatiles produced by plants. Orientation to odors from host plants may occur in order to locate food, mates, or oviposition sites. A detailed understanding of these behaviors are the chemical stimuli evoking them may provide useful means for attracting and trapping insect pests of crop plants. Heliothine moths (Helicoverpa and Heliothis herein) include a number of major pests of cultivated crop plants throughout the world. In North America, these include Hel
