1. Spilocaea pyracanthae causing leaf scab on loquat in Pakistan
ABSTRACT Loquat is attacked by many phytopathogenic fungi. Among these Spilocaea pyracanthae is of economic importance. The fungus received no attention in Pakistan and some other parts of the world. The current study is focused on the symptomatology of this disease and the etiology of the fungus. During extensive surveys of loquat orchards in 2013 heavy inf

2. Avaliação de acessos de Stylosanthes spp. em relação à antracnose, em condições de campo, no Distrito Federal, Brasil.
A antracnose, doença causada pelo fungo Colletotrichum gloeosporioides, é a mais importante e disseminada doença de Stylosanthes, uma leguminosa forrageira naturalmente distribuída no Brasil. Quinze acessos e cultivares de Stylosanthes guianensis, cinco de S. capitata, três de S. macrocephala, nove de S. scabra, duas cultivares de S. seabrana e o Estilo

3. Efeito de fosfito no controle de doenças foliares de trigo in vitro e in sito
O desenvolvimento e o rendimento de grãos da cultura do trigo são influenciados por diversos fatores, entre os quais se encontram a interferência causada por patógenos presentes nas lavouras. Atualmente, a principal ferramenta de controle destes patógenos nas lavouras é o uso de constantes aplicações de fungicidas. Contudo, essa prática vem ocasiona

4. Avaliação de feridas crônicas em pacientes atendidos em Unidades Básicas de Saúde de Goiânia / Assessing of chronic wounds in outpatients treated at basic health unit in goiania
Assessing patients with chronic wounds poses a challenge to professionals and doubts still persist concerning characterization of the wound infection status. We believe that the Basic Health Units are in places of reference for the public to submit chronic wounds and should have full attendance and resolution were objectives of this study: characterizing pat

5. Atividade da superoxido dismutase, catalase, peroxidases e acumulo de H2O2 associados a infecção de um Carlavirus em soja e um Potyvirus no feijoeiro / Activity of superoxide dismutase, catalase, peroxidase and accumulation of H2O2 associated with the infection of a Carlavirus in soybean and a Potyvirus in bean
Plants defend themselves from attacks of bacteria, fungi, viruses, invertebrate and other plants. Oxidative stress is a kind of physiological response of the plant related to defense mechanisms after recognition the pathogen, which may result in disease symptoms depending on host sensitivity. In this work, plants of two varieties of soybean infected by Cowpe

6. Identificação e desenvolvimento de técnica alternativa de controle de fungos em sementes utilizadas no artesanato
Some seed samples of native plants from forestry, cerrado and savannas which are currently employed for the confection of handcrafts from several brazilian regions were valued as far as the phytosanitary aspects are concerned. The fungi overview and identification associated to the seeds as well as their symptoms were accomplished. Techniques of superficial

7. DoenÃas fÃngicas e bacterianas em algumas espÃcies de Araceae / Fungicals and bacterials diseases in some Araceae species
Among the cultivated tropical ornamental plants, those belonging to the Araceae family are among the most important ones, because of its unique features such as beauty, durability, exoticity of forms and high acceptance in the international market. However, plant pathogens, such as fungi and bacteria, can damage inflorescence and shoot quality, consequently

8. Immunohistochemical demonstration of TGF-ß and decorin in paracoccidioidal granulomas
Different patterns of granulomas have been observed in 6- to 8-week-old mice after ip inoculation with 5 x 10(6) yeast cells of Paracoccidioides brasiliensis. Transforming growth factor-ß (TGF-ß) is a cytokine that has been shown to participate in fibrosis and granuloma formation; its activities seem to be modulated by the small proteoglycan decorin. In th

9. Elicitation of Necrosis in Vigna unguiculata Walp. by Homogeneous Aspergillus niger Endo-Polygalacturonase and by α-d-Galacturonate Oligomers 1
Endo-polygalacturonase (PG) was purified from a commercial preparation of Aspergillus niger pectinase by means of carboxymethylcellulose chromatography, preparative isoelectric focusing, and gel permeation through Sephadex G-50. The enzyme was electrophoretically homogeneous and consisted of a single polypeptide chain with a molecular weight of 33,500. The e

10. PCR Assays That Identify the Grapevine Dieback Fungus Eutypa lata
Eutypa lata is the causal fungal agent of Eutypa dieback, a serious grapevine necrotic disease. The erratic and delayed (1 to 2 months) appearance of characteristic conidia on culture media and the presence of numerous microorganisms in decaying wood make it difficult either to identify or to detect E. lata in grapevine wood samples. We designed six pairs of

11. Sfp-Type 4′-Phosphopantetheinyl Transferase Is Indispensable for Fungal Pathogenicity[W]
In filamentous fungi, Sfp-type 4′-phosphopantetheinyl transferases (PPTases) activate enzymes involved in primary (α-aminoadipate reductase [AAR]) and secondary (polyketide synthases and nonribosomal peptide synthetases) metabolism. We cloned the PPTase gene PPT1 of the maize anthracnose fungus Colletotrichum graminicola and generated PPTase-deficient mut

12. Activation of an AP1-Like Transcription Factor of the Maize Pathogen Cochliobolus heterostrophus in Response to Oxidative Stress and Plant Signals
Redox sensing is a ubiquitous mechanism regulating cellular activity. Fungal pathogens face reactive oxygen species produced by the host plant's oxidative burst in addition to endogenous reactive oxygen species produced during aerobic metabolism. An array of preformed and induced detoxifying enzymes, including superoxide dismutase, catalases, and peroxidases
