1. Effect of Inoculation of Pineapple Plantlets with Arbuscular Mycorrhizal Fungi Obtained from Different Inoculum Sources Multiplied by the On-Farm Method
ABSTRACT The production of inoculum from arbuscular mycorrhizal fungi (AMF) at a large scale and low cost is essential for establishing methods to assist in producing pineapple plantlets with high nutritional and phytosanitary quality. However, this objective is difficult to accomplish because of the biotrophic nature of these fungi. The on-farm multiplicati

2. Compatibility and incompatibility in hyphal anastomosis of arbuscular mycorrhizal fungi
ABSTRACT: Arbuscular mycorrhizal fungi (AMF), which live in symbiosis with 80 % of plants, are not able to grow when separated from their hosts. Spore germination is not host-regulated and germling growth is shortly arrested in the absence of host roots. Germling survival chances may be increased by hyphal fusions (anastomoses), which allow access to nutrien

3. The glyceraldehyde-3-phosphate dehydrogenase gene of Moniliophthora perniciosa, the causal agent of witches' broom disease of Theobroma cacao
This report describes the cloning, sequence and expression analysis of the glyceraldehyde-3-phosphate dehydrogenase (GAPDH) gene of Moniliophthora perniciosa, the most important pathogen of cocoa in Brazil. Southern blot analysis revealed the presence of a single copy of the GAPDH gene in the M. perniciosa genome (MpGAPDH). The complete MpGAPDH coding sequen

4. Caracterization of a thaumatin-like gene expressed by Moniliophthora Perniciosa fungus, the causative agent of cacao Whiches Broom disease / Caracterização de um gene similar a taumatina expresso pelo fungo causador da Vassoura de bruxa, Moniliophthora perniciosa
Moniliophthora perniciosa is a phytopatogen that has economical importance in Brazil, particularly in the south of Bahia, because this fungus causes the disease in cacao known as Witches Broom disease. This fungus is a hemibiotrofic pathogen that has two distinct stages: a biotrophic (or parasitic) and a necrotrophic (or saprotrophic). The database generated

5. 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

6. Contribuição do tratamento de sementes de soja (Glycine max L. Merril) com fungicidas no manejo da ferrugem asiática / Contribution of soybean (Glycine max L. Merril) seed treatment with fungicides in the management of asian rust
Seed treatment has as traditional objective to eradicate or to reduce fungi associated with seeds and to protect them from soilborne pathogens. Some diseases that occur in the aerial part of plants may be managed through seed treatment with systemic products. This kind of control has been used for many years, aiming the control of biotrophic fungi in rice an

7. Caracterização bioquimica e molecular da doença vassoura-de-bruxa do cacaueiro (Theobroma cacao L.), causada pelo fungo Crinipellis perniciosa / Biochemical and molecular characterization of witches broom disease of cocoa (Theobroma cacao L.), caused by the fungus Crinipellis perniciosa
Witches? broom disease, caused by the hemibiotrophic fungus Crinipellis perniciosa, is one of the most important diseases of cocoa, causing dramatic production and economic losses. A better understanding of the cacao - C. perniciosa interaction and the processes that occur in the plant during disease progression becomes necessary in order to establish novel

9. Characterization of a novel NADP+-dependent D-arabitol dehydrogenase from the plant pathogen Uromyces fabae
We have identified and characterized a novel NADP+-dependent D-arabitol dehydrogenase and the corresponding gene from the rust fungus Uromyces fabae, a biotrophic plant pathogen on broad bean (Vicia faba). The new enzyme was termed ARD1p (D-arabitol dehydrogenase 1). It recognizes D-arabitol and mannitol as substrates in the forward reaction, and D-xylulose,

10. Medicago truncatula plants overexpressing the early nodulin gene enod40 exhibit accelerated mycorrhizal colonization and enhanced formation of arbuscules
The mutualistic symbiosis between flowering plants and arbuscular mycorrhizal fungi is extremely abundant in terrestrial ecosystems. In this symbiosis, obligately biotrophic fungi colonize the root of the host plants, which can benefit from these fungi by enhanced access to mineral nutrients in the soil, especially phosphorus. One of the main goals of r

11. The Monosaccharide Transporter Gene, AtSTP4, and the Cell-Wall Invertase, Atβfruct1, Are Induced in Arabidopsis during Infection with the Fungal Biotroph Erysiphe cichoracearum1
Powdery mildew fungi are biotrophic pathogens that form a complex interface, the haustorium, between the host plant and the parasite. The pathogen acts as an additional sink, competing with host sinks, resulting in considerable modification of photoassimilate production and partitioning within the host tissue. Here, we examine the factors that may contri

12. What Do Microbes Encounter at the Plant Surface? Chemical Composition of Pea Leaf Cuticular Waxes1
In the cuticular wax mixtures from leaves of pea (Pisum sativum) cv Avanta, cv Lincoln, and cv Maiperle, more than 70 individual compounds were identified. The adaxial wax was characterized by very high amounts of primary alcohols (71%), while the abaxial wax consisted mainly of alkanes (73%). An aqueous adhesive of gum arabic was employed to selectively sam
