1. Search for sources of resistance to Meloidogyne enterolobii in commercial and wild tomatoes
RESUMO Meloidogyne enterolobii (=M. mayaguensis) é um patógeno de plantas capaz de induzir galhas e reduzir produtividade de uma vasta gama de espécies hospedeiras. Este patógeno tem sido também reportado como ameaça global para a cultura do tomateiro (Solanum lycopersicum), principalmente, por causa da sua habilidade de suplantar a resistência a algu

2. Common bean resistance expression to whitefly in winter and rainy seasons in Brazil
ABSTRACT: Whitefly Bemisia tabaci (Gennadius) biotype B is the major pest of common bean (Phaseolus vulgaris L.) in Brazil and other countries. Host plant resistance is one of the cornerstones of Integrated Pest Management (IPM), and assessment of cultivars for insect resistance is fundamental to provide farmers options for pest control. This study evaluated

3. Reaction of strawberry cultivars to root-knot and root-lesion nematodes
RESUMO Considerando a importância econômica da cultura do morangueiro no Brasil, com tendência clara de migração da produção no solo para sistemas inovadores de produção em substratos, é fundamental a avaliação das cultivares disponíveis no mercado quanto a tolerância a patógenos com potencial de infestação. Avaliou-se a resistência de oito

4. Avaliação do uso de elicitores de resistência bióticos e abióticos contra a antracnose na videira (Vitis labrusca L.)
RESUMO A antracnose da videira é uma doença causada pelo fungo Elsinoe ampelina sendo responsável por grandes danos na cultura. A proteção de plantas por meio da resistência induzida tem sido visualizada como uma importante medida de controle alternativo. Os elicitores de resistência estimulam uma série de reações no hospedeiro, para a produção d

5. Effects of temperature on the feeding behavior of Alabama argillacea (Hübner) (Lepidoptera: Noctuidae) on Bt and non-Bt cotton plants
ABSTRACT The host acceptance behavior and environmental factors as temperature affect the feeding behavior of Lepidoptera pests. Thus, they must be considered in studies about the risk potential of resistance evolution. The current study sets the differences in the feeding behavior of neonate Alabama argillacea (Hübner) (Lepidoptera: Noctuidae) larvae expos

6. Translational control in plant antiviral immunity
Abstract Due to the limited coding capacity of viral genomes, plant viruses depend extensively on the host cell machinery to support the viral life cycle and, thereby, interact with a large number of host proteins during infection. Within this context, as plant viruses do not harbor translation-required components, they have developed several strategies to s

7. Insilico Analysis of Phytoconstituents from Allium sativum as Potential Inhibitors of Inha in Mycobacterium tuberculosis
ABSTRACT Tuberculosis is leading cause of death among the global bacterial infections. The main causative for tuberculosis is Mycobacterium tuberculosis, which will survive in its host human being for decades in latent or chronic levels. In addition, the late multidrug resistance at a disturbing rate accompanies the appearance of tuberculosis. The quick spre

8. Phytochemicals and antimicrobial potentials of mahogany family
Drug resistance to human infectious diseases caused by pathogens lead to premature deaths through out the world. Plants are sources for wide variety of drugs used for treating various diseases. Systematic screening of medicinal plants for the search of new antimicrobial drug candidates that can inhibit the growth of pathogens or kill with no toxicity to host

9. Silicon reduces bacterial speck development on tomato leaves
This study aimed to evaluate the effect of silicon (Si) on the resistance of tomato plants (cv. Santa Clara) to bacterial speck, caused by Pseudomonas syringae pv. tomato (Pst). Tomatoes were grown in soil without calcium silicate (control), in soil without calcium silicate and sprayed with Supa Sílica® (2 mL/L) (SS) and in soil with calcium silicate (0.16

10. Defense responses to Meloidogyne exigua in resistant coffee cultivar and non-host plant
The resistance of coffee plants to Meloidogyne exigua is conferred by the gene Mex-1. However, the mechanisms of resistance still need to be clarified. Therefore, the penetration, development and reproduction of two populations of M. exigua (M1, isolated from the coffee plant and M2, from rubber tree) in susceptible (Coffea arabica 'Catuai') and resistant (C

11. Resposta de genótipos de citros à leprose e variabilidade genética da ORF p29 do vírus da leprose dos citros C (CiLV-C) / Response of citrus genotypes to leprosis and genetic variability of ORF p29 from Citrus leprosis virus C (CiLV-C)
Viruses have, potentially, broad genetic variability because of their need to adapt to several changes that they are exposed to. Therefore, genetic variability is essential for their survival; it is the first step to adapt to a new host, to break resistance down, to change symptoms and virulence, which justifies the interest in studies in this area. These st

12. Analysis of 16S rRNA and mxaF genes reveling insights into Methylobacterium niche-specific plant association
The genus Methylobacterium comprises pink-pigmented facultative methylotrophic (PPFM) bacteria, known to be an important plant-associated bacterial group. Species of this group, described as plant-nodulating, have the dual capacity of producing cytokinin and enzymes, such as pectinase and cellulase, involved in systemic resistance induction and nitrogen fixa
