1. Interação molecular planta-nematóide.
ABSTRACT: The endoparasitic sedentary phytonematodes of genera Heterodera, Globodera (known as cyst nematodes, CN) and Meloidogyne (the root-knot nematodes, RKN) are major crop phytopathogens, causing estimated losses of US$ 125 billion annually in the world. These plant-parasitic nematodes share some parasitism mechanisms, which ensure host-tissue invasion

2. DependÃncia MicorrÃzica do Maracujazeiro-Doce (Passiflora alata) e Comportamento de Mudas Micorrizadas ao Parasitismo do NematÃide das Galhas Meloidogyne incognita raÃa 1 / DependÃncia MicorrÃzica do Maracujazeiro-Doce (Passiflora alata) e Comportamento de Mudas Micorrizadas ao Parasitismo do NematÃide das Galhas Meloidogyne incognita raÃa 1
Objetivando estudar esta associaÃÃo especÃfica foram realizados trÃs experimentos para estimar a dependÃncia micorrÃzica (DM) do maracujazeiro doce (1) e avaliar o efeito do FMA no parasitismo do nematÃide Meloidogyne incognita raÃa 1 inoculado durante o transplantio (2) e apÃs o estabelecimento do FMA (3). Para (1) o delineamento foi inteiramente c

3. Induction Patterns of an Extensin Gene in Tobacco upon Nematode Infection.
When sedentary endoparasitic nematodes infect plants, they induce complex feeding sites within the root tissues of their host. To characterize cell wall changes induced within these structures at a molecular level, we studied the expression of an extensin gene (coding for a major structural cell wall protein) in nematode-infected tobacco roots. Extensin gene

4. Induction of phloem unloading in Arabidopsis thaliana roots by the parasitic nematode Heterodera schachtii.
Phloem unloading of both the fluorescent probe carboxyfluorescein (CF) and 14C-labeled solutes was induced in Arabidopsis thaliana L. roots by the parasitic nematode Heterodera schachtii Schmidt. Confocal laser scanning microscopy demonstrated that anomalous unloading of CF from the sieve element companion cell complexes occurred specifically into the syncyt

5. Manipulation of Auxin Transport in Plant Roots during Rhizobium Symbiosis and Nematode Parasitism
The plant rhizosphere harbors many different microorganisms, ranging from plant growth–promoting bacteria to devastating plant parasites. Some of these microbes are able to induce de novo organ formation in infected roots. Certain soil bacteria, collectively called rhizobia, form a symbiotic interaction with legumes, leading to the formation of nitrogen-fi
