Arabinogalactan proteins: decoding the multifaceted roles in plant reproduction
Silva, Jessy; Moreira, Diana; Ferreira, Maria João; Pereira, Ana Marta; Pereira, Luís Gustavo; Coimbra, SílviaArabinogalactan proteins (AGPs) are highly glycosylated cell wall proteins essential for plant growth and reproduction. AGPs are extensively decorated with arabinogalactan polysaccharides, composed primarily of arabinose and galactose, along with minor sugars such as glucuronic acid, fucose, and rhamnose. Their glycosylation patterns and glycosylphosphatidylinositol anchor enable interactions with receptors, mo...
Expression-based and co-localization detection of arabinogalactan protein 6 and...
Costa, Mário; Nobre, Margarida Sofia; Becker, Jörg D; Masiero, Simona; Amorim, Maria Isabel; Pereira, Luís Gustavo; Coimbra, SílviaArabinogalactan proteins (AGPs) are cell wall proteoglycans that have been shown to be important for pollen development. An Arabidopsis double null mutant for two pollen-specific AGPs (agp6 agp11) showed reduced pollen tube growth and compromised response to germination cues in vivo. A microarray experiment was performed on agp6 agp11 pollen tubes to search for genetic interactions in the context of pollen tube...
Asymptomatic infection in family contacts of patients with human visceral leish...
Oliveira, Ana Lúcia Lyrio de; Paniago, Anamaria Mello Miranda; Sanches, Marcos Antônio; Dorval, Maria Elizabeth Moraes Cavalheiros; Oshiro, Elisa TeruyaThe Brazilian city of Três Lagoas, Mato Grosso do Sul State, has experienced an urban outbreak of visceral leishmaniasis since 2000. In 2002, due to the increase in the number of cases, 46 families with cases of visceral leishmaniasis were studied to verify the prevalence of asymptomatic infection in household contacts. Indirect immunofluorescence and ELISA showed a 36.4% positive infection rate. There were no ...
