Micropropagation of Pluchea sagittalis (Lam.) Cabrera

Rapid micropropagation of Geodorum densiflorum (Lam) Schltr. in liquid culture.

Technique for rapid mass propagation of Geodorum densiflorum (Lam)Schltr. has been developed by using thin sections of stems of in vitro regenerated plantlets as explant source. Thin sections of stems (1.0-1.5 mm) when cultured in modified liquid and semisolid Knudson C (KnC) medium produced 1.8 and 1.2 protocorm like bodies (PLBs) per explant respectively. Peptone (2 g l-1) was effective in pr...

Alterations in the mitotic index of Allium cepa induced by infusions of Pluchea sagittalis submitted to three different cultivation systems.

We evaluated the antiproliferative effect of infusions from Pluchea sagittalis using the Allium cepa test. Infusions in three concentrations (2.5, 5, and 25 g dm-3) of leaves cultivated in three environments (in vitro, acclimatized growth chamber, and field) were used. Six onion bulbs were used for each of the eight treatments, and the mitotic index was obtained from 6000 cells per treatment. I...

El cáncer de colon es una enfermedad frecuente que puede ser esporádica o familiar. La inactivación del gen supresor de tumores APC (adenomatous polyposis coli) se ha encontrado en más del 80% de los casos descritos de tumores colorrectales, apareciendo como una alteración temprana durante el desarrollo del pólipo adenomatoso. La inactivación del gen APC no es únicamente crítica en el proceso d...

bution of host genetic factors (the FUT2 genotype in particular) on differences in the gut microbiota between patients with Crohn disease and healthy individuals. Thus, an intimate relation between host genetics and bioactive components is expected and should be linked to both infant microbiota colonization and immune system development. The process of microbial colonization of the infant’s gut...
