Browning and contamination are regarded as the main constraints in plant tissue culture of Musa spp. that can hinder success propagation vitro. is caused by enzymatic reactions due to explant injury, while microbial phyllospheric, rhizospheric, endophytic microorganisms reside on, in, inside plants. When not properly addressed, they cause decreased regenerative ability, callus growth, inhibited...

BACKGROUND The purpose of this study was to determine the timing and type of surgical field contamination in 50 consecutive resections for advanced head and neck cancer with same-stage tissue reconstruction and to analyze the relationship between contamination and the surgical site infection. METHODS Swabs from the surgical field and from surgical drapes close to the field were taken every 2 ...

A major goal of global gene expression profiling in plant seeds has been to investigate the parental contributions to the transcriptomes of early embryos and endosperm. However, consistency between independent studies has been poor, leading to considerable debate. We have developed a statistical tool that reveals the presence of substantial RNA contamination from maternal tissues in nearly all ...

Fracturing quartz produces silica-based radicals on the fracture planes and generates hydroxyl radicals (.OH) in aqueous media. .OH production has been shown to be directly associated with quartz-induced cell damage and phagocyte activation in vitro. This .OH production in vitro is inhibited by desferrioxamine mesylate, an Fe chelator, indicating involvement of a Fenton-like reaction. Our objec...

Yellow sap contamination (YSC) is one of the mangosteen quality constrain in Indonesia. Calcium prominent nutrient that influence incidence yellow contamination. A research with objective to observe relationship between YSC and Ca availability soil as well plant tissue was done ten locations West Sumatra, Lampung Java provinces. Purposive random sampling method used determine site locations. Th...

The presence of fungal and bacterial contamination in vitro propagation is a determinant the culture establishment. biocide PPM (Plant Preservative Mixture™) has been utilized to control contamination. According manufacture’s label, it heat-stable, broad-spectrum product, non-selective, that affects directly microorganisms without causing damage plant cells. purpose this study was evaluate infl...
