To study the toxic mechanisms of lead (Pb) in plants, the effects of Pb on the morphology and structure of the nucleolus in root tip meristematic cells of Allium cepa var. agrogarum L. were investigated. Fluorescence labeling, silver-stained indirect immunofluorescent microscopy and western blotting were used. Fluorescence labeling showed that Pb ions were(More)
Masson pine (Pinus massoniana) is one of the most important timber species with adaptable, fast growing, versatile advantages in southern China. Despite considerable research efforts, the cellular and molecular mechanisms of A1 toxicity and resistance in P. massoniana are still poorly understood. The effects of Al on uptake and translocation of Al and other(More)
To characterize a novel α-glucosidase from the thermophilic fungus Malbranchea cinnamomea. The enzyme was purified to homogeneity with purification fold of 40 and a recovery of 7.2 %. It was a monomer with molecular mass of 65.7 kDa on SDS-PAGE. It was optimally active at pH 6 and 50 °C (measured over 10 min) and exhibited a wide range of substrate(More)
In order to further understand the toxic effects of Pb on root tip cells of Allium cepa var. agrogarum, root growth, Pb uptake, cell division, DNA damage and MT cytoskeleton were investigated. Fluorescence labeling; Carbol Fuchsin-staining; indirect immunofluorescent microscopy; comet assay. Pb ions entered A. cepa root meristem cells within hours of(More)
