Acer pseudoplAtAnus L., Acer plAtAnoides L. and BetulA pendulA Roth. as bioindicatoRs of uRban poLLution in sofia
Acer pseudoplatanus L., Acer platanoides L. and Betula pendula Roth. have been studied under the urban pollution in Sofia during 3 years period. The aim of the study was, by statistical multifactorial analysis, to assess the value changes in morphological parameters of species under air pollution and potential for species usage as bioindicators in observed regions. The statistical analysis incl...
متن کاملQualitative and Quantitative Changes in Proteins in Acer Platanoides L. Seeds during Maturation
Maturation of Norway maple (Acer platanoides L.) seeds produces deep physiological dormancy and resistance to desiccation. This study used two-dimensional electrophoresis to investigate the protein products of genes activated during the complex developmental process of maturation. Qualitative and quantitative changes in protein composition during maturation were tracked in this species. The mos...
متن کاملEffect of gibberellic acid on germination capacity and emergence rate of Sycamore maple (Acer pseudoplatanus L.) seeds
Seedlots of sycamore maple (Acer pseudoplatanus L.) originating from three different provenance regions were collected in autumn 2012. The seed quality, namely vitality and germination rate, was assessed according to Czech conventions. There were four replications within each seedlot, i.e. twelve treatments altogether for each experimental variant. The effect of gibberellic acid on germination ...
متن کاملProteomic Analysis of Embryogenesis and the Acquisition of Seed Dormancy in Norway Maple (Acer platanoides L.)
The proteome of zygotic embryos of Acer platanoides L. was analyzed via high-resolution 2D-SDS-PAGE and MS/MS in order to: (1) identify significant physiological processes associated with embryo development; and (2) identify changes in the proteome of the embryo associated with the acquisition of seed dormancy. Seventeen spots were identified as associated with morphogenesis at 10 to 13 weeks a...
متن کاملExpression of Amyloplast and Chloroplast DNA in Suspension-Cultured Cells of Sycamore (Acer pseudoplatanus L.).
Green mutant cells of sycamore (Acer pseudoplatanus L.), which had been selected by mutagenic treatment of the white wild type, grow photoheterotrophically in auxin-depleted culture medium. In contrast to the wild-type cells, mutant cells exhibit photosynthetic O(2)-evolution activity during their growth coincident with increases of (a) chlorophyll, (b) protein, and (c) ribulose-1,5-bisphosphat...
