In Korea, Japanese chestnut trees (Castanea crenata Sieb. and Zucc.) showing symptoms indicative of witches' broom disease, including abnormally small leaves and yellowing of young leaves, were examined. Since the symptoms were suggestive of a phytoplasma infection, tissues were assayed for phytoplasmas by PCR analysis using a pair of universal primers that amplify a 1.4-kbp phytoplasma 16S rDN...

The paper Broom & Rychtář (2008) analytically investigated the probability for mutants to fixate in an otherwise uniform population on two types of heterogeneous graphs (lines and stars) by evolutionary dynamics. The main motivation for concentrating on those two types of graphs only was the potentially exponential size of the system of linear equations (see equation (1.1) below) yielding the f...

Hyperspectral sensors mounted in unmanned aerial vehicles offer new opportunities to explore high-resolution multitemporal spectral analysis remote sensing applications. Nevertheless, the use of hyperspectral data still poses challenges mainly postprocessing correct from high geometric deformation images. In general, acquisition high-quality imagery is achieved through a time-consuming and comp...

Scotch broom (Cytisus scoparius (L.) Link) is a highly competitive, nonnative, leguminous shrub species of major concern in coast Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) forests the Pacific Northwest that has potential to impact long-term soil productivity. We conducted bioassay assess for legacy effects on soils (e.g., nutrient effects, seedbank, etc.) following remov...

This study was performed to examine the possibility of Er:YAG laser for dentine hypersensitivity treatment using a novel laser probe; broom-type probe. The morphological change of dentinal tubules of bovine dentine plate after low power laser irradiation (5 or 10 mJ/ pulse, 10 pps) or boiling was observed by SEM. Fifty teeth from 13 patients aged 31–54 years with complaint of dentine hypersensi...

Part of the Master Thesis of the first author. Universidade Federal Rural do Rio de Janeiro. Seropédica RJ. 2008. ABSTRACT Phytoplasmas can cause yield losses in numerous crops worldwide. In Brazil, phytoplasmal diseases have been reported in plant species, distributed among 29 botanical families. Chayote witches’-broom (ChWB) is reported as one of the diseases of economic importance, associate...

Witches' broom disease (WBD) is caused by the hemibiotrophic basidiomycete fungus Crinipellis perniciosa, which is one of the most important diseases of cocoa in the western hemisphere. In this study, the contents of soluble sugars, amino acids, alkaloids, ethylene, phenolics, tannins, flavonoids, pigments, malondialdehyde (MDA), glycerol, and fatty acids were analysed in cocoa (Theobroma cacao...

Witches' broom disease of acid lime greatly affects the production of Mexican lime in Iran. It is caused by a phytoplasma (Candidatus Phytoplasma aurantifolia). However, the molecular mechanisms that underlie phytoplasma pathogenicity and the mode of interactions with host plants are largely unknown. Here, high-throughput transcriptome sequencing was conducted to explore gene expression signatu...
