Biochemical changes during the development of witches' broom: the most important disease of cocoa in Brazil caused by Crinipellis perniciosa.
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...
متن کاملTranscriptomic Analysis of Paulownia Infected by Paulownia Witches'-Broom Phytoplasma
Phytoplasmas are plant pathogenic bacteria that have no cell wall and are responsible for major crop losses throughout the world. Phytoplasma-infected plants show a variety of symptoms and the mechanisms they use to physiologically alter the host plants are of considerable interest, but poorly understood. In this study we undertook a detailed analysis of Paulownia infected by Paulownia witches'...
متن کاملLong Non-Coding RNAs Responsive to Witches’ Broom Disease in Paulownia tomentosa
Paulownia witches’ broom (PaWB) disease caused by phytoplasmas is a fatal disease that leads to considerable economic losses. Long non-coding RNAs (lncRNAs) have been demonstrated to play critical regulatory roles in posttranscriptional and transcriptional regulation. However, lncRNAs and their functional roles remain poorly characterized in Paulownia. To identify lncRNAs and investigate their ...
متن کاملIdentification of Genes Related to Paulownia Witches’ Broom by AFLP and MSAP
DNA methylation is believed to play important roles in regulating gene expression in plant growth and development. Paulownia witches' broom (PaWB) infection has been reported to be related to gene expression changes in paulownia plantlets. To determine whether DNA methylation is associated with gene expression changes in response to phytoplasma, we investigated variations in genomic DNA sequenc...
متن کاملSearching for active mobile genetic elements in dsRNA fraction of Pinus sylvestris having witches broom abnormalities
The most common type of coniferous mobile genetic elements are retrotransposons. Despite of their early positive impact on evolution of modern coniferous species they can have a significant negative impact for Forestry and breeding. Breaking genomic structural integrity mobile elements can cause phenotypic defects of plants. In this regard, the study of the diversity of coniferous mobile geneti...
