Mechanisms of resistance to QoI fungicides in phytopathogenic fungi.
The major threat to crops posed by fungal diseases results in the use by growers of enormous amounts of chemicals. Of these, quinol oxydation inhibitors (QoIs) are probably the most successful class of agricultural fungicides. QoIs inhibit mitochondrial respiration in fungi by binding to the Qo site of the cytochrome bc1 complex, blocking electron transfer and halting ATP synthesis. Unfortunate...
متن کاملGenetic variability of Brazilian isolates of Alternaria alternata detected by AFLP and RAPD techniques
The Alternaria brown spot (ABS) is a disease caused in tangerine plants and its hybrids by the fungus Alternaria alternata f. sp. citri which has been found in Brazil since 2001. Due to the recent occurrence in Brazilian orchards, the epidemiology and genetic variability of this pathogen is still an issue to be addressed. Here it is presented a survey about the genetic variability of this fungu...
متن کاملA review of Alternaria alternata sensitivity.
Sensitivity to fungi is a major risk factor for the development of asthma. However, the prevalence of fungal sensitivity in asthma is not completely understood. Nonetheless upward of 80% of asthmatic patients may be sensitized to one or more fungi. Fungal exposure occurs primarily from outdoors sources, but can occur in the indoor environment as well. Assessment of fungal exposure requires a mu...
متن کاملTranscriptomic profile of tobacco in response to Alternaria longipes and Alternaria alternata infections
Tobacco brown spot caused by Alternaria fungal species is one of the most damaging diseases, and results in significant yield losses. However, little is known about the systematic response of tobacco to this fungal infection. To fill this knowledge gap, de novo assemblies of tobacco leaf transcriptomes were obtained in cultivars V2 and NC89 after the inoculation of either Alternaria longipes (A...
متن کاملCandidate Resistant Genes of Sand Pear (Pyrus pyrifolia Nakai) to Alternaria alternata Revealed by Transcriptome Sequencing
Pear black spot (PBS) disease, which is caused by Alternaria alternata (Aa), is one of the most serious diseases affecting sand pear (Pyrus pyrifolia Nakai) cultivation worldwide. To investigate the defense mechanisms of sand pear in response to Aa, the transcriptome of a sand pear germplasm with differential resistance to Aa was analyzed using Illumina paired-end sequencing. Four libraries der...
