Citrus canker and Huanglongbing (HLB) are citrus diseases that represent a serious threat to the citrus production worldwide and may cause large economic losses. In this work, we combined fluorescence imaging spectroscopy (FIS) and a machine learning technique to discriminate between these diseases and other ordinary citrus conditions that may be present at citrus orchards, such as citrus scab ...

UNLABELLED SUMMARY The rapid global re-emergence of Fusarium head blight disease of wheat and barley in the last decade along with contamination of grains with mycotoxins attributable to the disease have spurred basic research on the fungal causal agent. As a result, Fusarium graminearum quickly has become one of the most intensively studied fungal plant pathogens. This review briefly summarize...

A naïve (unimmunized) human semisynthetic phage display library was employed to isolate recombinant antibody fragments against the cyanobacterial hepatotoxin microcystin-LR. Selected antibody scFv genes were cloned into a soluble expression vector and expressed in Escherichia coli for characterization against purified microcystin-LR by competition enzyme-linked immunosorbent assay (ELISA). The ...

Major histocompatibility complex (MHC) class I genes encode cell surface molecules that bind and present immunogenic peptides to cytolytic T lymphocytes. We have developed a model using the MHC (Scab) of tassel-eared squirrels, Sciurus aberti, to investigate the evolution of MHC genes in subspecies that have been effectively isolated in comparable, if not identical, environments. Class I cDNAs ...

Meng, Q. X., Yin, J. F., Rosenzweig, N., Douches, D., and Hao, J. J. 2012. Culture-based assessment of microbial communities in soil suppressive to potato common scab. Plant Dis. 96:712-717. A field in East Lansing, MI, showed a decline of potato common scab compared with an adjacent potato field. To confirm that the decline was due to biological factors, the soil was assayed. In the greenhouse...

Humanized antibodies vary and have certain effects, but they are expensive and require repeated administration. We developed cells which constantly express a humanized antibody, and we performed anticancer humanized antibody therapy involving cell transplantation. Genes with the same amino acid sequence as that of the variable region of trastuzumab (Herceptin) as the humanized anti-HER2 monoclo...

The genus Streptomyces includes several phytopathogenic species that cause common scab, a devastating disease of tuber and root crops, in particular potato. diversity scab is unknown. Likewise, the genomic context necessary for bacteria to incite symptom development not fully characterized. Here, we phenotyped sequenced genomes five strains from poorly studied lineage. These form new species-le...

Molecular markers derived from resistance gene analogs of HcrVf2, the first apple resistance gene cloned, may pave the way to the cloning of additional apple scab resistance genes. The Malus xdomestica 'Florina' (Vf) bacterial artificial chromosome (BAC) genomic library was screened by hybridization using HcrVf2 as a probe. Positive BAC clones were assembled into contigs and microsatellite mark...

A range of possible substitutes for copper-based fungicides for control of apple scab (Venturia inaequalis) in organic growing were tested in laboratory and growth chamber experiments in the Danish project StopScab (2002-2004). Eighteen crude plant extracts, 19 commercial plant-based products and 6 miscellaneous compounds were tested for their ability to reduce scab symptoms on apple seedlings....
