Volume 6, Issue 2 (9-2017)
Abstract

Vasebi Y., Buroon S. and  Faghihi M. M. 2017. Common pathogenic agents of plant and human. Plant Pathology Science 6(2):78-88.

Some plant pathogens are also serious threats to human health. Pathogenic fungi from the genera Alternaria, Aspergillus, Bipolaris, Cladosporium, Claviceps, Fusarium, Paecilomyces and Exserohilum, and some bacteriaa genera including Burkholderia, Enterobacter, Enterococcus, Escherichia, Erwinia, Pantoea, Pseudomonas, Salmonella, Serratia and Xanthomonas can cause harmful diseases in human. Diseases caused by these microorganisms in plants and human are described here and some researches to identify them on raw fruits and vegetables are suggested.

Abstract
Nasiri M, Faghihi M M (2022) Bacterial mosaic disease of wheat. Plant Pathology Science 11(2):103-111.    Doi: 10.2982/PPS.11.2.103

Bacterial mosaic of wheat is caused by the gram positive bacterium Clavibacter tessellarius. The symptoms of the disease are uniformly distributed small chlorotic spots with mosaic pattern on the entire leaf surface resemble those symptoms of nutrient deficiencies and some viral diseases, and it may be difficult to determine. Due to the seed-borne nature of the disease, use of healthy and certified pathogen free seeds is the most important strategy for managing this disease. The wheat bacterial mosaic has been reported in wheat fields in several provinces of Iran and it seems to be widespread in different wheat growing areas. In order to better understand the disease, its various aspects including the symptoms, pathogen biology and its host ranges, and management of the disease are reviewed in this article.

Introduction: Huanglongbing or Fruit Greening is one of the major citrus diseases in Iran that has spread to most of the country's citrus growing provinces. In this study, the prevalence trend of the disease in seven provinces was investigated and analyzed. Materials and Methods: Citrus orchards in Sistan-Balochestan, Hormozgan, Bushehr, Khuzestan, Fars, Kerman and Mazandaran provinces were visited and samples suspected of having this disease were collected, in 2007-2009 and 2017-2019 years. After DNA extraction from the samples, the PCR test was performed using the specific primers OI1/OI2c and A2/J5. Results: It was found that the percentage of infected specimens, infected areas and number of hosts of Candidatus Liberibacter asiaticus, the causative agent of this disease, has increased over this period. At the end of this period, some samples of oranges, tangerines, grapefruits, bitter oranges, Lisbon lemons and Mexican limes were obtained from the provinces: Kerman, Hormozgan, Sistan-Baluchestan, and Fars were infected with the disease. Conclusion: The study of the disease during these years showed that: the infected areas and the host range of the disease have expanded a lot during this period, and the spread of the disease in citrus cultivation areas in the south of the country has been with a gentle slope. The reduction of the disease-carrying psyllium population during these years seems to have been effective in slowing down the spread of the disease.
