Abstract

Sexual reproduction of fungi is governed by the mating type (MAT) locus. Because two alternate forms (alleles) are completely dissimilar sequences and encoding different transcription factors, this locus is structurally unusual, yet they occupy the same chromosomal position. Genomic analyses facilitate the definition of MAT locus sequences in many species, so the knowledge of MAT locus structure and evolution has been significantly advanced in recent years. This important genomic feature has been studied most extensively in the largest phylum of the fungi, Ascomycota, which is the largest group of the plant pathogenic fungi. In this article we discuss the different aspects of mating type genes and their structure and organization in Ascomycota. Knowledge on the mating type genes may provide a great assistance to understanding the potential of phytopathogenic fungi for sexual cycle and consequently on genetic diversity in fungal populations. The proper data on sexual reproduction and genetic diversity of phytopathogenic fungi might be useful in different aspects of plant disease management.

Abstract

Bakhshi M. 2018. Important criteria for identification of the Cercospora species. Plant Pathology Science 7(1):1-14.

Species of the genus Cercospora are important plant pathogenic fungi with worldwide distribution. They are often associated with leaf spots, occurring on a wide range of hosts in almost all major families of dicots, most monocot families, and even some gymnosperms and ferns. Different characteristics, such as morphology, toxin production and host specificity were used to distinguish species. New research findings have shown that a polyphasic approach, combining morphological, ecological and phylogenetic species concepts, which are discussed in this article, proved the most effective method to distinguish species of the genus Cercospora. Accurate identification of these plant pathogens is the first step to adopt the appropriate management strategies for their disease control. Therefor, it is recommended that, in order to accurate identification of the species of the genus Cercospora, they should be studied and reviewed on the basis of these criteria.

Abstract

Bakhshi. M. 2019. A revision on the taxonomy of the genus Pseudocercospora. Plant Pathology Science 8(1):1-14. DOI: 10.2982/PPS.8.1.1.
 
 Pseudocercospora species are plant pathogenic fungi occurring on a wide range of herbaceous and woody plants. Since its early description of the genus, its taxonomy has always been challenging. In recent years, Multi-gene DNA sequence data have provided significant information on the accurate taxonomy of the genus Pseudocercospora. These data revealed that the species of Pseudocercospora are polyphyletic and evolved in more than one approach within family Mycosphaerellaceae, order Capnodiales, class Dothideomycetes, phylum Ascomycota. Also those species from different geographic regions but with the same morphology, symptomatology and host range, may reside in different phylogenetic clades. Accurate identification of the plant disease agent is the first step to adopt the appropriate management strategies of the diseases related to these plant pathogens. Key features of morphology and new genetic data for identifying the species of the genus are described in this article.
