The Phomopsis is a genus of imperfect plant pathogenic fungus whose hosts comprise several species in different regions of the world, such as grapes, soybean, acacia, hollyhock, velvetleaf, and several other plants. In this study, samples collected from hollyhock, velvetleaf, purple bauhinia, and acacia plants suspected to be infected with Phomopsis fungi. Samples were culture...

aphids are among important agricultural pests. the pest's evolutionary tendency towards a loss of taxonomically useful characteristics, as well as morphological plasticity due to host type and as a result of environmental factors, make a morphological identification of aphids difficult, whereas exact identification is indispensable for managment of these pests. thus, modern identification ...

In this study molecular identification of four species of Gastropoda have been studied based on mitochondrial genes, COI and 16S rRNA in the present work for the first time in the northern rocky coastal zones of Persian Gulf during years 2013 and 2014. Planaxis sulcatus، Cerithidea cingulata، Siphonaria savignyi and Onchidium peronii Identified. After morphological identification, DNA extractio...

Amirmijani, A. M. 2019. Important characters in identification of Cladosporium spp. Plant Pathology Science 8(1):50-59. DOI: 10.2982/PPS.8.1.50. The genus Cladosporium is one of the largest genera of fungi. Its species live in different ways: as plant pathogens, as saprobes in the soil or on decaying plant materials, or as hyperparasitic on other fungi. Morphological characteristics of con...

Ticks are important acarina that infest animals. They are obligatory blood sucker arthropods which economically impact cattle industry by reducing weight gain and production. Moreover, they are important vectors of viral, bacterial, rickettsial and parasitic pathogens infecting humans and animals. In view of the importance of Hyalomma anatolicum anatolicum in pathogen transmission, including Th...

Recent studies suggested that accurate species identification in the tropical anguillid eels based on morphological examination requires confirmation by molecular genetic analysis. Previous studies found that two tropical anguillid eels, Anguilla bicolor bicolor and A. bengalensis bengalensis, were found in peninsular Malaysia (West Malaysia) based on morphological and molecular genetic analyse...

We discuss two types of asymmetry between wordforms and their (morphological) characteristics, namely (morphological) variants and homographs. We introduce a concept of multiple lemma that allows for unique identification of wordform variants as well as ‘morphologicallybased’ identification of homographic lexemes. The deeper insight into these concepts allows further refining of morphological d...
