ABSTRACT
This study was conducted at the Agriculture College University of Karbala, Iraq to isolate and morphologically and molecularly diagnose thirteen Cladosporium isolates collected from tomato plant residues present in desert regions of Najaf and Karbala provinces, Iraq. We diagnosed the obtained isolates by PCR amplification using the ITS1 and ITS4 universal primer pair followed by sequencing. PCR amplification and analysis of nucleotide sequences using the BLAST program showed that all isolated fungi belong to Cladosporium sphaerospermum. Analysis of the nucleotide sequences of the identified C. sphaerospermum isolates 2, 6, 9, and 10 showed a genetic similarity reached 99%, 98%, 99%, and 99%, respectively, with those previously registered at the National Center for Biotechnology Information (NCBl). By comparing the nucleotide sequences of the identified C. sphaerospermum isolates with the sequences belong to the same fungi and available at NCBI, it was revealed that the identified C. sphaerospermum isolates 2, 6, 9, and 10 have a genetic variation with those previously recorded at the National Center for Biotechnology Information (NCBl); therefore, the identified sequences of C. sphaerospermum isolates have been registered in GenBank database (NCBI) under the accession numbers MN896004, MN896107, MN896963, and MN896971, respectively.
RESUMO
Este estudo foi conduzido na Agriculture College University of Karbala, Iraque, para isolar e diagnosticar morfológica e molecularmente treze isolados de Cladosporium coletados de resíduos de plantas de tomate presentes nas regiões desérticas das províncias de Najaf e Karbala, no Iraque. Diagnosticamos os isolados obtidos por amplificação por PCR usando o par de primers universais ITS1 e ITS4 seguido de sequenciamento. A amplificação por PCR e a análise de sequências de nucleotídeos usando o programa BLAST mostraram que todos os fungos isolados pertencem a Cladosporium sphaerospermum. A análise das sequências de nucleotídeos dos isolados 2, 6, 9 e 10 de C. sphaerospermum identificados mostrou similaridade genética de 99%, 98%, 99% e 99%, respectivamente, com aqueles previamente registrados no National Center for Biotechnology Informações (NCBl). Ao comparar as sequências de nucleotídeos dos isolados de C. sphaerospermum identificados com as sequências pertencentes aos mesmos fungos e disponíveis no NCBI, foi revelado que os isolados 2, 6, 9 e 10 de C. sphaerospermum identificados têm variação genética com aqueles anteriormente registrados no National Center for Biotechnology Information (NCBl). Portanto, as sequências identificadas de isolados de C. sphaerospermum foram registradas no banco de dados GenBank (NCBI) sob os números de acesso MN896004, MN896107, MN896963 e MN896971, respectivamente.
