  • Occurrence, Genetic Variability, and Symptomatology of Potyvirus citrulli (Watermelon Mosaic Virus) Infecting Cucurbits in Iraq
    Hayder R. Alinizi, Haider H. Nawar, Nawres A. Al-Kuwaiti
    Research in Plant Disease, 2026
    During 2022-2023 growing season, 11 Iraqi provinces were surveyed for the prevalence of Potyvirus citrulli in cucurbit fields. Thirty-six symptomatic samples were screened using reverse transcription-polymerase chain reaction and three sets of potyviral specific primers targeting the partial helper component proteinase (HCPro), cylindrical inclusion (CI), and nuclear inclusion b protein (Nib) genes within P. citrulli genome. Twentynine out of 36 samples were infected with P. citrulli. Sequence comparisons of the three genomic regions revealed that 17 isolates shared 88-100% nucleotide identity with isolates from National Center for Biotechnology Information indicating they were genetically variable. Phylogenetic analyses confirmed the variation of HC-Pro, CI, and NIb separating the 17 isolates within P. citrulli group. The high nucleotide sequence identity to existing isolates suggests successful introduction enabling to overcome and adaptation of those isolates to the Iraqi environment. Inoculation tests revealed variable symptoms, when zucchini plants exhibited the most severe symptoms compared to watermelon and cucumber plants. These findings highlight that P. citrulli can be a serious threat to cucurbit cultivation in Iraq.

  • Molecular Detection and Antiserum Preparation of Begomoviruses Infecting Zucchini Squash in Iraq
    S. Owaid, N. Al-Kuwaiti
    Iop Conference Series Earth and Environmental Science, 2025
    Begomoviruses infecting zucchini squash were investigated. Leaf samples were collected from zucchini squash growing areas in Baghdad (Jhadryaa and Yusufiyah), Babylon (Jibela and Mahmudiyah) and Diyala (Khan Bani Saad) Provinces. Samples were screened for the presence of begomoviruses using polymerase chain reaction (PCR) and Deng genus specific primers. Sixteen out of 40 samples were begomovirus positive. Sequence analysis confirmed the detection of Tomato leaf curl Palampur virus (TLCPALV) Begomovirus solanumpalampurense, Squash leaf curl virus (SLCuV) B. cucurbitapeponis and Tomato yellow leaf curl virus (TYLCV) B. coheni in zucchini squash and Datura stramonium samples. Co-infections of B. solanumpalampurense, and B. cucurbitapeponis, B. solanumpalampurense and B. coheni were detected in most samples suggesting begomovirus mixed infections are common in the investigated zucchini squash fields. Datura stramonium can be an alternatives host to B. solanumpalampurense and B. coheni. Total protein extracted from begomovirus infected samples were injected into lab rats to prepare begomovirus specific antibodies. The resultant polyclonal antibodies were labeled using horseradish peroxidase and enzyme linked immune assay (ELISA) was performed. Antibodies prepared could detect begomovirus in infected samples scoring 1.247 highest absorbance value at 405 nm compared to 1.198 of slandered TYLCV antigen. Proteins extracted from begomovirus co-infected tissues can be used to immunize rats for the production of beganovirus specific polyclonal antibodies.
  • MOLECULAR CHARACTERIZATION OF CUCUMBER MOSAIC VIRUS SUBGROUP IB IN IRAQ
    Ahmed K. Ali, Ibrahim A. Ahmed, Nawres A. Alkuwaiti
    Plant Protection, 2023
    Cucumber mosaic virus (CMV) isolate was identified on cucumber and cowpea plants exhibiting mosaic, mottling and leaf distortion in local fields in the province of Baghdad. The virus was characterized by reverse transcriptase polymerase chain reaction (RT-PCR) using coat protein (CP) gene specific primers. Comparison of the coat protein sequence revealed up to 98-99% nucleotide identity with known CMV isolates. Phylogenetic analysis based on coat protein gene sequence clustered the Iraqi CMV isolate with members of subgroup IB. To the best of our knowledge, this is the first report of CMV subgroup IB in Iraq.

    Journal of Applied Biology and Biotechnology, 2023
    A field experiment was performed to assess the susceptibility of Triticum aestivum L. var. Cham 6, Aras, and Baraka wheat local varieties, treated with Trichoderma harzianum Rifai bioagent, against seed gall infection. Anguina tritici identification was confirmed based on PCR amplification and sequence comparison of 18S small subunit ribosomal DNA. Sequence analysis showed A. tritici isolated from Waset and Kirkuk provinces shared 100% maximum nucleotide sequence identity with the equivalent GenBank sequences from Mexico (AF363107) and India (JF826516), respectively, suggesting their common origin. Field experiment revealed that T. aestivum L. var. Aras was less susceptible to seed call infection when scored 28.9% infectivity percent followed by Baraka and Cham 6 varieties which scored 29.6 and 33.1% infectivity, respectively. T. harzianum root watering treatment could decrease the disease incidence when scored 15.4, 17.5, and 19.7% compared to spraying treatment which scored 19.3, 20.8, and 22.4% infectivity, for Aras, Baraka, and Cham 6 varieties, respectively. Besides, root watering treatment reduced seed gall disease up to 46.71% compared to 33.22% for foliar spraying treatment. Thus, T. harzianum bioagent can be used as an ecofriendly nematicide alternative to control seed gall disease in Iraq.

  • First molecular confirmation of the fungus Leveillula taurica causing powdery mildew disease on sweet pepper in Iraq
    Salam Jasim Al-Hamad, Jenan Khazal, N. Al-Kuwaiti
    Archives of Phytopathology and Plant Protection, 2022
    A study was initiated to investigate powdery mildew disease on pepper during the growing season 2019/2020. Disease incidence scored 73, 85, 80 and 56% in Al-Mahmudiyah, Al-Yusufiyah and Al-Jadriya/Baghdad and Suwaira/Wasit, respectively. Morphological identification revealed L. taurica formed dimorphic conidia, lanceolate primary conidia and cylindrical to clavate secondary conidia. Conidiophores were straight, having short hyaline and unbranched baring single conidiospores. Sequence comparison of ITS region confirmed L. taurica shared 99% maximum nucleotide identity with sequences from South Korea (MH698492.1), Mexico (MG571545.1) and Australia (MT125857.1). To the best of our knowledge, this is the first molecular confirmation of L. taurica infecting pepper in Iraq.
  • Molecular characterization of viruses associated to leaf curl disease complex on zucchini squash in iraq reveals deng primer set could distinguish between new and old world begomoviruses

    Anais Da Academia Brasileira De Ciencias, 2021
    The emergence of begomoviruses has led to significant losses in vegetable production in the recent years. Squash leaf curl disease (SqLCD) is caused by begomoviruses, and the infected plants show leaf curl symptoms on zucchini squash. In this study, we characterized the begomoviruses responsible for SqLCD symptoms and economic losses in zucchini major growing area near Baghdad and Babylon provinces. PCR amplification was performed to screen for begomovirus infection using Deng (a begomovirus specific) primer set. Sequence comparison confirmed the detection of two begomoviruses; Tomato leaf curl Palampur virus (ToLCPMV) and Squash leaf curl virus (SLCuV), in symptomatic zucchini samples when shared 99.14 and 99.50% maximum nucleotide (nt) identities with coat protein CP gene, respectively. All samples collected from Baghdad/Al-Jadriya were ToLCPMV infected while those collected from Babylon/Jibela were SLCuV infected. Moreover, mixed infection of the two viruses was detected in all zucchini squash samples collected from Baghdad/Yusufiyah. Evidence is provided here of the relevance of the wild species Malva neglecta and Datura stramonium as reservoir of begomoviruses that cause epedemics of leaf curl disease in zucchini squash in Iraq. Neighbor joining (NJ) Phylogenetic analysis confirmed the relatedness when diverged virus sequences in separated groups based on CP gene. The high nt identity suggests the two begomoviruses may recently be introduced to Iraq and could be a serious threatening to squash cultivation.
  • Biodiversity and occurrence of plant viruses over four decades: Case study for Iraq
    Mustafa Adhab, Nawres Al-Kuwaiti, Rakib Al-Ani
    2021 3rd International Sustainability and Resilience Conference Climate Change, 2021
    During the past 35 years, Iraq has invested a tremendous amount of resources to develop a modern agricultural system. This effort has resulted in a leap, particularly, in cereal and vegetable production that met up to 70% of the nation's demands in 1990s. Since 2003, the percent has dropped to score 35% in the year 2010 due to political unrest. Although the agricultural system has been extremely affected in the past 15 years, farmers have been struggling to keep on their business and to contribute to the Iraqi market against high competent producers that include big agricultural neighboring countries like Turkey, Iran and Syria. However, there is another important issue tackling the production and has not been well documented in Iraq. This issue is the plant disease and viral diseases in particular, which has been a limiting factor for sustainable production of many important crops in Iraq. This article presents a comprehensive view on the plant viruses, their importance, and distribution in Iraq. Collectively, there are 43 different viruses reported countrywide. Most studies have been published in local journals, which are published in Arabic. The data presented in this article were gleaned from literatures publicly available from local and international publications as well as conferences and official reports. We are here abstracting the information about virus diseases in Iraq for the first time in order to present it internationally rather than locally.
