Bacterial leaf streak caused by Xanthomonas translucens pv. undulosa (Xtu) is an important disease of wheat (Triticum aestivum) and barley (Hordeum vulgare) worldwide. Transcription activator-like effectors (TALEs) play determinative roles in many the plant diseases different species pathovars Xanthomonas, but their role these has not been characterized. ICMP11055 a highly virulent Xtu strain from Iran. The aim this study was to better understand genetic diversity assess TALEs bacterial...
Chestnut-leaved oak ( Quercus castaneifolia ) and oriental beech Fagus orientalis are among the major tree species in Hyrcanian forests. Brenneria goodwinii was identified as causal agent of necrotic lesions stem bleeding on affected trees different countries. Oak with symptoms were observed a few forest sites northern Iran. The objectives present study to identify characterize agents bark canker develop primer set for specific detection, using polymerase chain reaction (PCR), strains. A...
Abstract Persian walnut ( Juglans regia ) has a considerable economic importance worldwide. However, the vigor and vitality of trees were heavily affected by bark canker during last few years. Irregular longitudinal cankers in outer bark, stem tissue necrosis, bleeding with black-colored exudates observed Kermanshah, Hamedan, Markazi, Alborz, Isfahan, Qom, Semnan, Razavi Khorasan provinces western, central eastern Iran 2018 2019. A total 150 symptomatic samples collected from order to...
The bulb onion (Allium cepa) is second only to tomatoes in value of vegetable crops cultivated worldwide. Water-soaked lesions, bleaching and blight on leaves slippery skin, sour soft rot near the neck centre bulbs were observed surveys fields, storage as well fruit markets northwestern provinces Iran 2020. Thirty-four samples collected from fields East Azerbaijan, West Azerbaijan Zanjan central Bonab city. Fifty bacterial strains isolated symptomatic samples. Pathogenicity was confirmed by...
Abstract Lawson cypress ( Chamaecyparis lawsoniana ), an important landscape tree, is widely planted in gardens and parks throughout Iran. Crown gall disease on trees was observed Sari Juybar Counties, Mazandaran province, northern Iran, 2017. Isolation from galls potato dextrose agar (PDA) containing CaCO 3 yielded bacterial colonies, the predominant types of which were purified selected for characterization. The isolates Gram‐negative, oxidase positive, able to grow 2% NaCl produced...
An outbreak of a new emerging disease on walnut (Juglans regia) has been reported in northwestern Iran (West Azerbaijan, East Azerbaijan and Zanjan provinces) the summer 2018. Vertical oozing cankers were observed trunks main branches diseased trees especially lower part trunk, several cases near crown. Principal symptoms stem bleeding with dark exudates (brown to black resembling bitumen) necrosis inner bark (Fig. 1). Isolation bacterial strains from infected tissues was performed nutrient...
Abstract Hyrcanian forests comprise a long strip along the southern coast of Caspian Sea in northern Iran. Oriental beech ( Fagus orientalis ) is one most valuable forest tree species forests. Bark necrosis and bleeding spots oriental were observed Savadkuh Mazandaran province during summer 2021. Ten samples collected from symptomatic trees. The bark canker symptoms included stem tissue necrosis, dark brown to black on trunk, with exudates lesions inner bark. Twenty‐six strains culturable...
ABSTRACT Date palm ( Phoenix dactylifera ) considered a main income and food source for local individuals in producing countries. However, offshoot decline bud rot disease was observed some groves Khuzestan province as major date producer Iran. Thirty‐five samples with were collected from diseased of six cities during 2019–2021. Yellowing outer leaves, black, brown or reddish spots on petioles at the early stage, which gradually continues to rot. Seventy‐nine isolated symptomatic among 38...
ABSTRACT Leaf spot and soft rot of ornamental plants were observed in the Alborz Markazi provinces during summer autumn 2022. Eighteen samples collected from symptomatic Karaj Arak cities. Necrotic leaf spots surrounded by a broad yellow halo affected pothos ( Epipremnum aureum ) compact dragon Dracaena compacta plants. On severely affected, leaves with margin observed. Soft symptoms which turned dark brown areas on diseased jade Crassula ovata ). The colonies bacterial strains...
Agaricus bisporus is globally a most extensively consumed species of edible mushrooms. Ethylene secreted by A. mycelium suppress the initiation fructification. 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase-producing bacteria decrease content ethylene cleaving ACC produced hyphae to α-ketobutyrate and ammonia. This study evaluated effect various salts on population Bacillus velezensis UTB96 with deaminase activity button mushroom. The results indicated that CaCl2, MnSO4 MgSO4...
Date palm (Phoenix dactylifera) is an important fruit crop in Southwest Asia and North Africa. Khuzestan a major province for date production Iran. However, offshoot decline bud rot disease were observed groves this during 2019–2021. Five diseased samples collected from Abadan, Ahvaz Karun western Iran September November 2019. Pale green yellow leaves young offshoots affected by the disease. The dried over time base of was soft dark brown which led to wilting (Fig. 1). Tissues margins...
