Spore germination and non-germination were determined using a 40x magnification light microscope following 72 hours of incubation at 26.2 degrees Celsius in a humid chamber, assessing viability. Spore viability was maintained over the duration of the experiment across all the tested carrier types, demonstrating a 26% overall rate of survival. A statistically significant difference in spore preservation was seen (p < 0.005) between these diverse carrier materials. Maximum spore viability occurred at days 7 and 15 post-inoculation, with cloth and plastic carriers posing a considerable risk for fungal transportation. Mathematical models of spore viability's change over time were tailored to the experimental data using the Bayesian information criterion. The investigation's findings supported the fermentation process's contribution to suppressing M. roreri growth and the potential of carrier materials in facilitating fungal propagation.
Italian agriculture features a significant presence of cultivated strawberry plants (Fragaria ananassa Duch.). Mild symptoms of an unknown leaf spot disease, affecting 5% to 10% of June-bearing strawberries (cultivar), began to surface during the months of May and June 2022. July 2021 marked the transplanting of Elodi plants to a commercial agricultural operation situated in the province of Cuneo, within northern Italy. From September to November 2022, the symptoms were evident in 10-15% of the plants that were moved in July 2022. click here A 600 square meter swathe of the field bore the brunt of the disease, impacting both recently emerged and older leaves. The plants received fungicide treatments, comprising sulphur and Tiovit Jet, along with penconazole and Topas 10 EC, in accordance with the integrated pest management strategy throughout their growing period. Disease symptoms included purplish to brown necrotic leaf spots, 1-3 mm in diameter, and the presence of chlorotic leaf margins. Small to large, elongated or necrotic black lesions on the petioles were occasionally observed, which caused the leaves to die. After approximately four months, perithecia were observed within the plant material, with measured dimensions fluctuating from 144 to 239 meters and 200 to 291 meters, using a total of 10 specimens for analysis. Leaves and petioles, affected by disease, from roughly ten plants, were subjected to surface disinfection in a 1% sodium hypochlorite solution for one minute, then rinsed with sterile water, and ultimately cultured on potato dextrose agar supplemented with 25 milligrams of streptomycin sulfate per liter. The white, cottony colonies of a fungus were repeatedly isolated and cultured in pure form on PDA. From 21-day-old colonies cultured in PDA at 22°C with a 12-hour photoperiod, the dimensions of biguttulate conidia with rounded ends were measured. Fifty conidia (n=50) demonstrated a range from 43 to 80 micrometers and 12 to 29 micrometers, with an average size of 61.23 micrometers. Through an analysis of the colony and conidia morphology, the isolate was identified as belonging to the Gnomoniopsis genus. The conclusions reached by Walker et al. (2010) are that. The E.Z.N.A. Fungal DNA Mini Kit (Omega Bio-Tek, Darmstadt, Germany) was utilized to extract fungal DNA from a pure culture of the representative fungal isolate FR2-22. Using the ITS1/ITS4 primers for the internal transcribed spacer (ITS) region and the EF-728F/EF2 primers for the partial translation elongation factor 1- (TEF) gene, amplification and sequencing were performed to determine the identification (Udayanga et al., 2021). At the BMR Genomics Centre in Padova, Italy, the purified PCR products were sequenced, producing 551bp (ITS) and 652bp (TEF) sequences, subsequently lodged in GenBank (Accession nos.). The identifiers OQ179950 and OQ190173 are presented, in that order. The BLASTn search of both sequences revealed 100% sequence identity to the ITS and TEF loci of Gnomoniopsis fructicola isolates VPRI 15547 and CBS 27551, as found in the GenBank database with their respective accession numbers. Concerning MT378345 and MT383092. In two separate greenhouse compartments, the pathogenicity of the FR2-22 isolate was investigated using biological tests. Each compartment contained three replicates, each consisting of a single plant in a pot, and was maintained at a temperature of 20-24 degrees Celsius and a humidity level of 80-90 percent. The forty-day-old strawberry plants (cv. ) display a healthy leaf structure. The FR2-22 isolate, grown on PDA at 25°C for 20 days, yielded conidia that were sprayed onto Elodi at a concentration of 1-5 x 10^6 per milliliter. The control (water-sprayed plants) continued to experience the identical environmental conditions. Small leaf spots, mimicking previous farm symptoms, appeared 15 days after inoculation. Hepatozoon spp Moreover, a significant portion of the leaves, ranging from 30% to 40%, exhibited symptoms analogous to those seen in the field after a period of 25 to 40 days, whereas the control group maintained its healthy state. The affected leaves and petioles yielded the same fungal isolate, which was re-isolated repeatedly and identified via TEF sequencing. The taxonomic naming of Gnomoniopsis fragariae is now standardized. Fragaria ananassa plants in Australia and the USA have shown a prior instance of the disease nov., the newly named form of Gnomoniopsis fructicola (Udayanga et al., 2021), according to Farr and Rossman (2023). As far as we are aware, this is the first recorded instance of G. fragariae's presence affecting strawberries cultivated in Italy. Future Italian strawberry harvests may suffer due to the disease caused by this pathogen. For the prevention of disease epidemics, nurseries require the use of healthy propagation material and the implementation of strict disease management techniques.
Grapevine (Vitis labrusca L.), belonging to the Vitaceae family and originating in North America, is cultivated as a table grape. A survey for grapevine diseases in Chikkaballapur's Nandi village (13°22′59.7″N 77°42′33.4″E), Karnataka, India, in May 2022, revealed an abundance of yellow rust pustules on the lower leaf surfaces of 'Bangalore Bule' grapevines. At the point of the crop's maturity, the assessment of rust disease severity followed the guidelines of Angelotti et al. (2008), reaching a maximum level of 10%. Small, raised yellow pustules, appearing in abundance on the abaxial surface, mirrored the chlorotic spots characteristically found on the adaxial surface. Extensive spotting across the leaf, accompanied by leaf drop, characterizes severe conditions. Similar disease symptoms were consistently reported in the works of Ono (2000), Weinert et al. (2003), and Primiano et al. (2017). In a glasshouse set at 25 degrees Celsius, a pathogenicity test was executed on 'Bangalore Bule' grapevine cuttings. From diseased leaves, urediniospores were collected with a brush. A 3104 ml-1 suspension in distilled water served as the inoculum for the abaxial leaf surface. The control plants were treated with a spray of distilled water. The pathogen was confirmed in the leaves after 15 to 17 days, evidenced by the presence of symptoms, alongside microscopic examination confirming the urediniospores. Obovoid to obovoid-ellipsoid, sessile urediniospores, possessing short pedicels, were uniformly echinulate, exhibiting dimensions in the range of 4298-3254 x 3137-2515 m. On the alternate host, Meliosma simplicifolia, the specific stage of the Phakopsora fungus has been observed, according to Hosagoudar (1988). Molecular detection of Phakopsora, as facilitated by the internal transcribed spacer (ITS) region (Rush et al., 2019), was validated through scrutiny of varying ITS segments, namely ITS1, the 58S rRNA gene, and ITS2. Following the manufacturer's protocol, the Macherey-Nagel kit (Düren, Germany) was used to extract total DNA from the urediniospore mass. A Qubit 30 fluorometer (Invitrogen) was employed to ascertain the amount of isolated DNA before subjecting it to polymerase chain reaction (PCR) amplification in the Eppendorf-vapo.protect thermocycler. To target the ITS1, 58S rRNA, and ITS2 regions, ITS1 and ITS4 primers (IDT, Singapore) were utilized, yielding an amplicon of roughly 700 base pairs. Purification of the amplicon was conducted using the Macherey-Nagel Nucleospin gel and PCR clean-up kit (Duren, Germany), adhering to the manufacturer's protocol. The purified amplicon was then sequenced using Sanger's dideoxy chain-termination method, utilizing ABI 3730 (48 capillaries) electrophoresis. The sequence's editing was performed using BioEdit (https//bioedit.software.informer.com/72/). The MUSCLE alignment was used to create the phylogenetic tree in MEGA 11, with the phylogenetic relationships based on the neighbor-joining method, upholding the maximum likelihood principle detailed in the work of Kumar et al. (2018). NCBI's repository now contains the sequence data, accession number OP221661. A GenBank search, using the BLAST algorithm and the Nandi-KA isolate's sequence, uncovered a 97.91% homology with a Phakopsora sp. sequence. The accession number KC8155481 is associated with a 9687% prevalence of Phakopsora euvitis, specifically accession number AB3547901. Analysis of disease manifestations, fungal structure, pathogenicity testing, and ITS sequence data confirmed the fungus as *Phakopsora euvitis*, the grapevine leaf rust pathogen. Similar disease symptoms in Indian grapevines, aligning with the EPPO 2016 report, did not allow for pathogen confirmation. Spine biomechanics Our research indicates that this is the first documented case of Phakopsora euvitis triggering leaf rust disease in grapevines (V. Indian agricultural practices include the cultivation of labrusca grapes.
