According to the morphological and molecular data detailed in this investigation, the isolates were identified as C. geniculata (Hosokawa et al., 2003). Furthermore, the pathogenicity of B. striata leaves was evaluated by coating both leaf surfaces with a conidial suspension (106 conidia per milliliter), in both intact and wounded areas. At 26 degrees Celsius in a greenhouse exposed to natural sunlight and covered with plastic bags for humidity control, five inoculated leaves and three non-inoculated leaves (negative control treated with sterile distilled water) were maintained for 72 hours. Seven days after the incident, the wounds developed small, circular spots. Two weeks subsequent to inoculation, the symptomatic leaves exhibited patterns mirroring the initial disease manifestation, in contrast to the robust health of the control foliage. No infection was evident in the inoculated, undamaged leaves. Employing Koch's postulates, C. geniculata was successfully re-isolated from all five inoculated leaves. To the best of our knowledge, prior instances of C. geniculata infection within the B. striata species have not been recorded.

The plant Antirrhinum majus L., appreciated for its medicinal and ornamental attributes, is commonly grown throughout China. In October 2022, A. majus plants were observed stunted in growth with yellowish leaves and containing a large number of galls on roots in a field in Nanning, Guangxi, China (N2247'2335, E10823'426). Ten randomly collected samples were obtained from the rhizosphere soil and the roots of A. majus. Fresh soil was filtered through a Baermann funnel, isolating second-stage juveniles (J2), and yielding an average of 36.29 juveniles per 500 cubic centimeters. Gall roots, subjected to microscopic dissection, produced 2+042 males per collected sample. The species Meloidogyne enterolobii was identified through morphological analysis, including the examination of the female perineal pattern, and by conducting DNA-based studies. The morphometric analyses of female perineal structures revealed patterns consistent with the initial description of M. enterolobii Yang and Eisenback (1983) from the Enterolobium contortisilquum (Vell.) plant. Yang and Eisenback (1983) investigated Morong, a place located within China. Ten male specimens were measured for body length (range 14213-19243 m, average 16007 5532 m), body diameter (range 378-454 m, average 413 080 m), stylt length (range 191-222 m, average 205 040 m), spicule length (range 282-320 m, average 300 047 m), and DGO (range 38-52 m, average 45 03 m). J2 (n=20) measurements included body length (4032-4933 meters, average 4419.542 meters), body diameter (144-87 meters, average 166.030 meters), parameter a (219-312 meters, average 268.054 meters), c (64-108 meters, average 87.027 meters), stylet length (112-143 meters, average 126.017 meters), DGO (29-48 meters, average 38.010 meters), tail length (423-631 meters, average 516.127 meters), and hyaline tail terminus length (102-131 meters, average 117.015 meters). M. enterolobii's original description (Yang and Eisenback, 1983) exhibits comparable morphological characteristics. A. majus 'Taxiti' plants, grown from seeds directly sown in a 105-cm-diameter pot filled with 600ml of a sterilized peat moss/sand (11:1 v/v) soil medium, underwent pathogenicity tests within the glasshouse environment. Fifteen plants were inoculated with 500 J2 nematodes per pot, collected from the original field, a week after initial planting, while five additional plants remained uninoculated as a control group. Symptoms, matching those seen in the field, appeared in the above-ground parts of all the inoculated plants after 45 days had passed. Control plant samples showed no symptoms whatsoever. Applying the Belair and Benoit (1996) method, the RF value of the inoculated plants was determined 60 days after inoculation, with an average result of 1465. Analysis of J2 samples in this experiment included sequencing of the 28S rRNA-D2/D3, ITS, and COII -16SrRNA 3 region, ultimately confirming their identity as M. enterolobii. Polymerase chain reaction primers D2A/D3B (De Ley et al., 1999), F194/5368r (Ferris et al., 1993), and C2F3/1108 (Powers and Harris, 1993) were used to confirm species identification. Sequences possessing GenBank accession numbers OP897743 (COII), OP876758 (rRNA), and OP876759 (ITS) were found to have a 100% match with other M. enterolobii populations in China, corresponding to the sequences with numbers MN269947, MN648519, and MT406251. Highly pathogenic, M. enterolobii has been observed in vegetables, ornamental plants, guava (Psidium guajava L.), and weeds across China, Africa, and the Americas, as detailed in the literature (Brito et al., 2004; Xu et al., 2004; Yang and Eisenback, 1983). Lu et al. (2019) observed an infection of the medicinal plant, Gardenia jasminoides J. Ellis, by M. enterolobii within China's botanical landscape. The ability of this organism to thrive on crop varieties that are resistant to root-knot nematodes in tobacco (Nicotiana tabacum L.), tomato (Solanum lycopersicum L.), soybean (Glycine max (L.) Merr.), potato (Solanum tuberosum L.), cowpea (Vigna unguiculata (L.) Walp.), sweetpotato (Ipomoea batatas (L.) Lam.), and cotton (Gossypium hirsutum L.) warrants concern. Hence, this species was subsequently included on the EPPO's A2 Alert List, beginning in 2010. M. enterolobii has been found to naturally infect the medicinal and ornamental herb A. majus in Guangxi, China, marking the first such report.

Puding County, located within Guizhou Province of China, holds the most significant position in the cultivation and production of Allium tuberosum. In Puding County, situated at 26.31°N, 105.64°E, white leaf spots were seen on the Allium tuberosum plant in 2019. Initial occurrences of white spots, varying in shape from elliptical to irregular, were first noted on the leaf apices. Disease progression resulted in spots progressively uniting, forming necrotic areas with a yellow rim, leading to the death of leaf tissue; sometimes, gray mold was present on the dead foliage. Assessments indicated that the percentage of diseased leaves spanned from 27% to 48%. To pinpoint the causative agent, 150 leaf tissue samples (5 mm x 5 mm) were harvested from disease-free connecting points of 50 affected leaves. After 30 seconds of 75% ethanol disinfection, leaf tissues were treated with 0.5% sodium hypochlorite for 5 minutes, then thoroughly rinsed with sterile water three times before being transferred to potato dextrose agar (PDA) plates, which were incubated in the dark at 25 degrees Celsius. continuing medical education Multiple cycles of the final step were undertaken to procure the purified fungal specimen. The grayish-green colonies were characterized by white, round margins. Conidiophores, ranging from 27-45 µm in length and 27-81 µm in width, displayed a brown coloration and were either straight, flexuous, or branched with visible septa. Brown conidia, measuring 8-34 m by 5-16 m, were characterized by the presence of 0-5 transverse septa and 0-4 longitudinal septa. Amplification and sequencing steps were undertaken for the 18S nuclear ribosomal DNA (nrDNA; SSU), 28S nrDNA (LSU), RNA polymerase II second largest subunit (RPB2), internal transcribed spacer (ITS), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and translation elongation factor 1-alpha (TEF-) (Woudenberg et al. 2013) elements. GenBank's repository now includes the sequences ITS OP703616, LSU OP860684, SSU OP860685, GAPDH OP902372, RPB2 OP902373, and TEF1- OP902374. A BLAST comparison established 100% sequence identity between the strain's ITS, LSU, GAPDH, RPB2, SSU, and TEF1- genes and those of Alternaria alternata (ITS LC4405811, LSU KX6097811, GAPDH MT1092951, RPB2 MK6059001, SSU ON0556991 and TEF1- OM2200811), with 689/731, 916/938, 579/600, 946/985, 1093/1134, and 240/240 base pair matches, respectively. 1000 bootstrapping replicates, using the maximum parsimony method within PAUP4, were implemented to construct a phylogenetic tree for each dataset. Through a combination of morphological characteristics and phylogenetic analysis, FJ-1 was classified as Alternaria alternata, corroborating the findings of Simmons (2007) and Woudenberg et al. (2015). Preserved in the Agricultural Culture Collection of China, the strain's preservation number is ACC39969. Healthy Allium tuberosum leaves, bearing wounds, were inoculated with Alternaria alternata conidia (10⁶ conidia/mL) and 4 mm round plugs of mycelium to determine its disease-causing potential.
