The isolates, as detailed in this study through their morphological and molecular characteristics, were confirmed to be C. geniculata, as reported by 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. Five inoculated leaves and three non-inoculated leaves (acting as a negative control, treated with sterile distilled water) were held within a greenhouse environment at 26 degrees Celsius, exposed to natural sunlight, and enclosed with plastic bags for 72 hours to preserve humidity. On the seventh day, small, round spots emerged from the healing wounds. After a fortnight, the inoculated plants displayed disease symptoms analogous to the original sample, while the control plants maintained their pristine health. Inoculated leaves, free of wounds, displayed no symptoms of infection. Koch's postulates confirmed the successful re-isolation of C. geniculata from each of the five inoculated leaves. According to our current understanding, there has been no documented case of C. geniculata infection in B. striata previously.

Antirrhinum majus L. is a medicinal and ornamental herb, commonly grown with care in 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). Randomly selected samples from the rhizosphere soil and roots of A. majus amounted to ten. Soil samples were subjected to Baermann funnel filtration to isolate second-stage juveniles (J2), resulting in a mean of 36.29 juveniles per 500 cm3. Employing a microscope, a dissection of the gall roots recovered 2+042 male specimens per sample. Analysis of DNA and the unique morphological characteristics, including the female perineal pattern, established the species as Meloidogyne enterolobii. 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's 1983 work includes analysis of Morong, a location situated within China. In a sample of 10 male specimens, measurements included body length (14213-19243 m, mean 16007 5532 m), body diameter (378-454 m, mean 413 080 m), stylt length (191-222 m, mean 205 040 m), spicules length (282-320 m, mean 300 047 m), and DGO (38-52 m, mean 45 03 m). J2 measurements (n=20) included body length (4032-4933 m, average 4419.542 m); body diameter (144-87 m, average 166.030 m); parameter a (219-312 m, average 268.054 m); parameter c (64-108 m, average 87.027 m); stylet length (112-143 m, average 126.017 m); DGO (29-48 m, average 38.010 m); tail length (423-631 m, average 516.127 m); and hyaline tail terminus length (102-131 m, average 117.015 m). Similar morphological characteristics are evident in the 1983 Yang and Eisenback description of M. enterolobii. A 105-cm-diameter pot, filled with 600ml of sterilized peat moss/sand (11:1 v/v) soil, was used to cultivate A. majus 'Taxiti' seedlings from seeds, and pathogenicity tests were subsequently performed on these seedlings in a glasshouse setting. On the seventh day, fifteen plants were inoculated with a 500 J2 nematodes per pot, a sample collected from the original field site, while five plants served as an untreated control. After 45 days, all inoculated plants' above-ground components exhibited symptoms virtually identical to those noted in the field. Control plant samples showed no symptoms whatsoever. The RF values of the inoculated plants, determined 60 days after inoculation using the methodology of Belair and Benoit (1996), averaged 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. Species identification was verified through the application of polymerase chain reaction primers D2A/D3B (De Ley et al., 1999), F194/5368r (Ferris et al., 1993), and C2F3/1108 (Powers and Harris, 1993). The 100% similarity observed between sequences assigned GenBank accession numbers OP897743 (COII), OP876758 (rRNA), and OP876759 (ITS) and those of other M. enterolobii populations from China (MN269947, MN648519, MT406251) highlights their genetic affinity. The highly pathogenic species M. enterolobii has been widely reported across China, Africa, and the Americas to be present in vegetables, ornamental plants, guava (Psidium guajava L.), and weeds (Brito et al., 2004; Xu et al., 2004; Yang and Eisenback, 1983). Gardenia jasminoides J. Ellis, a medicinal plant, suffered an infection from M. enterolobii in China, as documented by Lu et al. (2019). Its observed aptitude for development on crop species possessing resistance genes 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.) presents a notable concern. This resulted in the European and Mediterranean Plant Protection Organization placing this species on their A2 Alert List in the year 2010. The medicinal and ornamental herb A. majus in Guangxi, China, is now reported to have experienced its first natural infection by M. enterolobii. This study received financial support from the National Natural Science Foundation of China (grant 31860492), the Natural Science Foundation of Guangxi (grant 2020GXNSFAA297076), and the Guangxi Academy of Agricultural Sciences Fund, China (grants 2021YT062, 2021JM14, 2021ZX24).

The most important area for growing Allium tuberosum in Guizhou Province, China, is Puding County. Observations of white leaf spots on Allium tuberosum plants in Puding County (26.31°N, 105.64°E) began during the year 2019. Initial occurrences of white spots, varying in shape from elliptical to irregular, were first noted on the leaf apices. As the disease escalated, spots gradually fused together, forming necrotic areas with yellow margins, causing leaf tissue death; gray mold was sometimes observed on the dead leaves. The study projected a diseased leaf rate ranging from 27% to 48%. To isolate the disease-causing agent, 150 leaf sections (5 mm x 5 mm) were collected from the healthy connection points of 50 affected leaves. Leaf tissues were disinfected with 75% ethanol for 30 seconds, then immersed in 0.5% sodium hypochlorite for 5 minutes, rinsed with sterile water thrice and then cultured onto potato dextrose agar (PDA) plates which were maintained in the dark at 25 degrees Celsius. GW4869 inhibitor The purified fungus materialized only after several reiterations of this final stage. Grayish-green colonies were outlined by white, round margins. Brown, straight, flexuous, or branched conidiophores, which possessed septa, displayed dimensions of 27-45 µm in length and 27-81 µm in width. The dimensions of the brown conidia, 8-34 m by 5-16 m, correlated with a variable number of septa, namely 0-5 transverse 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 now contains the following sequences: ITS OP703616, LSU OP860684, SSU OP860685, GAPDH OP902372, RPB2 OP902373, TEF1- OP902374. Analysis using BLAST, revealed that the ITS, LSU, GAPDH, RPB2, SSU, and TEF1- genes of the strain displayed 100% identity to the corresponding genes in Alternaria alternata (ITS LC4405811, LSU KX6097811, GAPDH MT1092951, RPB2 MK6059001, SSU ON0556991, and TEF1- OM2200811) with complete matches of 689/731, 916/938, 579/600, 946/985, 1093/1134, and 240/240 base pairs, respectively. A phylogenetic tree, derived via 1000 bootstrap replicates using the maximum parsimony method in PAUP4, was constructed for each dataset. FJ-1's identification as Alternaria alternata derives from a comparative study of its morphological attributes and phylogenetic relationships, as presented in Simmons (2007) and Woudenberg et al. (2015). The strain, bearing preservation number ACC39969, was kept within the Agricultural Culture Collection of China. Using a conidial suspension (10⁶ conidia/mL) and 4 mm round plugs of Alternaria alternata mycelium, wounded healthy Allium tuberosum leaves were inoculated to determine the pathogenicity of the fungus.
