Passion fruit (Passiflora edulis Sims.) is popular for its rich taste and nutritional value. The planting area of passion fruit in Guangxi has reached 24,300 ha, with an annual output of 380,000 t (Qian 2023). In March 2023, leave spots on more than half of the plants (cv. Qinmi "NO.9"). Moreover, the incidence of disease on the leaves was approximately 20% in Shabu Town, Qinnan District, Qinzhou City, Guangxi, China (N20˚54'-22˚41', E107˚27'-109˚56'). Leaf diseases were orbicular or irregular in shape, white, whitish-grey, yellowish, or gray in color. When leaves were severely affected, larger blotches were formed with yellow halos. For pathogen isolation, three diseased leaf samples were collected from three gardens, respectively, and 5×5 mm tissues were cut from infected margins, surface-disinfected in 75% ethanol for 15 s, followed by 2% sodium hypochlorite for 1 min, rinsed three times with sterile water, and incubated on PDA at 25°C under 12/12 h light/darkness. After 5 days, ninety cultures were isolated, sixty isolates with similar morphology were retained, and three representative isolates BY-1, BY-2, and BY-4 were randomly selected for further study. On PDA, colonies of the three isolates displayed white or grayish-white. Conidia were single-celled, hyaline, and cylindrical, measuring 17.3±1.5 × 6.3±0.7 μm, 17.8±1.7 × 6.0±0.6 μm, and 16.3±1.4 × 6.4±0.6 μm (n=90) for BY-1, BY-2, and BY-4, respectively. Appressoria were single, brown or black, and irregular in shape, measuring 10.2±1.1×6.5±0.5 μm, 10.5±1.3×7.3±0.6, and 10.9±0.8×7.0±0.8 (n=90) for BY-1, BY-2, and BY-4, respectively. These morphological characteristics were similar to Colletotrichum spp. as previously described (Damm et al. 2019). The isolates were further identified by sequencing the internal transcribed spacer (ITS-ITS1/ITS4), glyceraldehyde-3-phosphate dehydrogenase (GAPDH-GDF/GDR), actin (ACT-512F/783R), partial sequences of the chitin synthase 1 (CHS-1-79F/354R), and beta-tubulin 2 (TUB2-T1/Bt2b) (Zhang et al. 2023). All sequences were deposited in GenBank (ITS: OR741759 to OR741761, GAPDH: OR767654 to OR767656, ACT: OR767657 to OR767659, CHS-1: OR767660 to OR767662, TUB2: OR767651 to OR767653). A phylogenetic tree was built with RAxML version 8.2.10 based on concatenated sequences of ITS-GAPDH-ACT-CHS-1-TUB2. The results revealed that the three isolates clustered with C. plurivorum. To confirm the pathogenicity of the three isolates, attached leaves of healthy 5-month-old passion fruit plants were injured in the middle region with sterile toothpicks and inoculated with 20 μL of spore suspension (106 conidia/mL), and the noninoculated control received 0.05% Tween-20 (6 leaves/plant, 3 plants/treatment). The inoculated plants were kept in a greenhouse at 25°C and covered with plastic bags to maintain high humidity. After 9 days, all inoculated leaves were symptomatic, whereas no symptoms were observed in the control. C. plurivorum was reisolated from infected leaves, confirming Koch's postulates. C. plurivorum has been reported to infect Abelmoschus esculentus (Batista et al. 2020) and Carya illinoinensis in China (Zhang et al. 2023). However, this is the first report of anthracnose caused by C. plurivorum on passion fruit in China. The results can provide a robust basis for scientific prevention and control of anthracnose.
