“…Although C. boninense was earlier reported to be associated with tomato anthracnose in Pahang, Malaysia [ 26 ], this study is the first report of tomato anthracnose caused by C. truncatum in Malaysia. Other reports of tomato anthracnose caused by C. truncatum have been published in China [ 27 ], India [ 28 ] and Trinidad [ 29 ].…”

Tomato (Solanum lycopersicum L.) is a popular nutritious vegetable crop grown in Malaysia and other parts of the world. However, fungal diseases such as anthracnose pose significant threats to tomato production by reducing the fruit quality and food value of tomato, resulting in lower market prices of the crop globally. In the present study, the etiology of tomato anthracnose was investigated in commercial tomato farms in Sabah, Malaysia. A total of 22 fungal isolates were obtained from anthracnosed tomato fruits and identified as Colletotrichum species, using morphological characteristics. The phylogenetic relationships of multiple gene sequence alignments such as internal transcribed spacer (ITS), β-tubulin (tub2), glyceraldehyde 3-phosphate dehydrogenase (gapdh), actin (act), and calmodulin (cal), were adopted to accurately identify the Colletotrichum species as C. truncatum. The results of pathogenicity tests revealed that all C. truncatum isolates caused anthracnose disease symptoms on inoculated tomato fruits. To our knowledge, the present study is the first report of tomato anthracnose caused by C. truncatum in Malaysia. The findings of this study will be helpful in disease monitoring, and the development of strategies for effective control of anthracnose on tomato fruits.

“…It is one of the important seed-borne diseases of soybean and chili pepper (Begum et al, 2007;Naveen et al, 2021). In recent years, it has been reported that it is also pathogenic on tomatoes (Diao et al, 2014;Saini et al, 2017;Villafana et al, 2018;Almaraz Sánchez et al, 2019). It also causes necrotic spots on the leaves (He et al, 2016) although it causes more fruit infections.…”

Anthracnose caused by Colletotrichum truncatum (Schwein.) Andrus and W.D. Moore, is an economically important disease of most tropical crops. In recent years, it has been reported that it is also pathogenic on tomatoes. In this study, the infected fruits were obtained from Antalya province in 2019. Isolates were purified by taking single spore. Conidia were measured as 22.5-32.5 × 3.75 µm. DNA isolation was carried out using the CTAB method. After the PCR amplification, the PCR product was run on agarose gel, visualized with a UV transilluminator, and sequenced. Phylogenetic analysis was conducted in MEGA 7. Based on morphological and phylogenetic analysis, the CT isolate was identified as C. truncatum. Pathogenicity tests were carried out using tomato leaves and cherry tomatoes. The inoculated leaves and tomatoes were incubated on a moist filter paper in climate chambers under 27 °C temperature and 12:12 h light-dark conditions. Acervuli were observed on infected tissues on the 7 th day of inoculation. Haplotype, the number of haplotypes, and nucleotide diversity were analyzed by DnaSP 6.0 software. 8 haplotypes were determined according to the ITS sequence of 46 C. truncatum isolates from different countries. The median-joining network analysis of haplotypes was drawn using the NETWORK 10 program. It was determined that the CT isolate reported with this study from Turkey and the other reference isolates reported on tomatoes were in the H1 which is the most common haplotype.
