Abstract

Fungal isolates from chilli ( Capsicum spp.) fruits in Thailand that showed typical anthracnose symptoms were identified as Colletotrichum acutatum , C . capsici and C . gloeosporioides . Phylogenetic analyses from DNA sequence data of ITS rDNA and β‐tubulin ( tub 2) gene regions revealed three major clusters representing these three species. Among the morphological characters examined, colony growth rate and conidium shape in culture were directly correlated with the phylogenetic groupings. Comparison with isolates of C . gloeosporioides from mango and C . acutatum from strawberry showed that host was not important for phylogenetic grouping. Pathogenicity tests validated that all three species isolated from chilli were causal agents for chilli anthracnose when inoculated onto fruits of the susceptible Thai elite cultivar Capsicum annuum cv. Bangchang. Cross‐infection potential was shown by C . acutatum isolates originating from strawberry, which produced anthracnose on Bangchang. Interestingly, only C . acutatum isolates from chilli were able to infect and produce anthracnose on PBC 932, a resistant genotype of Capsicum chinense . This result has important implications for Thai chilli breeding programmes in which PBC 932 is being hybridized with Bangchang to incorporate anthracnose resistance into chilli cultivars.

  • Yoon et al. (2004) and Than et al. (2008) found that 'PBC 932' was highly susceptible to C. acutatum isolates.

    “However, Yoon et al.(2004) and Than et al.(2008) found that the 'PBC 932' was highly susceptible to C. acutatum isolates.”

    The Pathogenicity section (p. 7) gives PBC 932 a score of 7, ‘very susceptible,’ when fruits were wounded and inoculated with C. acutatum isolates from chilli. The claim omits those conditions: C. acutatum isolates from strawberry caused no symptoms, and no isolates caused anthracnose symptoms without wounding. (LLM, conf=0.90)

  • Anthracnose of chilli is caused by more than one Colletotrichum species, including C. acutatum, C. capsici, C. gloeosporioides, and C. coccodes.

    “Anthracnose of chilli has been shown to be caused by more than one Colletotrichum species including C. acutatum (Simmonds), C. capsici (Syd.)Butler and Bisby, C. gloeosporioides (Penz.)Penz.and Sacc., and C. coccodes (Wallr.)S. Hughes (Simmonds, 1965;Johnston and Jones, 1997;Kim et al., 1999;Nirenberg et al., 2002;Voorrips et al., 2004;Sharma et al., 2005;Pakdeevaraporn et al., 2005;Than et al., 2”

  • Several studies have screened C. acutatum against chilli genotypes and found that Capsicum baccatum genotype 'PBC 80' is a genetic resource pool for resistance to anthracnose.

    “Several studies (AVRDC, 1999;Yoon et al., 2004) have screened C. acutatum, which is the very virulent species (Than et al., 2008), against chilli genotypes and found that Capsicum baccatum genotype 'PBC 80' is a genetic resource pool for resistance to anthracnose.”

  • Than et al. (2008) differentiated isolates of chilli anthracnose from Thailand into three species: C. acutatum, C. capsici and C. gloeosporioides, based on morphological characterization, sequencing based on rDNA-ITS region and partial beta tubulin gene and pathogenicity testing.

  • DNA sequence analyses have been used to characterize and analyze the taxonomic complexity of Colletotrichum to overcome the inadequacies of traditional morphology based identification schemes.

    “To overcome the inadequacies of traditional morphology based identification schemes, DNA sequence analyses have been used to characterize and analyze the taxonomic complexity of Colletotrichum (Sreenivasaprasad et al., 1996;Moriwaki et al., 2002;Du et al., 2005;Photita et al., 2005;Than et al., 2008).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
