Fig. 1 (Colour online) Symptoms and morphological characteristics of the leaf spot disease of pineapple (Ananas comosus) caused by Curvularia clavata. a, Typical symptoms on naturally infected leaves, spotting and blight. b, Purified colony of Curvularia clavata isolate grown on potato dextrose agar at 28°C with a 12-h photoperiod for 7 days. c, Microscope views of spore morphology showing conidia (scale bar 20 μm). d, Detached pineapple leaves exhibiting necrotic spots and blight 7 days after inoculation with Curvularia clavata isolate BL7.
Fig. 2 Phylogenetic tree constructed by the neighbour-joining method comparing the GPD sequences of representative isolates BL3 and BL7 with sequences of related species. GenBank accessions are shown next to each isolate. Numbers on branches are the frequency with which a cluster appears in a bootstrap test of 1000 runs.
