Diaporthe subclavata

Ciri dan struktur

Asexual morph: Conidiomata pycnidial, multi-pycnidia grouped together, globose, black, erumpent, coated with white hyphae, creamy to yellowish conidial droplets exuded from central ostioles. Conidiophores hyaline, densely aggregated, cylindrical, straight to sinuous, tapering towards the apex, 13.5–23.0 × 2.0–3.0 μm. Alpha conidiogenous cells 7.0–10 × 1.8–2.5 μm, cylindrical, terminal, slightly curved. Beta conidiogenous cells 10.5–13.5 × 0.9–1.5 μm, cylindrical, hyaline, tapering towards the apex. Alpha conidia, hyaline, smooth, aseptate, ellipsoidal, multi-guttulate, apex subobtuse, base subtruncate, 4.7–5.8 × 2.4–2.9 µm (mean = 5.3 × 2.6 μm, n = 20). Beta conidia hyaline, aseptate, filiform, few guttulate, slightly curved, tapering towards the both ends, 25.5–32.0 × 1.0–1.6 µm (mean = 27.5 × 1.3 μm, n = 20). Gamma conidia and sexual morph not observed. Pure culture was isolated by subbing hyphal tips growing from surface sterilized diseased material. Colonies on PDA cover the Petri dish diameter after incubation for 15 days in dark conditions at 25 °C. Aerial mycelium white, cottony, feathery, with concentric zonation, white on surface side, pale brown to black on reverse side.

Habitat dan peran ekologis

Pure culture was isolated by subbing hyphal tips growing from surface sterilized diseased material. Colonies on PDA cover the Petri dish diameter after incubation for 15 days in dark conditions at 25 °C. Aerial mycelium white, cottony, feathery, with concentric zonation, white on surface side, pale brown to black on reverse side. Diaporthe subclavata was originally described from the leaf with citrus scab of Citrus unshiu in Fujian Province, China (Huang et al. 2015). In the present study, isolated strain SAUCC194.66 from symptomatic leaves of Pometia pinnata was congruent with D. subclavata based on morphology and DNA sequences data (Fig. 1). We therefore present a description and illustration of D. subclavata as a known species for this clade, found on new host.
