Ciri dan struktur

Hemileia vastatrix is a multicellular basidiomycete fungus of the order Pucciniales (previously also known as Uredinales) that causes coffee leaf rust (CLR), a disease affecting the coffee plant. Coffee serves as the obligate host of coffee rust, that is, the rust must have access to and come into physical contact with coffee (Coffea sp.) in order to survive. CLR is one of the most economically important diseases of coffee, worldwide. Previous epidemics have destroyed coffee production of entire countries. In more recent history, an epidemic in Central America in 2012 reduced the region's coffee output by 16%. by covering the leaves with fungus spores and/or causing leaves to drop from the plant. The reduction in photosynthetic ability (plant's metabolism) results in a reduction in quantity and quality of flower and fruit production, which ultimately reduces the beverage quality. The mycelium with uredinia looks yellow-orange and powdery, and appears on the underside of leaves as points ~0.1 mm in diameter. Young lesions appear as chlorotic or pale yellow spots some millimetres in diameter, the older being a few centimetres in diameter. Hyphae are club-shaped with tips bearing numerous pedicels on which clusters of urediniospores are produced. Telia are pale yellowish teliospores often produced in uredinia; teliospores more or less spherical to limoniform, 26–40 × 20–30 μm in diameter, wall hyaline to yellowish, smooth, 1 μm thick, thicker at the apex, pedicel hyaline. Urediniospores are more or less reniform, 26–40 × 18-28 μm, with hyaline to pale yellowish wall, 1–2 μm thick, strongly warted on the convex side, smooth on the straight or concave side, warts frequently longer (3–7 μm) on spore edges.

Habitat dan peran ekologis

Hemileia vastatrix is an obligate parasite rust fungus that invades and lives on the plants of genus Coffea. In laboratory studies, Hemileia vastatrix has also been observed to be capable of invading Arabidopsis thaliana, but never develops the haustoria structure that is a key part of its parasitism of its known host plants in the wild. The rust needs suitable temperatures to develop (between 16 °C and 28 °C). High altitude plantations are generally colder, so inoculum will not develop as easily as in plantations located in warmer regions. The presence of free water is required for infection to be completed. Loss of moisture after germination starts inhibits the whole infection process. Sporulation is most influenced by temperature, humidity, and host resistance. The colonization process is not dependent on leaf wetness but is influenced greatly by temperature and by plant resistance. The main effect of temperature is to determine the length of time for the colonization process (incubation period). Hemileia vastatrix has two fungal parasites, Verticillium haemiliae and Verticillium psalliotae. The fungus is of East African origin, but is currently endemic to all producing regions.
