Puccinia monoica

Ciri dan struktur

Infection of host plants (including Boechera and several other members of the mustard family) occurs via wind-borne basidiospores in late summer. Upon germination of the spores, fungal hyphae penetrate the stem of the mustard plant and siphon off nutrients. However, in order to reproduce sexually, the fungus must facilitate the transfer of spermatia from the spermatogonia on this plant to receptive hyphae borne in the spermatogonia on another infected mustard plant. To accomplish this, the fungus sterilizes the host plant, preventing it from producing true flowers. Instead, it forces the infected plant to grow clusters of leaves into brilliant yellow pseudoflowers bearing the fungal spermatogonia. Insects visiting the pseudoflowers transfer spermatia from one host plant to another, in the same way that pollinators transfer pollen between the true flowers of uninfected plants. Spermatia transferred in this way fuse with receptive spermatogonial hyphae on the recipient plant. The resulting hyphae subsequently form aecia. At this time, the pseudoflowers lose their green colour and stop producing nectar. Spores produced in the aecia, referred to as aeciospores, are responsible for infecting P. monoicas alternate host plant (a grass species of Koeleria, Trisetum, or Stipa). Upon germination hyphae produced by the aeciospores penetrate the grass, leading to the production of uredia. The uredia produce urediniospores capable of infecting more grass plants. Ultimately, telia are produced on the infected grasses. This leads to production of basidia and basidiospores. When released the basidiospores may infect new mustard plants, completing the life cycle.

Habitat dan peran ekologis

Puccinia monoica adalah jamur karat parasit dari genus Puccinia that menghambat mekar di tanaman tuan rumah (biasanya Boechera species) dan secara radikal mengubah morfologi tuan rumah untuk memfasilitasi reproduksi seksualnya sendiri dengan menghasilkan struktur yang mirip bunga tetapi mengandung partikel jamur bukan serbuk sari.

Reproduksi

Puccinia monoica is a parasitic rust fungus of the genus Puccinia that inhibits flowering in its host plant (usually a Boechera species) and radically transforms host morphology in order to facilitate its own sexual reproduction by producing structures resembling flowers but containing fungal particles instead of pollen. Infection of host plants (including Boechera and several other members of the mustard family) occurs via wind-borne basidiospores in late summer. Upon germination of the spores, fungal hyphae penetrate the stem of the mustard plant and siphon off nutrients. However, in order to reproduce sexually, the fungus must facilitate the transfer of spermatia from the spermatogonia on this plant to receptive hyphae borne in the spermatogonia on another infected mustard plant.
