Ciri dan struktur

Cronartium ribicola has two obligate hosts: Pinus spp and Ribes spp. Five-needle pines (Pinus spp.) are infected in the fall by basidiospores that have spread under cool, moist conditions from the alternate host, currants and gooseberries (Ribes spp.), and germinated on needles to enter with germ tubes through open stomata. Young pines are most susceptible and will die at faster rates following infection. Once spermatia have fertilized receptive hyphae in the Pinus spp. host, aecia are formed within a year, appearing as white blisters before rupture reveals the orange or yellow aeciospores within. The wind-blown aeciospores infect Ribes spp. and the fungus quickly develops uredia in less than a few weeks. Uredospores produced in this stage spread to infect other parts of the same host or other Ribes spp. hosts in the area. Next, telia are developed on the abaxial (lower) surface of leaves, where teliospores germinate to give rise to basidiospores that will complete the disease cycle by infecting Pinus spp. hosts. As is common among rusts, the life cycle of Cronartium ribicola includes two host species and goes through five spore stages. This life cycle is termed heteroecious. In the specific case of Cronartium ribicola, the aecial host of this pathogen is the white pine (Pinus subgenus Strobus, family Pinaceae) and the telial hosts are those of the genus Ribes, specifically currants and gooseberries. Species of both telial and aecial hosts have varying levels of resistance or immunity to infection. Environmentally, Cronartium ribicola prefers cooler temperatures coupled with moist conditions in low-lying areas, especially during the late summer and early fall.

Habitat dan peran ekologis

Seperti biasa di antara rusa, siklus hidup Cronartium ribicola mencakup dua spesies tuan rumah dan melewati lima tahap spora. Siklus hidup ini disebut heterocious. Dalam kasus khusus Cronartium ribicola, inang easial patogen ini adalah pinus putih (Pinus subgenus Strobus, keluarga Pinaceae) dan inang telial adalah mereka dari genus Ribes, khususnya kurant dan gooseberry. Species of baik hos telial dan aecial memiliki tingkat resistensi atau kekebalan terhadap infeksi yang berbeda. Pada inang aecial, tanda-tanda pertama C. ribicola adalah bintik-bintik kuning atau merah pada Pinus needles, tetapi ini kecil dan dapat sulit dilihat; gejala yang lebih terlihat pada inang aecial termasuk kanker abadi yang muncul di cabang dalam dua tahun setelah infeksi. Looking at tanaman yang terinfeksi secara keseluruhan, Pinus will tampak klorot, dan terhambat dengan cabang mati atau puncak yang berubah warna merah terang. Di sisi lain, inang telial, Ribes, dapat menyumbat bintik-bintik daun klorot kuning, tetapi tidak terpengaruh secara signifikan. Tanda-tanda C. ribicola pada Ribes, datang dalam bentuk patogen itu sendiri sebagai pustules oranye di bagian bawah daun.

Species of both telial and aecial hosts have varying levels of resistance or immunity to infection. On the aecial host, the first signs of C. ribicola are yellow or red spots on the Pinus needles, but these are small and can be difficult to see; more visible symptoms on the aecial host includes perennial cankers which appear on the branches within two years of infection. Looking at the infected plant as a whole, the Pinus will appear chlorotic, and stunted with dead branches or tops that turn a bright red color. On the other hand, the telial host, Ribes, can contract yellowish chlorotic leaf spots, but is otherwise not significantly impacted. The signs of C. ribicola on Ribes, come in the form of the pathogen itself as orange pustules on the underside of the leaf.
