  • The telial stage of heteroecious parasitic fungi is spent on the secondary host plant.
  • His studies of what has since been known as plant-parasitic fungi are heteroecious.
  • "Puccinia graminis " is a macrocyclic heteroecious fungus that causes wheat stem rust disease.
  • Host restriction may, in heteroecious species, apply to both phases of life cycle or to only one phase.
  • A primary aecial stage is spent parasitizing a separate host plant which is a precursor in the life cycle of heteroecious fungi.
  • They are heteroecious rusts with two alternating hosts, typically a pine and a flowering plant, and up to five spore stages.
  • "' The Telial stage "'is one of the stages in the life cycle of a parasitic heteroecious fungus.
  • Brefeld was a prolific author of works in the field of mycology, being remembered for his writings on the heteroecious nature of smuts.
  • Since this pathogen is a heteroecious rust, " C . arctostaphyli " has a primary and an alternate host upon which it produces different fruiting structures and different spores unique to each structure.
  • In heteroecious species, the aphids spend winter on tree or bush primary hosts; in summer, they migrate to their secondary host on a herbaceous plant, then the gynoparae return to the tree in autumn.
  • The heteroecious lifecycle ( which is mainly linked to consumption of angiosperms and represents 10 % of all aphids ) is believed to have evolved from the ancestral autoecious form ( on conifers ); this is believed to have reverted to the ancestral form in some species that were once heteroecious.

  • Similar galls are produced by other aphids : on Sitka spruce, by the Cooley spruce gall adelgid, " Gilletteela cooleyi ", some generations of which migrate to Douglas fir ( " Pseudotsuga taxifolia " ); and on spruce by " Cnaphalodes sp " ., which is heteroecious with larch.
  • While the predominant hypothesis is that " H . vastatrix " is heteroecious, completing its life cycle on an alternate host plant which has not yet been found, an alternative hypothesis is that " H . vastatrix " actually represents an early-diverging autoecious rust, in which the teliospores are non-functional and vestigial, and the sexual life cycle is completed by the urediniospores.
  • In macrocyclic and demicyclic life cycles, the rust may be either host alternating ( heteroecious ), i . e ., the aecial state is on one kind of plant but the telial state on a different and unrelated plant, or non-host alternating ( autoecious ), i . e ., the aecial and telial states on the same kind of plant . "'Heteroecious "'rust fungi require two unrelated hosts to complete their life cycle, with the primary host being infected by aeciospores and the alternate host being infected with basidiospores.
