Histology of infection and sporulation by saprophytic cultures of Melampsora lini inoculated onto flax cotyledons in sterile culture

Franziska L. M. Turel Canadian Journal of Botany 1972. doi:10.1139/b72-030

Other claims from this paper (6)

Observation Rust mycelium invaded wounded flax cotyledon ends.
Observation Numerous haustoria indicated parasitism within four weeks.
Observation Uredosori formed mainly on thickened cotyledon parts by callus.
Observation Uredospores generally seemed to have two nuclei, though hard to observe.
Observation Teliosori formed infrequently, sometimes on cotyledons and older adventitious roots.
Observation Teliospores had one nucleus.

Title

Factors Affecting the Growth of Rust Fungi on Host Tissue Cultures

Ramesh Maheshwari; A. C. Hildebrndt Botanical Gazette 1967. doi:10.1086/336392

Other claims from this paper (13)

Observation Attempts to infect host tissue cultures with urediospores failed.
Observation Snapdragon cultures produced extracellular material inhibiting urediospore germination.
Observation The inhibitory material could be leached in agar or water.
Observation The inhibitory material was heat stable, dialysable, non-ionic, and insoluble in ether and ethanol.
Observation Some sunflower hypocotyl explants proliferated and produced roots, leaves and flowers on defined medium.
Observation Leaf callus was isolated from shoots developed in vitro.
Observation Sunflower leaf cultures and shoots could not be infected with Puccinia helianthi urediospores.
Observation Infected snapdragon culture developed aerial P. antirrhini mycelium.
Observation Aerial mycelium formed white tufts 1-3 mm long.
Observation Transferred mycelium did not continue growth on nutrient medium.
Observation The mycelium could not infect host tissue cultures.
Intervention effect Urediospore inoculation of epidermis covered snapdragon cultures did not produce infection.
Observation Contact with germinated urediospores failed to infect callus.
