Parasporal bodies of Bacillus laterosporus sporangia [PDF]

open access: yesJournal of Bacteriology, 1990
Intact colonies of Bacillus laterosporus examined by thin-section transmission electron microscopy revealed sporangia in various stages of development and degeneration as the endospores matured. The sporangia formed a surface layer of hexagonally arranged subunits. The variety of parasporal bodies raised questions of developmental and ecologic utility.

Phytophthora infestans Sporangia Produced in Culture and on Tomato Leaflet Lesions Show Marked Differences in Indirect Germination Rates, Aggressiveness, and Global Transcription Profiles

open access: yesMolecular Plant-Microbe Interactions, 2019
Sporangia of Phytophthora infestans from pure cultures on agar plates are typically used in lab studies, whereas sporangia from leaflet lesions drive natural infections and epidemics.

Phytophthora infestans Sporangia Produced in Artificial Media and Plant Lesions Have Subtly Divergent Transcription Profiles but Equivalent Infection Potential and Aggressiveness

open access: yesMolecular Plant-Microbe Interactions, 2019
Sporangia of the potato late blight agent Phytophthora infestans are often used in studies of pathogen biology and plant responses to infection. Investigations of spore biology can be challenging in oomycetes because their sporangia are physiologically ...

Development of detection systems for the sporangia of Peronospora destructor [PDF]

open access: yes, 2008
A monoclonal antibody that recognises components of the wall of sporangia of Peronospora destructor was raised. Tests using spores of higher fungi and other species of mildew demonstrated the specificity of the monoclonal.

Survival of sporangia from Plasmopara viticola, the downy mildew of grapevine [PDF]

open access: yes, 2015
Research NoteThe potential of aged sporangia from Plasmopara viticola to produce zoospores as a requirement to form new infections was determined. Sporangia were produced on potted grapevines and kept on the vines at 22 °C, 30 % r.h.

PpMID1 Plays a Role in the Asexual Development and Virulence of Phytophthora parasitica

open access: yesFrontiers in Microbiology, 2017
Phytophthora parasitica is a notorious oomycete pathogen that causes severe disease in a wide variety of crop species. Infection of plants involves mainly its asexual life stage, including papillate sporangia and biflagellated zoospores, which are the ...
