Rapid assessment of fern spore quality using microscale electrical conductivity testing

Applications in Plant Sciences, Volume 14, Issue 5, September-October 2026.
Abstract Premise Ex situ spore banks are essential for fern conservation and research, yet traditional germination tests for assessing spore quality are time consuming and labor intensive. We explored whether electrical conductivity (EC), a rapid proxy for seed vigor, could offer an efficient alternative for evaluating fern spore quality. Methods Using

Involvement of an orphan response regulator of the two-component regulatory system in the formation of physiologically mature sporangia in Actinoplanes missouriensis

Microbiology Spectrum
The actinomycete Actinoplanes missouriensis forms terminal sporangia that contain dormant sporangiospores. Upon contact with water, sporangia release zoospores through a process called sporangium dehiscence.
