The guanine nucleotide exchange factor RIC8 regulates conidial germination through Gα proteins in Neurospora crassa. [PDF]

open access: yes, 2012
Heterotrimeric G protein signaling is essential for normal hyphal growth in the filamentous fungus Neurospora crassa. We have previously demonstrated that the non-receptor guanine nucleotide exchange factor RIC8 acts upstream of the Gα proteins GNA-1 and

Spore Morphology and Taxonomy of Polypodiaceae [PDF]

open access: yesGrana, 1970
Abstract The examination of spores belonging to eight species representing five genera of Polypodiaceae reveals that they are typically free, anisopolar and monolete (bilateral). In a majority of cases the spores are yellow and have a short laesura—about half the length of the greater equatorial axis of the spore.
