Sporogenesis and Toxin a Production by Clostridium Difficile [PDF]
Journal of Medical Microbiology, 1986 The kinetics of spore production by Clostridium difficile were not paralleled by release of C. difficile toxin A in vitro. Toxin A was not found to be associated with either purified whole spores or spore coats. Residual traces of toxin A detected in spore contents were almost certainly derived from contaminating vegetative cell debris.

SEXUAL STERILITY is Essential for Both Male and Female Gametogenesis in Tomato [PDF]
, 2017 Gametogenesis is a key step in the production of ovules or pollen in higher plants. The molecular aspects of gametogenesis are well characterized in the model plant Arabidopsis; however, little information is known in tomato, which is a model plant for ...
