Among European Neottieae, Limodorum abortivum is a common Mediterranean orchid. It forms small populations with a patchy distribution in woodlands, and is characterized by much reduced leaves, suggesting a partial mycoheterotrophy. We have investigated both the photosynthetic abilities of L . abortivum adult plants and the diversity of mycorrhizal fungi in Limodorum plants growing in different environments and plant communitie...

Granulocytes of the epigonal and Leydig organs of Rhizoprionodon lalandii were identified and classified into three different cell types, type I and type II eosinophils and neutrophils. The development of these cells in the haematopoietic tissues was dynamic, demonstrated by nuclear immunopositivity for the proliferating cell nuclear antigen (PCNA) proteins and was regulated by various cytokines, including the transforming gro...
