Overview

Research examines anatomical features of Cecidomyiidae galls in Pleopeltis minima, indicating adaptations for desiccation tolerance.

Key Points

  • This study aims to investigate the anatomical and histochemical features of galls in the poikilohydric fern Pleopeltis minima.
  • Examined non-galled pinnae (NGP) and galled pinnae (GP) of Pleopeltis minima
  • Analyzed samples from anatomical, histochemical, and histometrical perspectives
  • Compared features related to poikilohydry in gall and non-gall tissues
  • Galled pinnae exhibited larger peltate scales than non-galled pinnae
  • Galls featured thickened, pectin-rich walls aiding in water absorption and retention
  • Nutritive cells surrounding galls accumulated phenolics to mitigate free radical damage
