Cyto-architecture of Byblis glands and leaf cells based on freeze-substitution and conventional TEM.

ABSTRACT:

Background and aims

Byblis liniflora (Byblidaceae) is a carnivorous plant that has developed sticky flypaper traps with two types of glandular trichomes producing digestive enzymes and sticky mucilage. This study aimed to analyse the ultrastructure of these glandular leaf trichomes based on rapid freeze-fixation and conventional chemical fixation in the attempt to understand their functional contribution to the carnivorous performance of the plants.

Methods

The Byblis cells were studied in transmission electron microscopy, scanning electron microscopy and scanning transmission electron microscopy using cryo-techniques for fixation and substitution in addition to conventional chemical fixation.

Key results

We show in detail the architecture of both the digestive glands
