Sequential Deposition and Remodeling of Cell Wall Polymers During Tomato Pollen Development

open access: yesFrontiers in Plant Science, 2021
The cell wall of a mature pollen grain is a highly specialized, multilayered structure. The outer, sporopollenin-based exine provides protection and support to the pollen grain, while the inner intine, composed primarily of cellulose, is important for ...

Pollen grains for oral vaccination [PDF]

open access: yesJournal of Controlled Release, 2014
Oral vaccination can offer a painless and convenient method of vaccination. Furthermore, in addition to systemic immunity it has potential to stimulate mucosal immunity through antigen-processing by the gut-associated lymphoid tissues. In this study we propose the concept that pollen grains can be engineered for use as a simple modular system for oral ...
