Since the discovery in its cell walls of mixed-linkage glucans previously only found in Poales, Equisetum has received a lot of attention. Leroux et al. show that the carinal canals in E. ramosissimum have a distinctive lining containing pectic homogalacturonan, cellulose, xyloglucan and extensin. They propose that these canals function as water-conducting channels and that extensins play important roles in their development and/or function.
Scientists share viewpoints on the role of glycoproteins in cell wall network
Extensins are hydroxyproline-rich glycoproteins thought to strengthen the plant cell wall, one of the first barriers against pathogens, through intra- and intermolecular cross-links. The glycan moiety of extensins is...
The obturator bridges the downward transit of the pollen tube through style to ovary in many angiosperms. Examining pollen tube growth kinetics in the pistil in Malus × domestica and relating these to changes occurring...
