Cell-wall pectin and Al resistance
Aluminium (Al) toxicity is one of the factors limiting crop production on acid soils and various resistance mechanisms have evolved in plant species. Cell-wall pectin content is generally lower in Al-resistant than in...

Helical cell wall thickenings in Aspleniaceae
Helical cell wall thickenings in Aspleniaceae Extraxylary helical cell wall thickenings (HCWTs) in vascular plants are not well documented. Leroux et al. study their occurrence and composition in the root cortex of the...
