Cover Story: The pectin-rich plant cell wall defines cell structure and facilitates cell adhesion. A screen of mutant Arabidopsis hypocotyls identified a new allele of QUASIMODO2 (QUA2), a gene required for pectin accumulation and cell adhesion. A suppressor of qua2 was isolated and describes a null allele of SABRE (SAB), which encodes a previously described plasma membrane protein required for longitudinal cellular expansion that organizes the tubulin cytoskeleton. sab mutants have increased pectin content, increased levels of Pectin Methyl Esterases, Extensins, Arabinogalactan Proteins, and reduced cell surface area relative to qua2 and WT, contributing to a restoration of cell adhesion. Thus, the tubulin cytoskeleton influences the accumulation of cell wall pectin, proteins, and cell adhesion. View this paper

  • Frans J. M. Maathuis

20 April 2021

Drought stress reduces annual global wheat yields by 20%. Silicon (Si) fertilisation has been proposed to improve plant drought stress tolerance. However, it is currently unknown if and how Si affects different wheat landraces, especially with respec...

  • Jonathan Marescaux and
  • Jill K. Olofsson

20 April 2021

The genus Mentha is taxonomically and phylogenetically challenging due to complex genomes, polyploidization and an extensive historical nomenclature, potentially hiding cryptic taxa. A straightforward interpretation of phylogenetic relationships with...
