Plant cell walls constitute the extracellular matrix surrounding plant cells and are composed mainly of polysaccharides. The chemical makeup of the primary plant cell wall, and specifically, the abundance, localization and arrangement of the constituting polysaccharides are intimately linked with growth, morphogenesis and differentiation in plant cells. Visualization of the cell wall components is,...
The role of reactive oxygen species (ROS) during pollen tube growth has been well established, but its involvement in the early germination stage is poorly understood. ROS production has been reported in germinating tobacco pollen, but evidence for a clear correlation between ROS and germination success remains elusive. Here, we show that ROS are involved in germination and pollen tube formation in...
