This review examines the key aspects of ion exchange and diffusion in plant root cell walls
and the implications of these processes for the uptake of mineral nutrients and water under …

It has only recently become apparent that the apoplast plays a major role in a diverse range
of processes, including intercellular signalling, plant–microbe interactions and both water …

During the development of Arabidopsis and other land plants, diffusion barriers are formed
in the apoplast of specialized tissues within a variety of plant organs. While the cuticle of the …

Expression of an inducible gene with sequences common to genes encoding pectin
methylesterase (PME) was found to be tightly correlated, both spatially and temporally, with …

The size and shape of leaves are influenced by the progression of the cell cycle arrest front
(AF). However, the AF progression with leaf growth has not been characterized …

Since the fundamental work of the botanist Ernst Munch there has been a clear
differentiation between a symplastic and an apoplastic compartment of plants, separated by …

To quantify the diffusion constant of small molecules in the plant cell wall, fluorescence from
carboxyfluorescein (CF) in the intact roots of Arabidopsis thaliana was recorded. Roots were …

Two functionally distinct sets of meristematic cells exist within root tips of pea (Pisum
sativum): the root apical meristem, which gives rise to the body of the root; and the root cap …

During a study of the diffusivity of sulphorhodamine G in the cortical apoplast of maize roots
widely discrepant rates were found between different samples. In roots which had …

The paper investigates how the apoplastic route of ion transfer is affected by the outermost
cortex cell layers of a primary root. Staining of hand-made cross sections with aniline blue in …
