Aquaporins and apoplastic barriers in nutrient-limited barley
Aquaporins can change their activity reversibly, if exposed to a change in nutrients.

Water balance in potassium-limited barley
Limited supply of mineral nutrients such as potassium increases the root-to-shoot ratio. This also increases the ratio between water-absorbing and -losing plant surface. Water uptake per unit surface has to either...

Root hair abundance impacts cadmium accumulation in Arabidopsis thaliana shoots
Root hairs increase the contact area of roots with soil and thereby enhance the capacity for solute uptake. The strict hair/non-hair pattern of Arabidopsis thaliana can change with nutrient deficiency or exposure to...
Lateral root initiation and formation in Cucurbita pepo: is auxin a key player?
In most plant species, initiation of lateral roots occurs above the elongation zone. However, in Cucurbitaceae it takes place in the parental root meristem. Ilina et al. investigate the first cellular events leading to...
SLAD: Subero-lignified apical deposit in the root tip
Morphological response of radish (Raphanus sativus, Brassicaceae) roots exposed to toxic concentration of copper (Cu) include many root growth changes. Kováč et al. find that such changes are coupled with the formation...
Apoplastic barriers in maize lateral roots
Roots rely on apoplastic barriers for nutrient absorption. However, little is known about the establishment of these barriers within the lateral roots. The branching, permeability of the outer cell layers and...

Asymmetrical root development as a reaction to abiotic stresses
Roots can develop resilience and protective barriers to drought and cadmium-induced (Cd) stress. Líška et al. study the ways in which the vascular tissues of roots develop characteristics to mitigate the effects of...
Cadmium translocation by contractile roots
Contractile roots require specific anatomical adaptation of the root base, with less-lignified & less-suberized tissues than in the subapical root.
Lignin and/or suberin? Lignin!
For as long as the Casparian strip (CS) – an impervious component of the endodermal cell wall that blocks the passive flow of water and solutes into the vascular tissues of a plant – has been known (discovery credited...

Plant cell biology in the frame!
Notwithstanding the centuries we’ve spent peering at, poking, prodding and penetrating the inner workings of plant cells with various types of microscopes and decades undertaking investigations at the sub-cellular...
