Sexual reproduction requires close proximity of mates, but ensures genetic variation in the local population. Although independent of cross-pollination, asexual reproduction can however, reduce genetic

In Grime’s C-S-R strategy model, plant ecological strategies vary between ruderals (R), stress-tolerators (S) and competitors (C). These variations are assumed to

Refugia are island-like habitats that are linked to long-term environmental stability and, as a result, high endemism. Conservation of refugia and endemism hotspots should

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

In the pantropical eudicot genus Begonia (Begoniaceae), non-contiguous clusters of helicocytic stomata develop from an inwardly spiralling series of amplifying divisions and secondary meristemoids that

The production of a new lateral root from parental root primary tissues has been investigated extensively, and the most important regulatory mechanisms are now well known.

As they push their way through the soil, roots are continuously exposed to mechanical pressure. This often results in their morphological modification. Most obvious are changes

The DER1 (deformed root hairs1) locus encodes a major vegetative actin (ACTIN2) in Arabidopsis thaliana. Mutations in DER1 lead to impaired root hair development. However, the

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

Mountain forests are important ecosystems subject to extreme climate conditions. Soil buffers root systems against variations in the weather, but we know little of how climate
