little or no cuticle (offering minimum resistance for oxygen diffusion) and dense cytoplasm studded with mitochondria at Ule tip of the root hairs, are some of the special ultrastructural adaptations of root hairs which offer an indication that at least one of their main functions involves ...
Without roots there would be no rhizosphere and no rhizodeposition to fuel microbial activity. Although micro-organisms may view roots merely as a source of carbon supply this belies the fascinating complexity and diversity of root systems that occurs despite their common function. Here, we examine ...
One of the most striking features of the plant root hair cell tissue specimen is its microscopic structure. Under the microscope, the intricate network of root hairs and their associated cells becomes apparent, highlighting the specialized adaptations that enable these cells to effectively absorb water...

2Roots, root systems, and root biotic colonization 2.1What is a root? Roots are one of the earliest adaptations that enabled plants to colonize land (Kenrick & Crane, 1997). They perform essential functions necessary for the survival and development of plants, such as anchoring them to a subs...
1). The LP stress promoted lateral root development and root hair elongation26, and the increase in root surface area should facilitate better nutrient uptake from the soil27. Previously, it was claimed that phosphorus-efficient varieties improved phosphorus uptake by increasing the number and size ...
Since the top part of soils is often richer in phosphorus, adaptations of root architecture that increase root density in the upper parts of the soil favor phosphorus-uptake efficiency. This is achieved by a shallower growth angle of axial roots, leading to a greater length of roots in the ...
Cluster 1 contained genes with highest expression in the root tip of the cluster root and decreasing towards the mature part. GO term analysis identified that this cluster was enriched for genes with functions in cell cycle regulation and auxin-mediated growth control. By contrast, genes in ...
Environmental stresses as major threats to global food security in the twenty-first century and improving biomass production and seed yield per area of crop plants become very critical. Plants are sessile organisms that cannot escape from environmental c
The rhizosphere is the soil volume at the root-soil interface that is under the influence of the plant roots and the term was introduced by Hiltner in 1904 (Brimecombe et al. 2001). Microbial population in the rhizosphere has continuous access to a flow of low and high molecular weight or...
