(A) Root system architecture is concerned with structural features of the root and responds to with environmental stimuli. (B) The rhizosphere produces photosynthetically fixed carbon that exudes into the soil and influences soil physicochemical gradients. (C) Free-living or parasitic nematodes interact with the rhizosphere via signaling ...
The rhizosphere is the thin area of soil immediately surrounding the root system. It is a densely populated area in which the roots compete with invading root systems of neighboring plant species for space, water, and mineral nutrients as well as form positive and negative relationships with soil-borne microorganisms such as bacteria, fungi and insects.
The xylem system is seen to develop in this zone along with lateral root development. Elongation Zone: Cells in this stage are rapidly elongating and parts of the phloem system (sieve tubes) start to develop. As you move up closer to the maturation zone, cell division and, elongation decrease. Meristematic Zone: Right above the root cap and ...
A true root system consists of a primary root and secondary roots (or lateral roots). the diffuse root system: the primary root is not dominant; the whole root system is fibrous and branches in all directions. Most common in monocots. The main function of the fibrous root is to anchor the plant.

Root architecture refers to the spatial configuration of a plant's root system. The root architecture plays an important role in acquiring a secure supply of water and nutrients, as the acquisition of these resources drives plant growth. [1] In addition to nutrient absorption, the root architecture provides a plant with anchorage and support.

The geometric and arithmetic analysis of architecture was a popular subject of 19th-century scholarship, but diminished to a backwater of medieval studies; this book represents something of a revival of the topic, [7] following earlier work in the mid-20th century by Otto von Simson []. [6]
