Lateral root - Wikipedia
Lateral roots, emerging from the pericycle (meristematic tissue), extend horizontally from the primary root (radicle) and over time makeup the iconic branching pattern of root systems. [1] They contribute to anchoring the plant securely into the soil, increasing water uptake, and facilitate the extraction of nutrients required for the growth ...
Lateral Root - an overview | ScienceDirect Topics
Lateral roots are the building blocks of the root system that arises from pericycle and exhibit a morphology that is similar to the primary root (Dolan et al., 1993). These roots are important for expanding the contact area of root systems to explore heterogeneous soil environments.
Lateral root formation and the multiple roles of auxin
2017年7月20日 · The model plant Arabidopsis thaliana possesses a tap root system, in which the primary root and lateral roots (LRs) are major architectural determinants. The phytohormone auxin fulfils multiple roles throughout LR development.
Lateral Root | Parts of a Plant - Plant Biology
Lateral roots serve as the plant’s secure anchor to the soil and they extend horizontally from the primary root. Such branching of the root can help in the uptake of water and in facilitating the extraction of nutrients that is needed for the plant’s growth and development.
Lateral Root - an overview | ScienceDirect Topics
Lateral roots are anatomically identical to the primary root and produce tertiary roots. Their arrangement is less well ordered than the laterals. The tertiaries may themselves be branched, and the branching process may continue on.
Same same, but different: growth responses of primary and lateral roots ...
2020年1月20日 · Here, we review similarities and differences between primary and lateral root organ growth, and emphasize particularly how external stimuli and internal signals differentially integrate root system growth.
Lateral root | plant anatomy | Britannica
Because lateral roots are initiated in the pericycle and grow out through the cortex and epidermis, they are said to have an internal, or endogenous, origin, in contrast to the external, or exogenous, origin of leaves and the apical meristem of stems (see below Stems).
Adventitious roots and lateral roots: similarities and differences
Although a wide variety of root systems exist across different species, all plants have a primary root (derived from an embryonic radicle) and different types of lateral roots. Adventitious roots, by comparison, display the same functions as lateral roots but develop from aerial tissues.
Specification and evolution of lateral roots - Cell Press
2023年3月13日 · Lateral root branching relies on the de novo specification of a subset of founder cells (hereinafter referred to as lateral root stem cells) located in the internal tissues of an existing root. This step is followed by initiation, in which the specified cells re-enter the cell cycle, and subsequently by primordium formation and emergence.
Brief about lateral roots. - BYJU'S
Lateral roots are the smaller roots that emerge horizontally from the taproot or the main root. They are said to have an endogenous origin since they are produced from called pericycle. The pericycle is a thin layer of cells that is located between the vascular bundles and endodermis.
