Stable expression of aquaporins and hypoxia-responsive genes in adventitious roots are linked to maintaining hydraulic conductance in tobacco (Nicotiana tabacum) exposed to root hypoxia.

open access: yesPLoS ONE, 2019
Formation of adventitious roots in plants is a common response to hypoxia caused by flooding. In tobacco, after one week of root hypoxia treatment, plants produced twice as many adventitious roots as the aerated plants, but their maximum length was ...

Validation and refinement of allometric equations for roots of northern hardwoods [PDF]

open access: yes, 2007
The allometric equations developed by Whittaker et al. (1974. Ecol. Monogr. 44: 233–252), at the Hubbard Brook Experimental Forest have been used to estimate biomass and productivity in northern hardwood forest systems for over three decades.

Tonoplast Aquaporins Facilitate Lateral Root Emergence [PDF]

open access: yesPlant Physiology, 2016
Aquaporins (AQPs) are water channels allowing fast and passive diffusion of water across cell membranes. It was hypothesized that AQPs contribute to cell elongation processes by allowing water influx across the plasma membrane and the tonoplast to maintain adequate turgor pressure. Here, we report that, in Arabidopsis (Arabidopsis thaliana), the highly

Mechanical adaptations of cleavers (Galium aparine) [PDF]

open access: yes, 2004
• Background and Aims Cleavers (Galium aparine) is a fast-growing herbaceous annual with a semi-self-supporting, scrambling-ascending growth habit. Mature plants often use upright species for support. It is common in hedgerows and on waste ground. This

Quantitative Analysis of Soil Sheath Distribution in Maize Root Systems

open access: yesPlant Production Science, 1999
The soil sheath (SS) distribution and its change with the passage of time in maize root systems were investigated. Maize seeds were planted in deep pots, and the roots were sampled at 2, 3, 4 and 6 weeks after sowing.

Asymmetric auxin distribution establishes a contrasting pattern of aerenchyma formation in the nodal roots of Zea nicaraguensis during gravistimulation

open access: yesFrontiers in Plant Science, 2023
Auxin distribution is essential for determining root developmental patterns. The formation of lateral roots and constitutive aerenchyma, which is a gas space developed through cell death, is regulated by auxin in rice (Oryza sativa).

Plasticity of Lateral Root Branching in Maize

open access: yesFrontiers in Plant Science, 2019
Extensively branched root systems can efficiently capture soil resources by increasing their absorbing surface in soil. Lateral roots are the roots formed from pericycle cells of other roots that can be of any type.

Nitrate and phosphate availability and distribution have different effects on root system architecture of Arabidopsis [PDF]

open access: yes, 2002
Plant root systems can respond to nutrient availability and distribution by changing the three-dimensional deployment of their roots: their root system architecture (RSA). We have compared RSA in homogeneous and heterogeneous nitrate and phosphate supply

Genetic regulation of lateral root development

open access: yesPlant Signaling & Behavior, 2022
Lateral roots (LRs) are an important part of plant root systems. In dicots, for example, after plants adapted from aquatic to terrestrial environments, filamentous pseudorhizae evolved to allow nutrient absorption. A typical plant root system comprises a primary root, LRs, root hairs, and a root cap.

Sugar Accumulation along the Seminal Root Axis, as Affected by Osmotic Stress in Maize: A Possible Physiological Basis for Plastic Lateral Root Development

open access: yesPlant Production Science, 2005
We assumed that allocation of photosynthate is one of the main factors that regulate lateral root development in root systems under water deficit conditions. Six-days-old maize seedlings were exposed to osmotic stress (-0.21 MPa). Then, the sugar content
