Role of Root Hairs and Lateral Roots in Silicon Uptake by Rice [PDF]

Plant Physiology, 2001
The rice plant (Oryza sativa L. cv Oochikara) is known to be a Si accumulator, but the mechanism responsible for the high uptake of Si by the roots is not well understood. We investigated the role of root hairs and lateral roots in the Si uptake using two mutants of rice, one defective in the formation of root hairs (RH2) and another in that of lateral

Variation in Root System Architecture Response to Arsenic during Establishment and Onset of Storage Root Formation in Two Sweetpotato (Ipomoea batatas L.) Cultivars

HortScience
The primary objective of this work was to generate species-specific information about root architectural adaptations to simulated natural levels of arsenic (As) during the establishment phase and onset of storage root formation in sweetpotato.

Tonoplast Aquaporins Facilitate Lateral Root Emergence [PDF]

Plant 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

Cell Type-Specific Transcriptomics of Lateral Root Formation and Plasticity

Frontiers in Plant Science, 2019
Lateral roots are a major determinant of root architecture and are instrumental for the efficient uptake of water and nutrients. Lateral roots consist of multiple cell types each expressing a unique transcriptome at a given developmental stage. Therefore,

Distribution Pattern of Root Nodules in Relation to Root Architecture in Two Leading Cultivars of Peanut (Arachis hypogaea L.) in Japan

Plant Production Science, 2006
To effectively utilize symbiotic nitrogen fixation, we examined the formation of root nodules along with root system development in two leading peanut cultivars in Japan, Chibahandachi and Nakateyutaka.

Plant strategy to adapt to life in water: peculiarities of root system organization in Sagittaria sagittifolia and Alisma plantago-aquatica (Alismataceae)

Ukrainian Botanical Journal
The roots of aquatic plants are known to grow continuously in the low-oxygen environment, frequently encountering hypoxia, a common environmental stress that affects plant growth.

Overexpression of the Soybean NAC Gene GmNAC109 Increases Lateral Root Formation and Abiotic Stress Tolerance in Transgenic Arabidopsis Plants

Frontiers in Plant Science, 2019
NACs are plant-specific transcription factors that have crucial roles in plant development and biotic and/or abiotic stress responses. This study characterized the functions of the soybean NAC gene GmNAC109 using an overexpression construct in ...

The impact of light and gravity on growth directions in a root system of Cucumis sativus L.

Acta Societatis Botanicorum Poloniae, 2011
While each individual root responds to such environmental factors as light or gravity the question arises how these reactions subordinate to the whole root system, which is supposed to maintain its primary functions.
