Auxin-Cytokinin Balance Shapes Maize Root Architecture by Controlling Primary Root Elongation and Lateral Root Development

open access: yesFrontiers in Plant Science, 2022
The root system is responsible for water and nutrients uptake from the soil, and therefore, its extension is basic for an efficient acquisition. The maize root system is formed by different types of roots, and the lateral root branching substantially ...

Single-rooted primary first molars

open access: yesIndian Journal of Dental Research, 2012
Knowledge regarding the morphological variations in roots and root canals aids in successful dental treatment. However, literature regarding dysmorphology of roots in primary dentition is sparse. The purpose of this article is to present a case of bilateral primary mandibular first molars with an unusual morphology of single root.

OsGatB, the subunit of tRNA-dependent amidotransferase, is required for primary root development in rice

open access: yesFrontiers in Plant Science, 2016
A short-root rice mutant was isolated from an ethyl methane sulfonate-mutagenized library. From map-based cloning strategy, a point mutation, resulting in an amino acid change from proline to leucine, was identified in the fourth exon of a glutamyl-tRNA (

Gravity Signaling in Flowering Plant Roots

open access: yesPlants, 2020
Roots typically grow downward into the soil where they anchor the plant and take up water and nutrients necessary for plant growth and development. While the primary roots usually grow vertically downward, laterals often follow a gravity set point angle ...

Stomata on the Primary Root of Ceratonia siliqua

open access: yesAnnals of Botany, 1987
Anomocytic stomatal complexes observed with light and scanning electron microscopes on the primary roots of Ceratonia siliqua (carob tree) are described. Stornata are randomly distributed throughout the surface of the root zones which possess mature vascular tissues, i.e. from the zone of root hairs to the transition zone. Stomatal orientation does not

Insight into the early steps of root hair formation revealed by the procuste1 cellulose synthase mutant of Arabidopsis thaliana [PDF]

open access: yes, 2008
Background: formation of plant root hairs originating from epidermal cells involves selection of a polar initiation site and production of an initial hair bulge which requires local cell wall loosening. In Arabidopsis the polar initiation site is located
