Effects of Elevated Temperature on Root System Development of Two Lupine Species

Plants, 2022
The aim of this study was to assess the effect of elevated temperature on the growth, morphology and spatial orientation of lupine roots at the initial stages of development and on the formation of lupine root architecture at later stages.

Ultraviolet-B Radiation Represses Primary Root Elongation by Inhibiting Cell Proliferation in the Meristematic Zone of Arabidopsis Seedlings

Frontiers in Plant Science, 2022
In Arabidopsis thaliana plants, exposure to UV-B induces an inhibition of primary root elongation. Different mutants have been isolated that are deficient in this response; however, little is known about the cellular and molecular mechanisms that ...

DUF1005 Family Identification, Evolution Analysis in Plants, and Primary Root Elongation Regulation of CiDUF1005 From Caragana intermedia

Frontiers in Genetics, 2022
Proteins with a domain of unknown function (DUF) represent a number of gene families that encode functionally uncharacterized proteins in eukaryotes. In particular, members of the DUF1005 family in plants have a 411-amino-acid conserved domain, and this ...

Integrative Roles of Phytohormones on Cell Proliferation, Elongation and Differentiation in the Arabidopsis thaliana Primary Root

Frontiers in Plant Science, 2021
The growth of multicellular organisms relies on cell proliferation, elongation and differentiation that are tightly regulated throughout development by internal and external stimuli.

Abiotic factors determine the root system architecture – review and update

Acta Societatis Botanicorum Poloniae, 2023
Decades of root research have led to a deep understanding of the molecular and genetic mechanisms regulating root system architecture. This review provides past and present-day root research with a focus on abiotic factors, such as nutrient limitation ...

Primary Root and Mesocotyl Elongation in Maize Seedlings: Two Organs with Antagonistic Growth below the Soil Surface

Plants, 2021
Maize illustrates one of the most complex cases of embryogenesis in higher plants that results in the development of early embryo with distinctive organs such as the mesocotyl, seminal and primary roots, coleoptile, and plumule.

The Arabidopsis Root Tip (Phospho)Proteomes at Growth-Promoting versus Growth-Repressing Conditions Reveal Novel Root Growth Regulators

Cells, 2021
Auxin plays a dual role in growth regulation and, depending on the tissue and concentration of the hormone, it can either promote or inhibit division and expansion processes in plants.

Root traits of common bean genotypes used in breeding programs for disease resistance Características de raízes de genótipos de feijão usados em programas de melhoramento para resistência a doenças

Pesquisa Agropecuária Brasileira, 2008
The objective of this work was to assess root traits of 19 common bean genotypes, used in breeding programs for disease resistance. Genotypes DOR 364 and G 19833 were used as deep and shallow basal root checks, respectively.

Gravity Signaling in Flowering Plant Roots

Plants, 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 ...

Comparative Proteomic Analysis Provides New Insights Into Low Nitrogen-Promoted Primary Root Growth in Hexaploid Wheat

Frontiers in Plant Science, 2019
Nitrogen deficient environments can promote wheat primary root growth (PRG) that allows for nitrogen uptake in deep soil. However, the mechanisms of low nitrogen-promoted root growth remain largely unknown.
