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.

Metabolic responses to combined water deficit and salt stress in maize primary roots

Journal of Integrative Agriculture, 2021
Soil water deficit and salt stress are major limiting factors of plant growth and agricultural productivity. The primary root is the first organ to perceive the stress signals for drought and salt stress.

The roles of microRNAs in regulating root formation and growth in plants

Journal of Integrative Agriculture, 2022
MicroRNAs (miRNAs) are small (ca. 20–24 nucleotides) non-coding RNAs that have recently been recognized as key post-transcriptional modulators of gene expression; and they are involved in many biological processes in plants, such as root growth and ...

Different effects of aluminum toxicity on primary roots of two barley cultivars with different aluminum-tolerance

浙江大学学报. 农业与生命科学版, 2018
To reveal the biological role of aluminum (Al)-tolerant mechanism in barley Al toxicity, the Altolerant cultivar Humai 8 and Al-sensitive cultivar Shengxian awnless six-rowed barley (Shengxian 6) were used as experimental materials, and treated with ...

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

Frontiers 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 ...

The involvement of auxin in root architecture plasticity in Arabidopsis induced by heterogeneous phosphorus availability

Biologia Plantarum, 2013
Homogeneous low phosphorus availability was reported to regulate root architecture in Arabidopsis via auxin, but the roles of auxin in root architecture plasticity to heterogeneous P availability remain unclear.
