Lateral root emergence: a difficult birth [PDF]

Journal of Experimental Botany, 2009
Lateral root initiation takes place deep within the parental root, requiring new primordia to break through the overlying tissues before they emerge into the soil. Lateral root emergence has been well described at the cellular level but, until recently, the molecular mechanisms involved were unclear.

RALFL34 regulates formative cell divisions in Arabidopsis pericycle during lateral root initiation [PDF]

, 2016
We describe the role of RALFL34 during early events in lateral root development, and demonstrate its specific importance in orchestrating formative cell divisions in the pericycle.In plants, many signalling molecules, such as phytohormones, miRNAs ...

GOLVEN peptide signalling through RGI receptors and MPK6 restricts asymmetric cell division during lateral root initiation [PDF]

, 2020
During lateral root initiation, lateral root founder cells undergo asymmetric cell divisions that generate daughter cells with different sizes and fates, a prerequisite for correct primordium organogenesis.

Root isoprene formation alters lateral root development [PDF]

Plant, Cell & Environment, 2020
AbstractIsoprene is a C5 volatile organic compound, which can protect aboveground plant tissue from abiotic stress such as short‐term high temperatures and accumulation of reactive oxygen species (ROS). Here, we uncover new roles for isoprene in the plant belowground tissues. By analysing Populus x canescens isoprene synthase (PcISPS) promoter reporter

Lateral Roots: Random Diversity in Adversity [PDF]

Trends in Plant Science, 2019
Lateral roots are essential for soil foraging and uptake of minerals and water. They feature a large morphological diversity that results from divergent primordia or root growth and development patterns. Besides a structured diversity, resulting from the hierarchical and developmental organization of root systems, there exists a random diversity ...

Arabidopsis lectin EULS3 is involved in ABA signaling in roots [PDF]

, 2020
The Arabidopsis thaliana lectin ArathEULS3 is upregulated in particular stress conditions and upon abscisic acid (ABA) treatment. ABA is a plant hormone important for plant growth and stress responses.

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

, 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

Auxin-dependent cell cycle reactivation through transcriptional regulation of Arabidopsis E2Fa by lateral organ boundary proteins [PDF]

, 2011
Multicellular organisms depend on cell production, cell fate specification, and correct patterning to shape their adult body. In plants, auxin plays a prominent role in the timely coordination of these different cellular processes. A well-studied example

Nitrogen forms affect root structure and water uptake in the hybrid poplar [PDF]

, 2011
The study analyses the effects of two different forms of nitrogen fertilisation (nitrate and ammonium) on root structure and water uptake of two hybrid poplar (Populus maximowiczii x P. balsamifera) clones in a field experiment.
