The Root Cap Cuticle: A Cell Wall Structure for Seedling Establishment and Lateral Root Formation.

open access: yesCell, 2019
The root cap surrounding the tip of plant roots is thought to protect the delicate stem cells in the root meristem. We discovered that the first layer of root cap cells is covered by an electron-opaque cell wall modification resembling a plant cuticle ...

Auxin-dependent control of a plasmodesmal regulator creates a negative feedback loop modulating lateral root emergence

open access: yesNature Communications, 2020
Lateral roots originate from initial cells deep within the main root and must emerge through several overlying layers. Lateral root emergence requires the outgrowth of the new primordium (LRP) to coincide with the timely separation of overlying root ...

Cell Type-Specific Transcriptomics of Lateral Root Formation and Plasticity

open access: yesFrontiers 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,

A shared gene drives lateral root development and root nodule symbiosis pathways in Lotus

open access: yesScience, 2019
Common gene yields different structures Nodules form on legume roots to house symbiotic, nitrogen-fixing bacteria. Lateral roots, characteristic of a much broader range of plants, extend to take up nutrients and water from the soil. Soyano et al.

Flavonols modulate lateral root emergence by scavenging reactive oxygen species in Arabidopsis thaliana

open access: yesbioRxiv, 2020
Flavonoids are plant-specific antioxidant compounds that modulate plant development, which include flavonols and anthocyanins subclasses. In Arabidopsis thaliana, mutants in genes encoding each step in the flavonoid biosynthetic pathway have been ...

Fine control of aerenchyma and lateral root development through AUX/IAA- and ARF-dependent auxin signaling

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2019
Significance Aerenchyma formation has a crucial role in conferring abiotic stress tolerance to plants, including agronomically important crops. In rice, root aerenchyma constitutively forms under aerobic conditions and is further induced under oxygen ...

Noncanonical auxin signaling regulates cell division pattern during lateral root development

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2019
Significance Development in multicellular organisms consists of a series of cell divisions followed by cell expansions, which are tightly controlled both spatially and temporally.

WOX-ARF modules initiate different types of roots

open access: yesCell Reports, 2023
Summary: Seed plants have evolved a complex root system consisting of at least three root types, i.e., adventitious roots, lateral roots, and the primary root. Auxin is the key hormone that controls the initiation of different root types.

UV‐B photoreceptor UVR8 interacts with MYB73/MYB77 to regulate auxin responses and lateral root development

open access: yesEMBO Journal, 2019
The UV‐B photoreceptor UVR8 mediates multiple UV‐B responses in plants, but the function of UVR8 in regulating root development has not previously been investigated.

Lateral root emergence: a difficult birth [PDF]

open access: yesJournal 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.
