Sugar Accumulation along the Seminal Root Axis, as Affected by Osmotic Stress in Maize: A Possible Physiological Basis for Plastic Lateral Root Development

Plant Production Science, 2005
We assumed that allocation of photosynthate is one of the main factors that regulate lateral root development in root systems under water deficit conditions. Six-days-old maize seedlings were exposed to osmotic stress (-0.21 MPa). Then, the sugar content

Plastid translation is essential for lateral root stem cell patterning in Arabidopsis thaliana

Biology Open, 2018
The plastid evolved from a symbiotic cyanobacterial ancestor and is an essential organelle for plant life, but its developmental roles in roots have been largely overlooked.

Genetic regulation of lateral root development

Plant Signaling & Behavior, 2022
Lateral roots (LRs) are an important part of plant root systems. In dicots, for example, after plants adapted from aquatic to terrestrial environments, filamentous pseudorhizae evolved to allow nutrient absorption. A typical plant root system comprises a primary root, LRs, root hairs, and a root cap.

Lateral Root Primordium Morphogenesis in Angiosperms [PDF]

Frontiers in Plant Science, 2019
Morphogenetic processes are the basis of new organ formation. Lateral roots (LRs) are the building blocks of the root system. After LR initiation and before LR emergence, a new lateral root primordium (LRP) forms. During this period, the organization and functionality of the prospective LR is defined.

Root mediated uptake of Salmonella is different from phyto-pathogen and associated with the colonization of edible organs

BMC Plant Biology, 2018
Background Pre-harvest contamination of fruits and vegetables by Salmonella in fields is one of the causes of food-borne outbreaks. Natural openings like stomata, hydathodes and fruit cracks are known to serve as entry points.

Asymmetric auxin distribution establishes a contrasting pattern of aerenchyma formation in the nodal roots of Zea nicaraguensis during gravistimulation

Frontiers in Plant Science, 2023
Auxin distribution is essential for determining root developmental patterns. The formation of lateral roots and constitutive aerenchyma, which is a gas space developed through cell death, is regulated by auxin in rice (Oryza sativa).

Phototropism and Gravitropism in Lateral Roots of Arabidopsis [PDF]

Plant and Cell Physiology, 2002
Gravitropism and, to a lesser extent, phototropism have been characterized in primary roots, but little is known about structural/functional aspects of these tropisms in lateral roots. Therefore, in this study, we report on tropistic responses in lateral roots of Arabidopsis thaliana. Lateral roots initially are plagiogravitropic, but when they reach a

Combination of teg1 and our1 enhances total root length through preferential carbon allocation to lateral root growth in rice

Frontiers in Plant Science
Root system development is essential for water and nutrient acquisition but requires substantial carbon investment. Optimizing root architecture while minimizing carbon costs is therefore an important target for crop improvement. Here, we characterized a

Resorption of Lateral Incisors during Canine Eruption: Two Clinical Cases with Focus on Root Lengths and Heredity

Dental Hypotheses, 2016
Introduction: It is well-known that pressure from orthodontic appliance can provoke root resorption in dentitions with short roots. The purpose of this case report is to demonstrate two clinical cases with focus on root length in dentitions exposed due ...

Peach PpSnRK1 Participates in Sucrose-Mediated Root Growth Through Auxin Signaling

Frontiers in Plant Science, 2020
Sugar signals play a key role in root growth and development. SnRK1, as one of the energy centers, can respond to energy changes in plants and affect the growth and development of plants. However, studies on sugar signals and SnRK1 regulating root growth
