Auxin Signaling Mediated Spatial Accommodation Mechanisms During Lateral Root Development. [PDF]

Physiol Plant
ABSTRACT Spatial accommodation, the ability of plant tissues to adapt structurally during organogenesis, is important for the successful growth and emergence of new organs, such as lateral roots, through overlying cell layers. This process requires precise coordination between cellular architecture and physical as well as biochemical signals.

Exodermis and endodermis are the sites of xanthone biosynthesis in Hypericum perforatum roots. [PDF]

New Phytologist, 2018
Summary Xanthones are specialized metabolites with antimicrobial properties, which accumulate in roots of Hypericum perforatum. This medicinal plant provides widely taken remedies for depressive episodes and skin disorders. Owing to the array of pharmacological activities, xanthone derivatives attract attention for drug design.

Root vacuolar sequestration and suberization are prominent responses of Pistacia spp. rootstocks during salinity stress

Plant Direct, 2021
Understanding the mechanisms of stress tolerance in diverse species is needed to enhance crop performance under conditions such as high salinity. Plant roots, in particular in grafted agricultural crops, can function as a boundary against external ...

Multi-Omics Analyses on Maya-Land Tomatoes Shed Light on Plant Strategies to Thrive in High Temperatures. [PDF]

Physiol Plant
ABSTRACT Heat stress limits tomato yield and quality. Deciphering the key genes and metabolites related to heat tolerance is essential for selecting tolerant varieties. In this study, we profiled the transcriptomes and metabolomes of roots and shoots in response to heat stress from a Maya‐land ecotype of heirloom tomato (Calkiní), which grows in ...

Analysis of aliphatic waxes associated with root periderm or exodermis from eleven plant species. [PDF]

Phytochemistry, 2015
Aliphatic waxes can be found in association with suberized tissues, including roots. Non-polar lipids were isolated by rapid solvent extraction of mature regions of intact roots from eleven angiosperms, including both monocots and dicots. The majority of roots analyzed were taproots or tuberous taproots that had undergone secondary growth and thus were

Rice OsCASP1 orchestrates Casparian strip formation and suberin deposition in small lateral roots to maintain nutrient homeostasis

Frontiers in Plant Science, 2022
Arabidopsis Casparian strip membrane domain proteins (CASPs) form a transmembrane scaffold to recruit lignin biosynthetic enzymes for Casparian strip (CS) formation.

Nitric oxide alleviates cadmium- but not arsenic-induced damages in rice roots [PDF]

, 2020
Nitric oxide (NO) has signalling roles in plant stress responses. Cadmium (Cd) and arsenic (As) soil pollutants alter plant development, mainly the root-system, by increasing NO-content, triggering reactive oxygen species (ROS), and forming peroxynitrite

Apoplastic histochemical features of plant root walls that may facilitate ion uptake and retention

Open Life Sciences, 2021
We used brightfield and epifluorescence microscopy, as well as permeability tests, to investigate the apoplastic histochemical features of plant roots associated with ion hyperaccumulation, invasion, and tolerance of oligotrophic conditions.

The Full-Size ABCG Transporter of Medicago truncatula Is Involved in Strigolactone Secretion, Affecting Arbuscular Mycorrhiza

Frontiers in Plant Science, 2020
Strigolactones (SLs) are plant-derived signaling molecules that stimulate the hyphal branching of arbuscular mycorrhizal fungi (AMF), and consequently promote symbiotic interaction between the fungus and the plant.
