Guardians of the phloem – forisomes and beyond

, 2022
12451260The phloem is a highly specialized vascular tissue that forms a fundamentally important transport and signaling pathway in plants. It is therefore a system worth protecting.

Passion Fruit Cultivation: An Approach to Internal Leaf Anatomy

International Journal of Plant Biology
Some species of the genus Passiflora have leaf morphological adaptations that grow to influence the development of the plant in producing areas. Hence, the objective of this work is to quantify and characterize the leaf anatomy of passion fruit species ...

Liebig Review: Essential and Beneficial Elements in the Regulation of Cadmium Uptake and Tolerance in Crop Plants

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Cadmium (Cd2+) contamination in agricultural soils has been reported to pose risks to crop productivity, food safety, and human health. This review synthesizes current knowledge on the mechanisms by which essential (S, Zn, Fe, Mg, K, Ca) and beneficial (Si, Se, rare earth elements) elements mitigate Cd2+ toxicity in plants.

Influence of increased zinc levels on phloem transport in wheat shoots

, 1997
Elevated zinc levels may cause various symptoms in plants by interfering with ion uptake in the roots, transport processes within the plant or metabolic activities. It has been reported previously that the symplastic transport via the phloem is inhibited

Ethylene and Phloem Signals Are Involved in the Regulation of Responses to Fe and P Deficiencies in Roots of Strategy I Plants

Frontiers in Plant Science, 2019
Iron (Fe) and phosphorus (P) are two essential mineral nutrients whose acquisition by plants presents important environmental and economic implications. Both elements are abundant in most soils but scarcely available to plants.

Canola Fiber as Reinforcement for Composites: Effect of Fiber Extraction and Processing Method on Fiber Properties, Nonwoven Manufacturing, and Composite Properties

Polymer Composites, EarlyView.
Comparison of canola fiber reinforced composites manufactured using water‐retted, field‐retted, and enzyme‐treated fibers. ABSTRACT Canola fibers obtained from discarded stalks through various processing methods, including water‐retting and field‐retting followed by mechanical decortication and enzymatic degradation, were utilized as discontinuous ...

Transfer of zinc from xylem to phloem in the peduncle of wheat

, 1994
Maturing wheat grains represent major sinks for solutes in the phloem, while the xylem sap entering the ear is mainly delivered td the glumes. Nutrients and assimilates transported in the phloem may either be exported from source organs or loaded into ...

Effect of Thermospermine on the Growth and Expression of Polyamine-Related Genes in Rice Seedlings

Plants, 2019
A mutant defective in the biosynthesis of thermospermine, acaulis5 (acl5), shows a dwarf phenotype with excess xylem vessels in Arabidopsis thaliana. Exogenous supply of thermospermine remarkably represses xylem differentiation in the root of seedlings ...
