Cation diffusion facilitator proteins of Beta vulgaris reveal diversity of metal handling in dicotyledons.

Manganese (Mn), iron (Fe), and zinc (Zn) are essential for diverse processes in plants, but their availability is often limiting or excessive. Cation diffusion facilitator (CDF) proteins have been implicated in the allocation of those metals in plants, whereby most of our mechanistic understanding has been obtained in Arabidopsis. It is unclear to what extent this can be generalized to other dicots.

AtDTX25, a member of the multidrug and toxic compound extrusion family, is a vacuolar ascorbate transporter that controls intracellular iron cycling in Arabidopsis.

Iron (Fe) is an essential element, its transport is regulated by the cell redox balance. In seeds, Fe enters the embryo as Fe and is stored in vacuoles as Fe . Through its ferric reduction activity, ascorbate plays a major role in Fe redox state and therefore Fe transport within the seed.

Developing a Sufficient Protocol for the Enhancement of α-Glucosidase Inhibitory Activity by L. Aeroponic Hairy Roots Using Exogenous Factors, a Precursor, and an Elicitor.

Aeroponics is considered as a potential method for the culture of herbal plants due to the high growth rate, quantity and quality enhancement of secondary metabolites, and substantial environmental progress associated with this method. The aim of this study was to develop a sufficient protocol for successful hairy root induction by ATCC 15834, using a precursor and elicitor to enhance α-glucosidase inhibitory activity (GIA) of aeroponic hairy roots (AHRs) in greenhouse conditions. In this study, we found that the optimized procedure (10 min, Woody plant medium (WPM), 1/25 salt strength) had an outstanding effect with a reduction in the rooting time (RT), promotion of the rooting rate (RR), and increase in the fresh weight (FW) and dry weight (DW) compared with the original procedure (30 min, Murashige and Skoog (MS) medium, 1/25 salt strength) after 30 days of culture.

PS01 Isolated from Maize Rhizosphere Alters Root System Architecture and Promotes Plant Growth.

The objectives of this study were to evaluate the plant growth promoting effects on by sp. strains associated with rhizosphere of crop plants grown in Mekong Delta, Vietnam. Out of all the screened isolates, PS01 isolated from maize rhizosphere showed the most prominent plant growth promoting effects on and maize ( ).

Plant growth-promoting rhizobacterium Pseudomonas PS01 induces salt tolerance in Arabidopsis thaliana.

Objectives: Plant growth-promoting rhizobacteria (PGPR) may contribute to sustainable crop production by improving plant growth and/or plant tolerance to abiotic stresses. Soil salinity, which limits the productivity of crop plants, is one of the major concerns of modern agriculture, especially in countries heavily affected by climate change as Vietnam. Currently, only a few reports have studied local PGPR isolated in Vietnam, particular Pseudomonas.

Chloroplast-localized BICAT proteins shape stromal calcium signals and are required for efficient photosynthesis.

The photosynthetic machinery of plants must be regulated to maximize the efficiency of light reactions and CO fixation. Changes in free Ca in the stroma of chloroplasts have been observed at the transition between light and darkness, and also in response to stress stimuli. Such Ca dynamics have been proposed to regulate photosynthetic capacity.

Ascorbate efflux as a new strategy for iron reduction and transport in plants.

Iron (Fe) is essential for virtually all living organisms. The identification of the chemical forms of iron (the speciation) circulating in and between cells is crucial to further understand the mechanisms of iron delivery to its final targets. Here we analyzed how iron is transported to the seeds by the chemical identification of iron complexes that are delivered to embryos, followed by the biochemical characterization of the transport of these complexes by the embryo, using the pea (Pisum sativum) as a model species.
