Phytochemistry, Chemotypic Diversity and Antimicrobial Potential of Essential Oils From Native Aromatic Plants of the Americas: A Systematic Review

open access: yesFlavour and Fragrance Journal, EarlyView.
This review bridges ancestral indigenous knowledge with modern pharmacology, summarizing the phytochemistry and antimicrobial properties of essential oils from seven native American species. It highlights their significant activity against bacterial, fungal and parasitic pathogens, emphasizing their potential as sustainable therapeutic and agricultural

On the nature of thiamine triphosphate in Arabidopsis

open access: yesPlant Direct, 2020
Vitamin B1 is a family of molecules, the most renowned member of which is diphosphorylated thiamine (TDP)—a coenzyme vital for the activity of key enzymes of energy metabolism.

Fungus propagules in plastids: the mycosome hypothesis [PDF]

open access: yes, 2010
A stress-induced “mycosome”phase of Aureobasidium pullulans consisting of minute reproductive propagules that may revert directly to walled yeast cells is described.

Subcellular Localization of Iron in Rhizophora mangle Leaves Revealed by Integrated Perls Reaction, TEM, STEM‐HAADF, and EDS Analyses

open access: yesMicroscopy Research and Technique, EarlyView.
Perls–TEM–STEM‐HAADF–EDS enables high‐resolution localization and elemental characterization of Fe‐containing deposits in Rhizophora mangle leaf cells. ABSTRACT Mangrove ecosystems are frequently exposed to high concentrations of iron (Fe) in sediments, resulting in Fe accumulation in plant tissues. Although Fe is an essential micronutrient involved in

The Main Functions of Plastids.

open access: yes, 2018
International audiencePlastids are semiautonomous organelles like mitochondria, and derive from a cyanobacterial ancestor that was engulfed by a host cell. During evolution, they have recruited proteins originating from the nuclear genome, and only parts

Intra‐Plant Nitrogen Isotope Fractionation in Maize

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background and aim The natural abundance of nitrogen isotopes (δ15N) provides a powerful integrative tracer of nitrogen uptake and assimilation in plants, yet the internal partitioning of δ15N among plant tissues remains insufficiently understood.

The activity of NADH-, NADPH- and Fd-dependent glutamate synthase in the plastids and cytosol of Pisum arvense L. root cells

open access: yesActa Societatis Botanicorum Poloniae, 2014
Three forms of glutamate synthase (NADH-GOGAT, NADPH-GOGAT and Fd-(ferredoxin) GOGAT) were found in the plastids and cytosol of Pisum arvense root cells.

Silicon differentially protects PSII and PSI photochemistry and preserves fatty acid metabolism in salt‐stressed Sorghum bicolor (L.)

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Silicon (Si) has been demonstrated to be an important element to enhance crop tolerance against salinity. Nevertheless, mechanisms underlying Si's mitigation of salt stress remains insufficiently explored and understood. This study aims to provide new insights into Si's impact on salt‐stressed Sorghum bicolor (L.) supplied or not ...

Nectar defense and hydrogen peroxide in floral nectar of Cucurbita pepo

open access: yesActa Agrobotanica, 2015
This study was carried out to investigate some similarities between the nectaries of Nicotiana sp. and Cucurbita pepo, such as starch accumulation in the nectary parenchyma, changes in nectary color during maturation, and the production of a large ...

Rethinking plastid evolution [PDF]

open access: yesThe EMBO Reports, 2010
How easy is it to acquire an organelle? How easy is it to lose one? These questions underpin the current debate about the evolution of the plastid—that is, chloroplast—the organelle of photosynthesis in eukaryotic cells. The origin of the plastid has been traced to an endosymbiosis between a eukaryotic host cell and a cyanobacterial symbiont, the ...
