Can DNA from wet, temperate soils be used for palaeoecological reconstruction?

Journal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary ancient DNA in well‐dated contexts (sedaDNA) has great potential as a palaeoecological proxy. A few studies have attempted palaeoecological reconstructions using sedaDNA from soil; these studies have been mainly restricted to cold and/or dry soils.

Chloroplast RNA polymerases: Role in chloroplast biogenesis

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2015
Plastid genes are transcribed by two types of RNA polymerase in angiosperms: the bacterial type plastid-encoded RNA polymerase (PEP) and one (RPOTp in monocots) or two (RPOTp and RPOTmp in dicots) nuclear-encoded RNA polymerase(s) (NEP). PEP is a bacterial-type multisubunit enzyme composed of core subunits (coded for by the plastid rpoA, rpoB, rpoC1 ...

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Expression of a Chloroplast-Targeted Cyanobacterial Flavodoxin in Tomato Plants Increases Harvest Index by Altering Plant Size and Productivity

Frontiers in Plant Science, 2019
Tomato is the most important horticultural crop worldwide. Domestication has led to the selection of highly fruited genotypes, and the harvest index (HI), defined as the ratio of fruit yield over total plant biomass, is usually employed as a biomarker of

Integrated phytochemical and bioactivity profiling of Xanthium strumarium fruits from Korea and China: Implications for origin‐specific quality specification

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Geographic origin influences the phytochemical composition and biological activities of medicinal plant resources. Xanthium strumarium L. (XS) fruit is widely used in East Asian traditional medicine. However, current pharmacopeial standards primarily recognize Chinese‐derived material, despite the availability and traditional use of

Preharvest supplemental lighting enhances productivity and modulates postharvest quality in hydroponically grown Apulian unripe melon ‘Scopatizzo’ (Cucumis melo L.)

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Preharvest light management is increasingly used to enhance yield and fruit quality in soilless systems, yet its effects on unripe melon fruits remain poorly understood. This study evaluated the impact of supplemental red–blue light‐emitting diode (LED) lighting applied during cultivation in a closed‐cycle hydroponic system on ...

Assessing plant water status: Part 1 – Classical methods

Journal of the Science of Food and Agriculture, EarlyView.
Abstract As a result of the changing climate, water scarcity poses a significant threat to crop and pasture production. Although soil water content can indicate drought, its measurements often provide limited spatial resolution and are weakly correlated with plant water status, producing misleading drought assessments.

Recent Advances (2023–2025) of Capillary Electrophoresis‐Mass Spectrometry (CE‐MS) for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Top‐down proteomics (TDP) characterizes proteoforms in cells, tissues, and biofluids, in discovery mode and on a global scale, requiring analytical tools with high peak capacity for proteoform separation and high sensitivity for proteoform detection, given the extremely high proteoform complexity and wide proteoform concentration dynamic range.

Ultrastructural Characteristics and Viral Replication Sites in Chloroplasts of Kimchi Cabbage Cells infected with Turnip Yellow Mosaic Virus [PDF]

Research in Plant Disease
A significant number of vesicles developed at the inner edge of chloroplasts of kimchi cabbage cells infected with turnip yellow mosaic virus (TYMV). The vesicle found in the chloroplasts are typical ultrastructures resulting from infection of TYMV.

Beyond Bioenergetics: Moonlighting Functions of F1FO‐ATPase From ATP Synthesis to an ATP‐Wasting Death Switch

Medicinal Research Reviews, EarlyView.
ABSTRACT Mitochondrial F1FO‐ATPase is classically viewed as the “splendid” rotary nanomachine that sustains life by converting the proton‐motive force (pmf) into ATP. Yet this same complex can adopt a second, context‐dependent function that links bioenergetics to cell fate.
