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

open access: yesJournal 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 ...

Sustained diurnal stimulation of cyclic electron flow in two tropical tree species Erythrophleum guineense and Khaya ivorensis

open access: yesFrontiers in Plant Science, 2016
The photosystem II (PSII) activity of C3 plants is usually inhibited at noon associated with high light but can be repaired fast in the afternoon. However, the diurnal variation of photosystem I (PSI) activity is unknown.

Ferredoxin and flavodoxin reduction by photosystem I

open access: yes, 2001
Ferredoxin and flavodoxin are soluble proteins which are reduced by the terminal electron acceptors of photosystem I. The kinetics of ferredoxin (flavodoxin) photoreduction are discussed in detail, together with the last steps of intramolecular ...

Effect of saline irrigation on Tetragonia tetragonioides (Pall.) Kuntze grown on different soil types under greenhouse conditions

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change and population growth are major challenges for sustainable food production, particularly in regions affected by water scarcity and soil salinization. In this context, halophytes represent promising candidates as alternative and sustainable food crops for salt‐affected areas.

A demonstration of energy transfer from photosystem II to photosystem I in chloroplasts

open access: yes, 1976
Photosystem I activity of Tris-washed chloroplasts was measured at room temperature as the rate of photoreduction of NADP and as the rate of oxygen uptake mediated by methyl viologen in both cases using dichlorophenolindophenol plus ascorbate as the ...

Physiological dominance of the scion in shaping root architecture under suboptimal temperature

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Non‐optimal temperatures have become a major constraint on plant development under rapidly changing climatic conditions. Both suboptimal and supra‐optimal temperatures reduce physiological activity, alter plant morphology, lead to plant mortality, and ultimately decrease crop productivity.

Structural and functional characterisation of Photosystem II from two His-tagged transplastomic strains of Nicotiana tabacum

open access: yes, 2009
Photosystem II (PSII) is a polypeptide-cofactor complex organised as a homodimeric multisubunit protein embedded in the thylakoid membrane. PSII monomers are heterooligomers related to each other by a pseudo-twofold axis perpendicular to the membrane ...

Apple scar skin viroid causes dapple and scar skin apple diseases by disrupting phenylpropanoid‐mediated metabolic pathways

open access: yesNew Plant Protection, EarlyView.
Dapple apple and scar skin apple diseases are closely associated with suppression of anthocyanin biosynthesis and enhancement of suberin biosynthesis. Apple scar skin viroid (ASSVd) infection represses anthocyanin biosynthesis in apple callus. Abstract Apple scar skin viroid (ASSVd) causes dapple and scar skin apple diseases, posing serious threats to ...

Integrating tunable LED‐induced plant responses with novel solar cell technologies for energy‐efficient agrivoltaic systems

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The increasing demand for sustainable food production requires innovative solutions that balance productivity, resource efficiency, and environmental impact. Vertical Farming Systems (VFSs) offer a promising approach; however, their high energy consumption remains challenging.
