Structure of photosystem I

, 2001
In plants and cyanobacteria, the primary step in oxygenic photosynthesis, the light induced charge separation, is driven by two large membrane intrinsic protein complexes, the photosystems I and II.

Integrated Multi‐Omic Analyses Uncover a Regulatory Link Between Photosynthesis and Drought Tolerance in Field‐Grown Sorghum

Plant, Cell &Environment, EarlyView.
ABSTRACT Global warming and increasing water scarcity pose major challenges to agriculture, emphasising the need to translate stress‐biology insights into the development of drought‐resilient cultivars. In this study, we evaluated a panel of six diverse sorghum (Sorghum bicolour) accessions grown under field‐imposed drought conditions in central ...

Development of a fluidic sensor for the detection of herbicides using thylakoid preparations immobilised on magnetic beads to aid regenerability [PDF]

, 2008
Following the industrial revolution and advances in chemical science, the pollution of the environment with trace organic pollutants has been steadily increasing, which is of concern, due to their effect on the environmental and human health.

Removal of Photosystem I Subunit PsaE Leads to Photosynthetic Hydrogen Production in a Cyanobacterial PsaF‐HoxYH Fusion Strain

Plant, Cell &Environment, EarlyView.
ABSTRACT Photosynthetic hydrogen (photoH2) production is a promising approach for the utilisation of solar energy. Fusion of a hydrogenase (H2ase) to photosystem I (PSI) provides a direct light‐driven route for photoH2 generation. We established the lateral transmembrane subunit PsaF of PSI as a new fusion partner for the NiFe‐hydrogenase (HoxYH) in ...

Total peptide spectral counts from photosystem complex subunits.

, 2013
Spectral counts result from quadruplicate analyses on Fe-replete (blue) and Fe-limited (red) cultures. Photosystem II requires 2–3 atoms of Fe per complex, Cytochrome (Cyt) b6f complex requires 6 Fe atoms per complex, and photosystem I requires 12 Fe ...

Antioxidants Differentially Regulate Non‐Photochemical Quenching

Plant, Cell &Environment, EarlyView.
ABSTRACT Non‐photochemical quenching (NPQ) dissipates excess light energy as heat, limiting reactive oxygen species production during photosynthesis. Exogenous antioxidants are widely reported to improve plant performance under stress, yet their impacts on NPQ are inconsistent across studies, complicating mechanistic interpretation.

Volatile Organic Compounds Emitted by Fungi Have Substantial Effects on Growth and Disease Resistance in Arabidopsis thaliana

Plant, Cell &Environment, EarlyView.
ABSTRACT Volatile organic compounds (VOCs) emitted by certain fungi have previously been suggested to modulate plant development and their response to stresses. While some fungal species, such as Trichoderma harzianum, are known to produce VOCs, the production of VOCs in other phylogenetically divergent species, such as Mucor mucedo, was previously ...

Time‐series multi‐omics analysis of micronutrient stress in Sorghum bicolor reveals iron and zinc crosstalk and regulatory network conservation

Plant Biology, EarlyView.
Overlap between Fe and Zn responsive gene regulatory networks (GRNs) were found, indicative of micronutrient crosstalk, and conservation of root and leaf GRNs and genes suggests strong constraint on homeostasis networks in plants. Abstract Micronutrient stress impacts growth, biomass production, and grain yield in crops.

Biochemical characterization of Fucoxanthin Chlorophyll a/c binding proteins in the diatom Phaeodactylum tricornutum

, 2012
Diatoms contribute largely to the total primary production of the ecosphere and are key players in global biogeochemical cycles. Their chloroplasts are surrounded by four membranes owing to their secondary endosymbiotic origin.

Harnessing benzamides as plant stress inhibitors, growth promoters and in management of crop resilience—A review

Plant Biology, EarlyView.
Benzamides boost crop resilience by inhibiting poly(ADP‐ribose) polymerase (PARP) to enhance stress tolerance and, through their antimicrobial, herbicidal, and insecticidal derivatives, they offer broad protection for sustainable crop improvement. Abstract Benzamides have emerged as potent stress inhibitors and growth promoters in plant biotechnology ...
