Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

The FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

The physical and functional borders of transit peptide-like sequences in secondary endosymbionts

BMC Plant Biology, 2010
Background Plastids rely on protein supply by their host cells. In plastids surrounded by two membranes (primary plastids) targeting of these proteins is facilitated by an N-terminal targeting signal, the transit peptide.

A non-photosynthetic green alga illuminates the reductive evolution of plastid electron transport systems

BMC Biology, 2020
Background Plastid electron transport systems are essential not only for photosynthesis but also for dissipating excess reducing power and sinking excess electrons generated by various redox reactions.

Toward eradication of B-vitamin deficiencies : considerations for crop biofortification [PDF]

, 2018
'Hidden hunger' involves insufficient intake of micronutrients and is estimated to affect over two billion people on a global scale. Malnutrition of vitamins and minerals is known to cause an alarming number of casualties, even in the developed world ...

Multi‐omics analyses shed lights on the evolution and fruit development of Chinese raspberries (Rubus spp.)

Journal of Integrative Plant Biology, EarlyView.
High‐quality genomes of four wild raspberry species, analysis of their genetic relationships, identification of centromeres as markers for tracing their hybrid origins, exploration of fruit quality regulation, and discovery of a gene blocking anthocyanin transport and thus causing yellow fruits provides valuable resources for raspberry breeding ...

The induction of stromule formation by a plant DNA-virus in epidermal leaf tissues suggests a novel intra- and intercellular macromolecular trafficking route

Frontiers in Plant Science, 2012
Stromules are dynamic thin protrusions of membrane envelope from plant cell plastids. Despite considerable progress in understanding the importance of certain cytoskeleton elements and motor proteins for stromule maintenance, their function within the ...

NTRC Plays a Crucial Role in Starch Metabolism, Redox Balance, and Tomato Fruit Growth [PDF]

, 2019
NADPH-thioredoxin reductase C (NTRC) forms a separate thiol-reduction cascade in plastids, combining both NADPHthioredoxin reductase and thioredoxin activities on a single polypeptide.

Heterogeneity of iridoid biosynthesis in catmints: Molecular background in a phylogenetic context

Journal of Integrative Plant Biology, EarlyView.
Evolutionary gains and losses of key biosynthetic genes likely resulting from multiple independent evolutionary events explain why certain Nepeta (catnip) species produce both the active, cat‐attracting nepetalactones and sugar‐bound iridoids, while others make only the sugar‐bound forms, and some have lost iridoid production entirely.

Reactive oxygen species generated in chloroplasts contribute to tobacco leaf infection by the necrotrophic fungus Botrytis cinerea [PDF]

, 2017
Reactive oxygen species (ROS) play fundamental roles in plant responses to pathogen infection, including modulation of cell death processes and defense-related gene expression.

Biogenic retrograde signaling via GUN1 ensures thermotolerant chloroplast biogenesis during seedling establishment in Arabidopsis thaliana

Journal of Integrative Plant Biology, EarlyView.
Under heat stress, GENOMES UNCOUPLED1 (GUN1) is crucial for the formation of functional chloroplasts in seedlings under heat stress. Without GUN1, chloroplast development fails and seedlings fail to turn green. Therefore, GUN1 helps relay heat‐related cues to maintain chloroplast biogenesis and support thermotolerance during early growth.
