Regulatory Shifts in Plastid Transcription Play a Key Role in Morphological Conversions of Plastids during Plant Development

Frontiers in Plant Science, 2017
Plastids display a high morphological and functional diversity. Starting from an undifferentiated small proplastid, these plant cell organelles can develop into four major forms: etioplasts in the dark, chloroplasts in green tissues, chromoplasts in ...

Comprehensive Expression Analyses of Plastidial Thioredoxins of Arabidopsis thaliana Indicate a Main Role of Thioredoxin m2 in Roots

Antioxidants, 2022
Thioredoxins (TRXs) f and m are redox proteins that regulate key chloroplast processes. The existence of several isoforms of TRXs f and m indicates that these redox players have followed a specialization process throughout evolution.

Evolution of plastid genomes of Holcoglossum (Orchidaceae) with recent radiation

BMC Evolutionary Biology, 2019
The plastid is a semiautonomous organelle with its own genome. Plastid genomes have been widely used as models for studying phylogeny, speciation and adaptive evolution.

Allelic Variation in Maize Malate Dehydrogenase 7 Shapes Promoter Methylation and Banded Leaf and Sheath Blight Resistance

Advanced Science, EarlyView.
In this study maize chloroplastic malate dehydrogenase7 (ZmMDH7), is identified as a Rhizoctonia solani resistance gene in maize. ZmMDH7 is regulated by transcription factor ZmWRKY44 via pathogens challenge to elevate mitochondrial ROS and SA signaling pathway.

Autophagy regulates plastid reorganization during spermatogenesis in the liverwort Marchantia polymorpha

Frontiers in Plant Science, 2023
Autophagy is a highly conserved system that delivers cytoplasmic components to lysosomes/vacuoles. Plastids are also degraded through autophagy for nutrient recycling and quality control; however, the involvement of autophagic degradation of plastids in ...

The chloroplast genome sequence of bittersweet (Solanum dulcamara): Plastid genome structure evolution in Solanaceae

PLoS ONE, 2018
Bittersweet (Solanum dulcamara) is a native Old World member of the nightshade family. This European diploid species can be found from marshlands to high mountainous regions and it is a common weed that serves as an alternative host and source of ...

Chloroplast Stress Signals Orchestrate Epidermis‐Specific Remodeling of Mitochondria and ER Under High Light

Advanced Science, EarlyView.
High light exposure triggers an epidermis‐specific remodeling of mitochondria and ER in Arabidopsis, driven by chloroplast‐derived signals. Live‐cell imaging shows that HL rapidly suppresses mitochondrial motility, followed by fusion‐driven elongation and ER cisternal expansion.

CCS2, an Octatricopeptide-Repeat Protein, Is Required for Plastid Cytochrome c Assembly in the Green Alga Chlamydomonas reinhardtii

Frontiers in Plant Science, 2017
In bacteria and energy generating organelles, c-type cytochromes are a class of universal electron carriers with a heme cofactor covalently linked via one or two thioether bonds to a heme binding site. The covalent attachment of heme to apocytochromes is

Novel genetic code and record-setting AT-richness in the highly reduced plastid genome of the holoparasitic plant Balanophora

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Many groups of flowering plants have become parasites and have lost the capacity to carry out photosynthesis. The plastid genomes of these parasitic plants are often highly reduced in size and gene content and are divergent in other ways too.

Phylogenomics, ecomorphological evolution, and historical biogeography in Deuterocohnia (Bromeliaceae: Pitcairnioideae)

American Journal of Botany, EarlyView.
Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.
