Upper Rhine Valley: A migration crossroads of middle European oaks [PDF]
Forest Ecology and Management 304 (2013): pp. 89-98, 2013 The indigenous oak species (Quercus spp.) of the Upper Rhine Valley have migrated to their current distribution range in the area after the transition to the Holocene interglacial. Since post-glacial recolonization, they have been subjected to ecological changes and human impact. By using chloroplast microsatellite markers (cpSSRs), we provide detailed

Proceedings of the National Academy of Sciences of the United States of America, 2015 Chloroplasts and mitochondria are subcellular bioenergetic organelles with their own genomes and genetic systems. DNA replication and transmission to daughter organelles produces cytoplasmic inheritance of characters associated with primary events in ...

Electronic Nanomaterials for Plants: A Review on Current Advances and Future Prospects
Advanced Electronic Materials, EarlyView.Global food security faces mounting challenges from climate change and rapid population growth. This review highlights the pivotal role of electronic nanomaterials–including metals, metal oxides, and carbon‐based structures–in enhancing plant photosynthesis, nutrient uptake, and stress resilience. Furthermore, it explores how emerging platforms such as

How a simple chloroplast psbA gene mutation changed world agriculture [PDF]
arXiv, 2023 Atrazine as a weed control tactic profoundly changed world agriculture. Long-term use revealed resistant biotypes, R, with a single base pair mutation of the chloroplast psbA gene. The R phenotype emerged from a sequential cascade of pleiotropic effects from the plastid to the whole plant.

Salinity Response in Chloroplasts: Insights from Gene Characterization
International Journal of Molecular Sciences, 2017 Salinity is a severe abiotic stress limiting agricultural yield and productivity. Plants have evolved various strategies to cope with salt stress. Chloroplasts are important photosynthesis organelles, which are sensitive to salinity.

Genome hybridization: A universal way for the origin and diversification of organelles as well as the origin and speciation of eukaryotes [PDF]
arXiv, 2023 The origin of organelles (mitochondrion, chloroplast and nucleus) remains enigmatic. The endosymbiotic hypothesis that chloroplasts, mitochondria and nuclei descend from the endosymbiotic cyanobacterium, bacterium and archaebacterium respectively is dominant yet uncompelling, while our discovery of de novo organelle biogenesis in the cyanobacterium ...

Ubiquitin facilitates a quality-control pathway that removes damaged chloroplasts
Science, 2015 Quality control one chloroplast at a time How do plant cells get rid of chloroplasts that are not working as they should? Woodson et al. describe a chloroplast quality-control pathway that allows for the selective elimination of individual chloroplasts ...

Genome‐wide identification and biological relevance of broccoli aquaporins
The Plant Genome, Volume 15, Issue 4, December 2022., 2022 Abstract Broccoli (Brassica oleracea var. italica) is an important crop worldwide, and its regular consumption is associated with health benefits due to the presence of various bioactive compounds. An optimal water balance and homeostasis are needed for plant growth; in this sense, aquaporins play a crucial role.
