Distribution of genetic variability in mature and progeny populations of Abies alba Mill. from the Polish Western and Eastern Carpathians

open access: yesJournal of Forest Science, 2023
This study aimed to compare patterns in the genetic structure of 27 mature stands and the natural regeneration of A. alba in the Eastern and Western Carpathians within the introgression zone of two refugial lineages from the Apennine and Balkan ...

Turnover-synthesis of chloroplast DNA in developing chloroplasts [PDF]

open access: yesJournal of Bacteriology, 1978
The mechanism for the turnover-synthesis of chloroplast DNA in the absence of net synthesis during the chloroplast maturation in Euglena gracilis was determined. DNA synthesis was measured by incorporation of32Pi into chloroplast DNA. The density label, 15N, was incorporated to examine the mechanism of turnover-synthesis. The newly synthesized segments

The relative copy number of mitochondrial and chloroplast DNA in young and mature leaves of different grape varieties [PDF]

open access: yesBIO Web of Conferences, 2023
The copy number of DNA matrices of subcellular organelles (plants) can serve as an indicator of the intensity of photosynthesis and oxidative phosphorylation processes.

Chloroplast and mitochondrial DNA editing in plants [PDF]

open access: yesNature Plants, 2021
Abstract Plant organelles, including mitochondria and chloroplasts, contain their own genomes, which encode hundreds of genes essential for respiration and photosynthesis, respectively. Gene editing in plant organelles, an unmet need for plant genetics and biotechnology, has been hampered by the lack of appropriate tools for targeting DNA in ...

Different fates of the chloroplast tufA gene following its transfer to the nucleus in green algae [PDF]

open access: yes, 1990
Previous work suggested that the tufA gene, encoding protein synthesis elongation factor Tu, was transferred from the chloroplast to the nucleus within the green algal lineage giving rise to land plants.

Comparative analysis of the complete plastomes of nine Pimpinella species (Apiaceae) from China [PDF]

open access: yesPeerJ, 2023
Pimpinella L. is one of the large genera in the Apiaceae family. In a previous study, the molecular phylogenies of Pimpinella were explored using nuclear ribosomal DNA internal transcribed spacers (ITS) and several chloroplast DNA segments.

Oryza sativa ObgC1 Acts as a Key Regulator of DNA Replication and Ribosome Biogenesis in Chloroplast Nucleoids

open access: yesRice, 2021
Background The Spo0B-associated GTP-binding protein (Obg) GTPase, has diverse and important functions in bacteria, including morphological development, DNA replication and ribosome maturation. Homologs of the Bacillus subtilis Obg have been also found in

Chloroplast genome sequencing analysis of Heterosigma akashiwo CCMP452 (West Atlantic) and NIES293 (West Pacific) strains

open access: yesBMC Genomics, 2008
Background Heterokont algae form a monophyletic group within the stramenopile branch of the tree of life. These organisms display wide morphological diversity, ranging from minute unicells to massive, bladed forms.
