Frequent, phylogenetically local horizontal transfer of the cox1 group I intron in flowering plant mitochondria
(Oxford University Press, 2008-06)
Horizontal gene transfer is surprisingly common among plant mitochondrial genomes. The ﬁrst well-established case involves a homing group I intron in the mitochondrial cox1 gene shown to have been frequently acquired via ...
Multiple recent horizontal transfers of the cox1 intron in Solanaceae and extended co-conversion of flanking exons
(BioMed Central, 2011-09)
Background: The most frequent case of horizontal transfer in plants involves a group I intron in the mitochondrial gene cox1, which has been acquired via some 80 separate plant-to-plant transfer events among 833 diverse ...
Adh1 first intron polymorphisms in Argentinean populations of Ceratitis capitata
DNA size polymorphisms were utilized in a study of 24 natural populations of Ceratitis capitata Wiedemann (Diptera: Tephritidae) from Argentina. The first intron of alcohol dehydrogenase 1 gene (Adh1) was amplified using ...
First come, first served revisited: Factors affecting the same alternative splicing event have different effects on the relative rates of intron removal
(Cold Spring Harbor Laboratory Press, 2010-05)
Alternative splicing accounts for much of the complexity in higher eukaryotes. Thus, its regulation must allow for flexibility without hampering either its specificity or its fidelity. The mechanisms involved in alternative ...
Evolution and mechanism of the mitochondrial cox1 intron horizontal transfer in Angiosperms
(Canadian Society of Plant Biologists, 2017)
The most frequent case of horizontal gene transfer in angiosperms involves the group I intron in the cox1 mitochondrial gene, originally acquired from a fungal donor and followed by more than 100 subsequent inferred ...
The intron of the Arabidopsis thaliana COX5c gene is able to improve the drought tolerance conferred by the sunflower Hahb-4 transcription factor
Hahb-4 is a member of Helianthus annuus (sunflower) subfamily I of HD-Zip proteins. Transgenic Arabidopsis thaliana plants constitutively expressing this gene exhibit a strong tolerance of water stress in concert with ...
Complete plastome phylogeny and an update on cox1 intron evolution of Hyoscyameae (Solanaceae)
(Springer Heidelberg, 2021-08)
Within the family Solanaceae, the tribe Hyoscyameae comprises eight genera distributed across Eurasia. Despite a few attempts to understand the relationships within this tribe, the affiliations among most genera remain ...
Intronic RNAs constitute the major fraction of the non-coding RNA in mammalian cells
(BMCInmunovirologíaLondres, Inglaterra, 2022)
Horizontal gene transfer has impacted cox1 gene evolution in Cassytha filiformis
The gene cox1 is one of the most reported mitochondrial genes involved in horizontal gene transfer among angiosperms. However, whether different cox1 copies exist in different populations of a species and whether any other ...
Functional interconnections of Arabidopsis exon junction complex proteins and genes at multiple steps of gene expression
(Oxford University Press, 2011-10)
The exon junction complex (EJC) is deposited on mRNA after splicing and participates in several aspects of RNA metabolism, from intracellular transport to translation. In this work, the functional and molecular interactions ...
