lncRNA–DNA hybrids regulate distant genes

EMBO reports, 2020
lncRNAs actively regulate gene expression. They contribute to chromosomal interactions at close or distant genomic regions, which, in turn, regulate transcription [1]. Ariel et al [2] reveal in a recent study a new molecular mechanism of the Arabidopsis lncRNA APOLO.

Exogenous paternal mitochondria rescue hybrid incompatibility and the destiny of exogenous mitochondria

Reproduction and Breeding, 2022
The mitochondria of most organisms follow strict maternal inheritance, and the mechanism of elimination of paternal mitochondria is unclear. Our previous studies showed that the paternal mtDNA presented in the embryo of hybrid Megalobrama Amblycephala ...

Comparative chromosome painting discloses homologous Segments in distantly related mammals [PDF]

, 1994
Comparative chromosome painting, termed ZOO-FISH, using DNA libraries from flow sorted human chromosomes 1,16,17 and X, and mouse chromosome 11 discloses the presence of syntenic groups in distantly related mammalian Orders ranging from primates (Homo

Hybrid attention-based transformer block model for distant supervision relation extraction [PDF]

Neurocomputing, 2022
With an exponential explosive growth of various digital text information, it is challenging to efficiently obtain specific knowledge from massive unstructured text information. As one basic task for natural language processing (NLP), relation extraction aims to extract the semantic relation between entity pairs based on the given text.

Evidence of distant hybridization within Central Asian feather grasses (Poaceae: Stipa)

Turczaninowia, 2022
The genus Stipa is one of the largest genera of Poaceae. The phylogeny of the genus is still poorly resolved, and one of the main problems is linked to the extensive inter and intrasectional hybridization.
