The European Commission’s regulatory proposal on new genomic techniques in plants: a focus on equivalence, complexity, and artificial intelligence

Environmental Sciences Europe
The European Commission has proposed to amend the EU GMO regulation, exempting certain genetically modified plants generated with new genomic techniques (NGTs) from risk assessment.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Identification and validation of reference genes for quantitative real-time PCR in Corydalis saxicola under various abiotic stresses

Scientific Reports
Quantitative real-time PCR (qRT-PCR) is a commonly used method for measuring gene expression, but its accuracy depends on the use of stable reference genes for data normalization.

Generation of Sesame Mutant Population by Mutagenesis and Identification of High Oleate Mutants by GC Analysis

Plants, 2023
Sesame is one of the important oilseed crops in the world. Natural genetic variation exists in the sesame germplasm collection. Mining and utilizing the genetic allele variation from the germplasm collection is an important approach for seed quality ...

Genetics and conservation biology

Comptes Rendus. Biologies, 2003
Conservation genetics encompasses genetic management of small populations, resolution of taxonomic uncertainties and management units, and the use of molecular genetic analyses in forensics and to understanding species' biology. The role of genetic factors in extinctions of wild populations has been controversial, but evidence now shows that they make ...

Conservation Genetics of the Cheetah: Genetic History and Implications for Conservation

, 2018
From allozymes in 1983 to whole genomes in 2015, genetic studies of the cheetah have been extensive. In this chapter we provide an overview of the available literature. Overall, patterns of genetic variation provided evidence of low variability and suggest this loss occurred thousands of years ago.

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

First Induced Mutant Population for Drought Tolerance in Vicia faba L.: Yield Traits and Stress Indices Across Generations and Water Regimes

Agronomy
Drought is a critical constraint for legume production in semi-arid regions, yet breeding for drought tolerance in faba bean through induced mutagenesis remains largely unexplored. To our knowledge, this is the first EMS-derived mutant population in faba

Assessing the phylogenetic relationship among varieties of Toona ciliata (Meliaceae) in sympatry with chloroplast genomes

Ecology and Evolution, 2023
Toona ciliata is an endangered species due to over‐cutting and low natural regeneration in China. Its genetic conservation is of an increasing concern. However, several varieties are recognized according to the leaf and flower traits, which complicates ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
