Highlights•CRISPR/Cas mediated gene editing is becoming routine for plants.•Much more
can be achieved in future by further applications.•Gene editing will become more precise …

Transposable elements (TEs) are the key players in generating genomic novelty by a
combination of the chromosome rearrangements they cause and the genes that come under …

The CRISPR/C as nuclease is becoming a major tool for targeted mutagenesis in
eukaryotes by inducing double‐strand breaks (DSB s) at pre‐selected genomic sites that are …

The genomic integrity of every organism is constantly challenged by endogenous and
exogenous DNA-damaging factors. Mutagenic agents cause reduced stability of plant …

The natural transfer of DNA from mitochondria to the nucleus generates nuclear copies of
mitochondrial DNA (numts) and is an ongoing evolutionary process, as genome sequences …

The efficient repair of double-strand breaks (DSBs) in genomic DNA is important for the
survival of all organisms. In recent years, basic mechanisms of DSB repair in somatic plant …

It has been argued that the evolution of plant genome size is principally unidirectional and
increasing owing to the varied action of whole-genome duplications (WGDs) and mobile …

Enormous strides have been made in the study of polyploidy over the last 20 yr. Here, we
highlight some of these discoveries and note where our understanding of polyploid …

Key message We summarize recent progress of CRISPR/Cas9-mediated gene targeting in
plants, provide recommendations for designing gene-targeting vectors and highlight the …

Genome size varies greatly across angiosperms. It is well documented that, in addition to
polyploidization, retrotransposon amplification has been a major cause of genome …
