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

Maintenance of genome integrity is a key issue for all living organisms. Cells are constantly
exposed to DNA damage due to replication or transcription, cellular metabolic activities …

Eukaryotes have evolved complex mechanisms to repair DNA double-strand breaks (DSBs)
through coordinated actions of protein sensors, transducers, and effectors. Here we show …

UV-B radiation is a key environmental signal that initiates diverse responses in plants that
affect metabolism, development, and viability. Many effects of UV-B involve the differential …

Because the genome stores all genetic information required for growth and development, it
is of pivotal importance to maintain DNA integrity, especially during cell division, when the …

Being sessile organisms, plants are ubiquitously exposed to stresses that can affect the DNA
replication process or cause DNA damage. To cope with these problems, plants utilize DNA …

Plants are photosynthetic organisms that depend on sunlight for energy. Plants respond to
light through different photoreceptors and show photomorphogenic development. Apart from …

The reversible phosphorylation of proteins on serine, threonine, and tyrosine residues is an
important biological regulatory mechanism. In the context of genome integrity, signaling …

Genome integrity is continuously threatened by external stresses and endogenous hazards
such as DNA replication errors and reactive oxygen species. The DNA damage checkpoint …

Plant growth and development are driven by the continuous generation of new cells.
Whereas much has been learned at a molecular level about the mechanisms that …
