1 maj 2013 · What are the evolutionary origins of plant-specific TFs? What do the conserved motifs signify? How do the DBDs recognize specific DNA sequences? Three-dimensional structures provide clues to answer these questions.
We investigate the different interactions that add to the stable structure of B-DNA: that is hydrogen-bonding, π–π stacking interactions, cross-terms (interaction between X and Y′, see Scheme 3) and the influence of these two interactions onto each other.
22 wrz 2014 · These agents cause variety of DNA damages including DNA base oxidation and alkylation, formation of pyrimidine dimers and abasic sites, single and double strand breaks (SSBs and DSBs), DNA inter-strand cross links and therefore seriously threat the integrity of plant genome.
22 lis 2004 · 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 cells have been elucidated. DSBs are mainly repaired by non-homologous end-joining (NHEJ).
11 paź 2011 · DNA double-strand break (DSB) repair mechanisms are important for genome stability, fertility and genetic diversity and also mediate the integration of transgenes into the plant genome. Recombination pathways are therefore of interest to biotechnologists as important targets for crop improvement.
31 sie 2005 · Plants, which with algae are the only photosynthetic eukaryotes, have evolved very effective pathways for DNA damage signalling and repair, and this review summarises our current understanding of these processes in the responses of plants to genotoxic stress.
21 cze 2021 · The plant DNA damage response is evolving as a key process influencing plant growth and development in response to adverse environmental cues. The DNA damage response directly influences genome stability by preventing the accumulation of mutations within the organism.
