Summary UV ‐B radiation inhibits plant growth, and this inhibition is, to a certain extent, regulated by miR396‐mediated repression of Growth Regulating Transcription factors ( GRF s). Moreover, E2Fe transcription factor also modulates Arabidopsis leaf growth. Here, we provide evidence that, at intensities that induce DNA damage, E2Fc participates in the cell proliferation. We demonstrate ‐deficient plants show lower size under conditions damage , decreased death after exposure altered SOG 1...
In Arabidopsis thaliana plants, exposure to UV-B induces an inhibition of primary root elongation. Different mutants have been isolated that are deficient in this response; however, little is known about the cellular and molecular mechanisms regulate elongation seedlings exposed UV-B. work, we investigated effect irradiation different organs on Our results demonstrate leaves shoots only induce a partial elongation, while when roots radiation, similar as measured complete seedling irradiated....
SUMMARY Ultraviolet (UV)B radiation affects plant growth inhibiting cell proliferation. This inhibition is in part controlled by the activity of transcription factors from E2F family. In particular, participation E2Fc and E2Fe UV‐B responses Arabidopsis plants was previously reported. However, E2Fa E2Fb contribution to these processes has still not been investigated. Thus, this work, we provide evidence that, Arabidopsis, both control leaf size under conditions without participating repair...
