Resumen:
Plants are extremely plastic organisms with the ability to adapt and respond to the changing environmentalconditions surrounding them. Sunlight is one of the main resources for plants, both as a primary energy sourcefor photosynthesis and as a stimulus that regulates different aspects of their growth and development. UV-Bcomprises wavelengths that correspond to a high energy region of the solar spectrum capable of reaching thebiosphere, influencing plant growth. It is currently believed that plants are able to acclimate when growingunder the influence of this radiation and perceive it as a signal, without stress signs. Nonetheless, many UV-Binduced changes are elicited after DNA damage occurs as a consequence of exposure. In this review we focus onthe influence of UV-B on leaf, flower and root development and emphasize the limited understanding of themolecular mechanisms for most of this developmental processes affected by UV-B documented over the years ofresearch in this area.
