Resumen:
Transcription factors are DNA binding proteins that
regulate gene expression. The nitrogen fixing symbiosis
established between legume plants and soil bacteria is
a complex interaction, in which plants need to integrate
signals derived from the symbiont and the surrounding
environment to initiate the developmental program of
nodule organogenesis and the infection process. Several
transcription factors that play critical roles in these processes
have been reported in the past decade, including proteins
of the GRAS and NF-Y families. Recently, we reported the
characterization of a new GRAS domain containing-protein
that interacts with a member of the C subunit of the NF-Y
family, which plays an important role in nodule development
and the progression of bacterial infection during the
symbiotic interaction. The connection between transcription
factors of these families highlights the significance of
multimeric complexes in the fabulous capacity of plants to
integrate and respond to multiple environmental stimuli.
