title: Plant NF-Y transcription factors: Key players in plant-microbe interactions, root development and adaptation to stress.
abstract: NF-Ys are heterotrimeric transcription factors composed by the NF-YA, NF-YB and NF-YC subunits. In plants, NF-Y subunits are encoded by multigene families whose members show structural and functional diversifications. An increasing number of NF-Y genes has been shown to play key roles during different stages of root nodule and arbuscular mycorrhizal symbiosis, as well as during the interaction of plants with pathogenic microorganisms. Individual members of the NF-YA and NF-YB families have also been implicated in the development of primary and lateral roots. In addition, different members of the NF-YA and NF-YB gene families from mono- and di-cotyledonous plants have been involved in plant responses to water and nutrient scarcity. This review presents the most relevant and striking results concerning these NF-Y subunits. A phylogenetic analysis of the functionally characterized NF-Y genes revealed that, across plant species, NF-Y proteins functioning in the same biological process tend to belong to common phylogenetic groups. Finally, we discuss the forthcoming challenges of plant NF-Y research, including the detailed dissection of expression patterns, the elucidation of functional specificities as well as the characterization of the potential NF-Y-mediated epigenetic mechanisms by which they control the expression of their target genes. This article is part of a Special Issue entitled: Nuclear Factor Y in Development and Disease, edited by Prof. Roberto Mantovani.
