Symbiotic induction of a MADS-box gene during development of alfalfa root nodules.

Abstract: In response to infection by Rhizobium, highly differentiated organs called nodules form on legume roots. Within these organs, the symbiotic association between the host plant and bacteria is established. A putative plant transcription factor, NMH7, has been identified in alfalfa root nodules. nmh7 contains a MADS-box DNA-binding region and shows homology to flower homeotic genes. This gene is a member of a multigene family in alfalfa and was identified on

“…For instance, Winter et al (1999) proved that the gnetophytes are more related to conifers than to flowering plants by constructing phylogenic trees based on MADS-box gene-families, and Theissen et al (2000) demonstrated that the phylogeny of MADS-box genes was strongly correlated with the origin and evolution of plant productive structures, such as ovules and flowers, by reviewing current knowledge on MADS-box genes in ferns, gymnosperms and different types of angiosperms. Finally, the MADS-box plays a role in the plant-microbial interaction at least in the nodule cells where its expression has been localized in infected alfalfa (Medicago sativa) root nodule cells (Heard and Dunn, 1995). So far, of more than two hundred plant MADS genes described only four have been described in legume species (two in Pisum sativum and two in Medicago sativa).…”

“…La inclusión de nódulos en este estudio se debe a estudios previos que indican la presencia de genes del grupo AP3 en tejido nodular de otras leguminosas como Glycine max o Medicago sativa (Heard y Dunn, 1995). Se usó la región C-terminal del cDNA de cada gen como sonda, a fin de evitar hibridación cruzada.…”

“…En el caso de las leguminosas algunos de estos genes pueden estar involucrados en el desarrollo de nódulos de raíz fijadores de nitrógeno: el gen MsNMH7 inicialmente se describió como específico de nódulos de Medicago sativa (Heard y Dunn, 1995), aunque posteriormente se comprobó su expresión en tejido floral (Zucchero et al, 2001) y GmNMH7 de Glycine max presenta una expresión tanto en flores en desarrollo como en nódulos .
