additional information | knockdown of PvIFR1 mediated by RNA interference (RNAi) in common bean composite plants results in a reduction of shoot and root length. Reduction of PvIFR1 mRNAs also affects growth of lateral roots after emergence, a stage in which auxins are required to establish a persistent meristem. IFR RNAi affects the number of nodules | Phaseolus vulgaris |

malfunction | knockdown of PvIFR1 mediated by RNA interference (RNAi) in common bean composite plants results in a reduction of shoot and root length. Reduction of PvIFR1 mRNAs also affects growth of lateral roots after emergence, a stage in which auxins are required to establish a persistent meristem. Upon inoculation, the number of nodules formed by different strains of Rhizobium etli is significantly lower in IFR RNAi than in control roots. Transcript levels of two auxin-regulated genes are consistent with lower levels of auxin in PvIFR1 silenced roots. No differences in mRNA levels of PvIFR1 are observed between shoots of IFR and GUS RNAi composite plants, indicating that the shoot phenotype is not caused by systemic silencing of PvIFR1.
