Abstract Arbuscular mycorrhiza (AM) is a widespread symbiosis between roots of the majority land plants and Glomeromycotina fungi. AM important for ecosystem health functioning as fungi critically support plant performance by providing essential mineral nutrients, particularly poorly accessible phosphate, in exchange organic carbon. colonize inside this promoted at low but inhibited high phosphate status, while mechanistic basis phosphate-dependence remained obscure. Here we demonstrate that...
Legume roots form two types of postembryonic organs, lateral and symbiotic nodules. Nodule formation is the result interaction legumes with rhizobia requires mitotic activation differentiation root cells as well an independent, but coordinated, program that allows infection by rhizobia. MicroRNA390 (miR390) evolutionarily conserved microRNA targets
Legume plants develop two types of root postembryonic organs, lateral roots and symbiotic nodules, using shared regulatory components. The module composed by the microRNA390, Trans-Acting SIRNA3 (TAS3) RNA Auxin Response Factors (ARF)2, ARF3, ARF4 (miR390/TAS3/ARFs) mediates control both nodules in legumes. Here, a transcriptomic approach identified member Lateral Organ Boundaries Domain (LBD) family transcription factors Medicago truncatula, designated MtLBD17/29a, which is regulated...
Auxin Response Factors (ARFs) constitute a large family of transcription factors that mediate auxin-regulated developmental programs in plants. ARF2 , ARF3 and ARF4 are post-transcriptionally regulated by the microRNA390 (miR390)/ trans -acting small interference RNA 3 ( TAS3 ) module through action -derived - acting interfering RNAs (ta-siRNA). We have previously reported constitutive activation miR390/ pathway promotes elongation lateral roots but impairs nodule organogenesis infection...
Translational control is a widespread mechanism that allows the cell to rapidly modulate gene expression in order provide flexibility and adaptability eukaryotic organisms. We applied translating ribosome affinity purification combined with RNA sequencing characterize translational regulation of mRNAs at early stages nitrogen-fixing symbiosis established between
Legumes establish endosymbioses with arbuscular mycorrhizal (AM) fungi or rhizobia bacteria to improve mineral nutrition. Symbionts are hosted in privileged habitats, root cortex (for AM fungi) nodules rhizobia) for efficient nutrient exchange.
