Auxin: at the root of nodule development?

Abstract: Abstract. Root nodules are formed as a result of an orchestrated exchange of chemical signals between symbiotic nitrogen fixing bacteria and certain plants. In plants that form nodules in symbiosis with actinorhizal bacteria, nodules are derived from lateral roots. In most legumes, nodules are formed de novo from pericycle and cortical cells that are re-stimulated for division and differentiation by rhizobia. The ability of plants to nodulate has only evolved recently and it has, therefore, been suggested that… Show more

“…Auxin transport inhibition appears to be specific for indeterminate nodulation, possibly reflecting the different requirements for cell division in either inner or outer cortical cells in the two types of nodules (Mathesius, 2008). These data clearly indicate the importance of flavonoids in the regulation of auxin transport during nodulation.…”

“…24,29 In contrast, auxin transport in indeterminate nodulators is transiently blocked just above the site of nodule initiation, while cytokinin appears to promote cell divisions and activate the nodule developmental program in the inner cortex. 28,32 The role of ABA during lateral root and nodule development is more complex. In lateral roots, ABA appears to function later than auxin and cytokinin, regulating meristem activity during emergence from the primary root, but the effect of exogenous ABA is opposite in legumes and non-legumes: promoting lateral root elongation in legumes, but inhibiting it in non-legumes.…”

“…Auxin is a crucial regulator of lateral root (Fukaki et al, 2007) and nodule (Mathesius, 2008) development. Lateral root initiation is dependent on auxin transport from the root tip to the lateral root initiation zone (Reed et al, 1998;Casimiro et al, 2001), whereas auxin transport from the shoot to the root is required for lateral root elongation (Bhalerao et al, 2002).…”
