  abstract = {{C}rotalaria are plants of the {F}abaceae family whose nodulation characteristics have been little explored despite the recent discovery of their unexpected ability to be efficiently nodulated in symbiosis with bacteria of the genus {M}ethylobacterium. {I}t has been shown that methylotrophy plays a key role in this unusual symbiotic system, as it is expressed within the nodule and as non-methylotroph mutants had a depleting effect on plant growth response. {W}ithin the nodule, {M}ethylobacterium is thus able to obtain carbon both from host plant photosynthesis and from methylotrophy. {I}n this context, the aim of the present study was to show the histological and cytological impacts of both symbiotic and methylotrophic metabolism within {C}rotalaria podocarpa nodules. {I}t was established that if {C}rotalaria nodules are multilobed, each lobe has the morphology of indeterminate nodules but with a different anatomy; that is, without root hair infection or infection threads. {I}n the fixation zone, bacteroids display a spherical shape and there is no uninfected cell. {C}rotalaria nodulation by {M}ethylobacterium displayed some very unusual characteristics such as starch storage within bacteroid-filled cells of the fixation zone and also the complete lysis of apical nodular tissues (where bacteria have a free-living shape and express methylotrophy). {T}his lysis could possibly reflect the bacterial degradation of plant wall pectins through bacterial pectin methyl esterases, thus producing methanol as a substrate, allowing bacterial multiplication before release from the nodule.},
