摘要： Understanding the reciprocal interaction between root development and coadapted beneficial microbes in response to elevated CO2 (eCO2) will facilitate the identification of nutrient-efficient cultivars for sustainable agriculture.Here, systematic morphological, anatomical, chemical and gene expression assays performed under low-nitrogen conditions revealed that eCO2 drove the development of the endodermal barrier with respect to L-/S-shaped lateral roots (LRs) in rice.Next, we applied metabolome and endodermal-cell-specific RNA sequencing and showed that rice adapts to eCO2 by spatially recruiting diazotrophs via flavonoid secretion in L-shaped LRs. Using the rice Casparian strip mutant Oscasp1-1, we confirmed that reduced lignin deposition selectively recruits the diazotrophic family of Oxalobacteraceae to confer tolerance to low nitrogen availability.
