“…3 , asterisks) suggest that this phenomenon may be associated with the structure and thickness of the peptidoglycan cell wall layer. Actinoplanes , an Actinobacteria that is a notable exception to the general drought enrichment observed for this phylum, has recently been shown to have a novel cell wall type with considerable alterations in peptidoglycan structure compared with the majority of other actinobacterial lineages ( 52 , 53 ). Within the Proteobacteria, a largely diderm phylum with strong and near-exclusive depletion under drought, some members of the order Chromatiales and the family Myxococcaceae are known to possess additional or unusual layers within their peptidoglycan cell wall ( 54 , 55 ); correspondingly, we observe a strong enrichment under drought for both.…”

SignificanceDrought remains a critical obstacle to meeting the food demands of the coming century. Understanding the interplay between drought stress, plant development, and the plant microbiome is central to meeting this challenge. Here, we demonstrate that drought causes enrichment of a distinct set of microbes in roots, composed almost entirely of monoderms, which lack outer membranes and have thick cell walls. We demonstrate that under drought, roots increase the production of many metabolites, and that monoderms inhabiting the drought-treated rhizosphere exhibit increased activity of transporters connected with some of these same compounds. The discovery of this drought-induced enrichment and associated shifts in metabolite exchange between plant and microbe reveal a potential blueprint for manipulating plant microbiomes for improved crop fitness.

“…The genus Nocardiopsis comprises seven species including N. dassonvillei and N. albus subsp. albus (Altai & Ruan, 1994). Earlier, we studied the cell-wall teichoic acid from 15 strains of N. dassonvillei and showed that all the strains contained the same polymers of unique structure, hitherto never found in bacterial cell walls (Tul´skaya et al, 1993; Akimov et al, 1994).…”

Pus hc h i no, Moscow Region, RussiaCell walls of the three Nocardiopsis albus subsp. albus strains, DSM 43377? 43378 and 43120 contain structurally identical teichoic acids. The cell wall of each strain has three distinct types of teichoic acids: (1) unsubstituted 3,5-poly(ribito1 phosphate), (2) 1,3-poly(glycerol phosphate) partially substituted at C-2 with a-N-acetylglucosamine residues, and (3) 1,5-poly(ribitol phosphate) with each ribitol unit carrying a 2,&pyruvate ketal group. Types 1 and 3 are reported in prokaryotes for the first time. The structure of the teichoic acids was elucidated by chemical analysis and NMR-spectroscopic methods. Structural identity of the teichoic acids from the three strains belonging to the same species may demonstrate the species-specif icity of these polymers.
