Epiphytic microbes are those that live for some or all of their life cycle on the surface plant leaves. Leaf surfaces a topologically complex, physicochemically heterogeneous habitat is home to extensive, mixed communities resident and transient inhabitants from three domains life. In this review, we discuss origins leaf how different biotic abiotic factors shape communities.

Uncovering New Insights and Misconceptions on the Effectiveness of Phosphate Solubilizing Rhizobacteria in Plants: A Meta-Analysis

Frontiers in Plant Science, Journal Year: 2022, Volume and Issue: 13

Published: March 2, 2022

As the awareness on ecological impact of chemical phosphate fertilizers grows, research turns to sustainable alternatives such as implementation solubilizing bacteria (PSB), which make largely immobile phosphorous reserves in soils available for uptake by plants. In this review, we introduce mechanisms plants facilitate P-uptake and illustrate how PSB improve bioavailability nutrient. Next, effectiveness increasing plant biomass is assessed using a meta-analysis approach. Our review demonstrates that improved does not always translate height biomass. We show effect provide an added benefit when bacterial consortia compared single strains. Moreover, commonly reported species P-solubilization, Bacillus spp. Pseudomonas spp., are outperformed scarcely implemented Burkholderia Despite similar responses monocots eudicots, responsiveness varies within both clades. Remarkably, challenges common belief less effective under field conditions greenhouse conditions. This provides innovative insights identifies key questions future promote their agriculture.

Serratia marcescensPLR enhances lateral root formation through supplying PLR-derived auxin and enhancing auxin biosynthesis in Arabidopsis

Journal of Experimental Botany, Journal Year: 2022, Volume and Issue: 73(11), P. 3711 - 3725

Published: Feb. 22, 2022

Plant growth promoting rhizobacteria (PGPR) refer to bacteria that colonize the rhizosphere and contribute plant or stress tolerance. To further understand molecular mechanism by which PGPR exhibit symbiosis with plants, we performed a high-throughput single colony screening from rhizosphere, uncovered bacterium (named lateral root, PLR) significantly promotes Arabidopsis root formation. By 16S rDNA sequencing, PLR was identified as novel sub-species of Serratia marcescens. RNA-seq analysis integrated phenotypic verification auxin signalling mutants demonstrated effect on formation is dependent signalling. Furthermore, enhanced tryptophan-dependent indole-3-acetic acid (IAA) synthesis inducing multiple biosynthesis genes in Arabidopsis. Genome-wide sequencing identification IAA its precursors exudates showed tryptophan treatment ability produce precursors. Interestingly, induced expression nutrient (N, P, K, S) transporter an auxin-independent manner. This study provides evidence how enhances through fine-tuning Arabidopsis, implying potential application crop yield improvement accelerating development.

Ribosomally synthesized peptides, foreground players in microbial interactions: recent developments and unanswered questions

Natural Product Reports, Journal Year: 2021, Volume and Issue: 39(2), P. 273 - 310

Published: Nov. 10, 2021

It is currently well established that multicellular organisms live in tight association with complex communities of microorganisms including a large number bacteria. These are immersed interaction networks reflecting the relationships between them and host organisms; yet, little known about molecules mechanisms involved these mutual interactions. Ribosomally synthesized peptides, among which bacterial antimicrobial peptides called bacteriocins microcins have been identified as contributing to host-microbe interplays, either unmodified or post-translationally modified peptides. This review will unveil current knowledge on ribosomal peptide-based natural products, their interplay immune system, roles microbial interactions symbioses. include major structural characteristics post-translational modifications, main rules maturation pathways, principal ecological functions they ensure (communication, signalization, competition), especially symbiosis, taking select examples various organisms. Finally, we address unanswered questions provide framework for deciphering big issues inspiring future directions field.
