The Plant Microbiota: Systems-Level Insights and Perspectives

Annual Review of Genetics, Год журнала: 2016, Номер 50(1), С. 211 - 234

Plants do not grow as axenic organisms in nature, but host a diverse community of microorganisms, termed the plant microbiota. There is an increasing awareness that microbiota plays role growth and can provide protection from invading pathogens. Apart intense research on crop plants, Arabidopsis emerging valuable model system to investigate drivers shaping stable bacterial communities leaves roots tool decipher intricate relationship among its colonizing microorganisms. Gnotobiotic experimental systems help establish causal relationships between genotypes phenotypes test hypotheses biotic abiotic perturbations systematic way. We highlight major recent findings using comparative profiling omics analyses, discuss these approaches light establishment beneficial traits like nutrient acquisition health.

Research priorities for harnessing plant microbiomes in sustainable agriculture

PLoS Biology, Год журнала: 2017, Номер 15(3), С. e2001793 - e2001793

Опубликована: Март 28, 2017

Feeding a growing world population amidst climate change requires optimizing the reliability, resource use, and environmental impacts of food production. One way to assist in achieving these goals is integrate beneficial plant microbiomes—i.e., those enhancing growth, nutrient use efficiency, abiotic stress tolerance, disease resistance—into agricultural This integration will require large-scale effort among academic researchers, industry farmers understand manage plant-microbiome interactions context modern systems. Here, we identify priorities for research this area: (1) develop model host–microbiome systems crop plants non-crop with associated microbial culture collections reference genomes, (2) define core microbiomes metagenomes systems, (3) elucidate rules synthetic, functionally programmable microbiome assembly, (4) determine functional mechanisms interactions, (5) characterize refine genotype-by-environment-by-microbiome-by-management interactions. Meeting should accelerate our ability design implement effective manipulations management strategies, which, turn, pay dividends both consumers producers supply.

Understanding and exploiting plant beneficial microbes

Current Opinion in Plant Biology, Год журнала: 2017, Номер 38, С. 155 - 163

Опубликована: Июнь 14, 2017

After a century of incremental research, technological advances, coupled with need for sustainable crop yield increases, have reinvigorated the study beneficial plant-microbe interactions attention focused on how microbiomes alter plant phenotypes. We review recent advances in microbiome and describe potential applications increasing productivity. The phylogenetic diversity is increasingly well characterized, their functional becoming more accessible. Large culture collections are available controlled experimentation, to come. Genetic resources being brought bear questions function. expect that microbial amendments varying complexities will expose rules governing contributing growth promotion disease resistance, enabling agriculture.

Simplified and representative bacterial community of maize roots

Proceedings of the National Academy of Sciences, Год журнала: 2017, Номер 114(12)

Опубликована: Март 8, 2017

Plant-associated microbes are important for the growth and health of their hosts. As a result numerous prior studies, we know that host genotypes abiotic factors influence composition plant microbiomes. However, high complexity these communities challenges detailed studies to define experimentally mechanisms underlying dynamics community assembly beneficial effects such microbiomes on In this work, from distinctive microbiota assembled by maize roots, through host-mediated selection, obtained greatly simplified synthetic bacterial consisting seven strains (Enterobacter cloacae, Stenotrophomonas maltophilia, Ochrobactrum pituitosum, Herbaspirillum frisingense, Pseudomonas putida, Curtobacterium pusillum, Chryseobacterium indologenes) representing three four most dominant phyla found in roots. By using selective culture-dependent method track abundance each strain, investigated role plays roots axenic seedlings. Only removal E. cloacae led complete loss community, C. pusillum took over. This suggests keystone species model ecosystem. planta vitro, inhibited phytopathogenic fungus Fusarium verticillioides, indicating clear benefit host. Thus, combined with quantification method, our seven-species root microbiome has potential serve as useful system explore how interspecies interactions affect dissect hosts under laboratory conditions future.

Getting the Hologenome Concept Right: an Eco-Evolutionary Framework for Hosts and Their Microbiomes

mSystems, Год журнала: 2016, Номер 1(2)

Опубликована: Март 30, 2016

Given the complexity of host-microbiota symbioses, scientists and philosophers are asking questions at new biological levels hierarchical organization-what is a holobiont hologenome? When should this vocabulary be applied? Are these concepts null hypothesis for host-microbe systems or limited to certain spectrum symbiotic interactions such as host-microbial coevolution? Critical discourse necessary in nascent area, but productive requires that skeptics proponents use same lexicon. For instance, critiquing hologenome concept not synonymous with coevolution, arguing an entity primary unit selection dismisses fact has always embraced multilevel selection. Holobionts hologenomes incontrovertible, multipartite entities result from ecological, evolutionary, genetic processes various levels. They restricted one special process constitute wider framework host biology light microbiome.
