Top-down and bottom-up cohesiveness in microbial community coalescence

Proceedings of the National Academy of Sciences, Год журнала: 2022, Номер 119(6)

Опубликована: Фев. 1, 2022

Significance In the microbial world, it is common for previously isolated communities to come in contact with one another. This phenomenon known as community coalescence. Despite being a key process assembly of communities, little about mechanisms that determine its outcomes. Here we present an experimental system allowed us study over 100 coalescence events between segregated microbiomes. Our results, predicted by mathematical model, provide direct evidence ecological coselection: situation where members recruit another during combined and theoretical framework represents powerful tool predict outcomes interrogate

Ecological and Evolutionary Implications of Microbial Dispersal

Frontiers in Microbiology, Год журнала: 2022, Номер 13

Опубликована: Апрель 6, 2022

Dispersal is simply defined as the movement of species across space and time. Despite this terse definition, dispersal an essential process with direct ecological evolutionary implications that modulate community assembly turnover. Seminal studies have shown environmental context (e.g., local edaphic properties, resident community), timing frequency, traits, collectively account for patterns distribution resulting in either their persistence or unsuccessful establishment within communities. key importance process, relatively little known about how operates microbiomes divergent systems types. Here, we discuss parallels macro- micro-organismal ecology a focus on idiosyncrasies may lead to novel mechanisms by which affects structure function microbiomes.

Artificial Selection on Microbiomes To Breed Microbiomes That Confer Salt Tolerance to Plants

Опубликована: Ноя. 30, 2021

We develop a method to artificially select for rhizosphere microbiomes that confer salt tolerance the model grass Brachypodium distachyon grown under sodium stress or aluminum stress. In controlled greenhouse environment, we differentially propagated between plants of nonevolving, highly inbred plant population; therefore, only evolved in our experiment, but did not evolve parallel. To maximize microbiome perpetuation when transplanting and, thus, response selection, improved earlier methods by (i) controlling assembly inoculating seeds at beginning each selection cycle; (ii) fractionating before transfer harvest, perpetuate, and on bacterial viral components; (iii) ramping gradually from minor extreme with cycle minimize chance overstressing plants; (iv) using two nonselection control treatments (e.g., microbial enrichment null inoculation) permit comparison improving fitness benefits selected impart plants.

Contrary effects of increasing temperatures on the spread of antimicrobial resistance in river biofilms

Опубликована: Фев. 7, 2024

River microbial communities regularly act as the first barrier of defense against spread antimicrobial resistance genes (ARGs) that enter environmental microbiomes through wastewater. However, how invasion dynamics wastewater-borne ARGs into river biofilm will shift due to climate change with increasing average and peak temperatures remains unknown. Here, we aimed elucidate effects on naturally occurring resistome, well success foreign entering Natural biofilms were grown in a low-anthropogenic impact transferred artificial laboratory recirculation flume systems operated at three different (20°C, 25°C, 30°C). After 1 week temperature acclimatization, significant increases abundance detected higher temperatures. this acclimatization period, exposed single pulse wastewater, analyzed over 2 weeks. day, able invade successfully no observable effect their relative abundance. thereafter, lost far increased rate 30°C, ARG levels dropping initial natural after 14 days.

A new flavor of synthetic yeast communities sees the light

ABSTRACT No organism is an island: organisms of varying taxonomic complexity, including genetic variants a single species, can coexist in particular niches, cooperating for survival while simultaneously competing environmental resources. In recent years, synthetic biology strategies have witnessed surge efforts focused on creating artificial microbial communities to tackle pressing questions about the complexity natural systems and interactions that underpin them. These engineered ecosystems depend number nature their members, allowing complex cell communication designs recreate create diverse interest. Due its experimental simplicity, budding yeast Saccharomyces cerevisiae has been harnessed establish mixture varied populations with potential explore ecology, metabolic bioprocessing, biosensing, pattern formation. Indeed, enable advanced molecule detection dynamics logic operations. Here, we present concise overview state-of-the-art, highlighting examples exploit optogenetics manipulate, through light stimulation, key phenotypes at community level, unprecedented spatial temporal regulation. Hence, envision bright future where application optogenetic approaches (optoecology) illuminates intricate drives innovations engineering strategies.
