Co‐evolution within the plant holobiont drives host performance

EMBO Reports, Journal Year: 2023, Volume and Issue: 24(9)

Published: July 20, 2023

Plants interact with a diversity of microorganisms that influence their growth and resilience, they can therefore be considered as ecological entities, namely "plant holobionts," rather than singular organisms. In plant holobiont, the assembly above- belowground microbiota is ruled by host, microbial, environmental factors. Upon microorganism perception, plants activate immune signaling resulting in secretion factors modulate composition. Additionally, metabolic interdependencies antagonism between microbes are driving forces for community assemblies. We argue complex plant-microbe intermicrobial interactions have been selected during evolution may promote survival fitness associated holobionts. As part this process, evolved metabolite-mediated strategies to selectively recruit beneficial microbiota. Some these members show host-adaptation, from which mutualism rapidly arise. also co-evolved antagonistic activities restrict proliferation high pathogenic potential prevent disease development. Co-evolution within holobionts thus ultimately drives performance.

Microbiomes have highly important roles for ecosystem functioning and carry out key functions that support planetary health, including nutrient cycling, climate regulation, water filtration. are also intimately associated with complex multicellular organisms such as humans, other animals, plants, insects perform crucial the health of their hosts. Although we starting to understand microbiomes in different systems interconnected, there is still a poor understanding microbiome transfer connectivity. In this review show how connected within transferred between habitats discuss functional consequences these connections. Microbiome occurs abiotic (e.g., air, soil, water) biotic environments, can either be mediated through vectors or food) direct interactions. Such processes may include transmission pathogens antibiotic resistance genes. However, here, highlight fact positive effects on human where transmitted microorganisms potentially providing novel adaptation ecosystems.

Abstract Background The severity and frequency of drought are expected to increase substantially in the coming century dramatically reduce crop yields. Manipulation rhizosphere microbiomes is an emerging strategy for mitigating stress agroecosystems. However, little known about mechanisms underlying how drought-resistant plant recruitment specific fungi enhances adaptation drought-sensitive wheats.

We then established evident linkages between root morphology traits putative keystone taxa based on inoculation experiments. Furthermore, RNA RT-qPCR were employed explore microbes modify response stresses. Results Our results indicated that host signature, niche compartment, planting site jointly contribute variation soil microbiome adaptation, with a relatively greater effect signature observed community. Importantly, wheat (Yunhan 618) possessed more diverse bacterial fungal than (Chinese Spring), particularly species. In terms interkingdom association networks, variety complex networks.

Seed biopriming for sustainable agriculture and ecosystem restoration

Microbial Biotechnology, Journal Year: 2023, Volume and Issue: 16(12), P. 2212 - 2222

Published: July 25, 2023

Abstract The utilization of microbial inoculants in the realm sustainable agricultural and ecosystem restoration has witnessed a surge recent decades. This rise is largely attributed to advancements our understanding plant–microbe interactions, urgency reduce dependence on agrochemicals growing societal demand for strategies management. However, despite rapid growth bio‐inoculants sector, certain limitations persist concerning their efficacy performance under field condition. Here, we propose that seed biopriming, an effective inoculant technique integrating both biological agents (the priming beneficial microbes seeds) physiological aspects (hydration seeds improved metabolically activity), significant potential mitigate these limitations. method increases protection against soil‐borne pathogens soil pollutants, such as salts heavy metals, while promoting germination rate uniformity, leading overall primary productivity health. Furthermore, argue coating can facilitate transgenerational associations microbes, refine plant microbiomes, maintain legacies microflora. review article aims improve biopriming approach potent valuable tool achieving agriculture successful restoration.

Seed germination is a major determinant of plant development and final yield establishment but strongly reliant on the plant’s abiotic biotic environment. In context global climate change, classical approaches to improve seed under challenging environments through selection use synthetic pesticides reached their limits. A currently underexplored way exploit beneficial impact microorganisms associated with plants. Among microbiota, endophytes, which are micro-organisms living inside host tissues without causing any visible symptoms, promising candidates for improving fitness. They possibly establish mutualistic relationship host, leading enhanced improved tolerance threats pathogen attacks. The current view that such association relies chemical mediations using large variety molecules produced by endophytes. contrast leaf root seed-borne fungal endophytes have been poorly studied although they constitute early-life microbiota. Moreover, microbiota its metabolites appear as pertinent lever quality improvement. This review summarizes recent advances in identification benefits biology, especially stress.

ABSTRACT Temporal variation in community composition is central to our understanding of the assembly and functioning microbial communities, yet controls over temporal dynamics for microbiomes long-lived plants, such as trees, remain unclear. tree could arise primarily from seasonal (i.e., intra-annual) fluctuations or longer-term changes across years host plants age. To test these alternatives, we experimentally isolated plant microbiome using a common garden clonally propagated used amplicon sequencing characterize bacterial/archaeal fungal communities leaf endosphere, root rhizosphere two Populus spp. four seasons consecutive years. Microbial differed among (which accounted up 21% composition) was correlated with dissimilarity climatic conditions. However, also positively time, reflecting compositional shifts trees aged. Together, findings demonstrate that patterns both changes, which interact generate unique each year. In addition shedding light on important microbiomes, results suggest future studies should account background when testing drivers spatial responses environmental change. IMPORTANCE Microbiomes are integral health but have limited factors control how time. Especially little known about relative annual non-woody plants.
