Abstract Background Plants host diverse microbial communities that can significantly impact plant health.

Conclusions Overall, study introduces novel experimental approach for investigating microbiome inheritance plants. By leveraging replication field, provide new nature seed-associated wheat.

Strawberry (Fragaria × ananassa) is the most widely cultivated small berries in world. They are not only delicious, juicy, and nutritious, but also have important economic value. However, current research on endophytic bacteria related to strawberry limited. This work provides a comprehensive description of composition diversity bacterial communities three niches (root, stem, leaf) cultivars (White Elves, Tokun, Akihime). study indicated that differ significantly between belowground niche (roots) aboveground compartments (stems leaves). The richness varied for all cultivars; it decreased from root stem leaf. alpha Akihime community were lower than White Elves stems leaves. Beneficial genera, such as Ochrobacter, Bradyrhizobium, Sphingomonas, Pseudolobrys, more abundant Tokun Akihime, especially roots stems. results this provide an reference discovering new species or genetic variations improve host fitness stress tolerance. Further needed uncover interactions plants bacteria, well potential extracting bioactive compounds these bacteria.

Mangroves are one of the world’s most unique tropical coastal ecosystems. They a rich repository biological wealth, including specially adapted flora and fauna. The microbiome component this ecosystem is fascinating world that yet to be fully explored for its functional ecological inter-relationships with hosts. mangrove hidden treasure microbial diversity, without which biology incomplete. In present study, isolation cellulase-producing, endophytic Bacillus sp. from hypocotyl region viviparous seedlings described. This study urges us look into diversity propagules, by presenting glimpse member endospheric hypocotyls.

Maize (Zea mays L.) is an important cereal crop species for food, feedstock and industrial material. seeds host a suitable ecosystem endophytic bacteria, facilitating seed germination seedling growth. However, the inheritance, diversity potential function of bacteria in maize remain largely unexplored. In this study, inbred line WU109 collected during three consecutive seasons were identified using 16S rDNA sequencing. Core community composition was essentially consistent across generations two planting locations. total, 212 operational taxonomic units (OTUs) belonging to 11 phyla identified, among which proteobacteria dominant phylum. Fifty-six OTUs conserved generations. Within them, 16 core components Ralstonia solanacearum, Delftia tsuruhatensis, Bacillu svelezensis Shigella boydii, accounting 60% total abundance OTUs. COG KEGG analyses showed that mainly enriched metabolic processes, especially amino acid, carbohydrate energy metabolism. Taken together, results suggested likely co-shaped by both genetic determination environment, while constitutes endophytes due transgenerational transmission. Establishing mutualistic link between its enables exploitation enhancing production. This finding provides reference better understand inheritance maize.
