Plant endophytes, comprising non-pathogenic bacteria, fungi, and archaea, inhabit various plant parts, including roots, stems, leaves, seeds. These microorganisms play a crucial role in development by enhancing germination, growth, stress resilience. Seed particular, represent the most adapted conserved segment of microbiota, significantly influencing initial stages growth microbial community establishment. This study investigates impact environmental genotypic factors on endophytic communities Chenopodium quinoa Willd. (quinoa), crop notable for its adaptability nutritional value. We aimed to characterize core seeds roots from two distinct genotypes under well-watered (WW) water-deficit (WD) conditions, utilizing soil infusions as inoculants explore potential changes these endophytes. Our findings reveal with exhibiting high degree conservation their microbiome, even between maternal offspring seeds, specific bacterial taxa showing only minor differences. Tissue specificity emerged key factor, maintaining stable community, while exhibited more pronounced shifts, highlighting tissue-dependent patterns enrichment. The results highlight stability varying water conditions across different genotypes, emphasizing tissue shaping associations. suggest that quinoa-associated particularly those may drought Understanding dynamics plant-microbe interactions is vital developing stress-resilient varieties, supporting sustainable agricultural practices, ensuring food security face climate change challenges.

Plant-associated microbes play a crucial role in host growth, health, and stress resistance. Host plants significantly influence the assembly of their microbial communities. To examine plant provenance on bacterial composition growth promoting (PGP) properties, we compared readily culturable bacteria isolated from root interior rhizosphere Tripterygium wilfordii Hook f., woody Chinese medicinal plant, across three provenances grown different regions. Regardless growing environment, abundance endophytic colonies followed trend: Fujian > Hunan Hubei provenances. A total 227 isolates were classified into 21 genera 40 rhizosphere, with Pseudomonas and/or Bacillus as dominant genera. The taxonomic varied environments. Plants same but cultivated locations exhibited greater similarity composition. majority assayed strains displayed one or more PGP traits. Local harbored higher proportion than non-local plants. Our findings indicate that influences root-associated bacteria, particularly native environments may recruit to enhance fitness.

Unveiling changes in rhizosphere‐associated bacteria linked to the genotype and water stress in quinoa

Microbial Biotechnology, Год журнала: 2023, Номер 16(12), С. 2326 - 2344

Опубликована: Сен. 15, 2023

Abstract Drought is among the main abiotic factors causing agronomical losses worldwide. To minimize its impact, several strategies have been proposed, including use of plant growth‐promoting bacteria (PGPBs), as they demonstrated roles in counteracting stress. This aspect has little explored emergent crops such quinoa, which potential to contribute reducing food insecurity. Thus, here we hypothesize that genotype, water environment and type inoculant are determining shaping quinoa rhizosphere bacterial communities, affecting performance. address this, two different cultivars (with contrasting stress tolerance), conditions (optimal limiting conditions) soil infusions were used define relevance these factors. Different families vary genotypes identified. Certain enriched under conditions, Nocardioidaceae, highly present water‐sensitive cultivar F15, or Pseudomonadaceae, Burkholderiaceae Sphingomonadaceae, more abundant tolerant F16, also showed larger total polyphenol content. These changes demonstrate genotype root‐inhabiting suggest this species a great source PGPBs for utilization water‐liming conditions.

Abstract Background and aims The use of root-associated microorganisms emerge as a sustainable tool to enhance crop tolerance productivity under climate change, particularly in drought-affected areas. Here, the impact an inoculum based on arbuscular mycorrhizal fungi (AMF) was evaluated pepper ( Capsicum annuum L.) cultivation at varying water irrigation treatments (well-watered, reduced rain-fed) open-field conditions. Methods Agronomic ecophysiological parameters, well biochemical analyses stress markers phytohormones leaves fruit quality traits, were evaluated, along with shifts soil- microbial communities.

The sub-mountain plains area at the northern foothills of Yinshan Mountains in Inner Mongolia is an important grain producing cold and arid regions China, but due to climatic environmental factors, it has resulted a fragile ecological environment, degradation arable land, serious soil erosion. Quinoa (Chenopodium quinoa Willd.) hardy, saline tolerant crop with much higher protein content than other crops. Therefore, begun be grown on large scale region recent years. In order investigate distribution characteristics aggregates organic carbon (SOC) fields ecologically areas, four different textures, namely, sandy soil, loam, loamy clay were selected for this experiment, mass percentages aggregate particle sizes each size determined before after planting, mineralisation textures was analysed through indoor cultures. dynamic analysed. results showed that stability enhanced planting quinoa, highest percentage >2 mm 27.95% loam soil.

Abstract Humic substances have an enormous potential for regenerative agriculture to improve soil quality and plant growth. Recently developed technologies called hydrothermal humification enabled the conversion of waste into artificial humic acids, that would allow sustainable large‐scale applications. However, not much is known about effect artificially produced acid on microbiome its drought‐exposed soil. Therefore, we studied drought stress microbiota in sandy a controlled experimental design. Analyses 16S rDNA amplicon libraries by bioinformatics statistics revealed both application influenced bacterial community composition significantly, but only affected diversity. Bacterial families like Pseudomonadaceae, Peptostreptococcaceae Moraxellaceae enriched under conditions, suggest adaptation selection microbiome. Under stress, treatment kept diversity stable changed composition. We propose can community, diminish favour growth‐promoting taxa, bring sequestrate carbon
