| Titre : | GENOMIC ANALYSIS OF TWO BACILLUS STRAINS: BACILLUS VELEZENSIS QA2 AND BACILLUS LICHENIFORMIS QA1, AND IDENTIFICATION OF POTENTIAL GENES INVOLVED IN PHOSPHORUS SOLUBILIZATION | | Type de document : | thèse | | Auteurs : | EZZAHIDI OUMAIMA, Auteur | | Année de publication : | 2024 | | Langues : | Anglais (eng) | | Mots-clés : | Phosphorus Comparative genomics Bacillus licheniformis Bacillus velezensis WGS Phosphore Génomique comparative Bacillus licheniformis Bacillus velezensis WGS الفوسفور الجينوميات المقارنة باسيلوس ليشنيفورميس باسيلوس فيليزينس التسلسل الجينومي الكامل | | Résumé : | Phosphorus, essential for agricultural productivity, is often inaccessible to plants due to its insoluble forms in soil. To address this challenge, our research undertakes a detailed genomic characterization of Bacillus velezensis QA2 and Bacillus licheniformis QA1. Known for their plant growth-promoting rhizobacteria (PGPR) traits, these strains are promising candidates for developing eco-friendly biofertilizers capable of effective phosphate solubilization.
Using advanced high-throughput whole genome and Sanger sequencing technologies, we compared the genetic structures of B. velezensis QA2 and B. licheniformis QA1 to uncover specific genetic mechanisms that facilitate phosphate mobilization. Our discoveries reveal a complex network of genes responsible for the production of organic acids and phosphatases, which play important roles in transforming insoluble phosphates into forms accessible to plants. This genetic framework enhances our understanding of B. velezensis QA2's role in promoting plant growth and its potential to reduce dependence on chemical fertilizers.
This genomic exploration significantly enriches our understanding of microbial capabilities in soil nutrient dynamics, highlighting the potential of microbial genomics in advancing sustainable agricultural technologies. By elucidating the molecular mechanisms through which these bacteria enhance soil fertility, the study lays the groundwork for targeted genetic enhancements and the strategic application of Bacillus strains in agriculture. These insights position B. velezensis QA2 and B. licheniformis QA1 as a key component in the future of biofertilizer technology, transforming agricultural practices towards sustainability. | | Numéro (Thèse ou Mémoire) : | MM0232024 | | Président : | OUADGHIRI Mouna | | Directeur : | Joann Karen WHALEN, Um6p ; ERRAFII Khaoula, Um6p (AGC | | Juge : | KANDOUSSI Ilham | | Juge : | AANNIZ Tarik |
