Biologie synthétique
La biologie synthétique s'appuie sur l'ingénierie et la biologie moléculaire d'innover et de modifier les systèmes biologiques pour diverses applications.

La biologie synthétique intègre les principes de l'ingénierie et de la biologie moléculaire pour concevoir, construire et modifier des systèmes biologiques dotés de fonctions inédites. Elle repose sur l'assemblage de composants génétiques standardisés, la construction de circuits génétiques synthétiques et la reprogrammation du métabolisme cellulaire afin de créer des organismes ou des composants biologiques sur mesure. Parmi les techniques employées figurent l'édition du génome, la synthèse d'ADN et l'optimisation des voies métaboliques, permettant ainsi le développement d'applications thérapeutiques, de biocarburants, de biodétection et de bioproduction. Ce domaine contribue à une meilleure compréhension de la complexité du vivant grâce à la création de systèmes orthogonaux, de cellules minimales et de réseaux de régulation synthétiques. La compilation ci-dessous présente des publications et des brevets récents détaillant les innovations en matière d'outils, de méthodologies et d'applications au sein de la biologie synthétique.

Abstract: Brown spot, caused by the seedborne fungus Bipolaris oryzae, remains a major constraint in rice production. Here, we used in vitro and in vivo assays to evaluate the biocontrol potential of three Bacillus strains (Ba. cereus OQ725688.1, Ba. velezensis OP938696.1, and Ba. subtilis OP937353.1) against Bi. oryzae in two rice cultivars (&amp;ldquo;Rubelita&amp;rdquo; and &amp;ldquo;Predileta&amp;rdquo;). Ba. cereus showed the highest in vitro mycelial inhibition (&amp;asymp;95%),[...]


Our summary: Bacillus velezensis enhances rice resistance to brown spot by integrating antifungal and growth promotion functions. It effectively reduces disease severity and increases seedling vigor compared to infected controls. The strain exhibits unique biochemical traits and potential for sustainable rice protection strategies.
