This article reports the first successful marker-free genetic engineering of Trichoderma harzianum, a widely studied biocontrol agent with great potential for use in sustainable agriculture. T. harzianum has been shown to control plant diseases, promote plant growth, and improve plant tolerance to abiotic stress. A specific CRISPR/Cas9 gene-editing system, based in self-replicative AMA1-plasmid, was used to generate T. harzianum mutant strains, targeting the albA (pks4) and ku70 genes, involved in melanin synthesis and non-homologous end joining DNA repair pathway, respectively. The resulting albA-deficient strain displayed a loss of pigmentation in their conidia, confirming phenotypically and genotypically the efficacy of the CRISPR/Cas9 system in generating targeted gene knockouts in T. harzianum. A marker-free ?ku70 strain was also constructed, with the maintenance of its original fitness, providing a helpful tool for precise genetic engineering in T. harzianum, due to NHEJ-deficiency, able to be used in in vitro and in vivo (in planta) studies. The study highlights the potential of using CRISPR/Cas9 technology to facilitate the study of the molecular processes involved in the biocontrol and plant growth-promoting properties of T. harzianum. |

Abstract: The aim of this study was to investigate whether microalgae in Japanese quail feed al‐ters performance, fatty acid profiles in the eggs and egg quality. One hundred quails were distributed in four groups and five replicates of five birds per experimental group. The treatments consisted of four levels of Spirulina platensis microalgae (0%, 5%, 10%, and 15%) in the diets. We evaluated the productive performance and chemical‐physical characteristics of eggs, the oxidant/antioxidant status in egg yolks, and the fatty acid profile in the diet and egg yolks. Microalgae in the diet did not influence egg production; however, it increased the yolk index as well as the color intensity of the yolk. Saturated and polyunsaturated fatty acid levels decreased in egg yolks, and monounsaturated fatty acid levels increased in the yolks. Lipid peroxidation levels were lower and total antioxidant capacity was higher in egg yolks of quails receiving microalgae in the diet. Practical applications: Microalgae in quail diets improves egg quality and provides benefits to consumer health, acting as an antioxidant and immune‐stimulant. Microalgae in quail diets had positive effects on egg quality. This is because it reduced levels of saturated fatty acids that are undesirable, and increased monounsaturated fatty acid levels that are beneficial to the health of consumers. Finally, antioxidants increased in egg yolks, consequently reducing lipid peroxidation. |
