Ef fect of rhizobacteria isolated from Suaeda sp. in the growth of Arabidopsis thaliana and Solanum lycopersicum L. (Sahariana)

The rhizosphere of the great diversity of plants is a complex ecosystem that houses thousands of rhizobacteria that promote plant growth. In the current investigation, three bacteria were isolated from the root of Suaeda sp., which were evaluated to determine the ef fect of their inoculation on Arabidopsis thaliana at distances of 2 and 5 cm and in divided boxes. In the 2 cm test, we noticed that Endo10(7) and Endo10(5) stimulated the plants more than the control, while the proximity to Ecto10(6) caused them to wilt and die. However, at 5 cm, the bacterium that most promoted the development of Arabidopsis was Ecto10(6). In the divided box test, all three bacteria showed the ability to promote growth. In addition, a shade mesh assay was carried out with the inoculation of the bacteria in Solanum lycopersicum L. (Sahariana) and it was found that the promoting ef fect was also observed in the germination and growth of tomato plants. Tests were conducted to determine its ability to produce IAA, siderophores, and solubilize phosphates. Through molecular techniques it was confirmed: the identity of Ecto10(6), Endo10(7), and Endo10(5) as Aneurinibacillus migulanus, Staphylococcus sp. and Bacillus cereus, respectively. Our results provide the rationale for suggesting that these rhizobacteria may increase the growth and development of Arabidopsis thaliana and Solanum lycopersicum

Aprendizajes Esperados: Una Educación Efectiva con Estrategias en Hábitos de Lectura

The habit of reading is a cornerstone in the learning process, because before it expands a horizon of opportunities for the acquisition of knowledge of our students, it is very useful and fundamental for our daily life, social, emotional, and academic development. From the perspective of Pérez (2018), the development of a reading habit is influenced by elements such as interest, personal preferences, and academic motivation, he also states that reading is a habit that produces pleasure and fun. The present research highlights the benefits that the habit of reading brings to young students of middle and high school education (EMS). In general terms, the methodology used to carry out this study, due to its characteristics, corresponds to a non-experimental, quantitative, correlational research; with which it was possible to collect, through the application of surveys and interviews, the necessary information to assertively reach the objective of this research: "To identify learning strategies that favor the reading habits of second semester students of the Centro de Bachillerato Tecnológico Agropecuario No. 25 and to analyze how it is related to the expected learning of the subjects they are currently studying".El hábito de lectura es pieza angular en el proceso de aprendizaje, pues ante él se expande un horizonte de oportunidades para la adquisición de conocimiento de nuestros educandos, es muy útil y fundamental para nuestra vida diaria, desarrollo social, emocional y académico; desde la perspectiva de Pérez (2018), en el desarrollo de un hábito lector intervienen factores como el interés, las preferencias personales y la motivación académica, además afirma que la lectura es un hábito que proporciona placer y diversión. La presente investigación resalta las bondades que el hábito de la lectura aporta a los jóvenes estudiantes de Educación Media Superior (EMS). En términos generales, la metodología utilizada para la ejecución de este estudio, corresponde por sus características a una investigación no experimental, de corte cuantitativo, correlacional; con la cual se logró recopilar, mediante la aplicación de cuestionarios y entrevistas, la información necesaria para alcanzar de manera asertiva el objetivo de esta exploración: “Establecer estrategias de aprendizaje que favorezcan los hábitos de lectura en alumnos de segundo semestre del Centro de Bachillerato Tecnológico Agropecuario No. 25 y analizar de qué manera se relaciona con el aprendizaje esperado de las asignaturas que cursan actualmente”
