activating signals for some responses is the ethylene hormone , so if it is inhibited, these responses can be blocked (Figure 3 right). 6. The importance of soil microorganisms Given that, on many occasions, the deficiency of nutrients in plants is not due to their scarcity but to their low availability in the soil, we need to better understand the mechanisms for acquiring nutrients and their regulation to achieve more efficient plant varieties, which need smaller amounts of fertilizers. In this sense, it must be said that a large number of microorganisms grow around the roots, apart from the well-known nitrogen-fixing bacteria and mycorrhizae , which can contribute to the acquisition of nutrients and whose study is also essential to improve the nutrition of

plants and, therefore, ours. * This article was originally Honduras WhatsApp Number List published in The Conversation Spain on 10/13/2021 by Professor Javier Romera of the Agronomy Department and Director of the Timac AGRO Chair of Sustainable Agricultural Nutrition, University of Córdoba.A study developed at the University of Seville and led by researcher Emilio Gutiérrez, from the department of Plant Biochemistry and Molecular Biology, has yielded new data to understand how plants manage their stress situations. The ability of these living beings to adapt to different adverse conditions determines, to a large extent, their survival. Therefore, understanding how they are capable of responding and coping with these stressful conditions is crucial to design

biotechnological approaches that allow minimizing economic losses in agriculture derived from an increasingly changing climate. At the cellular level, one of the first events that occurs after the perception of the stress signal is the formation of cytoplasmic complexes composed of RNA and proteins known as stress granules. The formation of these complexes occurs as a defense mechanism to promote cell survival. Although the role of stress granules has been extensively studied in mammals, their role in plants is unknown. In a work published in 2015 in the journal The Plant Cell, it was found that the TSN protein acts as a connecting link between the assembly of stress granules and plant resistance. However, the molecular mechanism through
