[0000-0001-6549-3545] Symbiosis Diaporthe Drought stress Fungi Antioxidant defense Nutrient uptake Proline Photosynthetic capacity 13 páginas, 7 figuras, 1 tabla Functional symbiosis with fungal endophytes can help plants adapt to environmental stress. Diaporthe atlantica is one of the most abundant fungal taxa associated with roots of Festuca rubra subsp. pruinosa, a grass growing in sea cliffs. This study aimed to investigate the ability of a strain of this fungus to ameliorate the impact of drought stress on tomato plants. In a greenhouse experiment, tomato plants were inoculated with Diaporthe atlantica strain EB4 and exposed to two alternative water regimes: well-watered and drought stress. Several physiological and biochemical plant parameters were evaluated. Inoculation with Diaporthe promoted plant growth in both water treatments. A significant interactive effect of Diaporthe-inoculation and water-regime showed that symbiotic plants had higher photosynthetic capacity, water-use efficiency, nutrient uptake (N, P, K, Fe and Zn), and proline content under drought stress, but not under well-watered conditions. In addition, Diaporthe improved the enzymatic antioxidant response of plants under drought, through an induced mechanism, in which catalase activity was modulated and conferred protection against reactive oxygen species generation during stress. The results support that Diaporthe atlantica plays a positive role in the modulation of tomato plant responses to drought stress by combining various processes such as improving photosynthetic capacity, nutrient uptake, enzymatic antioxidant response and osmo-protectant accumulation. Thus, drought stress in tomato can be enhanced with symbiotic fungi This research was supported by the European Union’s H2020 research and innovation program under the Marie Sklodowska-Curie grant agreement no. 676480; by grant PID2019-109133RB-I00 funded by MCIN/AEI/10.13039/501100011033, and by project ‘CLU2019-05 — IRNASA/CSIC Unit of Excellence’ funded by the Junta de Castilla y León and co-financed by EU (ERDF ‘Europe drives our growth’) Peer reviewed 2023-02-06T13:27:42Z 2023-02-06T13:27:42Z 2023 artículo Frontiers in Plant Science 14: 1118698 (2023) http://hdl.handle.net/10261/288381 10.3389/fpls.2023.1118698 1664-462X http://dx.doi.org/10.13039/501100004837 http://dx.doi.org/10.13039/501100014180 en #PLACEHOLDER_PARENT_METADATA_VALUE# info:eu-repo/grantAgreement/AEI/Plan Estatal de Investigación Científica y Técnica y de Innovación 2017-2020/PID2019-109133RB-I00/ES/COMPRENDIENDO EL FUNCIONAMIENTO DE LA ADAPTACION AL ESTRES AMBIENTAL Y PROMOCION DEL CRECIMIENTO EN PLANTAS SIMBIOTICAS CON ENDOFITOS MUTUALISTAS EPICHLOE Y DIAPORTHE/ Publisher's version Sí open Frontiers Media |
