| description | Abstract Background Climate change alters modern drought episode patterns by making them longer, more frequent and more severe, in particular in arid and semi-arid agroecosystems. Amending soil properties and enhancing its fertility is a needed sustainable strategy for mitigating drought’s damaging effects on crop production and food security. Here, we planned to investigate the potential benefits of biochar–compost mixture (B×C) as a biochar-based fertilizer (BCF) in enhancing the drought tolerance of rice plants cultivated in low-fertile sandy soil. Results Under drought stress, rice plants cultivated in unamended soil (no B×C) exhibited severely wilted, rolled and discolored shoots. Furthermore, the shoot dry biomass reduction ratio was 73.3% compared to 44.2 and 27.6% for plants treated with 5 and 15% B×C, respectively. Root anatomical and architectural traits were significantly less impaired in B×C plants and reflected better performance under drought compared to no B×C plants. During the induced drought episode, soil moisture content was enhanced by 2.5-fold through adding B×C, compared to unamended soil, thereby reducing the negative impact of drought stress. Moreover, the less drought-stressed rice plants (B×C-treated) rapidly recovered after rewatering and displayed the unwinding of previously rolled leaves and reproduced panicles. On the other hand, no B×C plants failed to recover and eventually perished completely. The expression profiles of several drought responsive genes suggest that leaves of more stressed rice plants (no B×C) significantly accumulated more cytosolic free calcium (OsCML3) and apoplastic H2O2 (OsOXO4) which eventually may trigger fast and prolonged stomatal closure (OsSRO1c). In addition, more drought-stressed plants (no B×C) may over-produce the reactive oxygen species (ROS) superoxide anion molecules (OsRbohB), the negative situation that has been further complicated by a possible reduction in the activity of the antioxidative enzyme SOD (OsSOD), and thus more lipid peroxidation (3.5-fold increase MDA) in drought-stressed (no B×C) plant shoots compared to B×C plants. Conclusion It is suggested that soil amendment B×C (biochar–compost mixture) could promote drought stress tolerance in rice plants by retaining more soil moisture content, thereby mitigating the negative effects of drought stress, such as the over-production of ROS in leaves, and thus eventually facilitating recovery after rewatering. |
