    Rice is a first- or second-order staple food in many countries. It is mainly produced and consumed in Asia. There are so many causes of low yield of rice crops in the world. However, abiotic and biotic stresses are major factors for reducing rice yield and quality. The stresses’ share in reducing rice yield across various regions varies greatly. So, in order to adapt to and mitigate climate change, both short-term and long-term approaches are needed for ensuring food security at regional and global levels. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.

    Seed Priming and Foliar Supplementation with?-aminobutyric Acid Alleviates Drought Stress through Mitigation of Oxidative Stress and Enhancement of Antioxidant Defense in Linseed (Linum usitatissimum L.)

    Drought is one of the critical limitations to agricultural soils and crop plants. Scarcity of water is increasing due to climate change that lead to increasing threats to global food security. Therefore, ecofriendly and cost effective strategies are highly desirable for mitigating drought stress along with sustainable and smart agricultural production. The aim of the study was to mitigate DS using seed priming and exogenous supplementation of beta-amino-butyric acid (BABA) in linseed (Linum usitatissimum L.). Different doses (0, 50, 100 and 150 mu M) of BABA were used for seed priming agent and foliar spraying under three soil moisture levels viz., 25% (SM25), 45% (SM45) and 65% (SM65). The response variables of both experiments included different agro-botanical traits and oxidative stress indicators such as melondialdehyde content, free proline accumulation, and antioxidant defense in plants. The linseed plants showed water stress at SM25 that reduced plant height, number of branches per plant, time taken to flower initiation and heading, and root and shoot dry weights. Additionally, the number of capsules and seeds per capsule showed a significant decline at SM25, which led to a drastic reduction in 100-seed weight yield in linseed plants in both experiments. However, seed priming and foliar supplementation with of BABA (50-100 mu M) significantly improved these morpho-agronomical attributes in linseed plants under DS. The results revealed that the BABA was fully active in linseed plants at SM25. Interestingly, the combination of SM25 with BABA significantly improved the antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and peroxidase (POD) activity, which significantly enhanced DS tolerance in linseed plants. These findings might be useful to oil seed breeders and farmers linseed for breeding program in linseed plants as well as sustainable agricultural production of oil seed crop plants.
