“…On the contrary, melatonin treatment increases gibberellic acid (GA) synthesis and GA content under abiotic stress conditions including drought stress (Khan et al, 2020;Zhan et al, 2019). Recently, the GA3 and MT-primed rapeseed plants Foliar spray (100 μM) positive regulation of 24-epibrassinolide Sharma et al (2020) have been shown to exhibit improved morphological traits, yield and yield components, and seed qualitative attributes compared to noprimed plants under the drought stress (Khan et al, 2020). Melatonin is not only in cross-talk with GAs via GA-signaling, but further regulates the auxin biosynthetic pathway (Wei et al, 2017).…”

“…Recently, several reports showed that melatonin treatment has enhanced the enzymatic antioxidants CAT, APX, MDHAR, and DHAR activities in maize (Alharby & Fahad, 2020); CAT, POD, SOD, and APX activities in buckwheat (Hossain et al, 2020); GT, CAT, POD, SOD, and GR activities in Salvia sp. (Bidabadi et al, 2020); indole acetic acid and phenolic contents; TSS, CAT, POD, and SOD activities in flax plants (Sadak et al, 2020); proline content and antioxidant CAT, POD, SOD, and GR activities in rapeseed (Khan et al, 2020); root catalase activity in rapeseed (Dai et al, 2020); and acid and alkaline invertase activities in anthers of cotton (Hu et al, 2020). Melatonin‐mediated activation of proline stimulates drought adaptations through a stabilized cell membrane and reduced ROS accumulation (Wang et al, 2019).…”

“…Enzymatic systems are composed of a set of SOD (antioxidant enzymes including superoxide dismutase), POD (peroxidase), CAT (catalase), and APX (ascorbate peroxidase), etc. Non-enzymatic systems, for example, include small organic molecules such as glutathione [18], mannitol [19], and melatonin [20,21], and can effectively scavenge ROS in plant cells. However, the energy cost of the synthesis of such compounds and compatible solutes is high.…”

“…Rapeseed ( Brassica napus L.) is one of the important oilseed crops in the world [ 1 ]. In the past decade, the Brassica napus total harvested area, productivity, and annual grain yield increased by 17.6% (29.5–34.7 million ha), 50.3% (50.6–76.1 million tons), and 27.8% (1716–2194 kg ha −1 ) respectively, reflecting that the demand for Brassica napus is continuing to increase [ 2 ].…”

“…Seed priming enhances antioxidant enzymes activities and reduces lipid peroxidation [ 10 ]. Besides priming for disease control [ 13 ] and nutrient supply [ 14 ], seeds can be also imbibed in a solution containing certain solutes such as salt [ 15 ], mannitol [ 16 ], and PEG [ 10 ] etc., for the activation of pre-germinative metabolism while not allowing the seed to the fully germination stage [ 1 ]. Among the priming techniques, seed nanopriming which uses nanomaterials to prime seeds, has been reported to be successfully applied for improving germination and stress tolerance of seedlings [ 17 ].…”
