“…In rice, priming with 5-aminolevulinic acid improved shoot elongation [81] while priming with picomolar rutin augmented both root and shoot length in relation to an increase in photosynthetic pigments, phenolic and flavonoid contents [82]. In wheat, priming with sodium prusside stimulated plant growth as a consequence of improved capacity to scavenge free radicals by antioxidants [83], and a similar observation was reported for rice as a result of an increase in glutathione peroxidase (GPX) activity [24] and other antioxidant enzyme activities [84].…”

“…Frequently, such improvement is obvious just after emergence at the seedling level, but progressively disappears at the adult stage. For example, some young plants issued from priming treatments displayed improvement of resistance to chilling [84], low temperature [75], salinity [43,102], high temperature [80], drought [24,65,103], and UV exposure [82]. Some interesting studies also demonstrated that priming may afford resistance to biotic stresses such as Fusarium oxysporum in tomato [104], viral disease in Brassica rapa [105], and downy mildew in pearl millet [106].…”

Seed priming is a pre-sowing treatment which leads to a physiological state that enables seed to germinate more efficiently. The majority of seed treatments are based on seed imbibition allowing the seeds to go through the first reversible stage of germination but do not allow radical protrusion through the seed coat. Seeds keeping their desiccation tolerance are then dehydrated and can be stored until final sowing. During subsequent germination, primed seeds exhibit a faster and more synchronized germination and young seedlings are often more vigorous and resistant to abiotic stresses than seedlings obtained from unprimed seeds. Priming often involves soaking seed in predetermined amounts of water or limitation of the imbibition time. The imbibition rate could be somehow controlled by osmotic agents such as PEG and referred as osmopriming. Halopriming implies the use of specific salts while "hormopriming" relies on the use of plant growth regulators. Some physical treatments UV, cold or heat,.. also provide germination improvement thus suggesting that priming effects are not necessarily related to seed imbibition. " better understanding of the metabolic events taking place during the priming treatment and the subsequent germination should help to use this simple and cheap technology in a more efficient way.

“…The improved germination characteristics are attributed to the activation of priming-induced metabolic activities, referred to as "priming memory", including de novo synthesis of nucleic acids and proteins, ATP production, restoration of antioxidant activities, and cellular repair [11]. Previous studies about seed priming mainly focused on its benefits, involving germination features, antioxidant process, cell cycle and cell structures, and expression of genes and proteins, against various abiotic stresses including drought, heavy metals, and chilling [10,12,13]. Very few researches have payed attention to the effects of artificially aging and subsequent priming, but only at germination and seedling growth, antioxidant enzymes' activities, and seed reservoirs in species, such as cucumber (Cucumis sativa L.) [14] and maize (Zea maize L.) [9].…”

Although melatonin has been reported to play an important role in regulating metabolic events under adverse stresses, its underlying mechanisms on germination in aged seeds remain unclear. This study was conducted to investigate the effect of melatonin priming (MP) on embryos of aged oat seeds in relation to germination, ultrastructural changes, antioxidant responses, and protein profiles. Proteomic analysis revealed, in total, 402 differentially expressed proteins (DEPs) in normal, aged, and aged + MP embryos. The downregulated DEPs in aged embryos were enriched in sucrose metabolism, glycolysis, β-oxidation of lipid, and protein synthesis. MP (200 μM) turned four downregulated DEPs into upregulated DEPs, among which, especially 3-ketoacyl-CoA thiolase-like protein (KATLP) involved in the β-oxidation pathway played a key role in maintaining TCA cycle stability and providing more energy for protein translation. Furthermore, it was found that MP enhanced antioxidant capacity in the ascorbate-glutathione (AsA-GSH) system, declined reactive oxygen species (ROS), and improved cell ultrastructure. These results indicated that the impaired germination and seedling growth of aged seeds could be rescued to a certain level by melatonin, predominantly depending on β-oxidation, protein translation, and antioxidant protection of AsA-GSH. This work reveals new insights into melatonin-mediated mechanisms from protein profiles that occur in embryos of oat seeds processed by both aging and priming.

“…Thus, primed plants show faster and/or stronger activation of defence responses when subsequently challenged by abiotic/biotic stress, and this is frequently linked to development of local and systemic immunity and stress tolerance (Conrath, ; Islam et al , ). Previously, seed priming with SA was applied to improve seedling growth and the antioxidant defence system in sweet sorghum under high temperature and salinity (Nimir et al , ), as well as chilling tolerance in rice seedlings (Pouramir‐Dashtmian et al , ). In addition, seed treatment with SA resulted in decreased charcoal rot disease caused by fungi in sunflowers (Al‐Wakeel et al , ).…”

The root holoparasitic angiosperm sunflower broomrape (Orobanche cumana) specifically affects sunflower (Helianthus annuus) growth and causes severe damage all over the world. This investigation was designed to examine the protective effects of salicylic acid (SA) treatment to the seeds of an O. cumana-susceptible cultivar of sunflower (TK0409). Sunflower seeds were pretreated with different concentrations (0, 0.5 and 1 mM) of SA and inoculated with O. cumana for 4 weeks. O. cumana infection resulted in reduction in plant biomass, endogenous SA level, and the expression of SA-related genes including pal, chs and NPR1. By contrast, O. cumana infection enhanced the production of reactive oxygen species, activities of antioxidant enzymes as well as contents of phenolics and lignin. Seed treatment with 1 mM SA increased sunflower biomass in terms of plant height, fresh weight and dry weight by 10%, 13% and 26%, respectively, via reducing the number and biomass of established O. cumana. The increase of hydrogen peroxide contents by 14% in the 1 mM SA treated sunflower plants appeared to be because of the inhibition of ascorbate peroxidase and catalase by exogenous SA. The enhanced expression of pathogenesis-related genes (PR3 and PR12, encoding chitinase and defensin, respectively) after 4 weeks of inoculation indicated that systemic acquired resistance was induced in the SA treated sunflower in which the level of endogenous SA was also elevated in a dose-dependent manner. The increased expression of a hypersensitive-responsive (HR) gene hsr indicated that the resistance of sunflowers might be associated with a hypersensitive reaction which was activated by exogenous SA treatment.(H 2 O 2 ) in O. cumana-infected sunflowers promote an oxidative burst during the interaction of sunflower and O. cumana . Rapid production of ROS is seen as an indicator of successful recognition of infection by plants, leading to the activation of the plants' defence mechanism (Torres et al., 2006;Torres, 2010). Accumulation of H 2 O 2 in peas infected by Orobanche crenata was observed by using both biochemical and cytochemical techniques (Pérez-de-Luque et al., 2006;Mabrouk et al., 2007). However, Mor et al. (2008) found that ROS detected at the interaction site on Arabidopsis thaliana infected by Orobanche aegyptiaca probably originated from the parasite, which was important for 408 Ann Appl Biol 169 (2016) 408-422
