“…Souza, personal communi cation, 2010). We tested the effect of salt stress due to the severe problems with saline soils in places where P. angulata is grown, like for example in the northeast of Brazil (De Nys et al 2005). Germination of both nonprimed and primed seeds decreased when seeds were submitted to imbibition under increasing salt concentrations up to 16 dS m -1…”

This study aimed to evaluate the effects of priming on seed germination under salt stress and gene expression in seeds and seedlings of P. angulata L. After priming for 10 days, seed germination was tested in plastic trays containing 15 ml of water (0 dS m -1 -control) or 15 ml of NaCl solution (2, 4, 6, 8, 10, 12, 14 and 16 dS m -1). Fresh and dry weight of shoots and roots of seedlings were evaluated at 0, 2, 4, 6, 8 dS m -1 . Total RNA was extracted from whole seeds and seedlings followed by RT-qPCR. The target genes selected for this study were: ascorbate peroxidase (APX), glutathione-S-transferase (GST), thioredoxin (TXN), high affi nity potassium transporter protein 1 (HAK1) and salt overly sensitive 1 (SOS1). At an electroconductivity of 14 dS m -1 the primed seeds still germinated to 72%, in contrast with the non-primed seeds which did not germinate. The relative expression of APX was higher in primed seeds and this may have contributed to the maintenance of high germination in primed seeds at high salt concentrations. GST and TXN displayed increased transcript levels in shoots and roots of seedlings from primed seeds. Priming improved seed germination as well as salt tolerance and this is correlated with increased expression of APX in seeds and SOS1, GST and TXN in seedlings.

“…Salt accumulation in soils is one of the most serious global environmental problems. Throughout the semi-arid regions, soil salinization threatens agricultural productivity and food security (De Nys et al, 2005;Hendry and Buckland, 1990;Kotb et al, 2000). Salt accumulation in shallow groundwater systems can be observed in many semi-arid and arid regions.…”
