“…The significant decrease in the rate of photosynthesis was observed in both progressive mild and severe stress. (Chaves et al, 2003;2009 andGrassi andMagnani, 2005). Similar results were reported by Kataria and Singh (2013).…”

“…These compounds can thus neutralize the toxic capacity of the peroxide, superoxide and the hydroxyl radicals present in the tissues [90]. In our studies, we observed a signiicant increase in peroxidase (PO) and catalase (CAT) activities under water deiciency in young seedlings of all tested alfalfa genotypes [15].…”

Alfalfa (Medicago sativa L.) is one of the most cultivated forage legumes in Morocco thanks to its great adaptation to the climatic conditions of this country, its high protein content and its ability to ix atmospheric nitrogen in symbiosis with rhizobia. Environmental stresses such as drought and salinity constitute a major factor limiting the symbiotic nitrogen ixation and legume productivity. In the last decades, this process has interested scholars in understanding the implication of these strains in legume stress tolerance in order to make these symbioses more eicient under diicult conditions. Seed osmopriming is a great technique in the amelioration of seed germination and seedlings growth in responses to several abiotic stress conditions. In this chapter, the efects of water deicit on the Moroccan alfalfa populations and their symbiotic association with rhizobia were discussed. Besides, osmopriming could make these symbioses more eicient especially under stress conditions.

“…16 Oxidative stress is generally generated from the production and accumulation of ROS. 32 • OH is the most reactive species among the ROS and will immediately react with surrounding target molecules after generation. The elevated • OH levels in maize exposed to HBCDs indicated that all three HBCD diastereoisomers induced oxidative destruction to maize, and α-HBCD appeared to be more toxic than the other two diastereoisomers.…”

Hexabromocyclododecane (HBCD), a brominated flame retardant, has become a ubiquitous contaminant due to its wide application, persistence, and toxicity. HBCD diastereoisomers have different physical and chemical properties and may differ in their bioaccumulation and toxicity in plants. Accumulation and toxicity of α-, β-, and γ-HBCDs in maize were investigated in the present study. The accumulation was in the order β-HBCD > α-HBCD > γ-HBCD in roots and β-HBCD > γ-HBCD > α-HBCD in shoots. Both the inhibitory effect of the diastereoisomers on the early development of maize and the intensities of hydroxyl radical and histone H2AX phosphorylation in maize exposed to 2 μg L −1 HBCD followed the order α-HBCD > β-HBCD > γ-HBCD, indicating the diastereomer-specific oxidative stress and DNA damage in maize. It was further confirmed that the generation of reactive oxygen species was one, but not the only, mechanism for DNA damage in maize exposed to HBCDs.
