“…The apparent decrease in F v /F m values observed in rice plants subjected to severe drought stress is consistent with the results of a previous study (Souza et al 2004). Moreover, the reduction of area above the fluorescence curve and Fm was similar to the response of Bruguiera cylindrica (L.) Blume under salt stress (Palliyath and Puthur 2018). In wheat, the high-yielding varieties under drought stress were shown to have higher Fm, Fv/Fm, and Fv (Paknejad et al 2007) and Chl fluorescence can be used to determine drought tolerance in barley (Li et al 2006).…”

This research aims to evaluate the photosynthesis-related parameters in rice chromosome segment substitution lines (CSSL), containing drought-tolerant region from DH212 in a Khao Dawk Mali105 genetic background. Screening at seedling stage indicated that CSSL4 was more tolerant to drought stress than KDML105 with the higher maximal quantum yield of PSII photochemistry. After withholding water, the decline in light-saturated net photosynthetic rate due to drought stress occurred simultaneously with the decrease in electron transport rate and effective quantum yield of PSII photochemistry values, suggesting that stomatal changes affect light-saturated net photosynthetic rate (PNmax) during the initial drought response. KDML105 rice showed the highest level of electron transport rate/PNmax ratio. This suggested that KDML105 h a s the lowest ability to use reducing power in photosynthesis process under drought stress conditions. Loci containing single nucleotide polymorphisms between CSSL4 and KDML105 were subjected for co-expression network analysis with 0.99 correlation. The co-expression between calmodulin-stimulated calcium-ATPase and C2H2 zinc finger protein was detected. This locus may contribute to the maintenance ability of photosynthesis process under drought stress conditions.

“…Ascorbate peroxidase activity also increased with increasing salinity up to optimal concentration of 300 mM NaCl. Similar report on increased the ascorbate peroxidase activity was increased with increasing concentration of NaCl up to the optimum level in Bruguiera cylindrica (Sruthi & Puthur, 2018). Hydrogen peroxide is reduced to water by APX and plays a role in cell defense mechanism (Ashraf, 2009).…”

“…SOD is an essential antioxidant enzyme with the capacity to restore oxidation damage caused by Reactive Oxygen Species, and it maintaining normal physiological functions and coping with oxidative stress in the regulation of intracellular levels of ROS (Foyer and Noctor, 2003). Sruthi and Puthur (2018) reported that in Bruguiera cylindrica, the SOD activity was enhanced progressively with increasing salt concentration up to 600 mM NaCl as compared to control. The increase in SOD activity in response to salt stress can be considered as a defense mechanism for scavenging ROS ultimately leading to salt tolerance.…”

“…Therefore, the antioxidant defence system of plants has been attracting considerable interest of the scientific community (Dumont & Rivoal, 2019). A correlation between the antioxidant capacity and NaCl tolerance has been demonstrated in numerous plant species such as Aegiceras corniculatum (Mohanty et al, 2013), Avicennia marina (Maqtari & Nagi, 2014) and Bruguiera cylindrica (Sruthi & Puthur, 2018).…”

The effect of NaCl stress on antioxidant enzymes activities was investigated in the leaves of Excoecaria agallocha. Plants were subjected to different levels of NaCl. 100 to 1000 mM. Above 500 mM these mangrove seedlings did not survive. The leaves of 60 day old plants were used for the analysis of enzyme activities. Parameters of enzymatic and non enzymatic antioxidants such as catalase (CAT), peroxidase (POD), ascorbate peroxidase (APX), polyphenol oxidase (PPO), superoxide dismutase (SOD), ascorbic acid (ASA) and alpha tocopherol were determined. The highest CAT, POD, APX, PPO and SOD activities in the leaf and root enhanced gradually up to 300 mM of NaCl, the highest ASA and tocopherol activities in the leaf and root were observed at 500 mM of NaCl. These data suggest that the capacity to limit oxidative damage is important for the salt tolerance of E. agallocha.
