Kinetin and spermine mediated induction of salt tolerance in wheat plants: Leaf area, photosynthesis and chloroplast ultrastructure of flag leaf at ear emergence

Roles of osmoprotectants in improving salinity and drought tolerance in plants: a review

“…in the cell may lead to the drastic changes in different physiological processes and hence decline growth and plant productivity (Kaya et al 2013). Aldesuquy et al (2014) have reported 25 % decrease in leaf area, pigment content, Hill activity and photosynthetic efficiency of wheat plants after irrigation with sea water. Translocation of salts from roots to shoots is the product of transpirational flux, and is prerequisite to maintain water level of plants (Flowers and Yeo 1992).…”

“…The PSII has been considered the major site of salinity stressmediated damage to electron transport chain activity (Mehta et al 2010). Such inhibition in photosynthetic process is also discussed by Aldesuquy et al (2014) terms of reduced leaf area, photosynthetic pigments content, Hill reaction and 14 CO 2 fixation, and altered morphology of chloroplasts, number of reaction centres, net CO 2 assimilation rate and Rubisco activity. Furthermore, study showed that salinity stress declined biomass accumulation in eggplant due to down regulation of photosynthetic gas exchange rate, net photosynthetic rate, transpiration rate, stomatal conductance, water utilization efficiency, quantum efficiency of PSII photochemistry and photochemical quenching, and up regulation of non-photochemical quenching (Wu et al 2012).…”

Impact of Seawater Salinity on Ultrastructure of Chloroplasts and Oleosomes in Relation to Fat Metabolism in Flag Leaf of Two Wheat Cultivars During Grain-filling

“…A computerized method was followed to count chloroplasts in semi-thin sections as those described by Aldesuquy and et al [16].…”

“…A new technique developed using the image analysis for measuring the volume of oleosomes (in semi-thin sections from flag leaf mesophyll tissues was estimated to a leaf or cell unit volume for each treatment) was performed using the methods adopted by Aldesuquy et al [16].…”

Efficient regeneration and Agrobacterium-mediated transformation protocol for recalcitrant indica rice (Oryza sativa L.).

“…In particular, KIN produced shoots with 2 to 3 fold higher in chlorophyll content than BAP and TDZ as shown in this study. The ability of KIN to regulate the development and maintenance of chloroplasts and photosynthetic organelles has improved the overall plant vigour and stress resistance (Alsokari, 2009;Aldesuquy et al, 2014). Jamei et al (2008) further elaborated that the activity of the 5-aminolevulinic acid dehydratase (ALA-D) was increased when KIN was applied exogenously to maize seedlings.…”
