“…Components of the second group have functions in membrane protection, including production of osmoprotectants and antioxidants as well as reactive oxygen species scavengers. All of these processes have been major targets of genetic engineering approaches to produce plants that have enhanced stress tolerance (Valliyodan and Nguyen, 2006;Trujillo et al, 2008;Goel et al, 2010;Quan et al, 2010;Manavalan et al, 2012).…”

Global climate change and a growing population require tackling the reduction in arable land and improving biomass production and seed yield per area under varying conditions. One of these conditions is suboptimal water availability. Here, we review some of the classical approaches to dealing with plant response to drought stress and we evaluate how research on RECEPTOR-LIKE KINASES (RLKs) can contribute to improving plant performance under drought stress. RLKs are considered as key regulators of plant architecture and growth behavior, but they also function in defense and stress responses. The available literature and analyses of available transcript profiling data indeed suggest that RLKs can play an important role in optimizing plant responses to drought stress. In addition, RLK pathways are ideal targets for nontransgenic approaches, such as synthetic molecules, providing a novel strategy to manipulate their activity and supporting translational studies from model species, such as Arabidopsis thaliana, to economically useful crops.

The contribution of Glutathione (Gsh) in drought stress tolerance is an established fact. however, the proteins which are directly or indirectly related to the increased level of Gsh in response to drought stress are yet to be known. To explore this, here, transgenic tobacco plants (NtGp11) overexpressing gamma-glutamylcysteine synthetase (γ-ECS) was tested for tolerance against drought stress. NtGp11 conferred tolerance to drought stress by increased germination rate, water retention, water recovery, chlorophyll, and proline content compared with wild-type plants. semi-quantitative RT-PcR analysis revealed that the transcript levels of stress-responsive genes were higher in NtGp11 compared with wild-type in response to drought stress. Two-dimensional gel electrophoresis (2-De) coupled with MaLDI TOF-TOF Ms/Ms analysis has been used to identify 43 differentially expressed proteins in response to drought in wild-type and NtGp11 plants. The results demonstrated the up-accumulation of 58.1% of proteins among which 36%, 24%, and 20% of them were related to stress and defense, carbon metabolism and energy metabolism categories, respectively. Taken together, our results demonstrated that Gsh plays an important role in combating drought stress in plants by inducing stress related genes and proteins like hsP70, chalcone synthase, glutathione peroxidase, thioredoxin peroxidase, acc oxidase, and heme oxygenase I.

“…against a concentration gradient) across plant cell membranes (plasmalemma and tonoplast) is usually coupled to the proton (H + ) electrochemical potential established by H + -translocating pumps. The vacuolar Na + /H + antiporter and H + -pyrophosphatase pump (H + -PPase) are genotype dependent and confer tolerance to salinity (Goel et al, 2010;Bhaskaran et al, 2011). Additionally, resistant crops benefit from the higher capacity of K + -Na + homeostasis.…”

Understanding how plants respond to salinity, which severely restricts plant growth, productivity, and survival, is highly important in agriculture. Using three genotypes of Matricaria recutita L. (Shiraz, Ahvaz, and Isfahan) with different sensitivity to NaCl, the effect of long-term (about 110 days) NaCl treatments (2.5, 6, 9, and 12 dS * m -1 ) on crop growth, oil quality and quantity, and nutrient variations were investigated to underpin its agricultural management in the future. The adaptation strategy and plant responses were influenced by salinity level, genotype, and genotype × salinity interactions. With higher productivity compared to the Isfahan genotype, the Shiraz and Ahvaz genotypes had efficient Na + exclusion at root surface as an avoidance strategy; however, under higher NaCl concentration, their higher performance were mainly attributed to the Na + sequestration in root vacuoles and higher Ca 2+ /Na + , Mg 2+ /Na + , and root/shoot ratios as tolerance strategies. The higher oil yield and chamazulene percentage in the Isfahan genotype were not affected by salinity level and were only genotype dependent. Under 12 dS*m -1 NaCl, roots of the Shiraz and Ahvaz genotypes accumulated markedly higher Ca 2+ (2.5% and 1.5% respectively) and Mg 2+ (1.6% and 1.3% respectively), required for membrane stability and chlorophyll synthesis, respectively, more than the Isfahan genotype (0.2% Ca and 0.1% Mg 2+ ) and considerably more than the control plants to keep low concentrations of ion toxicity of Na 2+ and Cl -in shoots. Overall, greater salt tolerance found in the Shiraz and Ahvaz genotypes could be due to a variety of mechanisms, including higher efficiency of nutrient uptake (Ca 2+ , Mg 2+ , and Zn 2+ ), utilization (N, P, Ca 2+ , and Mg 2+ ), compartmentation (Na in roots), and maintenance of higher root/shoot ratios. Taking flower and oil yield as well as chamazulene percentage into consideration, the findings recommended cultivation of the Ahvaz genotype in the absence of salt stress (by 1.18 g*plant -1 , 6.25 kg*ha -1 , and 12.54% respectively), the Isfahan genotype under 6 dS*m -1 NaCl (by 0.73 g*plant -1 , 4.84 kg*ha -1 , and 11.66% respectively), and the Shiraz genotype under high salinity of 9 and 12 dS*m -1 NaCl (by 0.68 g*plant -1 , 5.20 kg*ha -1 , and 13.46% respectively under 12 dS*m -1 NaCl).
