| 4 | Biochemical Mechanism Unlocking Their Potential Role in Salt Tolerance Mechanism of Zizyphus Germplasm显示文摘Salinity is one of the major constraints reducing plant growth and yield.Irrigation with poor quality and brackish water to orchards is a major cause of stunted growth and low yield.The salt tolerance mechanism is one of the complicated genomic characters that is very problematic to develop in fruit trees and becomes much more severe at any growth and developmental stage.Osmotic stress and hormonal imbalances are major constraints causing low biomass production.Fruit tree tolerance/sensitivity is chiefly based on the activation of a defense system comprised of super-oxidase dismutase(SOD),peroxidase(POD)and catalases(CAT),non-enzymatic compounds including ascorbic acid,phenolics,flavonoids,stress indicators[i.e.,hydrogen peroxide(H2O2),lipid peroxidation,malondialdehyde(MDA),reactive oxygen species(ROS)and osmolytes containing proline,glycine-betaine(GB),ascorbates(APX),glutathione peroxidase(GPX)and glutathione reductase(GR)].Tolerant genotypes must have higher antioxidant assays to cope with the adverse effects of salinity stress because their defense system had the potential to scavenge toxic ROS and protect from membrane leakage.Some work is conducted on agronomic and horticultural crops;however,underutilized fruit crops are still neglected and need serious consideration from plant researchers.Minor fruit crops especially Zizyphus had excellent nutritional aspects.The current study provides detailed insights into the physiological and biochemical mechanisms of Zizyphus species to cope with the adverse effects of salinity by improving their plant defense system.The development of salt-tolerant germplasm is a requisite and can be developed by utilization of physiological,biochemical,and molecular mechanisms.Application of different molecular approaches(i.e.,genome mapping,genome editing,genetic transformation,proteomics,transcriptomics,and metabolites)are effective for higher yield by improving tolerance mechanisms. | Riaz Ahmad Hafiza Muniba Din Muhammad Safina Naz Meryam Manzoor Muhammad Ahsan Altaf | 2023 | Phyton-International Journal of Experimental Botany2023，92，5： | 0 |
| 5 | Influence of the Inclination Angle on Mixed Convection and Heat Transfer in a“T”Shaped Double Enclosure显示文摘The effect of the tilt angle on mixed convection and related heat transfer in a“T”shaped double enclosure with four heated obstacles on the bottom surface is numerically investigated.The considered obstacles are constantly kept at a relatively high(fixed)temperature,while the cavity’s upper wall is cooled.The finite volume approach is used to solve the mass,momentum,and energy equations with the SIMPLEC algorithm being exploited to deal with the pressure-velocity coupling.Emphasis is put on the influence of the tilt angle on the solution symmetry,flow structure,and heat exchange through the walls.The following parameters and related ranges are considered:Rayleigh number 104≤Ra≤5.105,tilt angle 0°≤φ≤90°,Reynolds number 100≤Re≤1000,Prandtl number Pr=0.72,block height B=0.5,opening width C=0.15,and distance between blocks D=0.5.The results reveal different branches of solutions on varying Re andφ.They also show that the symmetry of the solution regarding the P_(2)axis is retained for all cases with no tilt and for values of Re between 100 and 1000. | M’Barka Mourabit Meryam Meknassi Soukaina Fekkar Soumia Mordane Hicham Rouijaa El Alami Semma | 2023 | Fluid Dynamics & Materials Processing2023，19，7： | 0 |
