Synergism And Antagonism In Plant Acclimation To Abiotic Stress Combinations, Karl-Josef Dietz Jan 2021

Synergism And Antagonism In Plant Acclimation To Abiotic Stress Combinations, Karl-Josef Dietz

Turkish Journal of Botany

Acclimation of plants to their environment involves mechanisms at all molecular levels and only the complete temporal and spatial pattern adequately describes the acclimation state. The diversity of physiological states realized in plants increases by the essentially infinite combinations of abiotic and biotic stresses, considering duration, impact order, and strength. The interference between stressors involves phenomena of synergism, antagonism, and indifference. This review exemplarily sketches principles of interference considering posttranslational modifications, the formation of molecular assemblies in regulosomes, the regulation of gene expression, and the vast number of other posttranscriptional controls e.g., in RNA processing and recruitment to ribosomes. Small …


Mirnas Involved In Drought Stress In Italian Ryegrass (Lolium Multiflorum L.), Gürkan Demi̇rkol Jan 2021

Mirnas Involved In Drought Stress In Italian Ryegrass (Lolium Multiflorum L.), Gürkan Demi̇rkol

Turkish Journal of Botany

miRNAs have been characterized as a regulator of main processes in plants by silencing genes. The functions of microRNAs have been studied in various crops, hovewer, no studies have been observed about miRNAs in Italian rygrass (Lolium multiflorum L.) against drought stress. This experiment aimed to reveal the involvement of miRNAs against drought stress in sensitive and tolerant Italian ryegrass genotypes. Four genotypes (G1 and G2 as drought sensitive - G3 and G4 as drought tolerant) were selected. The sensitivities of these genotypes against drought stress were verified by performing growth parameters, relative water and proline contents under normal and …
