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

The Trade-Off Between Uvb Sensitivity And Tolerance Against Other Stresses In African Ricespecies, Gideon Sadikiel Mmbando, Jun Hidema
Turkish Journal of Botany
Climate change and ozone depletion have caused increased ultraviolet B (UVB; 280-315nm) radiation levels on earth, which has been predicted to cause decreased growth and yield of various crops, including rice, the most important staple food worldwide. UVB radiation sensitivity varies extensively in Asian rice (Oryza sativa L.) and African rice (Oryza glaberrima Steud. and Oryza barthii A. Chev.) cultivars, and the activity of cyclobutane pyrimidine dimer (CPD) photolyase that repairs UVB-induced CPD is an essential factor underlying UVB sensitivity in rice. Unlike Asian varieties, African rice possesses different origins, and it is cultivated in the African continent under environmental …
