Rubisco And Abiotic Stresses In Plants: Current Assessment, Abdulbaki Shehu Abdulbaki, Hameed Alsamadany, Yahya Alzahrani, Bolaji Umar Olayinka
Turkish Journal of Botany
Abiotic stresses are serious environmental factors militating against the production of many crops around the world. The consequence of this, is the difficulty of meeting the demands of the increasing world population. Aside from other negative effects, reduction in photosynthesis is an important feature of abiotic stresses. Abiotic stresses limit photosynthesis in a number of ways. The reduction in ribulose 1, 5-bisphosphate carboxylase/oxygenase (Rubisco) content and activity is one of the paramount ways through which abiotic stresses affect photosynthesis. Rubisco is the CO2 fixing enzyme of photosynthesis and also catalyses the photo-respiratory carbon oxidation. The enzyme has low turnover and …

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 …
