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 …

Involvement Of Poly(Adp-Ribose)Ylation (Parylation) In The Regulation Of Antioxidant Defense System In Arabidopsis Thaliana Under Salt Stress, Rengi̇n Özgür Uzi̇lday

Turkish Journal of Botany

Posttranslational modifications (PTM) are one of the first responses of plants to environmental stress and involve changing the location and activity of proteins in the cell. Addition of poly(ADP-ribose) (PAR) to proteins, poly(ADP-ribose)ylation (PARylation), is a posttranslational modification resulting from the binding of ADP-ribose from NAD+ to target proteins by PAR polymerases (PARP). PARylation is involved in many physiological events in plants including abiotic and biotic stress response. The aim of this work was to understand involvement of PARylation in inducing enzymatic antioxidant defence and alternative electron sinks in response to salinity.
