Metabolic and molecular events occurring during chromoplast biogenesis [PDF]
, 2011 Chromoplasts are nonphotosynthetic plastids that accumulate carotenoids. They derive from other plastid forms, mostly chloroplasts. The biochemical events responsible for the interconversion of one plastid form into another are poorly documented. However,

Effect of salicylic acid pretreatment on cadmium toxicity in wheat
Biologia Plantarum, 2010 Cadmium (100, 400 and 1000 μM CdCl2) treatments resulted in the inhibition of root dry biomass, root elongation and increased Cd accumulation in wheat (Triticum aestivum L.) roots.

Effects of OsRCA Overexpression on Rubisco Activation State and Photosynthesis in Maize
Plants, 2023 Ribulose–1,5–bisphosphate carboxylase/oxygenase (Rubisco) is the rate–limiting enzyme for photosynthesis. Rubisco activase (RCA) can regulate the Rubisco activation state, influencing Rubisco activity and photosynthetic rate. We obtained transgenic maize

Continuous artificial synthesis of glucose precursor using enzyme-immobilized microfluidic reactors
Nature Communications, 2019 Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) is a difficult enzyme to work with. Here, the authors covalently immobilized it in a microfluidic reactor to enhance its storage/thermal stabilities and reusability, which enabled the continuous ...

Low Salinity Improves Photosynthetic Performance in Panicum antidotale Under Drought Stress
Frontiers in Plant Science, 2020 Salinity and drought are two often simultaneously occurring abiotic stresses that limit the production of food crops worldwide. This study aimed to distinguish between the separate and combined impacts of drought and salinity on the plant response ...

Competition of Pyridoxal 5'-Phosphate with Ribulose 1,5-Bisphosphate and Effector Sugar Phosphates at the Reaction Centers of the Spinach Ribulose 1,5-Bisphosphate Carboxylase/Oxygenase [PDF]
, 1980 The Stimulation of the carboxylase reaction by effectors of ribulose 1,5-bisphosphate carboxyl ase/oxygenase displays higher sensitivity towards pyridoxal 5'-phosphate inhibition than the catalytical process itself. Pyridoxal 5'-phosphate binding to the

Photorespiration-Induced Reduction of Ribulose Bisphosphate Carboxylase Activation Level [PDF]
Plant Physiology, 1985 Leaf photosynthesis and ribulose bisphosphate carboxylase activation level were inhibited in several mutants of the C(3) crucifer Arabidopsis thaliana which possess lesions in the photorespiratory pathway. This inhibition occurred when leaves were illuminated under a photorespiratory atmosphere (50% O(2), 350 microliters per liter CO(2), balance N(2)),

Storage and Maintaining Activity of Ribulose Bisphosphate Carboxylase/Oxygenase [PDF]
Plant Physiology, 1981 Purified ribulose-1,5-bisphosphate carboxylase/oxygenase in 50% saturated (NH(4))(2)SO(4) was stable when frozen as small beads in liquid nitrogen and stored at -80 C. When stored as a slurry at 4 C most of the activity was lost within four weeks. This loss was due not only to enzyme polymerization.
