Article
Photosynthesis and yield traits in different soybean lines in response to salt stress
To evaluate utility of different salt-tolerant lines, three soybean lines with different resistance to salt were planted in the field under control and salt-stress conditions for two years. The results showed ...

Sodium bisulfite enhances photosynthesis in rice by inducing Rubisco activase gene expression
To investigate how bisulfite promotes photosynthesis, a pot experiment was conducted with rice (Oryza sativa L.) plants to determine Rubisco activity and content, and Rubisco activase (RCA) gene expression after ...

Article
The B subfamily of plant ATP binding cassette transporters and their roles in auxin transport
The ATP binding cassette B/multidrug-resistance/P-glycoprotein (ABCB/MDR/PGP) subfamily is a member of the ABC protein family. Significant progress has been made in the functional characterization of ABCB genes, ...

Article
Relationship between Rubisco activase isoform levels and photosynthetic rate in different leaf positions of rice plant
To investigate into the relationship between two Rubisco activase (RCA) isoforms and photosynthetic rate, a set of enzyme-linked immunosorbent assay (ELISA) were developed for accurate quantification of two RC...

Article
Photosynthetic response of salt-tolerant and sensitive soybean varieties
The physiological response of two soybean varieties to salt stress was examined. The results showed that salt stress induced a significantly (p<0.01) lower decrease of the net photosynthetic rate (P ...

Characterization of Cadmium Uptake and Translocation in a Cadmium-Sensitive Mutant of Rice (Oryza sativa L. ssp. japonica)
To understand the physiological mechanism that confers Cd sensitivity/tolerance, Cd uptake and translocation by Cd-sensitive mutant and wild-type rice seedlings were characterized using radioactive tracer. Tim...

Low concentration of bisulfite enhances photosynthesis in tea tree by promoting carboxylation efficiency in leaves
Tea tree (Melaleuca alternifolia) canopy was sprayed with low concentration of NaHSO3 or mixture of NaHSO3+ KH2PO4. The treatments significantly enhanced net photosynthetic rate (P N), car...

Article
Up-regulation of cyclic electron flow and down-regulation of linear electron flow in antisense-rca mutant rice
To investigate how excess excitation energy is dissipated in a ribulose-1,5-bisphospate carboxylase/oxygenase activase antisense transgenic rice with net photosynthetic rate (P N) half of ...

Article
Effect of Cd on growth, photosynthetic gas exchange, and chlorophyll fluorescence of wild and Cd-sensitive mutant rice
Growth, photosynthetic gas exchange, and chlorophyll fluorescence characteristics were investigated in wild type (WT) and Cd-sensitive mutant rice (Oryza sativa L.) plants using 50 µM Cd treatment for 12 d follow...

Article
Induction of cyclic electron flow around photosystem 1 and state transition are correlated with salt tolerance in soybean
We investigated the role of cyclic electron flow around photosystem 1 (CEF1) and state transition (ST) in two soybean cultivars that differed in salt tolerance. The CEF1 and maximum photochemical efficiency (Fv/F

Article
Root morphology and cadmium uptake kinetics of the cadmium-sensitive rice mutant
To understand the physiological mechanism that confers Cd sensitivity, root morphology and Cd uptake kinetics of the Cd-sensitive mutant and wild type rice were investigated. The root length, root surface area...

Cyclic electron flow around photosystem 1 is required for adaptation to salt stress in wild soybean species Glycine cyrtoloba ACC547
A wild soybean species Glycine cyrtoloba ACC547 was found to possess a high salinity resistance trait. It maintained higher net photosynthetic rate (PN) and maximal photochemical efficiency (Fv/Fm) than the soybe...

Leaf anatomy, chloroplast ultrastructure, and cellular localisation of ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBPCO) and RuBPCO activase in Amaranthus tricolor L.
In Amaranthus tricolor the leaf structure included three layers of chlorenchyma on the vascular bundle periphery, namely, mesophyll cells (MSCs) with few chloroplasts, outer larger round bundle sheath cells (BSCs...

Effects of Nitrogen Deficiency on Gas Exchange, Chlorophyll Fluorescence, and Antioxidant Enzymes in Leaves of Rice Plants
Gas exchange, chlorophyll (Chl) fluorescence, and contents of photosynthetic pigments, soluble proteins (ribulose-1,5-bisphosphate carboxylase/oxygenase, RuBPCO), and antioxidant enzymes were characterized in ...
