Effect of different Bradyrhizobium japonicum inoculants on physiological and agronomic traits of soybean (Glycine max (L.) Merr.) associated with different expression of nodulation genes.

The aim of this work was to check the effects of five Bradyrhizobium japonicum inoculants from different producers on growth, photochemical efficiency, nitrate reductase activity, amount of hydrogen peroxide, activity of catalase, non-specific peroxidase, and superoxide dismutase, seed yield, and nodulation of soybean cv. 'Malaga'. We also evaluated expression of such nodulation genes as NIC1, NOD21, and NORKb.

Two-Dimensional Gel Electrophoresis in Studies of Flower and Leaf Proteome of Common Buckwheat.

Two-dimensional gel electrophoresis (2-DE) is a proteomic tool used for the separation of protein mixtures according to protein isoelectric point and molecular mass. Although gel-free quantitative and qualitative proteomic study techniques are now available, 2-DE remains a useful analytical tool. The presented protocol was performed to analyze the flower and leaf proteome of common buckwheat using 24 cm immobilized pH gradient strips (pH 4-7) and visualization of proteins on gels via colloidal Coomassie G-250 staining.

Phenol-Based Protein Extraction Method for Plant Proteomic Studies.

The protein extraction method based on the phenol solution and combined with protein precipitation with ammonium acetate in methanol and purification in the same solution, and additionally in acetone and ethanol, is recommended for proteomic studies of plant tissues. The obtained protein samples do not require additional nucleic acid digestion and removal of interfering contaminations. The presented protocol was used to analyze the proteome of common buckwheat flowers and leaves.

Climate Change-The Rise of Climate-Resilient Crops.

Climate change disrupts food production in many regions of the world. The accompanying extreme weather events, such as droughts, floods, heat waves, and cold snaps, pose threats to crops. The concentration of carbon dioxide also increases in the atmosphere.

Quantification of Circulating Cell-Free DNA in Idiopathic Parkinson's Disease Patients.

Parkinson's disease (PD) is one of the most common neurodegenerative disorders globally and leads to an excessive loss of dopaminergic neurons in the substantia nigra of the brain. Circulating cell-free DNA (ccf-DNA) are double-stranded DNA fragments of different sizes and origins that are released into the serum and cerebrospinal fluid (CSF) due to cell death (i.e.
