Wartości pH wszystkich buforów zależą od temperatury i stężenia. W przypadku buforów Tris pH wzrasta o około 0,03 jednostki na każdy °C spadku temperatury i spada o 0,03-0,05 jednostki na dziesięciokrotne rozcieńczenie. Do precyzyjnych zastosowań należy używać dokładnie skalibrowanego miernika pH z elektrodą szklaną/kalomelową.

Tropical plants have adapted to strong solar ultraviolet (UV) radiation. Here we compare molecular responses of two tropical mangroves Avecennia marina and Rhizophora apiculata to high-dose UV-B. Whole-genome bisulfate sequencing indicates that high UV-B induced comparable hyper- or hypo-methylation in

Virus inoculation is a basic experimental procedure to evaluate the resistance of a rice variety or a transgenic material upon virus infection. We recently demonstrated that Rice ragged stunt virus (RRSV), an oryzavirus that is transmitted by brown planthopper (BPH)
MicroRNAs (miRNAs) play important roles in plant growth, development, and response to infection by microbes. Double-stranded RNA binding protein 1 (DRB1) facilitates the processing of primary miRNA transcripts into mature miRNAs. Recently, we found that NS3 protein encoded by rice
Here, we describe a method that can be used to evaluate the function of predicted signal peptides. This method utilizes the yeast Saccharomyces cerevisiae YTK12 strain and pSUC2 vector in which the pSUC2 vector with fused predicted signal peptide is
The content of biogenic compounds and the biological activities of barley (Hordeum vulgare L.)-grain extracts was evaluated. The sufficiently large and heterogeneous set of barley genotypes (100 accessions) enabled the selection of special genotypes interesting for potential industrial, pharmaceutical, and
