Identification of rice blast resistance genes in the rice varieties developed with DNA-markers assistance

open access: yesЗерновое хозяйство России, 2018
Eight rice varieties of the Far East breeding have been studied by the method of DNA-typing to establish the presence of rice blast resistance genes. Six varieties possess one gene each: the varieties ‘Khankaysky 429’ and ‘Khankaysky 52’ possess the gene

Impact of Ca2+-Induced PI(4,5)P2 Clusters on PH-YFP Organization and Protein-Protein Interactions

open access: yesBiomolecules, 2022
Despite its low abundance, phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2) is a key modulator of membrane-associated signaling events in eukaryotic cells. Temporal and spatial regulation of PI(4,5)P2 concentration can achieve localized increases in the

Effect of magnetic frustration on single-hole spectral function in the t-t'-t''-J model

open access: yes, 1998
We examine the effect of the magnetic frustration J' on the single-hole spectral function in the t-t'-t''-J model. At zero temperature, the exact diagonalization (ED) and the self-consistent Born approximation (SCBA) methods are used.
