Vasarzaļo rododendru spraudeņu pavairošanas potenciāls atkarībā no mātes augu un spraudeņu apstrādes
2015
Darba mērķis bija noskaidrot vasarzaļo rododendru spraudeņu pavairošanas potenciālu atkarībā no mātes augu priekšapstrādes (etiolācija, steidzināšana) un spraudeņu apstrādes ar auksīnu – indol-3-sviestskābi (ISS). Mātes augu etiolācija kopā ar ISS veicināja straujāku rizoģenēzi, bet neietekmēja apsakņoto spraudeņu skaitu. Etiolācija uzlaboja pārziemošanu grūtāk apsakņojamiem spraudeņiem. Mātes augu steidzināšana kopā ar ISS uzlaboja spraudeņu rizoģenēzi grūtāk apsakņojamiem genotipiem, veicināja jauno dzinumu attīstību, uzlabojot spraudeņu pārziemošanu. Nodrošinot apsakņotajiem spraudeņiem nepārtrauktu veģetācijas periodu, var būtiski palielināt pārziemojušo spraudeņu skaitu. Cietes koncent…
Advances in Wine Fermentation
2021
Fermentation is a well-known natural process that has been used by humanity for thousands of years, with the fundamental purpose of making alcoholic beverages such as wine, and also other non-alcoholic products. From a strictly biochemical point of view, fermentation is a process of central metabolism in which an organism converts a carbohydrate, such as starch or sugar, into an alcohol or an acid. The fermentation process turns grape juice (must) into wine. This is a complex chemical reaction whereby the yeast interacts with the sugars (glucose and fructose) in the must to create ethanol and carbon dioxide. Fermentation processes to produce wines are traditionally carried out with Saccharo…
Characterization of the autoantigen La (SS-B) as a dsRNA unwinding enzyme
1997
During the analysis of the La (SS-B) autoantigen for catalytic activities an ATP-dependent double-stranded RNA unwinding activity was detected. Both native and recombinant La proteins from different species displayed this activity, which could be inhibited by monospecific anti-La antibodies. La protein was able to melt dsRNA substrates with either two 3'-overhangs or a single 3'- and a 5'-overhang. Double-stranded RNAs with two 5'-overhangs were not unwound, indicating that at least one 3'-overhang is required for unwinding. Sequence elements of the La protein that might be involved in dsRNA unwinding, such as an evolutionarily conserved putative ATP-binding motif and an element that is hom…
