Uncontrolled proliferation is the hallmark of cancer and other proliferative disorders and abnormal cell cycle regulation is, therefore, common in these diseases. Cyclin-dependent kinases (CDKs) play a crucial role in the control of the cell cycle and proliferation. These kinases are frequently deregulated in various cancers, viral infections,(More)
Symptoms of general stunting and yellowing of leaves were observed in diseased cultivated strawberry (Fragaria x ananassa Duchesne) in Lithuania. Analysis of 16S rRNA gene sequences amplified by PCR indicated that the symptoms were associated with infection by a phytoplasma, designated strawberry yellows (StrawY) phytoplasma. Phylogenetic analysis of 16S(More)
Phytoplasmas are classified into 16Sr groups and subgroups and 'Candidatus Phytoplasma' species, largely or entirely based on analysis of 16S rRNA gene sequences. Yet, distinctions among closely related 'Ca. Phytoplasma' species and strains based on 16S rRNA genes alone have limitations imposed by the high degree of rRNA nucleotide sequence conservation(More)
Forty-two strains of gram-positive, aerobic, heterotrophic, obligately thermophilic, spore-forming bacteria were isolated from a geothermal site near the Baltic Sea in Lithuania. All of the strains were able to hydrolyze collagen and/or casein. Since characteristics of proteolytic activity are correlated with taxonomic positions of bacteria, the strains(More)
Although mainly known as pathogens that affect angiosperms, phytoplasmas have recently been detected in diseased coniferous plants. In 2008–2014, we observed, in the Curonian Spit of Western Lithuania and in forests of Southern Lithuania (Varena district), diseased trees of Scots pine (Pinus sylvestris) and mountain pine (Pinus mugo) with unusual symptoms(More)
