    2021-6-5 · Changes in protein expression were evaluated using 2D polyacrylamide gels followed by LCMS/MS. DNA methylation was measured using 6,800 element CpG island microarrays. Treatment of cells with CGC-11093 at concentrations ranging from 0.1 to 10 microM caused inhibition of cell growth and metabolic activity, but only minimally affected cell viability.

    2017-3-1 · 2. Results and discussion. Using whole rosettes from Arabidopsis circadian clock mutants lhycca1, prr7prr9, gi and toc1, we analysed, in parallel, mutant-induced changes in transcript and protein abundance before day–night transitions: 1 h (h) before ED and EN.The four mutants have well-defined impacts on the circadian clock. Therefore, by examining growing …

    2019-2-7 · The PacBio data however failed to improve the assembly quality significantly, presumably due to low coverage. Our final draft genome assembly has 2,066,288 sequences with N 50 of 955 (Table 1), indicating significant fragmentation. The estimated size of the single-copy proportion of the genome is 140–160 mb and the estimated size of the whole ...
