AFLP from two contrasting habitat types
We get these data from AFLP. In our study, we compare the genetic diversity and differentiation between two contrasting habitat types of Betula ermanii. Our results indicated that the two different type show different genetic structure. We presume that this species evolve under natural selection
MSAP data get from Betula ermanii
We get these data from AFLP. In our study, we compare the epigenetic diversity and differentiation between two contrasting habitat types of Betula ermanii. Our results indicated that the two different type show different epigenetic structure. We presume that this species evolve under natural selection
Peculiarities of Ethylene Polymerization Kinetics with an Imido-Vanadium/Silyl-Chromate Bimetallic Catalyst: Effect of Polymerization Conditions
The
effects of various polymerization conditions such as cocatalyst
concentration, pressure, temperature, and reaction time on ethylene
homopolymerization over a SiO<sub>2</sub>-supported imido-vanadium/silyl-chromate
(Cr-iV) bimetallic catalyst were systematically investigated. The
monometallic silyl-chromate (S-2) and imido-vanadium (iV) catalyst
were also employed for comparison. It was found that the S-2 catalyst
produced a polymer with relatively low molecular weight, while the
iV catalyst produced ultrahigh-molecular-weight polyethylene (UHMWPE).
The bimetallic catalyst was capable of producing reactor blends, with
bimodal molecular weight distribution (MWD) and a considerable amount
of UHMWPE. Increasing cocatalyst concentration and decreasing polymerization
temperature both enhanced the high molecular weight part of the bimodal
MWD while the position of the two peaks remained unchanged. The polymerization
rates all showed first-order dependences with respect to ethylene
pressure for the three catalysts. Ethylene pressure variations caused
no changes in the MWD of polymers made by the three catalysts, indicating
that transfer to the monomer is the main chain transfer mechanism

DataSheet_1_Contrasting patterns of genetic and phenotypic divergence of two sympatric congeners, Phragmites australis and P. hirsuta, in heterogeneous habitats.docx
Habitat heterogeneity leads to genome-wide differentiation and morphological and ecological differentiation, which will progress along the speciation continuum, eventually leading to speciation. Phragmites hirsuta and Phragmites australis are sympatric congeners that coexist in saline-alkaline meadow soil (SAS) and sandy soil (SS) habitats of the Songnen Meadow. The results provided genetic evidence for two separate species of reeds. Genetic diversity and spatial genetic structure supported the specialist-generalist variation hypothesis (SGVH) in these two sympatric reed species, suggesting that P. australis is a generalist and P. hirsuta is a habitat specialist. When we compared these different species with respect to phenotypic and genetic variation patterns in different habitats, we found that the phenotypic differentiation of P. australis between the two habitats was higher than that of P. hirsuta. Multiple subtle differences in morphology, genetic background, and habitat use collectively contribute to ecological success for similar congeners. This study provided evidence of the two reed congeners, which should contribute to their success in harsh environments.</p
Additional file 4: of A newly formed hexaploid wheat exhibits immediate higher tolerance to nitrogen-deficiency than its parental lines
Figure S4. Effects of low N condition on the chlorophyll and carotenoid contents of synthetic hexaploid wheats (BBAADD genome), diploid wheat (DD genome) and tetraploid wheats (BBAA genome). Diploid wheat:TQ18; newly formed (synthetic) hexaploid wheats: AT5, Allo-960 and ELI 13; tetraploid wheats: 37A, ALTAR81, black bird, BOT and TTR04. The seedlings were subjected to low N condition (0.1 mM) for 31 days. The values are means of three biological replicates. Asterisks indicated significant difference (t test, P < 0.05) between control and low N-stressed plants for a given genotype. (TIF 1779 kb
