Uzun et al. (2009) investigated the systematics of Citrus using SRAP markers, utilizing a diverse group of 83 taxa dominated by cultivated species and interspecific hybrids, but representing all tribes and subtribes within the Rutaceae.
To investigate the hydrogen isotope systematics during methanogen growth, the initial δDH2O and δDH2 values in the batch cultures were adjusted by adding D2O and DH molecules (Table 2).
Lee et al. (2007) investigated the trace element systematics in natural Fe O S magmas and proposed that a similar Fe O S melt, which can account for the difference between the 142Nd/144Nd ratios of chondrites and the ASE, had formed during the final stages of magma ocean solidification.
In addition, mt genome sequences have provided useful markers for investigating population genetic structures, systematics and phylogenetics of organisms.
In addition, mt genome sequences have provided useful markers for investigating population genetic structures, systematics and phylogenetics of organisms due to their maternal inheritance, higher mutation rates than nuclear genes and relatively conserved genome structures [ 3- 5].
This study uses a qualitative approach to investigate how students gain representational competence with phylogenetic trees throughout a course on plant systematics.
Mitochondrial and nuclear genes have generally been employed for different purposes in molecular systematics, the former to resolve relationships within recently evolved groups and the latter to investigate phylogenies at a deeper level.
This is the first attempt to monitor both hydrogen and carbon isotope systematics in low-pH2 cultures, although the hydrogen and carbon isotope systematics have been investigated separately (Penning et al. 2005; Yoshioka et al. 2008) (Additional file 1).
In this study, we therefore investigated the hydrogen and carbon isotope systematics of H2O H2 CO2 CH4 during the growth of different hydrogenotrophic methanogens under various growth conditions and the effect of H2 availability.
