Figure 2.Differential RNA stability distinguishes between regulatory elements. Transcription initiation at gene-distal enhancers(A)and gene promoters(B)results in characteristically different RNAs. Enhancer-templated noncoding RNAs (eRNAs) are typically short, nonspliced, and degraded by the nuclear exosome...
50). For example, the models account for equilibrium states, but it has been recognized since the 1980s that plant species are unlikely to relocate as fast as their appropriate climate envelopes (for example, ref. 51). Also, models of treeline movement overestimate latitudinal relocation by up...
we assess how ecologists have selected, used, and evaluated the performance of the indicator species. We reviewed all articles published inEcological Indicators(EI) between January 2001 and December 2014, focusing on the number of indicators used (one or more); common taxa employed; terminology, ...
7b). We also noted that VEX2-depleted cells displayed greater derepression of VSGs in expression sites containing two Pol-I promoters, while ‘metacyclic VSGs’ (VSGs typically activated in the insect to mammal transmission stage metacyclic cells30) in monocistronic expression sites, were only ...
Ecosystems are brimming with myriad compounds, including some at very low concentrations that are indispensable for insect survival and reproduction. Screening strategies for identifying active compounds are typically based on bioassay-guided approaches.
Tall fescue (Festuca arundinacea Schreb.) is major cool-season forage and turf grass species worldwide, but high-temperature is a major environmental stress that dramatically threaten forage production and turf management of tall fescue. However, very little is known about the whole-genome molecular...
As it becomes increasingly possible to obtain DNA sequences of orthologous genes from diverse sets of taxa, species trees are frequently being inferred from multilocus data. However, the behavior of many methods for performing this inference has remained
The high sensitivity of this genus to N deposition is consistent with the hypothesis that EcMF with peroxidases are selected against under higher N conditions. Cortinarius species vary somewhat in their sensitivity to N deposition, but whether this relates to peroxidase copy number or activity is ...
(short-beaked echidna) as its only species, has a distribution across much of Australasia, found wherever its primary prey, ants andtermites, are abundant. Introduction of the dingo 10,000 years ago probably has reduced the range of Tachyglossus, much as it has been thought to have a ...
