Biology definition:Pioneer speciesis the first ones to colonize a bare substrate in primary succession while first to colonize a destroyed habitat in secondary succession.Examples:(1) a pioneer species of lyme grass (Leymus arenarius) on a barren land of sand, (2) pioneer species ofplants(e.g...
species will be used to replace the original pioneer species. legco.gov.hk 局長剛才 也提到會用本土樹木取代原本的先鋒 樹木 的。 legco.gov.hk [...] 700 participating children would be admitted to the first batch of seven pioneer projects, and the number could be increased in the second...
1a). Finally, we found that the Lola-I motifs in these promoters often showed specific conservation across Drosophila species, which is indicative of their functional importance (Supplementary Fig. 1a, b). To test whether Lola-I is the factor responsible for causing these promoters to change ...
We present a simple mathematical model for the dynamics of a successional pioneer–climax system using difference equations. Each population is subject to inter- and intraspecific competition; population growth is dependent on the combined densities of both species. Nine different geometric cases, corresp...
Of course, we cannot turn back [the clock] on the loss of species. That’s a finite, terminal loss, which is really damaging. But [for the] functions of ecosystems, it’s not too late to now turn back and move towards a safe space and build resilience into both food systems and ec...
Here we have determined high-resolution structures of three FoxH1 proteins (from human, frog and fish species) and four DNAs to clarify the way in which FoxH1 binds to these sites. We found that the protein-DNA interactions extend to both the minor and major DNA grooves and are thus ...
The utility of maize variety X6H867 also extends to crosses with other species. Commonly, suitable species will be of the family Graminaceae, and especially of the genera Zea, Tripsacum, Coix, Schlerachne, Polytoca, Chionachne, and Trilobachne, of the tribe Maydeae. Potentially suitable ...
Any DNA sequences, whether from a different species or from the same species, which are inserted into the genome using transformation are referred to herein collectively as “transgenes”. Over the last fifteen to twenty years several methods for producing transgenic plants have been developed, ...
Any DNA sequences, whether from a different species or from the same species, which are stably inserted into the cell using transformation are referred to herein collectively as “transgenes” and/or “transgenic events”. In some embodiments of the invention, a transformed variant of X13C764 ...
A breeder will commonly work to combine a specific trait of an undeveloped variety of the species, such as a high level of resistance to a particular disease, with one or more of the elite agronomic characteristics (yield, maturity, plant size, lodging resistance, etc.) needed for use as ...
