  Kentucky coffeetree - Wikipedia, the free encyclopedia
This tree is found in floodplains and river valleys but is also sometimes seen on rocky hillsides and limestone woods.
This tree is botherd little by heat, cold, drought, inscects, disease, road salt, ice, and alkaline soil.
It forms large clonal colonies, reproducing by shoots sprouting from roots.

 Age-associated changes in the stimulatory effect of transforming growth factor beta on human osteogenic colony ...   (Site not responding. Last check: 2007-10-14)
In the present study, we examined whether aging affects the capacity of transforming growth factor beta (TGF-beta) to stimulate the colony formation of human osteoprogenitor cells.
Outgrowths of bone cells from 98 iliac crest biopsies were plated at a density of 25 cells/cm2 and cultured for 3 weeks in the presence of 10% fetal calf serum.
These data raise the possibility that aging may be associated with a declining capacity of TGF-beta to enlarge the pool of bone cells that can be generated from a single human osteoblast progenitor cell.

 Canada Gardens! - Pollination Ecology of Isotria medeoloides
In Canada, one colony consisting of five individuals was located in 1977 in southern Ontario, but the plants failed to reappear in the spring of 1983 (Stewart 1983).
This relative is somewhat less rare and is found in larger clonal colonies.
Colonies of plants thriving in disturbances are expected to be transient as the environment progresses from seral stage to the next.

 Japanese Honeysuckle - Encyclopedia.WorldSearch   (Site not responding. Last check: 2007-10-14)
Japanese Honeysuckle is considered an invasive exotic weed in the United States, and is classified as a noxious weed by the state of Illinois and New Zealand.
It has done severe damage to eastern American woodlands, often forming vast clonal colonies on forest floors that displace virtually all native ground plants, and climbing into trees and shrubs and severely weakening and even killing them by cutting off sap flow and shading their leaves.
Nonetheless, this species is still sold by American nurseries, often as the cultivar 'Hall's Prolific'.

 Osmunda - Open Encyclopedia   (Site not responding. Last check: 2007-10-14)
The genus Osmunda is a group of primarily temperate-zone ferns.
One of these, the cinnamon fern, Osmunda cinnamomea, forms huge clonal colonies in swamp areas.
These ferns form massive rootstocks with densely-matted, wiry roots.

 Palomar Mountain Fungus (Addendum-1)
The aspen clone is connected by a common root system, and has literally climbed over mountains and across meadows.
Any discussion of massive clonal colonies should also include the conjoined polyps of coral reefs.
However, the question still remains: Do these clonal colonies qualify as a single individual, as in the 1200 ton General Sherman tree of California's Sequoia National Park?

 The Living Desert - Desert Agave
Many agaves, especially those in drier areas, do not place the fate and future of their species on one roll of the dice.
They are able to sustain themselves vegetatively by forming clonal colonies of offsets or ‘pups’.
This greatly increases the odds of passing on their genes because each offset will get a chance to bloom.

I could write you the redox equations for all of those colonies, the change in standard free energy, the ATPs hydrolysed, the bizarre thermicities of some microbial communities, and it would not matter.
All I did was put some paper towels and mud into a jar and leave it in the windowsill.
Their jar holds a stable community, a dynamic equilbrium of life unaware of its confinement, a clonal colony of clonal colonies from a pond across town.

The tuberoids can either replace themselves each year, with the new tuberoids being generated next to or in the same cavity as the ones which are supporting the current plants, or they can increase massively in number, by forming many tubers each season on the ends of roots called "droppers".

Thereby, those colonies bearing the cDNA of interest are found and isolated, the cDNA harvested and subject to sequencing.
The DNA oligomer probes for the unknown gene used for colony selection are synthesized to hybridize, preferably, only with the cDNA for the gene of interest.
Creation of these libraries is time consuming, costly, and introduces bias into the process, as it requires the cDNA in the vector to be transformed into bacteria, the bacteria arrayed as clonal colonies, and finally the growth of the individual transformed colonies.

 Ohio Trees, Bulletin 700-00, Populus – Poplar
The tree reproduces readily from root suckers and may form clonal colonies of great size and age.
Old clones have old-age problems, and the size of the clonal patches reduces cross pollination, further reducing biodiversity.
The young branchlets are reddish-brown and shiny but turn gray and become roughened after the first year.

The clonal thickets reproduce vegetatively by root suckering and have been estimated to be at least 43,000 years old.
These are not clonal populations, they are the actual trees that lived during the time of Christ.
For thousands of years these enormous clonal populations have been spreading across meadows and mountain slopes, and many of the trees actually share a common root system.

Multistage carcinogenesis models have occupied a central position in modeling the carcinogenesis process and formalize the hypothesis that cells have to undergo several transformations from normal cells to overt carcinoma.
An expansion of the CSM allowing for variability between deterministic growth behaviour of phenotypically different colonies was formulated (modCSM) and succesfully applied to focal lesion data of a rat hepatocarcinogenesis experiment (34).
We used a two-stage mutational model with clonal expansion of intermediate cells to mimic the observed J-shaped dose response for cell division in the forestomach of rats treated with caffeic acid.

There are several such “clonal microspecies” in the Tucson area alone, some of which are restricted to a patch of just a few acres (hectares).
More commonly whole fruits fall to the ground or are transported by animals that eat them and, like the joints, sprout new clonal plants from the fleshy rinds.
In contrast to teddy bear cholla’s preference for rocky habitat, jumping cholla grows better on the finer soils of lower bajadas and valleys.

This peculiar characteristic, coupled with the fact that the large leaves mean few twigs in the winter profile, make it a tree that is ideal for urban shading where winter sunlight is to be maximized (such as in proximity to solar hot-air systems).
The coffeetree forms large clonal colonies, reproducing by shoots sprouting from roots.
The bark is ash-gray and scaly, flaking similarly to wild fl cherry, but more so.

Three exemplary experimental methods are described herein for performing QEA.TM.: a preferred method utilizing a novel RE/ligase/amplification procedure; a PCR based method; and a method utilizing a removal means, preferably biotin, for removal of unwanted DNA fragments.
Also useful to minimize noise in colony calling are improved hybridization detection methods.
Further by using variously sized and shaped particles with different light scattering properties, multiple probe hybridizations can be detected from one colony.

The adult stem cells referred to as mesenchymal stem cells or marrow stromal cells (MSCs) provide a convenient system for examining differentiation in culture.
The cells can readily be prepared as single cell-derived colonies and the clonal colonies can be differentiated into osteoblasts, adipocytes or chondrocytes in culture.
The cells expand rapidly and therefore the number of cells required for assays is non-limiting.

Under low magnification, healthy colonies appear white, while colonies that have "balled up" in solution and then settled appear yellow; these latter colonies mimic a developing embryo and will likely differentiate.
When injected into an ischemic heart, these cells or their clonal progeny reconstitute well-differentiated myocardium, formed by blood-carrying new vessels and myocytes with the characteristics of young cells, encompassing approximately 70% of the ventricle.

The effect of ras signaling on the smooth muscle cell growth factor response was studied using rat aortic A10 smooth muscle cells transfected with a plasmid that encoded the RGL2-RBD.
RGL2-RBD transfection resulted in a 12-fold reduction in the number of clonal colonies that were obtained after selection, and dramatically slowed cell cycle progression.
