pokeweed

or

pokeberry,

tall, bushy perennial herb (Phytolacca americana) native to North America but cultivated and naturalized in Europe. The long clusters of white flowers are followed by purplish black flattened berries, whose crimson juice has been used as ink and to color wines but is considered poisonous. The dried roots are sometimes used as an emetic or purgative; the young shoots are used for greens or eaten like asparagus. The plant is also called poke, inkberry, and garget. Pokeweed is classified in the division MagnoliophytaMagnoliophyta
, division of the plant kingdom consisting of those organisms commonly called the flowering plants, or angiosperms. The angiosperms have leaves, stems, and roots, and vascular, or conducting, tissue (xylem and phloem).

The cells were incubated for 96h with both VA-E at 0, 10, 100 and 1000 [micro]g/ml, interleukin-6 at 1000 U/ml, and pokeweed mitogen and phytohaemagglutinine at 2.5 [micro]g/ml.
Transgenic creeping bentgrass plants expressing three forms of ribosome-inactivating pokeweed antiviral proteins (PAP) were generated to increase the resistance to dollar spot disease caused by the fungal pathogen Sclerotinia homoeocarpa ET.
However, when the cells, including those apparently negative for HCV RNA, were ex vivo treated with mitogens known to activate different immune cell subsets, e.g., phytohemagglutinin (PHA) to stimulate T cells, pokeweed mitogen (PWM) to induce B and T cells, and lipopolysaccharide (LPS) to activate monocytes and B cells, HCV RNA was detected in all of the individuals.
High-dose LPS (1 ng/mL) or pokeweed mitogen-induced TNF-[alpha] production by peripheral whole blood cultures was significantly lower when stimulated immediately compared with delayed stimulation after 16 hours of incubation.

In addition, bare ground space allows various seeds found in the s eed bank such as ragweed (Ambrosia artemisiifolia), partridge pea (Cassia fasiculata), beggar's lice (Desmodium obtusum), blackberries (Rubus spp.), and pokeweed (Phytolacca americana) to germinate, and produce a valuable food source (seeds and soft mast) for many bird species, including northern bobwhites.
They vary in size from the 1.5m (5ft) pokeweed, Phytolacca americana, with spikes of glistening black fruits, though they are poisonous, to little lily-of-the-valley, which sometimes produces red berries - remarkably large when compared with the tiny flowers - and often outlasting the leaves.
The blastogenic responses to pokeweed mitogen and PHA were significantly reduced (p<.05) for up to 60 minutes after the injection.
