Coalescent-based analysis distinguishes between allo- and autopolyploid origin in Shepherd's Purse (Capsella bursa-pastoris).
Polyploidization plays an important role in plant speciation. The most recent estimates report that up to 15% of angiosperm speciation events and 31% in ferns are accompanied by changes in ploidy level. Polyploids can arise either through autopolyploidy, when the sets of chromosomes originate from a single species, or through allopolyploidy, when they originate from different species. In this s...
متن کاملSuspected nitrite poisoning in pigs caused by Capsella bursa-pastoris (L.) Medik. ('herderstassie', shepherd's purse).
Nitrite poisoning in pigs was suspected when 4 of 18 pigs died in a piggery near Ellisras in the Northern Province. The pigs showed typical brownish discolouration of the blood at autopsy. It was established that they ingested vegetable tops and weeds from the adjacent garden as part of their daily ration. Of the available plants, only Capsella bursa-pastoris contained nitrites. The drinking wa...
متن کاملPerspective Research Progress in Cold Responses of Capsella bursa-pastoris
Plants respond to cold stress by modulating biochemical pathways and array of molecular events. Plant morphology is also affected by the onset of cold conditions culminating at repression in growth as well as yield reduction. As a preventive measure, cascades of complex signal transduction pathways are employed that permit plants to endure freezing or chilling periods. The signaling pathways an...
متن کاملCo-adaptation of seed dormancy and flowering time in the arable weed Capsella bursa-pastoris (shepherd's purse).
BACKGROUND AND AIMS The duration of the plant life cycle is an important attribute that determines fitness and coexistence of weeds in arable fields. It depends on the timing of two key life-history traits: time from seed dispersal to germination and time from germination to flowering. These traits are components of the time to reproduction. Dormancy results in reduced and delayed germination, ...
متن کاملInhibitory effect of Capsella bursa-pastoris extract on growth of Ehrlich solid tumor in mice.
The treatment of ICR mice with i.p. injections (0.14 g/kg/day) of the extract of Capsella bursa-pastoris herb (Cruciferae) caused 50 to 80% inhibition of the solid growth of Ehrlich tumor cells that had been inoculated into the s.c. tissue of the animals. The tumor lumps in the treated mice showed multifocal necroses and the infiltartion of host fibrous tissue cells. Experiments were also perfo...
