Suspected 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 کاملPhenolic Glycosides from Capsella bursa-pastoris (L.) Medik and Their Anti-Inflammatory Activity.
A new sesquilignan glycoside 1, together with seven known phenolic glycosides 2-8 were isolated from the aerial parts of Capsella bursa-pastoris. The chemical structure of the new compound 1 was elucidated by extensive nuclear magnetic resonance (NMR) data (¹H- and 13C-NMR, ¹H-¹H correlation spectroscopy (¹H-¹H COSY), heteronuclear single-quantum correlation (HSQC), heteronuclear multiple bond ...
متن کاملCoalescent-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 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 کاملTransposable element evolution in the allotetraploid Capsella bursa-pastoris.
PREMISE OF THE STUDY Shifts in ploidy affect the evolutionary dynamics of genomes in a myriad of ways. Population genetic theory predicts that transposable element (TE) proliferation may follow because the genomewide efficacy of selection should be reduced and the increase in gene copies may mask the deleterious effects of TE insertions. Moreover, in allopolyploids, TEs may further accumulate b...
