Reticulate evolution is characterized by occasional hybridization between two species, creating a network of closely related taxa below and at the species level. In the present research, we aimed to verify the hypothesis of the allopolyploid origin of hexaploid C. album s. str., identify its putative parents and estimate the frequency of allopolyploidization events. We sampled 122 individuals o...

We analyzed the structure and replication of the mitochondrial (mt) circular DNA plasmid mp1 (1309 bp) from the higher plant Chenopodium album(L.). Two dimensional gel electrophoresis (2DE) revealed the existence of oligomers of up to a decamer in addition to the prevailing monomeric form. The migration behavior of cut replication intermediates during 2DE was consistent with a rolling circle (R...

In Chenopodium album, leaf excision and light both increase urease (EC. 3.5.1.5) activity. Dithiothreitol (DTT), reduced glutathione (GSH), cysteine and diazoinedicarboxylic acid bis(N,N-dimethylamide) (diamide) activated the crude enzyme. In contrast, crude urease was inhibited by phenylmethylsulphonyl fluoride (PMSF) and Na-p -tosyl-L-lysine chloromethyl ketone HCl (TLCK), suggesting the pres...

Endofitne gljive žive unutar biljaka ne uzrokujući očite simptome bolesti. Korovi koji rastu u blizini poljoprivrednih polja mogu poslužiti kao alternativni domaćin ovih gljiva. Izolirali smo endofitne iz 6 vrsta korova, uobičajenih za istočnu Hrvatsku te bez očitih simptoma bolesti: Abutilon theophrasti, Amaranthus retroflexus, Ambrosia arthemisiifolia, Chenopodium album, Sorghum halepense i X...

five species of dominant halophyte plants including: salsola griffithii, chenopodium album, aeluropus logopoidies, alopecurus textillis and cardaria draba were sampled from sistan region at their late vegetative stage. the collected samples were dried at room temperature and ground, and their chemical components including: dry matter, organic matter, ash, crude protein, crude fat, as well as ce...

Lamb’s quarters goosefoot (with scientific name “Chenopodium album L.”) can absorb and purify heavy metals from environment. Cesium is one of pollutant and basic elements. Due to similarity to potassium, it can be absorbed by plants intensively. According to its absorption from the environment, cesium effect on anatomical and ontogenical structure of plant was studied. For this purpose, plant s...

The nitrite-reducing activity of the normal susceptible biotype of lambsquarters (Chenopodium album L.) was strongly inhibited by atrazine in the assay medium, both in the case of the in vivo assays of leaf discs in light, and in vitro photoreduction assays of crude extracts. In vitro assays of crude extracts with methylviologen or ferredoxin supplying the reducing potential were not inhibited ...
