Based on RFLP analysis, two evolutionary lineages for Brassica diploid species have been proposed. These are (I) the “nigra” lineage and (II) the “rapa/oleracea” lineage. The phylogenetic relationship of Raphanus species to these two lineages is still unclear because chloroplast and mitochondrial DNA genomic restriction site variation suggests that Raphanus is more closely related to the “rapa/...

To investigate the antiarrthritic activity of petroleum-ether extract of Portulaca oleracea. The petroleum-ether extract of Portulaca oleracea was subjected to preliminary phytochemical screening. Acute toxicity studies were carried out in Male Wistar rats and anti-arthritic activity by Fruends adjuant arthritis model. Phytochemical evaluation revealed the presence of alkaloids, tannins, flavon...

Wound healing is a complex process that aims to restore damaged tissue. Phytotherapeutics, such as cabbage, Brassica oleracea var. capitata (Brassicaceae), and sunflower, Helianthus annuus L. (Asteraceae) oil, are used as wound healers. Five circular wounds, each 12 mm in diameter, were made in the dorsolateral region of each rat. The animals were divided into four groups: balsam (B. oleracea);...

The protective action against oxidative stress of red cabbage (Brassica oleracea) extract was investigated. Diabetes was induced in male Wistar rats using streptozotocin (60 mg/kg body weight). Throughout the experimental period (60 days), diabetic rats exhibited many symptoms including loss of body weight, hyperglycemia, polyuria, polydipsia, renal enlargement and renal dysfunction. Significan...

Three fungi newly intercepted from importing plants were identified in 2004. They were Ascochyta chrysanthemi on Lactuca sativa from China, A. spinaciicola on Spinacia oleracea from Denmark, and Leptosphaerulina australis on Brassica oleracea var. capitata from China. The characters of these fungi were described and illustrated.

Miniature inverted-repeat transposable elements (MITEs) are ubiquitous, non-autonomous class II transposable elements. Here, we conducted genome-wide comparative analysis of 20 MITE families in B. rapa, B. oleracea, and Arabidopsis thaliana. A total of 5894 and 6026 MITE members belonging to the 20 families were found in the whole genome pseudo-chromosome sequences of B. rapa and B. oleracea, r...

Numerous studies using single nucleotide polymorphisms (SNPs) have been conducted in humans, and other animals, and in major crops, including rice, soybean, and Chinese cabbage. However, the number of SNP studies in cabbage is limited. In this present study, we evaluated whether 7,645 SNPs previously identified as molecular markers linked to disease resistance in the Brassica rapa genome could ...

Eleusine indica and Portulaca oleracea are two common weeds in peanut crops in southern Córdoba. Two chemicals are frequently used to control them, quizalofop for grasses and lactofen for dicots. The objective is to study the effects of quizalofop and lactofen on cuticle ultrastructure in E. indica and P. oleracea, respectively. In the lab, quizalofop was applied on E. indica and lactofen on P....

Correlation coefficients based on relative concentrations of 13 glucosinolates in the edible parts of 30 culth'ars were determined. Brussels sprouts (Brassica oleracea L. gemmifera group), cauliOower (8. oleracea L. botlJ·tis group), and either marrow-stem or smooth-leafed kale (B, oleracea L. aceplzala group) had similar glucosinolate patterns based on significant correlations (P < 0.01). The ...
