The aim of the study was to investigate the attractiveness to herbivores and parasitoids of two cultivars of Brassica oleracea L., namely, B. oleracea variety acephala (kale) and B. oleracea variety capitata (cabbage), that exhibit differences of morphological and biochemical traits. To this end, field samplings were replicated at seven localities in Galicia (northwestern Spain). Three speciali...

Crassulacean acid metabolism (CAM) was investigated in leaves and stems of the succulent C(4) dicot Portulaca oleracea L. Diurnal acid fluctuations, CO(2) gas exchange, and leaf resistance were monitored under various photoperiod and watering regimes. No CAM activity was seen in well watered plants grown under 16-hour days. Under 8-hour days, however, well watered plants showed a CAM-like patte...

Effluent from electroplating industry contains various heavy metals like Cd, Cr, Cu, Ni and Zn, which are used in electroplating process of industry. Effluent was slightly greenish in colour and pungent in odour. Physico-chemical properties like total suspended solids (TSS), total solids (TS), alkalinity, Biological oxygen demand (BOD), and Chemical oxygen demand (COD) showed higher values in e...

Development of the cauliflower phenotype in Arabidopsis thaliana requires mutations at both the CAULIFLOWER and APETALA1 loci. BoAP1 is the Brassica oleracea orthologue to the Arabidopsis AP1 gene, and is present in two copies in Brassica genomes. The BoAP1-A gene appears to encode a full-length protein, but BoAP1-B alleles in B. oleracea contain insertions that lead to premature translation te...

Introduction: Portulaca oleracea is a common plant used in South Indian culinary; recently there is increase in research publication on various biological activities of the medicinal herb. The safety of the medicinal herb well accounted by its widespread accepted use of natives yet scientific evaluation on the safety of the herb is not reported. Aim To scientifically evaluate the toxicity profi...

Abstract. Bailly C. 2021. Review: Natural products isolated from Portulaca oleracea (purslane, Ma-Chi-Xian): Focus on oleraciamides and oleracones. Nusantara Bioscience 13: 202-210. The plant L., known as purslane in English Ma-Chi-Xian Chinese, is largely used traditional medicine to treat a variety of diseases conditions, including dysentery, urinary tract dysfunctions, post-partum bleeding. ...

Severe root rot was observed in fields of cabbages (Brassica oleracea L.) in 2015 in China. Cardinal symptoms of this disease included root rot and wilting leaves. A fungus was isolated from diseased tissues consistently. Based on the morphological features and molecular analysis of the ITS-5.8S rDNA and D1/D2 domain of the 28S rRNA gene, it was identified as Plectosphaerella cucumerina. This i...

A procedure for isolating spinach (Spinacia oleracea L.) leaf peroxisomes in 0.25 molar sucrose solution by Percoll density gradient centrifugation followed by removal of the Percoll by washing and centrifugation was established. The preparation contains more than 90% peroxisomes as intact organelles with no detectable chlorophyll or cytochrome oxidase contamination. The peroxisomes are stable ...
