Intact chloroplasts isolated from leaves of eight species of 16:3 and 18:3 plants and chromoplasts isolated from Narcissus pseudonarcissus L. flowers synthesize galactose-labeled mono-, di-, and trigalactosyldiacylglycerol (MGDG, DGDG, and TGDG) when incubated with UDP-[6-(3)H]galactose. In all plastids, galactolipid synthesis, and especially synthesis of DGDG and TGDG, is reduced by treatment ...

Spinach (Spinacia oleracea L.) is an economically important green leafy vegetable crop. In this study, we performed deep transcriptome sequencing for nine spinach accessions: three from cultivated S. oleracea, three from wild S. turkestanica and three from wild S. tetrandra. A total of approximately 100 million high-quality reads were generated, which were de novo assembled into 72,151 unigenes...

The tomato industry in South Florida (USA) is seriously affected by recently emerging Tomato chlorotic spot virus (TCSV). Western flower thrips, Frankliniella occidentalis (Pergande), and common blossom schultzei (Trybom) (Thysanoptera: Thripidae), are the two known vectors of TCSV Florida. In present study, presence thrips 24 flowering ornamental plant species was observed vectors, as well mel...

BACKGROUND Diabetes is a major public health concern. In spite of continuous new drug development to treat diabetes, herbal remedies remain a potential adjunct therapy to maintain better glycemic control while also imparting few side-effects. Portulaca oleracea has been traditionally used to manage several diseases due to the anti-oxidant and anti-atherogenic effects it imparts. To better under...

GGPPS (geranylgeranyl pyrophosphate synthase) is a crucial enzyme in the terpene biosynthesis pathway. Terpenoids play essential roles chlorophyll and development of cabbage (Brassica oleracea L. var. capitata L.), major cruciferous vegetable worldwide. However, limited information available regarding B. genes. In this study, we examined 10 BoGGPPS genes from genome. The subcellular localizatio...

The chromosomes of Arabidopsis thaliana and Brassica oleracea have been extensively rearranged since the divergence of these species; however, conserved regions are evident. Eleven regions of conserved organization were detected, ranging from 3.7 to 49.6 cM in A. thaliana, spanning 158.2 cM (24.6%) of the A. thaliana genome, and 245 cM (29.9%) of the B. oleracea genome. At least 17 translocatio...

Nitrite reduction in either whole, isolated spinach chloroplasts (Spinacia oleracea L.) or in reconstituted spinach chloroplasts is stimulated by a short period of photosynthetic CO(2) fixation in the light prior to nitrite addition. With reconstituted chloroplasts, a similar stimulation can be obtained in nitrite reduction without CO(2) fixation by the addition of dihydroxyacetone phosphate or...

Portulaca oleracea L. is a medicinal plant find in Europe and Asia. This plant contains valuable secondary metabolite such as noradrenalin. Naturally the wild plant produce small amount of this secondary metabolites so induction of hairy roots can be useful to increase its production. In our research Agrobacterium rhizogenes strain AR15834 was used to induce hairy roots in the two-week leaf exp...

The environmental and financial costs of using inorganic phosphate fertilizers to maintain crop yield and quality are high. Breeding crops that acquire and use phosphorus (P) more efficiently could reduce these costs. The variation in shoot P concentration (shoot-P) and various measures of P use efficiency (PUE) were quantified among 355 Brassica oleracea L. accessions, 74 current commercial cu...
