Ultraperformance liquid chromatography coupled with negative electrospray tandem mass spectrometry (UPLC-ESI-MS/MS) was used to determine 7 hydroxy fatty acids in the pollen of Brassica campestris L. var. oleifera DC. All the investigated hydroxy fatty acids showed strong deprotonated molecular ions [M-H](-), which underwent two major fragment pathways of the allyl scission and the β-fission of...

The incorporation of the radioactivity from acetate-1-(14)C, acetate-2-(14)C, dl-methionine-1-(14)C, dl-methionine-2-(14)C, dl-methionine-3,4-(14)C, dl-homomethionine-2-(14)C, dl-allyl-glycine-2-(14)C, and dl-2-amino-5-hydroxyvalerate-2-(14)C into the aglycones of progoitrin, gluconapin, and glucobrassicanapin of maturing rape plants (Brassica campestris L.) was investigated. Radioactivity from...

Background: Although cetrimonium bromide is widely used for its bactericidal effects, the safety of cetrimonium bromide remains controversial. Therefore, the phytotoxicity of cetrimonium bromide was tested to evaluate its acute toxicity to plants and possible toxicity to other organisms and the ecosystem. Results: The germination rates of two test species, Lactuca sativa and Brassica campestris...

Polygalacturonase (PG) is one of the cell wall hydrolytic enzymes involving in pectin degradation. A comparison of two highly conserved duplicated PG genes, namely, Brassica campestris Male Fertility 26a (BcMF26a) and BcMF26b, revealed the different features of their expression patterns and functions. We found that these two genes were orthologous genes of At4g33440, and they originated from a ...

Inoculation of mature leaves of turnip (Brassica campestris) with the incompatible Xanthomonas campestris pv vitians resulted in the induction of beta-1,3-glucanase and chitinase/lysozyme (CHL) activity. No increase in the basal activity of beta-1,3-glucanase was observed after inoculation of leaves with heat- or rifampicin-killed X. c. vitians, Escherichia coli, or sterile water. Inoculation w...

Brassica rapa is a crucifer that is grown worldwide, mainly as a vegetable. The quality of B. rapa crops is highly affected by the disease caused by the bacteria Xanthomonas campestris pv. campestris (Xcc). Glucosinolates and phenolic compounds can confer resistance to Brassica crops against pests and diseases, but few works have been done to evaluate their role in Xcc resistance. The objective...

A field experiment was conducted during Rabi season of 2022 at the Crop Research Farm, Department Agronomy, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology And Sciences, Prayagraj (U.P.) India. To study Response Sulphur and Spacing on growth yield Toria. The treatments consist 15, 30, 45 kg/ha 20×15, 20×20, 25×20 cm. There were 10 each replicated thrice. soil e...
