Turnip mosaic potyvirus probably first spread to Eurasian brassica crops from wild orchids about 1000 years ago [PDF]

open access: yes, 2013
Turnip mosaic potyvirus (TuMV) is probably the most widespread and damaging virus that infects cultivated brassicas worldwide. Previous work has indicated that the virus originated in western Eurasia, with all of its closest relatives being viruses of ...

Further Investigation Into an Environmental Source for Aminorex

open access: yesDrug Testing and Analysis, EarlyView.
The results provide evidence that resedine is an intermediary compound between barbarin and aminorex in horses and that resedine can be used as a biomarker to eliminate the reporting of aminorex positives originating from the ingestion of plants from the Brassicaceae family.

Comparison of allelopathic effects of some brassica species in two growth stages on germination and growth of sunflower

open access: yesPlant, Soil and Environment, 2011
Members of Brassicaceae have been frequently cited as allelopathic crop. The toxic effect of Brassica spp. may be caused by hydrolysis products of glucosinolates that occur in substantial amounts in the vegetative parts of Brassica spp.

Quantification of avoidable yield losses in oilseed Brassica caused by insect pests [PDF]

open access: yesJournal of Plant Protection Research, 51(1): 38-43 (2011), 2017
A six year field study was conducted from 2001 2002 to 2006 2007 at Punjab Agricultural University, Ludhiana, India to study the losses in seed yield of different Brassica species (B. juncea, B. napus, B. carinata, B. rapa and Eruca sativa) by the infestation of insect pests. The experiment was conducted in two different sets viz. protected/sprayed and

Xanthomonas campestris pv. campestris (cause of black rot of crucifers) in the genomic era is still a worldwide threat to brassica crops [PDF]

open access: yes, 2012
Background Xanthomonas campestris pv. campestris (Xcc) (Pammel) Dowson is a Gram-negative bacterium that causes black rot, the most important disease of vegetable brassica crops worldwide. Intensive molecular investigation of Xcc is gaining momentum and

Use of rooted leaves for screening of Brassica germplasm response to clubroot (Plasmodiophora brassicae) and downy mildew (Hyaloperonospora parasitica)

open access: yesHorticultural Science, 2005
Rooted leaves and cotyledons of various cruciferous crops were used for the screening of Brassica germplasm response to two obligatory pathogens: clubroot (Plasmodiophora brassicae) and downy mildew (Hyalope-ronospora parasitica).

Potential Phytoextraction with in-vitro regenerated plantlets of Brassica juncea (L.) Czern. in presence of CdCl$_2$: Cadmium accumulation and physiological parameter measurement [PDF]

open access: yesarXiv, 2008
Heavy metal contamination of agricultural land is partly responsible for limiting crop productivity. Cd$^{2+}$ is known as a non-essentiel HM that can be harmful to plants even at low concentrations. Brassica juncea (L.) is able to accumulate more than 400 $\mu$g.g$^{-1}$ D.W.

Increased regeneration efficiency of _Brassica napus_ L. cultivars Star, Westar and Cyclone from hypocotyle and cotyledonary explants [PDF]

open access: yes, 2010
The comparative organogenesis of _Brassica napus_ L cultivars Cyclone, Star and Westar was studied. The cotyledonary explants gave a higher response to all the combinations of 0.5 mg/L 2,4-D and BAP (0.5, 1.0,1.5 and 2.0 mg/L} used for optimizing the ...

Transcriptome and organellar sequencing highlights the complex origin and diversification of allotetraploid Brassica napus

open access: yesNature Communications, 2019
Brassica napus, an allotetraploid crop, is hypothesized to be a hybrid from unknown varieties of Brassica rapa and Brassica oleracea. Despite the economic importance of B.
