HAPLOID FREQUENCIES IN BRASSICA NAPUS

Development of a haploid transformation system and overexpression of Phytochrome B gene in Brassica napus L

Brassica napus and diabetic complications

Introduction Chronic hyperglycemia results in diabetes associated complications development that is nowadays a global health disorder without efficient therapeutic application. Hyperglycemia, hyperlipidemia and oxidative damage are major reasons of diabetes accelerated renal and cardiovascular diseases. Hyperglycemia enhances oxidative injury of cellular macromolecules by making disruption of A...

Efficient Doubled Haploid Production in Brassica napus via Microspore Colchicine Treatment in vitro and Ploidy Determination by Flow Cytometry

An efficient microspore culture protocol was used to rapidly produce homozygous doubled haploid (DH) progeny of crosses between low erucic canola and high erucic resynthesized rapeseed (Brassica napus L.). Microspores of Canadian cultivars ‘Excel’ and ‘Profit’ as well as three F1 hybrids with the resynthetic line RS239 were treated with colchicine immediately after isolation. Flow cytometry was...

Protoplast Culture and Fusion between Brassica Carinata and Brassica Napus

In this study, attempts were made to select in vitro responsible genotypes and to fuse the isolated protoplasts of Brassica carinata and Brassica napus breeding lines (BC DH Dodolla, BC DH -1, BC DH-6 and BN OP-1, BN-SL03/04), obtained from our previous experiments. Combination of three different PEG concentrations (20%, 25% or 30%) and two different treatment durations (15 and 20 min.) were te...

Epigenetic QTL mapping in Brassica napus.

There is increasing evidence that epigenetic marks such as DNA methylation contribute to phenotypic variation by regulating gene transcription, developmental plasticity, and interactions with the environment. However, relatively little is known about the relationship between the stability and distribution of DNA methylation within chromosomes and the ability to detect trait loci. Plant genomes ...
