Novel flowering time variation in the resynthesized polyploid Brassica napus.
Recent molecular data using resynthesized polyploids of Brassica napus established that genome changes can occur rapidly after polyploid formation. In this study we present data that de novo phenotypic variation for flowering time also occurs rapidly after polyploidization. Two initial polyploid plants were developed by reciprocal crosses of B. rapa and B. oleracea followed by chromosome doubli...
متن کاملCapturing sequence variation among flowering-time regulatory gene homologs in the allopolyploid crop species Brassica napus
Flowering, the transition from the vegetative to the generative phase, is a decisive time point in the lifecycle of a plant. Flowering is controlled by a complex network of transcription factors, photoreceptors, enzymes and miRNAs. In recent years, several studies gave rise to the hypothesis that this network is also strongly involved in the regulation of other important lifecycle processes ran...
متن کاملBrassica 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...
متن کاملEffects of stress and phenotypic variation on inbreeding depression in Brassica rapa.
Stressful environments are often said to increase the expression of inbreeding depression. Alternatively, Crow's "opportunity for selection" (the squared phenotypic coefficient of variation) sets a limit to how much selection can occur, constraining the magnitude of inbreeding depression. To test these hypotheses, we planted self- and cross-fertilized seeds of Brassica rapa into a factorial exp...
متن کاملProtoplast 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...
