Lipoxygenases in early Brassica napus germination.
We have identified transcripts of two lipoxygenase (LOXs) from 3-day-germinated etiolated cotyledons. One encodes a soluble and the other encodes a plastid LOX. They are 2520 bp and 2676 bp in size, respectively. Antibodies raised against the C-terminal 500 amino acids of the plastid LOX recognize a 90 kDa LOX in 5-day-old etiolated and green cotyledons. In mature leaves a LOX of 95 kDa is dete...
متن کاملProteomic Dissection of Seed Germination and Seedling Establishment in Brassica napus
The success of seed germination and establishment of a normal seedling are key determinants of plant species propagation. At present, only a few studies have focused on the genetic control of seed germination by using a proteomic approach in Brassica napus. In the present study, the protein expression pattern of seed germination was investigated using differential fluorescence two-dimensional g...
متن کاملDisruption of Germination and Seedling Development in Brassica napus by Mutations Causing Severe Seed Hormonal Imbalance
The Brassica napus (oilseed rape) accession 1012-98 shows a disturbed germination phenotype that was thought to be associated with its lack of testa pigmentation and thin seed coat. Here, we demonstrate that the disturbed germination and seedling development are actually due to independent mutations that disrupt the balance of hormone metabolites and their regulators in the seeds. High-throughp...
متن کاملInfluence of seed colour on seed vigour in Brassica napus
Yellow seed colour in Brassica napus is a desired trait and has a strong impact on the quality of Canola and the processed products from the seed. The trait is accompanied with a thinner seed coat when compared to black seeds. For the model plant Arabidopsis thaliana, different mutants have been characterised showing the transparent testa phenotype to be associated with light seed colour due to...
متن کاملGenome-wide association mapping unravels the genetic control of seed germination and vigor in Brassica napus
Rapid and uniform seed germination is a crucial prerequisite for crop establishment and high yield levels in crop production. A disclosure of genetic factors contributing to adequate seed vigor would help to further increase yield potential and stability. Here we carried out a genome-wide association study in order to define genomic regions influencing seed germination and early seedling growth...
