Summary: The study found that the induction levels of secondary dormancy (SD) at sub- and supra-optimal temperatures varied among different rapeseed cultivars, and the impact of light conditions on germination and thermo-dormancy was significant. Seed mortality increased with rising temperatures in low SD potential cultivars.

Summary: Interspecific crosses between Brassica rapa and B. napus result in transcriptome shock in the developing seeds, leading to overall changes in gene expression patterns. The hybrids show expression bias towards B. rapa and significant changes in key transcription factors, which may be responsible for phenotype change.

Summary: Interspecific hybridization is common in nature and has great potential in agricultural systems. However, it can also lead to the escape of transgenes in genetically modified crops, posing risks to unintended plants. This review focuses on the interspecific hybridization and transgene escape of Brassica napus and B. rapa, aiming to better understand the environmental impact of interspecific hybrids and effectively manage transgene escape.

Summary: Seaweed polysaccharides have been proven to be more effective than synthetic commercial fertilizers in promoting plant growth. This study extracted polysaccharides from different seaweeds and examined their impact on Brassica napus L. seed germination. Carrageenan showed the best results in seedling growth and germination percentage, which may be attributed to its sulphation level, pH and conductivity.

Summary: Dormancy in canola is a complex process influenced by various factors including genetics, physiological characteristics, environmental conditions, and farming practices. Seed dormancy may contribute to poor stand establishment of planted canola, as it is closely related to germination. Secondary dormancy in canola seed can be induced under adverse environmental conditions such as low temperature or low light, leading to the persistence of volunteer canola seed in the soil seedbank. Genetics, plant hormones, seed composition, and maternal environmental conditions all play a role in influencing dormancy levels in canola. Farming practices, such as harvest timing and tillage regimes, can unintentionally affect secondary dormancy of canola seed in the seedbank. Overall, reducing secondary dormancy in canola cultivars is feasible but requires consideration of all interacting factors.

Summary: The study found that mixing food waste compost with cow and horse manure can significantly improve the growth and yield of Komatsuna. Additionally, combining FWM with CWM and HM can increase the utility value of methane fermentation residues obtained from food waste as compost while reducing the use of chemical fertilizer.

Summary: This study investigated the effects of different temperature and water conditions on rapeseed seed germination and seedling growth. The findings showed that 20 degrees Celsius was the optimum temperature for seeds, water availability played a significant role in germination, and seed quantity and priming method had an impact on seedling growth.

Summary: The study analyzed the genetic characteristics of seed germination under drought stress in a Brassica napus double haploid population and determined the drought stress index using QTLs analysis. Results showed that root-to-shoot length ratio is an effective morphological trait in determining drought tolerance in seedling stage. 39 identified QTLs were integrated into 36 consensus QTLs, with 18 QTLs affecting the drought stress index of four traits.

Summary: This study successfully increased the genetic diversity of Brassica juncea by introgressing the A genome of Brassica rapa. New B. juncea germplasm with expanded phenotypic variations was developed, and the introgression of B. rapa segments was tracked using SNP markers. The results showed that the introgression of the B. rapa genome significantly increased the genetic diversity of B. juncea.

Summary: Mass selection is an effective method to modify the content of specific glucosinolates (GSLs) in Brassica crops. The selection process shows a linear regression model with a higher efficiency in reducing the targeted GSL than in increasing it. There is also an indirect response of selection in other parts of the plant, and the populations obtained by selection have similar or better agronomic performance than the original population.

Summary: This review discusses the impact of heat stress on the growth and development of Brassica napus, including its reproductive stages. Heat stress leads to impaired growth and reduced seed production in B. napus. The review explores the mechanisms of heat stress adaptation, key regulatory genes, alternative splicing, and epigenetic modifications in response to heat stress. Omics-based studies are also discussed to understand the effects of heat stress on yield and quality traits, and the regulatory networks involved. Knowledge gaps are identified, emphasizing the need for further research on the impact of heat stress on B. napus during its reproductive stages and the regulation of thermotolerance in this crop species.

Summary: Seed priming is an efficient and low-cost approach to increase crop yield and enhance salt stress tolerance by affecting endogenous polyamine metabolism in seed germination and early growth. The arginine decarboxylase pathway seems to be involved in PAs accumulation in primed seeds, and priming also significantly influences tyramine and ethylene accumulation.
