Development of Brassica oleracea-nigra monosomic alien addition lines: genotypic, cytological and morphological analyses

“…Generally, the expounded analogous cellular pathways occurred in different forms of gene expressions in aneuploidy cells and affected the stereotypical antiproliferative response as the genes associated with the cell proliferation were largely downregulated and then the genes involved in the response to stress were upregulated to survive [ 50 ]. The MAALs disrupted the normal cell cycle and cell proliferation with the addition of alien chromosomes, and had phenotypic and growth difference [ 39 ]. From different pairwise comparisons between MAALs, only 13 co-regulated genes were detected and associated with negative proliferation or enhanced stress.…”

“…As a result of its better drought tolerance and resistance to fungal diseases, B. carinata is gaining ground in semi-arid areas of southern Europe, western Canada, Australia and India, and also serves breeding as the germplasm [ 35 ]. In particular, these MAALs were distinguishable morphologically from each other, as they expressed the characters from B. nigra differently [ 39 ]. The comprehensive transcriptome analysis of B. oleracea - nigra MAALs provided novel insights into the gene expression patterns of recipient C-subgenome to the individual B-subgenome chromosomes, and provided a deep understanding of the functional interplay between two parental genomes for the evolutionary formation of the allotetraploid B. carinata .…”
