The Molecular Basis of Kale Domestication: Transcriptional Profiling of Developing Leaves Provides New Insights Into the Evolution of a Brassica oleracea Vegetative Morphotype

Morphotypes of Brassica oleracea are the result a dynamic interaction between genes that regulate transition vegetative and reproductive stages those leaf morphology plant architecture. In kales, ornate leaves, extended phase, nutritional quality some characters potentially selected by humans during domestication. We used combination developmental studies transcriptomics to understand domestication syndrome kale. To identify candidate responsible for evolution domestic kale, we searched transcriptome-wide differences among three B. morphotypes. RNA-seq experiments were global pattern expressed mixture at one time in cabbage, rapid cycling kale line TO1000. identified gene expression patterns differ morphotypes estimate contribution morphotype-specific sets apart (3958 differentially genes). Differentially abundant all Genes involved morphology, architecture, defense, nutrition This allowed us set suggest may be important syndrome. Understanding is importance ultimately improve Cole crop production.
