Abstract
High demand for agricultural products together with the changing climate imposes an urgency for improving crop productivity and quality. The Brassica family has evolved as a globally significant oilseed crop due to its multifaceted application for edible oils, seed meals, and biodiesel production. However, its wide-scale crop production is limited due to the advent of several external stressors. Development of resilient Brassica crops requires recognition of the chromatin state complexes to fine tune the transcriptional machinery. Epigenetic modification through DNA methylation, histone modification, RNA directed gene silencing, and chromatin remodeling plays a major role in modulating flowering time, gametogenesis, embryogenesis, seed development and whole genome duplication to shape key agronomical traits. In conjunction, recent progress in the field of sequencing technologies and…
