Heterosis holds great potential for improving yield, quality, and environmental adaptability in crop breeding, which suggests that hybrids can exhibit better performance in adapting to extreme environments. However, the epigenetic mechanisms of salt-tolerant heterosis in allopolyploid crop Brassica napus (AACC, 2n = 38), particularly chromatin accessibility, remain largely unexplored. We investigated the dynamics of chromatin accessibility and transcriptional reprogramming during a time course of salt exposure in Brassica napus hybridization.

(Pb), a causal agent of blackleg of rapeseed, is composed of several subspecies, including 'australensis' (Pba), 'brassicae' (Pbb) and 'canadensis' (Pbc). Besides rapeseed, Pb can infect many wild cruciferous plants (WCPs), such as flixweed () and pennycress (), which may become the infection source for blackleg of rapeseed. However, Pb on WCPs has not been well investigated in China.

Despite early domestication around 3000 BC, the evolutionary history of the ancient allotetraploid species Brassica juncea (L.) Czern & Coss remains uncertain. Here, we report a chromosome-scale de novo assembly of a yellow-seeded B.
