Abstract
Winter rapeseed (Brassica rapa L.) is an important overwintering oilseed crop that is widely planted in northwest China and suffers chronic low temperatures in winter. So the cold stress becomes one of the major constraints that limit its production. The currently existing genomes limit the understanding of the cold-tolerant genetic basis of rapeseed. Here we assembled a high-quality long-read genome of B. rapa "Longyou-7" cultivar, which has a cold-tolerant phenotype, and constructed a graph-based pan-genome to detect the structural variations within homologs of currently reported cold-tolerant related genes in the "Longyou-7" genome, which provides an additional elucidation of the cold-tolerant genetic basis of "Longyou-7" cultivar and promotes the development of cold-tolerant breeding in B. rapa.

Abstract
Legumes (Fabaceae) are unique in their ability to enter into an elaborate symbiosis with nitrogen-fixing rhizobial bacteria. Rhizobia-legume (RL) symbiosis represents one of the most productive nitrogen-fixing systems and effectively renders the host plants to be more or less independent of other nitrogen sources. Due to high protein content, legumes are among the most economically important crop families. Beyond that, legumes consist of over 16,000 species assigned to 650 genera. In most cases, the genomes of legumes are large and polyploid, which originally did not predestine these plants as genetic model systems. It was not until the early 1990 th that Medicago truncatula was selected as the model plant for studying Fabaceae biology. M. truncatula is closely related to many economically important legumes and therefore its investigation is of high relevance for agriculture. Recently, quite a number of studies were published focussing on in depth characterizations of the M. truncatula proteome. The present review aims to summarize these studies, especially those which focus on the root system and its dynamic changes induced upon symbiotic or pathogenic interactions with microbes.
