High quality genome sequence reveals important events during domestication of White Lupin
Prod 2019-88m BAP GEAPSI INRA; International audience; White lupin (Lupinus albus; 2n=50) is the only crop producing cluster roots, an outstanding developmental adaptation to low phosphate soils. We report a high-quality chromosome-scale assembly of white lupin genome, together with an extensive transcriptome data from ten different organs. We used singlemolecule real-time technology, in combination with short-reads sequencing and optical and genetic maps to have a successful assembly. The final assembly size is 443 Mb with a N50 of 17 Mb. About 98% of the assembled genome is included on the 25 pseudo-chromosomes. The structural annotation identified 38258 coding genes and 3,129 ncRNA, bein…

Identification of genes underlying frost tolerance within a pea QTL
Prod 2019-88dd BAP GEAPSI INRA; National audience; Seeding legumes in autumn would allow increasing and regulating yield, but requires to improve the level of frost tolerance in varieties, which motivates the interest in deciphering the genetic determinism of this trait. In pea (Pisum sativum L.), this character is controlled by a few quantitative trait loci (QTL) that were identified by the analysis of RIL populations derived from contrasted genotypes, such as Champagne (Ch, tolerant) x Térèse (Té, sensitive), or by association analysis [1,2,3]. We study a QTL located on the pea linkage group 6 (WFD6.1), which accounts for a large part of frost tolerance variability, making it a choice tar…
