Sucrose is the principal transported product of photosynthesis from source leaves to sink organs. SUTs/SUCs (sucrose transporters or sucrose carriers) and SWEETs (Sugars Will Eventually be Exported Transporters) play significant central roles in phloem loading unloading. are key players translocation associated with crop yields. The SUT/SUC SWEET genes have been characterized several plant species, but a comprehensive analysis these two gene families oilseed rape has not yet reported. In our...

Abstract Rapeseed (Brassica napus) is one of the important oil crops worldwide. Its production often threatened by drought stress. Here, we identify a transcription factor (BnaA9.NF-YA7) that negatively regulates tolerance through genome-wide association study in B. napus . The presence two SNPs within CCAAT cis element leads to downregulation BnaA9.NF-YA7 expression. In addition, M63I (G-to-C) substitution transactivation domain can activate low level expression BnaA4.DOR , which an...

Seed coat color is an extremely important breeding characteristic of Brassica napus. To elucidate the factors affecting genetic architecture seed color, a genome-wide association study (GWAS) was conducted with diversity panel comprising 520 B. napus cultivars and inbred lines. In total, 22 single-nucleotide polymorphisms (SNPs) distributed on 7 chromosomes were found to be associated color. The most significant SNPs in 2014 near Bn-scaff_15763_1-p233999, only 43.42 kb away from...

Abstract Background Soybean is a globally important legume crop that provides primary source of high-quality vegetable protein and oil. Seed content (SPC) valuable quality trait controlled by multiple genes in soybean. Results In this study, we performed quantitative loci (QTL) mapping, QTL-seq, RNA sequencing (RNA-seq) to reveal the controlling soybean using high variety Nanxiadou 25. A total 50 QTL for SPC distributed on 14 chromosomes except 4, 12, 14, 17, 18, 19 were identified mapping...

Mei, Prunus mume Sieb. et Zucc., is an ornamental plant popular in East Asia and, as important member of genus Prunus, has played a pivotal role systematic studies the Rosaceae. However, genetic architecture botanical traits this species remains elusive. This paper represents first genome-wide mapping study quantitative trait loci (QTLs) that affect stem growth and form, leaf morphology anatomy intraspecific cross derived from two different mei cultivars.
