Identification of candidate genes for leaf size by QTL mapping and transcriptome sequencing in Brassica napus L.

Leaf is the main photosynthetic organ at the seedling stage of rapeseed and leaf size is a crucial agronomic trait affecting rapeseed yield. Understanding the genetic mechanisms underlying leaf size is therefore important for rapeseed breeding. In this study, QTL mapping for three traits related to leaf size, i.

Mining Candidate Genes for Leaf Angle in L. by Combining QTL Mapping and RNA Sequencing Analysis.

Leaf angle (LA) is an important trait of plant architecture, and individuals with narrow LA can better capture canopy light under high-density planting, which is beneficial for increasing the overall yield per unit area. To study the genetic basis and molecular regulation mechanism of leaf angle in rapeseed, we carried out a series of experiments. Quantitative trait loci (QTL) mapping was performed using the RIL population, and seven QTLs were identified.

Genome-Wide Association Study of Cadmium Accumulation at the Seedling Stage in Rapeseed ( L.).

Cadmium is a potentially toxic heavy metal to human health. Rapeseed ( L.), a vegetable and oilseed crop, might also be a Cd hyperaccumulator, but there is little information on this trait in rapeseed.

Molecular validation of multiple allele inheritance for dominant genic male sterility gene in Brassica napus L.

Dominant genic male sterility (DGMS) has been playing an increasingly important role, not only as a tool for assisting in recurrent selection but also as an alternative approach for efficient production of hybrids. Previous studies indicate that fertility restoration of DGMS is the action of another unlinked dominant gene. Recently, through classical genetic analysis with various test populations we have verified that in a DGMS line 609AB the trait is inherited in a multiple allelic pattern.
