This phylogenetic distribution suggests a clear origination and initial divergence of these repeat families in a rapa-oleracea common ancestor.
Blast analysis showed a B. rapa homologue of AtGA20OX3 (BrGA20OX3) in a B. rapa BAC clone KBrB004B12, which contains the sequence of the BrA9s marker located in LDRQTL1.
Our findings are also in line with a previous study, in which the genetic variation in a B. rapa core collection representing all morphotypes and geographical origins was analyzed based on molecular marker profiles [ 26, 27].
In A mice rapa-induced T-cell immunity defects correlated with lethal infection outcome (Goldberg et al., 2014).
890 SSR markers (designated as BrGMS) were developed and used for the construction of an integrated linkage map for the A genome in B. rapa and B. napus.
In B. rapa, a study examining flowering time in a backcross population between biennial and annual B. rapa suggested that most of the variation in flowering time between these life histories was due to FLC loci, including FLC1[ 77].
In this study, 102 AsA-related genes were found in B. rapa, a species that is the evolutionary product of a Brassica-specific WGT.
Thus, a single Brassicaceae CNS has six potential orthologous positions in B. rapa; a single Arabidopsis CNS has three potential homeologous positions.
In a dedicated B. rapa Agilent array, 61,546 probes (99.7% of total 61,654 probes) represent 42,162 Brassica rapa gene ID (called Bra ID).
Although many major QTL for different traits were detected in the B. rapa A subgenome, in comparison with B. napus, three traits, namely, plant height, flowering time, and seed yield, were commonly detected in the A subgenome of the two species and the homoeologous region of the same block in the C subgenome of B. napus.
Since Arabidopsis flowers are very small and produce very little nectar, the work described here provides clones and sequence information that may be useful for discovering genes involved in nectar production in B. rapa, a model system that produces relatively large volumes of floral nectar.
