A premature stop codon in BrFLC2 transcript results in early flowering in oilseed-type Brassica rapa plants.

Sujeong Kim, Jin A Kim, Hajeong Kang, Dong-Hwan Kim,

Nonsense-mediated mRNA decay (NMD)-mediated degradation of BrFLC2 transcripts is the main cause of rapid flowering of oilseed-type B. rapa 'LP08' plants. Many Brassica species require vernalization (long-term winter-like cooling) for transition to the reproductive stage. In the past several decades, scientific efforts have been made to discern the molecular mechanisms ... Read more >>
