UPF1 RNA helicase plays a central role in nonsense-mediated mRNA decay (NMD), which specifically recognizes aberrant mRNAs containing premature termination codons and targets them for degradation. Although NMD factors are highly conserved among eukaryotes, little is known about the role of NMD in plant growth and development. The lba1 mutant of Arabidopsis thaliana with a Gly(851)-->Glu missense mutation in AtUPF1 yielded seeds that were on average 22% longer in the long axis and 35% heavier… CONTINUE READING
