Intron recognition in Angiosperms is hypothesized to require AU-rich motifs within introns. In
this report we examined the role of AU-rich motifs in pre-mRNA processing. AU-rich …

Using a large set of plant gene sequences we compared individual introns to their flanking
exons. Both Zea mays and Arabidopsis thaliana introns are U-rich but display no apparent …

In vivo analyses using an autonomously replicating Agrobacterium/geminivirus vector have
enabled identification of AU‐rich intronic elements critical for 5′ and 3′ splice site …

The report that human growth hormone pre-mRNA is not processed in transgenic plant
tissues (A. Barta, K. Sommergruber, D. Thompson, K. Hartmuth, MA Matzke, and AJM …

In contrast to mammalian and yeast systems, the mechanism for intron recognition and
splice site selection in plant pre-mRNAs is poorly understood. Splice site sequences and …

Plant introns are generally short (< 200 nt) and AU-rich, and an elevated AU content is
necessary for efficient splicing. Further, an intron in some plant genes enhances gene …

The majority of eukaryotic mRNAs are produced from precursor mRNAs (pre-mRNAs) by the
excision of intervening sequences (introns) in a process called splicing. The basic …

Plant cells do not in general process the introns of transcripts expressed from introduced
vertebrate genes. By studying the processing of model introns in transfected plant …

We have found previously that the sequences important for recognition of pre‐mRNA introns
in dicot plants differ from those in the introns of vertebrates and yeast. Neither a conserved …

Pre-mRNA transcripts in a variety of organisms, including plants, Drosophila and
Caenorhabiditis elegans, contain introns which are significantly richer in adenosine and …
