Organ-Specific Stability of Two Lemna rbcS mRNAs Is Determined Primarily in the Nuclear Compartment.

It has previously been shown that the organ-specific expression of two members of the ribulose-1,5-bisphosphate carboxylase/oxygenase small subunit (rbcS) gene family is post-transcriptionally regulated in Lemna gibba. While both small subunit genes encoding SSU1 and SSU5B were transcribed at comparable levels in root and frond nuclei, SSU1 mRNA accumulated… CONTINUE READING
