Intriguing expression patterns of 35S‐GFP and phas‐GUS transgenes in M. truncatula. The progressive loss of GFP expression in aerial parts as the plant aged was dramatic and occurred in each of the four transgenic plants studied. Consequently, transgene copy number does not appear to be a major factor.

Before staining, seedlings were fixed in 90% cold acetone for 1 h on ice, then washed in phosphate buffer for 1 h at room temperature. Seedlings were stained for 4–5 h (CYCB1;1::GUS) or overnight (pPILS6::GUS-GFP).

The green fluorescent protein (GFP) from the jellyfish Aequorea victoria is finding wide use as a genetic marker that can be directly visualized in the living cells of many heterologous organisms. We have sought to express GFP in the model plant Arabidopsis thaliana , but have found that proper expression of GFP is curtailed due to aberrant mRNA processing.

To express your gene with alternative promoters, or with other selectable markers for stable-cell generation, consider the pTracer™ vectors series. These vectors express the Cycle 3 Green Fluorescent Protein (Cycle 3 GFP) which has spectral excitation and emission wavelengths identical to wild-type GFP.

The current challenge, now that two plant genomes have been sequenced, is to assign a function to the increasing number of predicted genes. In Arabidopsis, approximately 55% of genes can be assigned a putative function, however, less than 8% of these have been assigned a function by direct experimental evidence. To identify these functions, many genes will have to undergo comprehensive
