Phosphinothricin acetyltransferase gene (pat) is an important selectable marker and also a key herbicide trait gene in several commercial products. In maize, the transformation frequency (TF) using pat as a selectable marker is the lowest among the c

Transgenic plants containing low copy transgene insertion free of vector backbone are highly desired for many biotechnological applications. We have investigated two different strategies for increasing the percentage of low copy events in Agrobacteri

In a construct containing a GUS reporter gene driven by the 5′ regulatory elements from rubi3, expression was enhanced 4-fold when a 20-nucleotide (nt) GUS 5′ untranslated sequence was replaced with 9 nt sequences derived from rubi3′s second ex

We have developed a method by which remarkably higher efficiencies of transient and stable transformation were achieved in bombardment transformation of plants. Over fivefold increase in transient gus gene expression was achieved when rice or maize s

Introns are important sequence elements that modulate the expression of genes. Using the GUS reporter gene driven by the promoter of the rice (Oryza sativa L.) polyubiquitin rubi3 gene, we investigated the effects of the 5' UTR intron of the rubi3 ge

Introns play a very important role in regulating gene expression in eukaryotes. In plants, many introns enhance gene expression, and the effect of intron-mediated enhancement (IME) of gene expression is reportedly often more profound in monocots than

Tall fescue (Festuca arundinacea Schreb.) is an open-pollinated, perennial, cool-season turf and forage grass species of great economic importance. The main problems of maintenance of tall fescue, and many other turfgrasses, are two severe fungal dis

An 808 bp promoter from a rice polyubiquitin gene, rubi3, has been isolated. The rubi3 gene contained an open reading frame of 1,140 bp encoding a pentameric polyubiquitin arranged as five tandem, head-to-tail repeats of 76 aa. The 1,140 bp 5' UTR in
