Dinitroaniline herbicides are antimicrotubule drugs that bind to tubulins and inhibit polymerization. As a result of repeated application of dinitroaniline herbicides, highly resistant and intermediately resistant biotypes of goosegrass (Eleusine indica) developed in previously wild-type populations. Three alpha-tubulin cDNA classes (designated TUA1, TUA2,(More)
We have shown by several independent criteria that actin is encoded by a very large and complex superfamily of genes in Petunia. Several cDNA and genomic probes encoding actins from diverse organisms (Dictyostelium, Drosophila, chicken and soybean) hybridize to hundreds of restriction fragments in the petunia genome. Actin-hybridizing sequences were(More)
Phylogenetic relationships in the genus Eleusine (Poaceae: Chloridoideae) were investigated using nuclear ITS and plastid trnT-trnF sequences. Separate and combined data sets were analyzed using parsimony, distance, and likelihood based methods, including Bayesian. Data congruence was examined using character and topological measures. Significant data(More)
The Mitchell variety of Petunia hybrida possesses a superfamily of actin genes which contains between 100 and 200 members that can be divided into at least six highly divergent subfamilies. The segregation of restriction fragment length polymorphisms among 96 plants from two backcrosses between the Violet 23 and Red 51 Petunia varieties and the Violet 23 x(More)
Inheritance of resistance to the anti-microtubule dinitroaniline herbicides was investigated in a goosegrass biotype displaying an intermediate level of resistance (I). Reciprocal crosses were made between the I biotype and previously characterized susceptible (S) or resistant (R) biotypes. Eight F(1) hybrids were identified, and F(2) populations were(More)
The lability of Rubisco activase function is thought to have a major role in the decline of leaf photosynthesis under moderate heat (<35°C). To investigate this further, we characterized Rubisco activase and explored its role in the previously demonstrated thermal acclimation and inhibition of two genotypes of Acer rubrum originally collected from Florida(More)
A partial cDNA for the ribosomal S28 gene from sunflower was initially cloned and identified to be down-regulated by high salinity, using differential display reverse transcriptase-polymerase chain reaction (PCR). Using this sequence, a 502-base pair (bp) full-length cDNA was cloned by rapid amplification of cDNA ends. This cDNA (designated Ha-RPS28)(More)
We report a simple and efficient method, which combines restriction endonuclease digestion and deoxynucleotide tailing, for cloning unknown genomic sequences adjacent to a known sequence. Total genomic DNA is partially digested with the frequent-cutting restriction enzymeNla III. A homo-oligomeric cytosine tail is added by terminal transferase. The tailed(More)
