Arabidopsis thaliana and Saccharomyces cerevisiae NHX1 genes encode amiloride sensitive electroneutral Na+/H+ exchangers.

Sodium at high millimolar levels in the cytoplasm is toxic to plant and yeast cells. Sequestration of Na(+) ions into the vacuole is one mechanism to confer Na(+)-tolerance on these organisms. In the present study we provide direct evidence that the Arabidopsis thaliana At-NHX1 gene and the yeast NHX1 gene encode low-affinity electroneutral Na(+)/H(+) exchangers. We took advantage of the abilit...

Two functional alpha-tubulin genes of the yeast Saccharomyces cerevisiae encode divergent proteins.

Two alpha-tubulin genes from the budding yeast Saccharomyces cerevisiae were identified and cloned by cross-species DNA homology. Nucleotide sequencing studies revealed that the two genes, named TUB1 and TUB3, encoded gene products of 447 and 445 amino acids, respectively, that are highly homologous to alpha-tubulins from other species. Comparison of the sequences of the two genes revealed a 19...

Arabidopsis thaliana GYRB3 Does Not Encode a DNA Gyrase Subunit

BACKGROUND DNA topoisomerases are enzymes that control the topology of DNA in all cells. DNA gyrase is unique among the topoisomerases in that it is the only enzyme that can actively supercoil DNA using the free energy of ATP hydrolysis. Until recently gyrase was thought to be unique to bacteria, but has now been discovered in plants. The genome of the model plant, Arabidopsis thaliana, is pred...

Functional expression of the extraplastidial Arabidopsis thaliana oleate desaturase gene (FAD2) in Saccharomyces cerevisiae.

The functional expression in yeast of the Arabidopsis thaliana FAD2 gene, encoding the extraplastidial oleate desaturase (1-acyl-2-oleoyl-sn-glycero-3-phosphocholine delta 12-desaturase) is reported. Dienoic fatty acids constituted up to 11% (w/w) of the total fatty acids in transformed Saccharomyces cerevisiae cells and were confirmed to be linoleic acid and delta 9, delta 12-hexadecadienoic a...

Isolation and characterization of temperature-sensitive mutations in the RAS2 and CYR1 genes of Saccharomyces cerevisiae.

The yeast Saccharomyces cerevisiae contains two ras homologues, RAS1 and RAS2, whose products have been shown to modulate the activity of adenylate cyclase encoded by the CYR1 gene. To isolate temperature-sensitive mutations in the RAS2 gene, we constructed a plasmid carrying a RAS2 gene whose expression is under the control of the galactose-inducible GAL1 promoter. A ras1 strain transformed wi...
