RNAseq analysis of mutants in coding and non-coding transcription of phosphate genes in the yeast Saccharomyces cerevisiae.

In the yeast Saccharomyces cerevisiae phosphate starvation induces the expression of PHO genes, including PHO84, encoding an high-affinity phosphate transporter, and SPL2, encoding a regulatory protein. PHO84 is down-regulated by antisense transcription. Here, using strand-specific RNAseq the effect is studied of mutations related to sense and antisense transcription of phosphate genes.

The translocated virulence protein VirD5 causes DNA damage and mutation during -mediated transformation of yeast.

The soil bacterium is a preferred gene vector not only for plants but also for fungi. delivers a small set of virulence proteins into host cells concomitantly with transferred DNA (T-DNA) to support the transformation process. Here, we find that expression of one of these proteins, called VirD5, in yeast host cells causes replication stress and DNA damage.

Increased Agrobacterium-mediated transformation of Saccharomyces cerevisiae after deletion of the yeast ADA2 gene.

Agrobacterium tumefaciens is the causative agent of crown gall disease and is widely used as a vector to create transgenic plants. Under laboratory conditions, the yeast Saccharomyces cerevisiae and other yeasts and fungi can also be transformed, and Agrobacterium-mediated transformation (AMT) is now considered the method of choice for genetic transformation of many fungi. Unlike plants, in S.

Cell-to-cell heterogeneity of phosphate gene expression in yeast is controlled by alternative transcription, 14-3-3 and Spl2.

Dependent on phosphate availability the yeast Saccharomyces cerevisiae expresses either low or high affinity phosphate transporters. In the presence of phosphate yeast cells still express low levels of the high affinity phosphate transporter Pho84. The regulator Spl2 is expressed in approximately 90% of the cells, and is not expressed in the remaining cells.

Complete Sequence of Succinamopine Ti-Plasmid pTiEU6 Reveals Its Evolutionary Relatedness with Nopaline-Type Ti-Plasmids.

Agrobacterium tumefaciens is the etiological agent of plant crown gall disease, which is induced by the delivery of a set of oncogenic genes into plant cells from its tumor-inducing (Ti) plasmid. Here we present the first complete sequence of a succinamopine-type Ti-plasmid. Plasmid pTiEU6 is comprised of 176,375 bp with an overall GC content of 56.
