Potato Alternaria leaf blight is one of the economically most important disease in potato production worldwide. A recent study reported a quick method to distinguish main Alternaria pathogens A. tenuissima, A. alternata, and A. solani using partial histone H3 gene sequences. Using this method, our

Changes in DNA cytosine methylation and core histone multi-acetylation were determined in cell suspension cultures of potato (Solanum tuberosum L. cv. Russet Burbank) during 15 days of in vitro culture. Cell subculture induced a transient 33% decrease in genome-wide 5-methylcytosine (5mC) content

In this paper we analyzed β-aminobutyric acid (BABA)-primed epigenetic adjustment of potato cv. "Sarpo Mira" to Phytophthora infestans. The first stress-free generation of the potato genotype obtained from BABA-primed parent plants via tubers and seeds showed pronounced resistance to the pathogen,

The effects of post-harvest storage and dormancy progression on histone acetylation patterns were examined in potato (Solanum tuberosum L. cv. Russet Burbank) tubers. Storage of field-grown tubers at 3 degrees C in the dark resulted in the progressive loss of tuber meristem dormancy, defined as

The patatin multicopy gene family encodes the major storage protein in potato tubers and is organized as a single cluster in the potato genome. We sequenced a 154-kb bacterial artificial chromosome (BAC) clone containing a portion of the patatin gene cluster. Two putatively functional patatin genes

White potato tuber tissue reacts upon wounding with a rapid increase in activity of both chromatin-bound DNA-dependent RNA polymerase I and II as well as protein phosphokinase. This enhancement is more pronounced if 0.1 mM of the synthetic auxin 2,4-dichlorophenoxyacetic acid (2,4-D) is added

Late blight caused by Phytophthora infestans, is one of the most devastating diseases of potato, and was responsible for the death of millions of people during the Irish Potato Famine in the nineteenth century. Phytophthora infestans is a heterothallic oomycete that typically requires

Seven polyketides, including four new ones named as varilactones A-B (1-2) and wortmannilactones M-N (3-4), as well as three biogenetically related known wortmannilactones E, F and H (5-7), were isolated from the fungus Penicillium variabile HXQ-H-1, cultivated in potato-based medium with the

Telomeres, nucleoprotein structures at the ends of linear eukaryotic chromosomes, are crucial for the maintenance of genome integrity. In most plants, telomeres consist of conserved tandem repeat units comprising the TTTAGGG motif. Recently, non-canonical telomeres were described in several plants

The availability of genomic data in the last decade relating to different aphid species has allowed the analysis of the genomic variability occurring among such species, whereas intra-specific variability has hitherto very largely been neglected. In order to analyse the intra-genomic

We investigated how potato exposed to a chemical agent could activate nitric oxide (NO)-dependent events facilitating more potent defense responses to a subsequent pathogen attack. Obtained data revealed that all applied inducers, i.e., β-aminobutyric acid (BABA), γ-aminobutyric acid (GABA),

Potato (Solanum tuberosum L.) is grown worldwide as a major food crop. Potato early blight is an important disease caused by Alternaria solani (4). In 2011, diseased potato leaves with blight symptoms were collected from 21 sites (incidence averaged 60% for about 2,000 ha of potato fields examined)

Potato spindle tuber viroid (PSTVd) is a circular non-coding RNA of 359 nucleotides that replicates and spreads systemically in host plants, thus all functions required to establish an infection are mediated by sequence and structural elements in the genome. The PSTVd secondary structure contains 26
