In the past, milk whey was only a by-product of cheese production, but currently, it has a high commercial value for use in the food industries. However, the regulation of whey management (i.e., storage and hygienic properties) has not been updated, and as a consequence, its microbiological quality is very challenging for food safety. The Next Generation Sequencing (NGS) technique was applied to s...

Biological systems show impressive adaptations at extreme environments. In extreme environments, directional selection pressure mechanisms acting upon mutational events often produce functional and structural innovations. Examples are the antifreeze proteins in Antarctic fish and their lack of hemoglobin, and the thermostable properties of TAQ polymerase from thermophilic organisms. During the pa...

Design and implementation of novel algorithms to integrate different DNA sequencing technologies for de novo genome assembly: Nannochloropsis as a test case
The advent of next generation sequencing technologies marked the beginning of a new era in the production of genomic data; nonetheless it also offered novel challenges to the bioinformatics community. While re- sequencing of genomes was made relatively easy and cheap, de novo assembly of eukaryotic genomes still presents significant hurdles.
In this thesis we attempted the application of a mixed-...

A deep survey of alternative splicing in grape reveals changes in the splicing machinery related to tissue, stress condition and genotype
Alternative splicing (AS) significantly enhances transcriptome complexity. It is differentially regulated in a wide variety of cell types and plays a role in several cellular processes. Here we describe a detailed survey of alternative splicing in grape based on 124 SOLiD RNAseq analyses from different tissues, stress conditions and genotypes.
We used the RNAseq data to upd...

Microbial dynamics during shelf-life of industrial Ricotta cheese and identification of a Bacillus strain as a cause of a pink discolouration
Dairy products are perishable and have to be preserved from spoilage during the food chain to achieve the desired shelf-life. Ricotta is a typical Italian soft dairy food produced by heat coagulation of whey proteins and is considered to be a light and healthy product. The shelf-life of Ricotta could be extended, as required by the international food trade market; however, heat resistant microflor...

SOLiD DNA sequences are typically analyzed using a reference genome, while they are not recommended for de novo assembly of genomes or transcriptomes. This is mainly due to the difficulty in translating the SOLiD color-space data into normal base-space sequences. In fact, the nature of color-space is such that any misinterpreted color leads to a chain of further translation errors, producing total...

Comprehensive transcript profiling of two grapevine rootstock genotypes contrasting in drought susceptibility links the phenylpropanoid pathway to enhanced tolerance.
In light of ongoing climate changes in wine-growing regions, the selection of drought-tolerant rootstocks is becoming a crucial factor for developing a sustainable viticulture. In this study, M4, a new rootstock genotype that shows tolerance to drought, was compared from a genomic and transcriptomic point of view with the less drought-tolerant genotype 101.14. The root and leaf transcriptome of bo...

Chromosome scale genome assembly and transcriptome profiling of Nannochloropsis gaditana in nitrogen depletion
Nannochloropsis is rapidly emerging as a model organism for the study of biofuel production in microalgae.
Here we report a high quality genomic assembly of Nannochloropsis gaditana, consisting of large contigs, up to 500 kbp long, and scaffolds that in most cases span the entire length of chromosomes. We identified 10,646 complete genes and characterized possible alternative transcripts. The a...

The sequencing of bisulfite-treated DNA (Bi-Seq) is becoming a gold standard for methylation studies. The mapping of Bi-Seq reads is complex and requires special alignment algorithms. This problem is particularly relevant for SOLiD color space, where the bisulfite conversion C/T changes two adjacent colors into 16 possible combinations. Here, we present an algorithm that efficiently aligns Bi-Seq ...

The transcriptional landscape of the deep-sea bacterium Photobacterium profundum in toxR mutant and its parental strain.
BACKGROUND: The deep-sea bacterium Photobacterium profundum is an established model for studying high pressure adaptation. In this paper we analyse the parental strain DB110 and the toxR mutant TW30 by massively parallel cDNA sequencing (RNA-seq). ToxR is a transmembrane DNA-binding protein first discovered in Vibrio cholerae, where it regulates a considerable number of genes involved in environme...

Investigating high-pressure adaptation of Photobacterium profundum SS9 by means of custom microarray
The deep sea is the most common habitat of the biosphere, as most Earth’s surface is covered by water with an average depth around 3000 meters. Photobacterium profundum, viable both at high (28 MPa) and atmospheric (0.1 MPa) pressure, is the model organism for high pressure adaptation. Its transmembrane transcription factor
ToxR is a pressure sensing transductor.

My first graphic design program has been CorelDraw 4.0, bundled with my inkjet printer I think, for Windows 3.1.
