The execution of the apoptotic death program in metazoans is characterized by a sequence of morphological and biochemical changes that include cell shrinkage, presentation of phosphatidylserine at the cell surface, mitochondrial alterations, chromatin condensation, nuclear fragmentation, membrane blebbing and the formation of apoptotic bodies.

Cryptosporidium parvum and C. hominis are the most relevant species of this genus for human health. Both cause a self-limiting diarrhea in immunocompetent individuals, but cause potentially life-threatening disease in the immunocompromised. Despite the importance of these pathogens, only one reference genome of each has been analyzed and published. These(More)
Bocconia and Macleaya are the only genera of the poppy family (Papaveraceae) lacking petals; however, the developmental and genetic processes underlying such evolutionary shift have not yet been studied. We studied floral development in two species of petal-less poppies Bocconia frutescens and Macleaya cordata as well as in the closely related petal-bearing(More)
Here, we report the genome sequence and evidence for transcriptional activity of a virus-like element in the native Chilean berry tree Aristotelia chilensis. We propose to name the endogenous sequence as Aristotelia chilensis Virus 1 (AcV1). High-throughput sequencing of the genome of this tree uncovered an endogenous viral element, with a size of 7122 bp,(More)
CYCLOIDEA-like genes are involved in the symmetry gene network, limiting cell proliferation in the dorsal regions of bilateral flowers in core eudicots. CYC-like and closely related TCP genes (acronym for TEOSINTE BRANCHED1, CYCLOIDEA, and PROLIFERATION CELL FACTOR) have been poorly studied in Asparagales, the largest order of monocots that includes both(More)
Today, most data is unstructured and much of it is in text form. Over 90% of the data that exists today has been created in the last 2 years alone. This creates enormous issues for organisation's. While there is a wealth of information online in websites, news, social media, reports, articles, an organisation needs to be able to effectively mine, analyse(More)
Transcriptome analysis of a Cape gooseberry (Physalis peruviana) plant with leaf symptoms of a mild yellow mosaic typical of a viral disease revealed an infection with Potato virus X (PVX). The genome sequence of the PVX-Physalis isolate comprises 6435 nt and exhibits higher sequence similarity to members of the Eurasian group of PVX (~95 %) than to the(More)
Potato virus S (PVS) (genus Carlavirus, family Betaflexiviridae) is one of the most prevalent viruses in potato crops (Solanum tuberosum and S. phureja) around the world, causing reductions in crop yields between 10 and 20 %. Symptoms of PVS infection may include leaf mottling, rugosity of leaves, deepening of the veins and reductions in crop yields between(More)
Based on the results of a deep sequencing transcriptome study of tamarillo (Solanum betaceum), we report the genome sequence of a virus from this host plant. Since this probably represents a new member of the genus Potyvirus, the name tamarillo leaf malformation virus (TaLMV) has been proposed. Phylogenetic analysis reveals that TaLMV is the closest(More)
