Rosaceae is the most important fruit-producing clade, and its key commercially relevant genera (Fragaria, Rosa, Rubus and Prunus) show broadly diverse growth habits, fruit types and compact diploid genomes. Peach, a diploid Prunus species, is one of the best genetically characterized deciduous trees. Here we describe the high-quality genome sequence of(More)
A transglutaminase (TGase; EC activity, which shared many properties with the TGase activity of the Helianthus tuberosus chloroplast, was observed in the Zea mays L. chloroplast and in its fractions. This activity was found to be prevalent in thylakoids; bis-(glutamyl) spermidine and bis-(glutamyl) putrescine were the main polyamine conjugates(More)
The present study investigates the genetic determinism of flowering and maturity dates, two traits highly affected by global climate change. Flowering and maturity dates were evaluated on five progenies from three Prunus species, peach, apricot and sweet cherry, during 3-8 years. Quantitative trait locus (QTL) detection was performed separately for each(More)
Striking increases in fruit size distinguish cultivated descendants from small-fruited wild progenitors for fleshy fruited species such as Solanum lycopersicum (tomato) and Prunus spp. (peach, cherry, plum, and apricot). The first fruit weight gene identified as a result of domestication and selection was the tomato FW2.2 gene. Members of the FW2.2 gene(More)
Apple germplasm collections are increasingly appreciated as a repository for the genetic improvement of species, and their evaluation is an essential prerequisite for their utilization in apple breeding. A set of 418 apple genotypes, including 383 accessions from the Italian germplasm and 35 International cultivars as reference, was analyzed using 15 SSRs(More)
The light stimulation of transglutaminase (TGase EC activity was verified by incubating isolated chloroplasts of Helianthus tuberosus L. continuously or for alternate periods of light or dark (light/dark and dark/light). The first 10 min of incubation always represented the critical period. Light-harvesting complexes of photosystem II (LHCII) were(More)
Sharka is one of the most serious viral diseases affecting stone fruit species and, in apricot, resistance to its viral agent, the Plum Pox Virus (PPV), is conferred by one major quantitative trait locus (QTL), named PPVres for PPV resistance. Previous studies indicated that PPV-resistant cultivars and breeding progenies can be selected by using a set of(More)
European pear (Pyrus communis L.) is among the important fruit species for which only few genetic studies have been carried out. Available evidence indicates that simple sequence repeats (SSR) are very useful as molecular markers because they are codominant, highly polymorphic, abundant and reproducible. The present paper reports more than 100 apple SSR(More)
'Max Red Bartlett' is a red bud mutation of the yellow pear (Pyrus communis L.) cultivar 'Williams' (known as 'Bartlett' in North America). Anthocyanins are the most important pigments for red colour in fruits. Synthesis of anthocyanins is mediated by a number of well-characterized enzymes that include chalcone synthase (CHS), flavanone-3-hydroxylase (F3H),(More)
High-throughput DNA and RNA sequencing technologies have resulted in the successful identification of Single nucleotide polymorphisms (SNPs). In order to develop a large SNP set for wide application in apricot (Prunus armeniaca L.), we carried out RNA high-throughput sequencing (RNA-Seq) in two apricot genotypes, “Rojo Pasión” and “Z506-7.” After trimming(More)
