stamen development and winter dormancy in apricot (prunus armeniaca).in temperate woody perennials, flower bud development is halted during the winter, when the buds enter dormancy. this dormant period is a prerequisite for adequate flowering, is genetically regulated, and plays a clear role in possibly adapting species and cultivars to climatic areas. however, information on the biological events underpinning dormancy is lacking. stamen development, with clear differentiated stages, appears as a good framework to put dormancy in a developmental context. here, st ...201121474504
ft-nir spectroscopy for the quality characterization of apricots (prunus armeniaca l.).the nondestructive assessment of apricot fruit quality (bora cultivar) was carried out by means of ft-nir reflectance spectroscopy in the wavenumber range 12000 to 4000 cm⁻¹. samples were harvested at four different ripening stages and scanned by a fiber optical probe immediately after harvesting and after a storage of 3 d (2 d at 4 °c and 1 d at 18 °c); the flesh firmness (ff), the soluble solids content (ssc), the acidity (a), and the titratable acidity (malic and citric acids) were then measu ...201021535540
antioxidant and antiradical capacities in apricot (prunus armeniaca l.) fruits: variations from genotypes, years, and analytical methods.the fruit quality parameters and antioxidant capacity (ferric reducing antioxidant power, frap) and total phenolic content (tpc) were determined in 27 apricot cultivars and hybrids of diverse origins. twenty one- to 35-fold variations were measured among frap and tpc values. besides genotype, harvest year also contributed significantly (p≤0.05) to the variations of tpc presumably due to the climatic differences between years. a subset of genotypes (15) was also analyzed for their antiradical act ...201621535583
non-tir-nbs-lrr resistance gene analogs in apricot (prunus armeniaca l.).genes encoding for proteins with nucleotide-binding site and leucine-rich repeat motifs (nbs-lrr) have been suggested to play a general role in plant defence mechanism. in prunus species, many tir (toll / interleukin-1 receptor), and only very few non-tir sequences were identified, which was explained either by the unequal distribution of tir/non-tir sequences in the prunus genome or by the incapability of primers in the amplification of non-tir rgas. the objective of this work was to check whet ...201121555269
[effects of high temperature on leaf photosynthetic characteristics and photosystem ii photochemical activity of kernel-used apricot].in order to explore the photosynthetic adaption mechanisms of kernel-used apricot under high temperature stress, gas exchange technique and chlorophyll fluorescence transient technique (jip-test) were adopted to study the leaf photosynthetic characteristics and photosystem ii (ps ii) photochemical activity of 4 year-old 'chaoren' (armeniaca vulgaris x sibirica) growing on horqin sandy land at 25 degrees c, 30 degrees c, 40 degrees c, and 50 degrees c. within a definite temperature range, and as ...201121657027
narrowing down the apricot plum pox virus resistance locus and comparative analysis with the peach genome syntenic region.sharka disease, caused by the plum pox virus (ppv), is one of the main limiting factors for stone fruit crops worldwide. only a few resistance sources have been found in apricot (prunus armeniaca l.), and most studies have located a major ppv resistance locus (ppvres) on linkage group 1 (lg1). however, the mapping accuracy was not sufficiently reliable and ppvres was predicted within a low confidence interval. in this study, we have constructed two high-density simple sequence repeat (ssr) impro ...201121722293

Dietary agents in the prevention of alcohol-induced hepatotoxicty: preclinical observations.Long term alcohol consumption is one of the important causes for liver failure and death. To complicate the existing problem there are no dependable hepatoprotective drugs and a large number of patients prefer using complementary and alternative medicines for treating and managing hepatic complications. Almost 25 centuries ago, Hippocrates, the father of medicine, proclaimed "Let food be thy medicine and medicine be thy food." Exploring the association between diet and health continues even toda ...201122119904

physical mapping of a pollen modifier locus controlling self-incompatibility in apricot and synteny analysis within the rosaceae.s-locus products (s-rnase and f-box proteins) are essential for the gametophytic self-incompatibility (gsi) specific recognition in prunus. however, accumulated genetic evidence suggests that other s-locus unlinked factors are also required for gsi. for instance, gsi breakdown was associated with a pollen-part mutation unlinked to the s-locus in the apricot (prunus armeniaca l.) cv. 'canino'. fine-mapping of this mutated modifier gene (m-locus) and the synteny analysis of the m-locus within the ...201222481163
