| a brachytic dwarfism trait (dw) in peach trees is caused by a nonsense mutation within the gibberellic acid receptor ppegid1c. | little is known about the genetic factors controlling tree size and shape. here, we studied the genetic basis for a recessive brachytic dwarfism trait (dw) in peach (prunus persica) that has little or no effect on fruit development. a sequencing-based mapping strategy positioned dw on the distal end of chromosome 6. further sequence analysis and fine mapping identified a candidate gene for dw as a non-functional allele of the gibberellic acid receptor gid1c. expression of the two gid1-like genes ... | 2016 | 26639453 |
| peaches preceded humans: fossil evidence from sw china. | peach (prunus persica, rosaceae) is an extremely popular tree fruit worldwide, with an annual production near 20 million tons. peach is widely thought to have origins in china, but its evolutionary history is largely unknown. the oldest evidence for the peach has been chinese archaeological records dating to 8000-7000 bp. here, we report eight fossil peach endocarps from late pliocene strata of kunming city, yunnan, southwestern china. the fossils are identical to modern peach endocarps, includi ... | 2015 | 26610240 |
| the crucial role of ppmyb10.1 in anthocyanin accumulation in peach and relationships between its allelic type and skin color phenotype. | red coloration of fruit skin is one of the most important traits in peach (prunus persica), and it is mainly due to the accumulation of anthocyanins. three myb10 genes, ppmyb10.1, ppmyb10.2, and ppmyb10.3, have been reported as important regulators of red coloration and anthocyanin biosynthesis in peach fruit. in this study, contribution of ppmyb10.1/2/3 to anthocyanin accumulation in the fruit skin was investigated in the japanese peach cultivars, white-skinned 'mochizuki' and red-skinned 'akat ... | 2015 | 26582106 |
| analysis of biochemical compounds and differentially expressed genes of the anthocyanin biosynthetic pathway in variegated peach flowers. | variegated plants are highly valuable in the floricultural market, yet the genetic mechanism underlying this attractive phenomenon has not been completely elucidated. in this study, we identified and measured different compounds in pink and white flower petals of peach (prunus persica) by high-performance liquid chromatography and liquid chromatography/mass spectrometry analyses. no cyanidin-based or pelargonidin-based compounds were detected in white petals, but high levels of these compounds w ... | 2015 | 26535657 |
| transcriptomic analysis of fruit stored under cold conditions using controlled atmosphere in prunus persica cv. "red pearl". | cold storage (cs) can induce a physiological disorder known as chilling injury (ci) in nectarine fruits. the main symptom is mealiness that is perceived as non-juicy fruit by consumers. postharvest treatments such as controlled atmosphere (ca; a high co2 concentration and low o2) have been used under cold conditions to avoid this disorder. with the objective of exploring the mechanisms involved in the ca effect on mealiness prevention, we analyzed transcriptomic changes under six conditions of " ... | 2015 | 26483806 |
| potassium contributes to zinc stress tolerance in peach (prunus persica) seedlings by enhancing photosynthesis and the antioxidant defense system. | zinc (zn) is considered to be a major industrial pollutant because excessive amounts can impair plant growth. in this paper, we found that peach 'yoshihime' seedlings are promising zn tolerant plants. however, heavy zn toxicity (2 mm) damaged plant performance by disrupting biochemical processes, including photosynthesis, proline production, and k(+) nutrition. notably, elevated external k(+) supply (10 mm) alleviated peach seedlings from zn toxicity, evidenced by enhanced photosynthesis, antiox ... | 2015 | 26345760 |
| genomic detection and characterization of a korean isolate of little cherry virus 1 sampled from a peach tree. | a peach tree (prunus persica) showing yellowing and mild mottle symptoms was analyzed using high-throughput rna sequencing to determine the causal agent. a total of nine contigs similar to little cherry virus 1 (lchv-1) were produced, and all the contigs showed nucleotide sequence identity (lower than 83 %) and query coverage (higher than 73 %) with lchv-1. the symptomatic peach sample was confirmed to be infected with lchv-1-like virus as a result of reverse transcription-polymerase chain react ... | 2015 | 26315329 |

| ppyuc11, a strong candidate gene for the stony hard phenotype in peach (prunus persica l. batsch), participates in iaa biosynthesis during fruit ripening. | high concentrations of indole-3-acetic acid (iaa) are required for climacteric ethylene biosynthesis to cause fruit softening in melting flesh peaches at the late ripening stage. by contrast, the fruits of stony hard peach cultivars do not soften and produce little ethylene due to the low iaa concentrations. to investigate the regulation of iaa accumulation during peach ripening [the transition from stage s3 to stage s4 iii (climacteric)], a digital gene expression (dge) analysis was performed. ... | 2015 | 26307136 |
| ultraviolet-b radiation applied to detached peach fruit: a study of free radical generation by epr spin trapping. | in peaches, phenolic compounds are the major sources of antioxidants, and cyanidin-3-o-glucoside is the main anthocyanin present, above all in the skin. anthocyanin content has been shown to increase after uv-b irradiation, which may be very harmful for all biological organisms due to the induction of the generation of reactive oxygen species (ros). peach fruits (cv.
