Nitrate reductase was found in leaves of apricot Prunus armeniaca, sour cherry P. cerasus, sweet cherry P. avium, and plum P. domestica, but not in peach P. persica, from trees grown in sand culture receiving a nitrate containing nutrient solution. Nitrate was found in the leaves of all species. Nitrate and nitrate reductase were found in leaves of field-grown apricot, sour cherry, and plum tre...

Las plantas medicinales se utilizan para la prevención, el tratamiento y cura de enfermedades, modo que su uso corresponde a una las formas cuidado salud más antiguas humanidad. En este estudio, comprobó actividad antimicrobiana in vitro extractos acuosos Coffea arabica, Tephrosia vogelii, Prunus persica Eugenia uniflora, sobre Dermatophilus congolensis. Para evaluar utilizó prueba difusión en ...

The current study was conducted in the animal house of Faculty Education for Girls / University Kufa, and aimed to know effect nano-extract (zinc oxide) seeds Prunus persica armeniaca on histological structure lungs male white rats with ages ranging (6-10) weeks weights (200-250 g). Which were divided into ten groups, each group included 5 rats. first is control second that treated P.persica pl...

Ribosome-inactivating proteins (RIPs) are widespread among higher plants of different taxonomic orders. In this study, we report on the RIP sequences found in the genome/transcriptome of several important Rosaceae species, including many economically important edible fruits such as apple, pear, peach, apricot, and strawberry. All RIP domains from Rosaceae share high sequence similarity with con...

Aldose-6-phosphate reductase (alditol 6-phosphate:NADP 1-oxidoreductase) was isolated and characterized from mature apple leaves (Malus domestica cv. Starkrimson). The enzyme was purified 79-fold. The enzyme catalyzed the following reversible reaction: d-glucose 6-phosphate + NADPH + H(+) right arrow over left arrow d-sorbitol 6-phosphate + NADP(+). No activity was detected when NAD(+) was subs...

Water in dormant peach (Prunus persica [L.] Batsch. var. ;Harbrite') flower buds deep supercooled. Both supercooling and the freezing of water within the bud axis and primordium as distinct components depended on the viability of the bud axis tissue. The viability of the primordium was not critical. Supercooling was prevented by wounding buds with a dissecting needle, indicating that bud struct...

DNA markers have useful applications in cultivar identification. A novel analysis approach called cultivar identification diagram (CID) was developed using DNA markers in the separation of plant individuals. This new strategy is less time- and cost-consuming, has reliable results, and was constructed for fingerprinting. Ten 11-mer primers were used to amplify the genotypes; all 95 peach g...

Anthocyanin accumulation is responsible for flower coloration in peach. Here, we report the identification and functional characterization of eight flavonoid-related R2R3-MYB transcription factors, designated PpMYB10.2, PpMYB9, PpMYBPA1, Peace, PpMYB17, PpMYB18, PpMYB19, and PpMYB20, respectively, in peach flower transcriptome. PpMYB10.2 and PpMYB9 are able to activate transcription of anthocya...

Pch313 was isolated as a cDNA whose RNA accumulated during the softening period of peach (Prunus persica L. Batsch) fruit development. To better understand the role of the gene, we compared the amount of pch313-related RNA detected during fruit softening and tissue wounding between cultivars with different softening characteristics. The cultivar that softened faster, "Bailey," had a significant...

Peach trees bear either white- or yellow-flesh fruit. We found that Japanese peach cultivars have two types of mutation in a carotenoid catabolic gene, CCD4: the insertion of a retrotransposon, and a frame shift in the microsatellite sequences of the first exon. CCD4 in yellow-flesh peaches was disrupted by these mutations.
