BACKGROUND Variegation in flower color is commonly observed in many plant species and also occurs on ornamental peaches (Prunus persica f. versicolor [Sieb.] Voss). Variegated plants are highly valuable in the floricultural market. To gain a global perspective on genes differentially expressed in variegated peach flowers, we performed large-scale transcriptome sequencing of white and red petals...

Abstract Peach is a popular and important tree fruit widely produced in the world, production of high-quality peach does require management pests diseases. In this review, major diseases from China, Spain, USA are described detail for benefit producers, consultants, researchers, other interested parties. Minor concern these countries also described. Current progress on pathogen resistance to ch...

The Peach Tree Short Life (PTSL) is a syndrome that causes severe damage to peach trees, usually between one and eight-years-old, which can lead the scion death. In Brazil, it has importance mainly in Rio Grande do Sul State, largest Brazilian producer. First reported Pelotas area, late 1970s, continues cause damage, with varying intensities among years. Several have been national international...

We investigated hydraulic conductance characteristics and associated dry matter production and distribution of peach trees grafted on different rootstocks growing in the field. A single scion genotype was grown on a low ('K146-43'), an intermediate ('Hiawatha') and a high ('Nemaguard') vigor rootstock. 'K146-43' and 'Hiawatha' rootstocks had 27 and 52% lower mean leaf-specific hydraulic conduct...

The response of the peach scion cultivars, Jerseyqueen, Redhaven, Compact Redhaven, and Rio Oso Gem and rootstocks 'Lovely and 'Nemaguard' to inoculation with Meloidogyne incognita was compared in vitro and in microplots. One or more parameters monitored in vitro correlated with at least one parameter monitored in microplots, 4 years after tree planting (1989). A range of responses was observed...
