Transcriptome profiling of ripening nectarine (Prunus persica L. Batsch) fruit treated with 1-MCP

A large-scale transcriptome analysis has been conducted using microPEACH1.0 microarray on nectarine (Prunus persica L. Batsch) fruit treated with 1-methylcyclopropene (1-MCP). 1-MCP maintained flesh firmness but did not block ethylene biosynthesis. Compared with samples at harvest, only nine genes appeared to be differentially expressed when fruit were sampled immediately after treatment, while...

JASMONATES NEGATIVELY INTERFERE WITH FRUIT DEVELOPMENT AND RIPENING IN PEACH (Prunus persica L. Batsch)

Jasmonates (JAs) are signal molecules which elicit stress responses through JAs-responsive genes; they are also involved in developmental processes, including fruit growth and ripening. In the present study, methyl jasmonate (MJ) and n-propyl dyhydrojasmonate (PDJ) were applied to peach trees at the S1, S3 and S4 phases. In all cases, both chemicals inhibited climacteric ethylene production and...

Quality oriented fruit breeding: Peach [Prunus persica (L.) Batsch]

Promising new tools for peach fruit quality breeding have been revised in this work. These tools included fruit quality evaluation through physical, chemical and sensorial parameters and post-harvest storage evaluation. The development of a feasible method for an early testing of peach selections generated in breeding programs is also well described together with the discussion of the inheritan...

Phenotypic diversity among local Spanish and foreign peach and 1 nectarine [ Prunus persica ( L . ) Batsch ] accessions

Segregation of peach and nectarine (Prunus persica (L.) Batsch) cultivars according to their organoleptic characteristics

Cultivar segregation according to the sensory perception of their organoleptic characteristics was attempted by using trained panel data evaluated by principal component analysis of four sources per cultivar of 23 peach and 26 nectarine cultivars as a part of our program to d a p c p o 9 a ( n t b t p ©
