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

Jasmonate-induced transcriptional changes suggest a negative interference with the ripening syndrome in peach fruit.

Peach (Prunus persica L. Batsch) was chosen as a model to shed light on the physiological role of jasmonates (JAs) during fruit ripening. To this aim, the effects of methyl jasmonate (MJ, 0.40 mM) and propyl dihydrojasmonate (PDJ, 0.22 mM), applied in planta at different fruit developmental stages, on the time-course of ethylene production and fruit quality traits were evaluated. MJ-induced cha...

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

First genetic linkage map of chilling injury susceptibility in peach (Prunus persica (L.) Batsch) fruit with SSR and SNP markers

Peach and nectarine (Prunus persica L) are highly perishable; they ripen and deteriorate quickly at ambient temperature. Storage at low temperature (0–5oC) is a common strategy used to slow the ripening processes and extending shelf life. However, if susceptible varieties are held too long at a low temperature, they will not ripen properly and will develop chilling injury (CI) symptoms like mea...

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...

Association genetics of chilling injury susceptibility in peach (Prunus persica (L.) Batsch) across multiple years

Peach and nectarine (Prunus persica L.) are highly perishable; they ripen and deteriorate quickly at ambient temperature. Storage at low temperature (0-5 °C) is a common strategy used to slow the ripening processes and to extend shelf life. However, if susceptible varieties are held too long at a low temperature, they will not ripen properly and will develop chilling injury (CI) symptoms like m...
