| host suitability analysis of the bark beetle scolytus amygdali (coleoptera: curculionidae: scolytinae). | scolytus amygdali is a polyphagous insect pest that feeds on fruit trees and forest trees. our study assessed the host preference and reproductive potential of s. amygdali on four tree species: almond (prunus dulcis), apricot (prunus armeniaca), peach (prunus persica), and plum (prunus domestica). females of s. amygdali produced maternal galleries that were longer on peach than the other three trees, and female fecundity was highest on peach. females with longer maternal galleries produced more ... | 2015 | 25809539 |
| genome-wide identification and analysis of the type-b authentic response regulator gene family in peach (prunus persica). | the type-b authentic response regulator (arr-b) family members serve as dna-binding transcriptional regulators, whose activities are probably regulated by phosphorylation/dephosphorylation, resulting in the rapid induction of type-a arr genes. type-b arrs are believed to be involved in many biological processes, including cytokinin signaling, plant growth, and stress responses through a chaperone or by isomerization of proline residues during protein folding. the public availability of complete ... | 0 | 28351057 |

| novel gene-sequence markers for isolate tracking within monilinia fructicola lesions. | monilinia fructicola is a diverse pathogen of pome and stone fruits that causes severe economic losses each year. however, little is known about inoculum flow within or between orchards and pathogen establishment in an orchard, because few methods exist for detecting diversity or tracking isolates over time. ssr loci are an effective option, but may be confounded by a high degree of mutability and potential sensitivity to abiotic stress. | 0 | 28160377 |
| simulation of carbon allocation and organ growth variability in apple tree by connecting architectural and source-sink models. | plant growth depends on carbon availability and allocation among organs. qualitree has been designed to simulate carbon allocation and partitioning in the peach tree (prunus persica), whereas mapplet is dedicated to the simulation of apple tree (malus × domestica) architecture. the objective of this study was to couple both models and adapt qualitree to apple trees to simulate organ growth traits and their within-tree variability. | 2016 | 27279576 |

| micrornas in fruit trees: discovery, diversity and future research directions. | since the first description of micrornas (mirnas) 20 years ago, the number of mirnas identified in different eukaryotic organisms has exploded, largely due to the recent advances in dna sequencing technologies. functional studies, mostly from model species, have revealed that mirnas are major post-transcriptional regulators of gene expression in eukaryotes. in plants, they are implicated in fundamental biological processes, from plant development and morphogenesis, to regulation of plant pathoge ... | 2014 | 24750383 |
| evolution analysis of dof transcription factor family and their expression in response to multiple abiotic stresses in malus domestica. | as a family of transcription factors, dna binding with one figure (dof) proteins play important roles in various biological processes in plants. here, a total of 60 putative apple (malus domestica) dof genes (mddof) were identified and mapped to different chromosomes. chromosomal distribution and synteny analysis indicated that the expansion of the mddof genes came primarily from segmental and duplication events, and from whole genome duplication, which lead to more dof members in apples than in ... | 2018 | 28986315 |
