During 2012-2015 surveys in some orchards in Faraghe (Iran), a number of apricot trees showed symptoms resembling those associated with the phytoplasma disease known as European stone fruit yellows that are severe leaf roll, yellowing and die back. The presence of an infectious agent was confirmed by graft transmission experiments in which all the previously symptomless GF-677 (peach × almond) trees showed phytoplasma-type symptoms. The phytoplasma presence was confirmed by nested PCR assays using DNA extracted from samples from both field collected and graft-inoculated trees. The sequences of four nested PCR products from symptomatic apricot and experimentally graft-inoculated GF-677 trees were 100% identical to each other. RFLP and phylogenetic analyses carried out on these sequences allowed to cluster the strain infecting apricot trees in Iran with the16SrII-C subgroup phytoplasmas. This is the first report of a 16SrII-C phytoplasma associated with leaf roll and yellowing of the leaves in apricot trees.

Apricot trees, serving as critical agricultural resources, hold a significant role within the agricultural domain. Conventional methods for detecting pests and diseases in these trees are notably labor-intensive. Many conditions affecting apricot trees manifest distinct visual symptoms that are ideally suited for precise identification and classification via deep learning techniques.

Article Synopsis
- The study focuses on the role of the DELLA protein PmRGL2 in regulating dormancy and flowering in Prunus mume, a type of temperate fruit tree.
- Genetic and protein interaction analyses revealed that PmRGL2 interacts with PmFRL3, influencing the expression of flowering-related proteins like PmSVP and PmSVP-like.
- The proposed mechanism suggests that environmental signals like gibberellin (GA) and chilling temperatures affect the PmRGL2/PmFRL3 complex, leading to changes in flowering timing by regulating PmSVP and PmSVP-like activity.
In-vitro antifungal potential of myco versus bacteria synthesized ZnO NPs against chickpea and apricot pathogen.

Article Synopsis
- Chickpeas and apricots are economically significant crops that suffer from severe fungal infections, traditionally managed with chemical fungicides that pose health and environmental risks.
- Myco-synthesized (from fungi) and bacteria-synthesized zinc oxide (ZnO) nanoparticles were compared for their antifungal effectiveness against specific pathogens affecting these crops.
- Results showed that myco-synthesized ZnO nanoparticles exhibited better antifungal properties at lower concentrations, highlighting the need for further research to enhance their application in agriculture as sustainable alternatives to chemical fungicides.
Analysis of Kinship and Population Genetic Structure of 53 Apricot Resources Based on Whole Genome Resequencing.

Based on the single nucleotide polymorphism (SNP) markers developed by whole genome resequencing (WGRS), the relationship and population genetic structure of 53 common apricot () varieties were analyzed to provide a theoretical basis for revealing the phylogenetic relationship and classification of the common apricot. WGRS was performed on 53 common apricot varieties, and high-quality SNP sites were obtained after alignment with the "" apricot genome as a reference. Phylogenetic analysis, G matrix analysis, principal component analysis, and population structure analysis were performed using Genome-wide Complex Trait Analysis (GCTA), FastTree, Admixture, and other software.
